DIRECTIONS FOR USE

Restricted Use Pesticide

It is a violation of federal law to use this product in a manner inconsistent with its labeling .

Do not apply this product in a way that will contact workers or other persons, either directly or through drift . Only handlers may be in the application block from the start of the application until the entry restricted period ends, and in the buffer zone during the buffer zone period .

For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation. Refer to supplemental labeling under “Agricultural Use Requirements” in this section for information about this standard .

All applicable directions, restrictions, precautions and WARRANTY are to be followed . This labeling must be in the user’s possession during application .

Agricultural Use Requirements Use this product only in accordance with its label and with the Worker Protection Stan-dard, 40 CFR 170. This Standard contains requirements for the protection of agricultural workers on farms, forests, nurseries, and greenhouses, and handlers of agricultural pesti-cides. It contains requirements for training, decontamination, notification, and emergency assistance .

For the entry restricted period and notification requirements, see the Entry Restricted Period and Notification sections of this labeling. PPE For Entry During the Entry-Restricted Period:

PPE for entry that is permitted by this label is listed in the Personal Protective Equipment (PPE) section of this label .

Terms used in this labeling Soil Fumigant Training Program: Certified applicator training that provides information on

(1) how to correctly apply the fumigant, including how to comply with new label require-ments; (2) how to protect handlers and bystanders; (3) how to determine buffer zone dis-tances; (4) how to complete an FMP and the post-application summary; (5) how to determine when weather and other site-specific factors are not favorable for fumigant application; (6) how to comply with required GAPs and how to document compliance with GAPs in the FMP;

and (7) how to develop and implement emergency response plans .

Fumigant Safe Handling Information: Information that must be provided annually to handlers that must include the following: (1) what fumigants are and how they work, (2) safe application and handling of soil fumigants, (3) air monitoring and respiratory protection requirements for handlers, (4) early signs and symptoms of exposure, (5) appropriate steps to take to mitigate exposures, (6) what to do in case of an emergency, and (7) how to report incidents .

Application Block: Area within the perimeter of the fumigated portion of a field or greenhouse (including furrows, irrigation ditches, roadways) . The perimeter of the application block is the border that connects the outermost edges of total area treated with the fumigant product .

Application Rate: The ratio of fumigant mass applied compared to the soil surface area (e .g ., lbs of product per acre) . The application rate is expressed on this labeling in terms of either the “treated area application rate” or the “broadcast equivalent application rate.” The “treated area application rate” relates to only the rate of fumigant applied to the portion of the field that is fumigated (e.g., rate within the bed or strips). The “broadcast equivalent application rate” relates to the rate of fumigant applied within the entire perimeter of the application block. For bedded and strip applications, the “broadcast equivalent application rate” must be calculated to determine the buffer zone distance required by this labeling.

Start of the Application: The time at which the fumigant is first delivered/dispensed into the soil in the application block .

Application is Complete: The time at which the fumigant has stopped being delivered/dispensed into the soil and the soil has been sealed on Day 1 (see the Water Requirements section)

Entry Restricted Period: This period begins at the start of the application and expires de-pending on the application method and if tarps are used when the tarps are perforated and removed . Entry into the application block during this period is only allowed for appropriately PPE-equipped handlers performing handling tasks. See the Entry Restricted Period and Notification section for additional information .

Buffer Zone: An area established around the perimeter of each application block . The buffer zone must extend outward from the edge of the application block perimeter equally in all directions .

Buffer Zone Period: Begins at the start of the application and lasts for a minimum of 48-hours after the application is complete . Non-handlers must be excluded from the buffer zone during the buffer zone period .

Difficult to Evacuate Sites: Pre-K to Grade 12 schools, state licensed daycare centers, nurs-ing homes, assisted living facilities, hospitals, in-patient clinics, and prisons .

Owner: Any person who has a present possessory interest (fee, leasehold, rental, or other) in an agricultural establishment . A person who has both leased such agricultural establish-ment to another person and granted that same person the right and full authority to manage and govern the use of such agricultural establishment is not an owner . See definition of “owner” in WPS (40 CFR §170.3).

