WEED RESISTANCE MANAGEMENT

This product is a Group 4 herbicide. Any weed population may contain or develop plants naturally resistant to this product and other Group 4 herbicides. The resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field.

Appropriate resistance-management strategies should be followed. To delay herbicide resistance take one or more of the following steps:

• Rotate this product or other Group 4 herbicides within a growing season sequence or among growing seasons with different herbicide groups that control the same weeds in a field.

• Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to which active ingredient is currently less prone to resistance.

• Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information related to herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural (e.g., higher crop seedling rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological (weed-competitive crops or varieties) and other management practices.

• Fields should be scouted prior to application to identify the weed species present and their growth stage to determine if the intended application will be effective. Fields should be scouted after application to verify that the treatment was effective and to monitor weed populations for early signs of resistance development. Indicators of possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage equipment when moving between fields, and planting clean seed.

• If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch to another management strategy or herbicide with a different mode of action, if available.

• Contact your local sales representative, crop advisor, or extension agent to find out if suspected resistant weeds to this MOA have been found in your region. If resistant biotypes of target weeds have been reported, use the application rates of this product specified for your local conditions. Tank mix products so that there are multiple effective mechanisms of action.

• Contact your local sales representative, agricultural dealer, consultant, local extension specialist, applicator, crop advisor, and/or appropriate state agricultural extension service representative for additional pesticide resistance-management and/or integrated weed-management recommendations for specific crops and weed biotypes.

• Report any incidence of non-performance of this product against a particular weed species to your local sales representative or agricultural dealer.

• For further information or to report non-performance or suspected resistance, contact Nufarm at 1-800-345-3330

BEST MANAGEMENT PRACTICES

mechanical cultivation, biological management practices, and crop rotation.

• Fields with difficult to control weeds should be rotated to crops that allow the use of herbicides with alternative mechanisms of action or different management practices.

• Do not allow weed escapes to produce seeds, roots or tubers. Manage weed seeds at harvest and post-harvest to prevent a buildup of the weed seed-bank.

consider all of the weeds present.

control program. Do not use more than two applications of this or any other herbicide with the same mechanism of action within a single growing season unless mixed with an herbicide with another mechanism of action with an overlapping spectrum for the difficult-to-control weeds.

• If resistance is suspected, treat weed escapes with an herbicide with a different MOA or use non-chemical methods to remove escapes.

AVOIDING INJUROUS SPRAY DRIFT

Applications should only be made when there is little or no hazard from spray drift. Small quantities of spray, which may not be visible, may seriously injure susceptible plants. Do not spray when wind is blowing toward susceptible crops or ornamental plants that are near enough to be injured. It is suggested that a continuous smoke column at or near the spray site or a smoke generator on the spray equipment be used to detect air movement, lapse conditions, or temperature inversions (stable air). If the smoke layers or indicates a potential of hazardous spray drift, do not spray.

Aerial Application – When making aerial applications on rights-of-way or other areas near susceptible crops, apply through a Microfoil(1) or Thru-Valve(1) boom, or use an agriculturally approved drift control agent. Other drift reducing systems or thickened sprays prepared by using high viscosity inverting systems may be used if they are made as drift-free as are mixtures containing agriculturally approved thickening agents or applications made with the Microfoil or Thru-Valve boom. Keep spray pressures low enough to provide coarse spray droplets.

Spray boom should be no longer than 3/4 of the rotor length. Spray only when the wind velocity is low (follow state regulations). Avoid application during air inversions. If a spray thickening agent is use, follow all use recommendations and precautions on the product label.

SPRAY DRIFT MANAGEMENT

Avoiding spray drift at the application site is the responsibility of the applicator. The interaction of many equipment and weather-related factors determine the potential for spray drift. The applicator and the grower are responsible for considering all these factors when making decisions.