Roadway: Portion of a street or highway improved, designed or ordinarily used for vehicular travel, exclusive of the sidewalk or shoulder even if such sidewalk or shoulder is used by persons riding bicycles . In the event a highway includes two or more separated roadways, the term roadway shall refer to any such roadway separately .

Representative Handling Task: For air monitoring, the locations and handler activities sam-pled must represent each handler's exposure occurring within the application block. For example, for an application consisting of a seven-handler crew (1 tractor driver, 1 tractor co-pilot, 4 shovelers, and 1 certified applicator supervising) two breathing zone samples could be collected: one sample for the tractor co-pilot and one sample for a downwind shoveler.

Results of previous sampling may indicate which tasks and locations are worst case and therefore representative of all handlers .

Use Method Restrictions The use of this product is restricted to the methods described in this label .

Certified Applicator Training Any certified applicator supervising a soil fumigant application must have successfully completed one of the soil fumigant training programs listed on the following EPA website www .epa .gov/fumiganttraining for the active ingredient(s) in this product . The training must be completed in the time frames listed on the website . The FMP must document the date and location where the soil fumigant training program was completed .

PPE FOR ENTRY DURING THE ENTRY-RESTRICTED PERIOD: PPE for handler entry that is permitted by the WPS is listed in the Hazards to Humans and Domestic Animals section of this labeling .

Protection for Handlers The following activities are prohibited from being performed by anyone other than persons who have been appropriately trained and equipped as handlers in accordance with the re-quirements in WPS (40 CFR Part 170):

• Monitoring fumigant air concentrations;

• Cleaning up fumigant spills (this does not include emergency personnel not associated with the fumigation application);

• Handling or disposing of fumigant containers;

• Cleaning, handling, adjusting, or repairing the parts of fumigation equipment that may contain fumigant residues; and

• Performing any handling tasks as defined by the WPS (40 CFR 170).

The following activities are prohibited from being performed in the application block from the start of the application until the entry restricted period ends and in the buffer zone during the buffer zone period by anyone other than persons who have been appropriately trained and equipped as handlers in accordance with the requirements in WPS (40 CFR Part 170).

Prohibited activities (except for trained and equipped handlers) include:

• Participating in the application as supervisors, loaders, drivers, tractor co-pilots, shovelers, cross ditchers, or as other direct application participants;

• Installing, repairing, operating, or removing irrigation equipment;

• Performing scouting, crop advising, or monitoring tasks;

• Installing, perforating (cutting, punching, slicing, poking), or removing tarps; and

• Repairing or monitoring tarps until 14 days after application is complete if tarps are not per-forated and removed during those 14 days. NOTE: see Tarp Perforation and/or Removal section on this labeling for requirements about when tarps are allowed to be perforated.

Handlers do not include local, state, or federal officials performing inspection, sampling, or other similar official duties .

Supervision of handlers:

For all applications from the start of the application until the application is complete, a certi-fied applicator must be at the application block in the line of sight of the application and must directly supervise all persons performing handling activities .

For handling activities that take place after the application is complete until the entry re-stricted period expires, the certified applicator is not required to be on-site, but must have communicated in a manner that can be understood by the site owner and handlers respon-sible for carrying out those activities the information necessary to comply with the label and procedures described in the FMP (e .g ., emergency response plans and procedures) .

IMPORTANT: this requirement does not override the requirements in the Worker Protection Standard for Agricultural Pesticides for information exchange between operators of agricul-tural establishments and commercial pesticide applicators .

The certified applicator must provide Fumigant Safe Handling Information to each handler or confirm that within the past 12 months, each handler has received Fumigant Safe Handling Information in a manner that he/she can understand . Fumigant Safe Handling Information will be provided where this product is purchased or at http://www.epa.gov/fumiganttraining .

Exclusion of Non Handlers from Application Block and Buffer Zone:

The certified applicator supervising the application and the owner of the establishment where the application is taking place must make sure that all persons who are not trained and PPE-equipped and who are not performing one of the handling tasks as stated in this labeling are:

• excluded from the application block during the entry restricted period, and

• excluded from the buffer zone during the buffer zone period (see buffer zone exemption for transit on roadways in Buffer Zone Requirements section).