The following drift management requirements must be followed to avoid off-target drift movement from aerial applications:

1. The distance of the outer most operating nozzles on the boom must not exceed 3/4 the length of the rotor.

2. Nozzles must always point backward parallel with the air stream and never be pointed downward more than 45 degrees.

Where states have more stringent regulations, they must be observed.

Aerial Drift Reduction Advisory Information on Droplet Size: The most effective way to reduce drift potential is to apply large droplets. The best drift management strategy is to apply the largest droplets that provide sufficient coverage and control. Applying larger droplets reduces drift potential, but will not prevent drift if applications are made improperly, or under unfavorable environmental conditions (see Wind, Temperature and Humidity, and Temperature Inversions).

Controlling Droplet Size:

larger droplets. When higher flow rates are needed, use higher flow rate nozzles instead of increasing pressure.

orientations and is the recommended practice. Significant deflection from horizontal will reduce droplet size and increase drift potential.

• Nozzle Type - Use a nozzle type that is designed for the intended application. With most nozzle types, narrower spray angles produce larger droplets. Consider using low-drift nozzles. Solid stream nozzles oriented straight back produce the largest droplets and the lowest drift.

Boom Length: For some use patterns, reducing the effective boom length to less than 3/4 of the wingspan or rotor length may further reduce drift without reducing swath width.

Application Height: Applications should not be made at a height greater than 10 feet above the top of the largest plants unless a greater height is required for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind.

Swath Adjustment: When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up and downwind edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath adjustment distance should increase, with increasing drift potential (higher wind, smaller drops, etc.).

Wind: Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, including droplet size and equipment type, determine drift potential at any given speed. Application should be avoided below 2 mph due to variable wind direction and high inversion potential. Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns and how they affect spray drift.

Temperature and Humidity: When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. Droplet evaporation is most severe when conditions are both hot and dry.

Temperature Inversions: Applications should not occur during a local, low level temperature inversion because drift potential is high.

Temperature inversions restrict vertical air mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable directions due to the light variable winds common during inversions. Temperature inversions are characterized by increasing temperatures with altitude and are common on nights with limited cloud cover and light to no wind. They begin to form as the sun sets and often continue into the morning. Their presence can be indicated by ground fog; however, if fog is not present, inversions can also be identified by the movement of the smoke from a ground source or an aircraft smoke generator. Smoke that layers and moves laterally in a concentrated cloud (under low wind conditions) indicates an inversion, while smoke that moves upward and rapidly dissipates indicates good vertical air mixing.

Sensitive Areas: The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is minimal (e.g., when wind is blowing away from the sensitive areas).

Ground Application – To aid in reducing spray drift, this product should be applied in thickened (high viscosity) spray mixtures using an agriculturally approved drift control additive, high viscosity invert system, or equivalent as directed by the manufacturer. With ground equipment, spray drift can be reduced by keeping the spray boom as low as possible; by applying 20 gallons or more of spray per acre;

by keeping the operating spray pressures at the lower end of the manufacturer’s listed pressures for the specific nozzle type used (low pressure nozzles are available from spray equipment manufacturers); and by spraying when wind velocity is low (follow state regulations).

In hand-gun applications, select the minimum spray pressure that will provide adequate plant coverage (without forming a mist). Do not apply with nozzles that produce a fine droplet spray.

High Volume Leaf-Stem Treatment: To minimize spray drift, do not use pressure exceeding 50 PSI as the spray nozzle and keep sprays no higher than brush tops. An agriculturally approved thickening agent may be used to reduce spray drift.

APPLICATION METHODS

Use this product at rates of 3/4 to 9 lb. ae of triclopyr (1/4 to 3 gallons of this product) per acre to control broadleaf weeds and woody plants. In all cases, use the amount specified in enough water to give uniform and complete coverage of the plants to be controlled. Use only water suitable for spraying. Use an agriculturally labeled non-ionic surfactant for all foliar applications. When using surfactants, follow the use directions and precautions listed on the surfactant manufacturer’s label. Use the higher concentrations of surfactant in the spray mixture when applying lower spray volumes per acre. The order of addition to the spray tank is water, spray thickening agent (if used), additional herbicide (if used), and this product. Surfactant should be added to the spray tank last or as recommended on the product label.