Local, state, or federal officials performing inspection, sampling, or other similar official du-ties are not excluded from the application block or the buffer zone by this labeling . The certified applicator supervising the application and the owner of the establishment where the application is taking place are not authorized to, or responsible for, excluding those officials from the application block or the buffer zone .

Providing, cleaning, and maintaining PPE:

The employer of any handler (as stated in this label) must make sure that all handlers are provided and correctly wear the required PPE. The PPE must be cleaned and maintained as required by the Worker Protection Standard for Agricultural Pesticides.

Air-purifying Respirator Availability:

At least one handler must have the appropriate air-purifying respirator and cartridges avail-able, and they must be fit-tested, trained, and medically examined .

The employer of any handler must confirm that an air-purifying respirator and appropriate cartridges of the type specified in the PPE section of this labeling are immediately avail-able for each handler who will wear one . At least one handler must have the appropriate air-purifying respirator and cartridges available (see Respirator Fit Testing, Medical Qualifi-cation, and Training section for additional requirements). Exception: After the application is complete, air-purifying respirators do not need to be made available for handlers performing fumigant site monitoring tasks outside of the buffer zone .

Respirator Fit Testing, Medical Qualification, and Training Using a program that conforms to OSHA’s requirements (see 29 CFR Part 1910.134), em-ployers must verify that any handler that uses a respirator is:

• Fit-tested and fit-checked

• Trained, and

• Examined by a qualified medical practitioner to ensure physical ability to safely wear the style of respirator to be worn. A qualified medical practitioner is a physician or other licensed health care professional who will evaluate the ability of a worker to wear a respirator . The initial evaluation consists of a questionnaire that asks about medical conditions (such as a heart condition) that would be problematic for respirator use . If concerns are identified, then additional evaluations, such as a physical exam, might be necessary . The initial evaluation must be done before respirator use begins. Handlers must be reexamined by a qualified medical practitioner if their health status or respirator style or use-conditions change .

Upon request by local/state/federal/tribal enforcement personnel, employers must provide documentation demonstrating how they have complied with these requirements.

Respiratory Protection and Stop Work Triggers: The following procedures must be fol-lowed to determine whether an air-purifying respirator is required or if operations must cease for any person performing a handling task (except for fumigant site monitoring outside of the buffer zone) as stated in this label .

• If at any time any handler experiences sensory irritation (tearing, burning of the eyes or nose), then either:

An air-purifying respirator must be worn by all handlers who remain in the application block or surrounding buffer zone, or Operations must cease and handlers not wearing an air-purifying respirator must leave the application block and surrounding buffer zone .

• Handlers can remove air-purifying respirators or resume operations if two consecutive breathing-zone samples taken at the handling site at least 15 minutes apart show that levels of MITC have decreased to less than 600 ppb (0.6 ppm), provided that handlers do not experience sensory irritation . During the collection of air samples, an air-purifying respirator must be worn by the handler taking the air samples . Samples must be taken at the location where the irritation was first experienced or where samples were greater or equal to 6000 ppb (6 ppm).

• When using monitoring devices to monitor air concentration levels, a direct read detection device, such as an electronic device or a colorimetric device (e .g ., Draeger, Sensydine) must be used. The devices must have sensitivity of at least 600 ppb (0.6 ppm) for MITC.

Persons using direct read detection devices must follow the manufacturer’s directions .

• When breathing zone samples are required, they must be taken outside respiratory protec-tion equipment and within a 10 inch radius of the handler's nose and mouth.

• When air-purifying respirators are worn, air monitoring samples must be collected at least every 2 hours in the breathing zone of a handler performing a representative handling task .

• If at any time: (1) a handler experiences sensory irritation when wearing an air-purifying respirator, or (2) a MITC air sample is greater than or equal to 6,000 ppb (6 ppm) then all handler activities must cease and handlers must be removed from the application block and surrounding buffer zone .

• Handlers can resume work activities without air-purifying respirators if two consecutive breathing-zone samples taken at the handling site at least 15 minutes apart show levels of MITC have decreased to less than 600 ppb (0.6 ppm), provided that handlers do not experience sensory irritation . During the collection of air samples an air-purifying respira-tor must be worn by the handler taking the air samples . Samples must be taken at the location where the irritation was first experienced or where samples were greater or equal to 6000 ppb (6 ppm) .

• Handlers can resume work activities if all of the following conditions exist provided that the appropriate air-purifying respirator is worn or where samples were greater or equal to 6000 ppb (6 ppm):

two consecutive breathing zone samples for MITC taken at the handling site at least 15 minutes apart must be less than 6,000 ppb (6 ppm), handlers do not experience sensory irritation while wearing an air-purifying respirator, and filter cartridges have been changed .

During the collection of air samples an air-purifying respirator must be worn by the handler taking the air samples . Samples must be taken at the location where the ir-ritation was first experienced .

Tarp Perforation and/or Removal IMPORTANT: Persons perforating, repairing, removing, and/or monitoring tarps are defined, within certain time limitations, as handlers (see Handlers section) and must be provided the PPE and other protections for handlers as required on this labeling and in the Worker Protection Standard for Agricultural Pesticides .

• Tarps must not be perforated until a minimum of 5 days (120 hours) have elapsed after the application is complete, unless a weather condition exists which necessitates early perfora-tion or removal (see Early Tarp Removal for Broadcast Applications Only and Early Tarp Perforation during Flood Prevention Activities for Bedded Applications Only requirements).

• If tarps are perforated within 14 days after the application is complete, tarp removal must not begin until at least 2 hours after tarp perforation is complete .

• If tarps are perforated but not removed within 14 days after the application is complete, planting or transplanting must not begin until at least 48 hours after the tarp perforation is complete .

• If tarps are not perforated or removed within 14 days after the application is complete, planting or transplanting may take place while the tarps are being perforated .

• Each tarp panel used for broadcast fumigation must be perforated.

• Tarps may be perforated manually ONLY for the following situations:

At the beginning of each row when a coulter blade (or other device which performs similarly) is used on a motorized vehicle such as an ATV.

In fields that are 1 acre or less .

During flood prevention activities .

• In all other instances tarps must be perforated (cut, punched, poked, or sliced) only by mechanical methods .

• Tarp perforation for broadcast fumigations must be completed before noon.

• For broadcast fumigations tarps must not be perforated if rainfall is expected within 12 hours .

• Early Tarp Removal for Broadcast Applications Only:

Tarps may be removed before the required 5 days (120 hours) if adverse weather conditions have compromised the integrity of the tarp, provided that the compromised tarp poses a safety hazard . Adverse weather includes high wind, hail, or storms that blow tarps off the field and create a hazard, e .g ., tarps blowing into power lines and onto roads . A compromised tarp is a tarp that due to an adverse weather condition is no longer performing its intended function and is creating a hazard .

• Early Tarp Perforation during Flood Prevention Activities for Bedded Applications Only:

Tarp perforation is allowed before the 5 days (120 hours) have elapsed .

Tarps must be immediately retucked and packed after soil removal .

Mandatory Good Agricultural Practices (GAPs) The following GAPs must be followed during all fumigant applications .

Weather Conditions

• To determine if unfavorable weather conditions exist or are predicted (see Identifying

Unfavorable Weather Conditions) and whether application should proceed, the National Weather Service weather forecast must be checked by the certified applicator supervising the application:

on the day of, but prior to the start of the application, and on a daily basis during applications if the time period from the start of the application until the application is complete is greater than 24 hours .

• Do not apply if an air-stagnation advisory issued by the National Weather Service is in ef-fect for the area in which the application is planned, during the application, or the 48 hours after the application is complete .

• Do not apply if light wind conditions (< 2 mph) are forecast to persist for more than 18 consecutive hours from the time the application starts until 48 hours after the application is complete .