If combined with emulsifiable concentrate herbicides, moderate continuous adequate agitation is required.

For best results, apply when woody plants and weeds are actively growing. When hard to control species such as ash, blackgum, choke cherry, elm, maples, oaks, pines, or winged elm are prevalent and during applications made in late summer when the plants are mature and during drought conditions, use the higher rates of this product alone or in combination with picloram.

When using this product in combination with 2,4-D 3.8 lb. amine, or low volatile ester herbicides, use higher rates of this product for satisfactory brush control.

Use the higher dosage rates when brush approaches an average of 15 feet in height or when the brush covers more than 60% of the area to be treated. If lower rates are used on hard to control species, resprouting may occur the year following the treatment.

On sites where easy to control brush species dominate, rates less than those listed may be effective. Consult state or local extension personnel for such information.

When tank mixing, refer to the individual product labels for precautionary statements, restrictions, recommended rates, approved uses, and a list of weeds and woody plants controlled.

Woody Plant Control: Use 6 to 9 lb. ae of triclopyr (2 to 3 gallons of this product) in enough water to make 20 to 100 gallons of total spray per acre or 1 1/2 to 3 lb. ae of triclopyr (1/2 to 1 gallon of this product) may be combined with 2,4-D amine, like Weedar® 64, or low volatile esters or picloram in sufficient water to make 20 to 100 gallons of total spray per acre.

FOLIAGE (NON-GRAZED AND NON-GRAZED RIGHTS OF WAY) TREATMENTS,

CUT SURFACE TREATMENTS, STUMP TREATMENTS

Foliage Treatment (Non-Grazed Rights-of-Way)

Non-Grazed Areas: Use 6 to 9 lb. ae of triclopyr (2 to 3 gallons of this product) or 3 to 4 1/2 lb. ae of triclopyr (1 to 1 1/2 gallons of this product) in a tank mix combination with 2,4-D amine, or low volatile esters or picloram, and apply in a total spray volume of 10 to 30 gallons per acre. Use the higher rates and volumes when plants are dense or under drought conditions.

Interspersed areas in non-grazed rights-of-ways that may be subject to grazing may be spot treated if the treated area comprises no more than 10% of the total grazable area.

Cut Surface Treatments Individual plant treatments such as basal bark and cut surface applications may be used on any site listed on this label at a maximum use rate of 2.67 gallons of this product (8 lb. ae of triclopyr) per acre. These types of applications are made directly to ungrazed parts of plants and are not restricted by the grazing maximum rate of 2/3 gallon of this product (2 lb. ae of triclopyr) per acre.

To control unwanted trees of hardwood species such as elm, maple, oak and conifers in labeled sites, apply this product either undiluted or diluted in a 1 to 1 ratio with water as directed below.

Tree Injector Method: Apply by injecting 1/2 milliliter undiluted product or 1 milliliter of the diluted solution through the bark at intervals of 3 to 4 inches between centers of the injector wound. These injections should completely surround the tree at any convenient height.

Note: No Worker Protection Standard worker entry restrictions or worker notification requirements apply when this product is injected directly into plants.

Hack and Squirt Method: Make cuts around the tree trunk with a hatchet or similar equipment so that the cuts overlap slightly and make a continuous circle around the trunk. Spray 1/2 milliliter of undiluted product or 1 milliliter of the diluted solution into the pocket created between the bark and the inner stem/trunk by each cut.

With Frill or Girdle Method: Make a single girdle through the bark completely around the tree at a convenient height. The frill should allow for the herbicide to remain next to the inner stem and absorb into the plant. Wet the cut surface with undiluted or diluted solution.

The above methods may be used successfully at any season except during periods of heavy sap flow of certain species such as maples.

Stump Treatment