• Detailed National Weather Service forecasts for local weather conditions, wind speed, and air stagnation advisories may be obtained on-line at: http://www.nws.noaa.gov, on NOAA weather radio, or by contacting your local National Weather Service Forecasting Office .

Identifying Unfavorable Weather Conditions

• Unfavorable weather conditions block upward movement of air, which results in trapping fumigant vapors near the ground . The resulting air mass can move off-site in unpredict-able directions . These conditions typically exist within an hour prior to sunset and continue past sunrise and may persist as late as noontime . Unfavorable conditions are common on nights with limited cloud cover and light to no wind and their presence can be indicated by ground fog or smog and can also be identified by smoke from a ground source that flattens out below a ceiling layer and moves laterally in a concentrated cloud .

Application Restrictions

• Do not use dazomet when the soil temperature is over 90 degrees F, 2 inches deep. The soil temperature must be above 43° F (6° C) and remain at least this high during the entire fumigation period . Application in the field during periods of possible frost must be avoided .

If the soil temperature falls below 43° F (6° C), the gas may sink into deeper soil layers when there is danger of frost which can cause crop injury later if the soil is not aerated deeply enough. The best conditions prevail at soil temperatures of 54-69° F (12-20 ° C).

Do not apply Basamid® G if the soil temperature exceeds 90° F (32° C), 2 inches deep or the ambient air temperature exceeds 103° F (39° C). If the soil temperature is too high, the gases escape too rapidly from the soil, resulting in incomplete fumigation .

• Do not apply within 3-4 feet of growing plants or closer than the drip line of trees and large shrubs . If slopes are treated with this product, take precautions to prevent the chemical from washing downward to growing plants .

• The area intended for treatment should be in seedbed condition with a fine tilth, free of clods . Do not apply dazomet to dry or improperly tilled soil . Repeated cultivation before treating will improve control of perennial weeds . Ditching around the site will prevent weed seeds, nematodes, and fungi from washing into the treated area and contaminating it .

• Do not apply dazomet if ambient air temperature exceeds 103 degrees F.

• Do not store dazomet in an open spreader overnight.

• Do not apply dazomet when wind may cause granules to drift from target area.

• Do not apply dazomet through any type of irrigation equipment.

• Before using dazomet be aware that the three most critical factors for a successful fumiga-tion program are: soil preparation, soil temperature, and soil moisture

• Do not store this product overnight in an open container

• Do not apply Basamid® G to growing crops - it is for use as a soil treatment only .

• Do not apply or mix with any other material.

Water Requirements For optimal effect, the soil to be fumigated must have sufficient moisture for good plant growth (at least 50% available water capacity) for 5-14 days (depending on temperature) before the treatment .

• Prior to application, soil moisture should be at 60-80% field capacity for sand, 50% for loam, and 30-40% for clay soils .

For both water incorporated and mechanically incorporated applications:

Apply Basamid® G to the soil After spreading, apply overhead irrigation to activate Basamid® G and seal the soil surface .

Day 1: Irrigate sufficiently to move the water front 4 to 6 inches into the soil profile. Depend-ing on soil type, structure, and weather conditions, apply 0 .75 to 1 inches of water .

Repeat the application, as necessary, to ensure the soil profile is thoroughly wetted and all granules are activated .

Day 2: Continue irrigation to ensure the surface area retains sealed but not waterlogged.

Typically, half the amount of water applied on Day 1 should be sufficient . Make mul-tiple applications, depending on local conditions, to ensure that no gases escape as they move up through the soil .

Day 3: Continue irrigations to ensure the surface area does not dry out and no cracks ap-pear in the treated area . Typically half the amount of water applied on Day 2 . Make multiple applications, depending on local conditions, to ensure that no gases escape as they move up through the soil .

Day 4: Irrigate with a minimal amount of water to keep the surface sealed and free of cracks.

Typically, half the amount of water applied on Day 3 . Make multiple applications, depending on local conditions .

Maximum Application Rates for Pre-Plant Soil Fumigation

Physical/Mechanical Incorporation Maximum physical incorporated rate for all uses, except for golf course renovation, is 421 lbs of product per treated acre . The maximum rate for golf course fairways, with a physi-cal incorporated application method, is 525 lbs of product per treated acre .

Water Incorporation The maximum rate for water incorporated applications is 262 lbs of product per treated acre .

Greenhouse The maximum rate for all greenhouse applications is 262 lbs . of product per treated acre .

Application with handheld equipment is prohibited.

For greenhouse applications The maximum application block size that can be treated is 50,000 square feet.

During the application keep all doors, vents, and windows to the outside open, and keep all fans or mechanical ventilation systems running within the greenhouse .

For all use sites Application with handheld equipment is prohibited.

Calculating the Broadcast Equivalent Rate To calculate the broadcast equivalent rate for bedded or strip applications the follow-ing information is needed:

• Pounds of product per treated acre

• strip or bed bottom width (inches)

• center-to-center row spacing (inches)

• application block size (acres)

Pounds of product per treated acre is the ratio of total amount of product applied to the size of the total area treated (e .g ., the rate of product applied in the bed) . For bedded or strip applications, the total area treated is the summation of the area (i .e ., length x width) of each treated bed bottom or strip that is located within the application block as shown by the black areas in Figure 1 (e .g ., black areas are 0 .6A or 60% of the area within the application block) .

The area of the space between the beds/strips is not factored in the total area treated .

The application block size is the acreage within the perimeter of the fumigated portion of a field (including furrows, irrigation ditches, roadways) . The perimeter of the application block is the bor-der that connects the outermost edges of total area treated with the fumigant product .

Space Between Beds/Strips is not treated

The “broadcast equivalent rate” must be calculated with the following formula:

broadcast equivalent rate (pounds product/acre) strip or bed bottom width (inches) x pounds product/ treated acre applied in the strip or bed center-to-center row spacing (inches)

Figure 2, Center Row Spacing

- The bed width must be measured from the bottom of bed .

- The center-to-center row spacing must calculate as shown in Figure 2 .

- If there are any ditches, waterways, drive rows and other areas that are not fumigated that are in the application block, multiply the above broadcast equivalent equation by (total area of strips or beds + row spacing) / (application block size) . A sample calculation is provided below .

Sample broadcast equivalent rate calculation

Assumptions:

- Application method is shank bedded

- Bed width is 30 inches (measured at the bottom of bed)

- Center-to-center row spacing is 60 inches

- 200 pounds of product per treated acre is applied in the beds

- Total application block size is 10 acres

- Ditch in the middle of application block is 0.25 acres

- Area of beds + row spacing is 9.75 acres broadcast equivalent rate

APPLICATION INSTRUCTIONS

Preparation Prior to Application

1) Basamid® G can be applied to tilled and non-tilled sites:

a . Tilled Sites: The area intended for treatment should be in seedbed condition with a fine tilth, free of clods . Repeated cultivation before treating will improve control of perennial weeds .

b . Non-Tilled Sites: Remove existing vegetation with a mower or other suitable equip-ment . The vegetation must be cut to the lowest height possible, 1/8-inch or less . Aer-ate and/or verticut to improve water penetration and remove surface debris .

2) In tilled sites, weed seeds or plant material bearing nematodes must be mechanically hoed or plowed into the soil 1-2 weeks before fumigating so that the emerging weeds and nematodes are subject to fumigation.

3) If root-knot nematodes must be controlled, delay application at least 2-3 weeks, until the root-knot infested root residues have begun to decompose and the remaining plant refuse has been tilled into the soil .

4) Do not apply farmyard manure, peat, other organic fertilizers, burnt lime, or lime nitrogen just before, along with, or just after this product.

5) Converting the active ingredient into the gaseous phase depends primarily on soil moisture and temperature (see Application Restrictions and Water Requirements in the GAPs section of this label) .

Methods of Application Apply Basamid® G soil fumigant to properly prepared soils using scoops, shakers, shanks, drop-type fertilizer spreaders, or other suitable equipment. To prevent Basamid® G from sticking to the tires of the application equipment, the surface of the soil should be dry to the touch at the time of application.

Either incorporate the material physically into the soil to the desired depth, or incorporate the mate-rial into the soil with water . If physically incorporated, the soil surface should be sealed as described in the Preparation Prior to Application section . DO NOT store Basamid® G overnight in an uncov-ered container . DO NOT apply Basamid® G when wind may cause granules to drift from target area .

Physical/Mechanical Incorporation for Combined Disease, Nematode, and Weed Control

1) Apply Basamid® G to the soil .

2) After applying, incorporate the granules into the soil as uniformly as possible to the desired depth . This is best accomplished with an L-shaped tine rototiller or spading machine .

3) Following incorporation, seal the soil surface by smoothing or rolling to impede fumigant escape .

4) The treatment is more successful if the incorporation and sealing is followed by thor-oughly wetting the soil, keeping it moist (but not waterlogged) for 72 hours . Alternatively, the soil can be covered with a tarp (e .g . barrier film) (such as polyethylene sheeting or other material) to retain fumigant vapors .

Water Incorporation with Drip Irrigation for Disease and Weed Control

1) Drip irrigation tape or tubing can be applied prior to, or following, the Basamid® G application .

2) Apply Basamid® G to the soil .

3) After applying, cover with tarp (e .g ., plastic mulch) .

4) Activate the Basamid® G using drip irrigation, wetting entirely to the margins of the treat-ed area (such as bed shoulders) .

5) The soil must be kept moist (but not waterlogged) for 72 hours .

Preparation Prior to Planting Before seeding, planting, or transplanting, all the gaseous residues must be gone from the soil . The time between treatment and replanting depends on soil temperature, structure, moisture, and the method of sealing . Do not plant any crop until all fumigant odors have dissipated from the soil and can no longer be detected . Follow the instructions below to al-low any remaining fumigant gases to escape from treated soil before planting . As an added precaution, conduct a cress or lettuce seed germination test as follows:

Safety Germination Test

1) Take soil samples at several places in the treated area . Scrape the surface soil aside and quickly fill a sample into a clear (transparent) glass jar. Do not take soil from be-low the depth of incorporation. Depending on the size of the jar used, either combine samples into a single jar or fill each sample into a separate jar. Fill the jars about halfway and seal them. As a control, fill an additional jar with untreated soil and seal.

2) Sow a small amount of cress (Lipidium sativum) or lettuce (Lactuca sativa) seeds directly onto the soil and seal the jars. Use the same amount of seed in each jar. The soil should be sufficiently moist to assure quick germination.

3) Place the jars in a room with sufficient temperature to allow for speedy germination.

Check for germination after 2 to 3 days. If the seeds have germinated in the jar with the untreated soil but not in the jars with the treated soil, MITC has not yet completely degraded and the treated soil should not be planted . In this case, repeat the germina-tion test after an additional 1-3 days aeration of the treated area. If seeds in all jars germinate normally, and begin to develop normal roots, it is safe to plant the crop .

Soils without Tarps (e.g. Plastic Covers or Mulch) Aerate the soil with hand implements, rakes, or power tillers above the depth of original incorporation before planting . The soil must not be loosened to the original depth of incor-poration as non-fumigated soil may be transported up from lower layers . A new infestation can spread very quickly in decontaminated soil and jeopardize the success of the treat-ment . Avoid planting into treated soil within 1 week after Basamid® G application to allow fumigation to occur and MITC gas to dissipate to levels safe for planting. Table 2 – Planting Recommendations: Soil Temperature and Waiting Period provides recommended wait-ing periods between treatment and planting based on soil temperature . The waiting period can be shortened by repeated hoeing, digging, or other tillage of the soil to speed aeration .

Longer waiting periods may be required in soils with high concentrations of organic matter.

Fall soil treatment is recommended if early spring planting is necessary .

Soils Covered with Tarps Transplants, bulbs, or seeds can be planted directly into a previously treated bed if certain precautions are followed . The plastic sheeting used to tarp a treated area can also function as a mulch and be left in place in the field. For this application, observe the following steps:

1) A waiting period (see Table 3 – Planting Recommendations: Soil Temperature and
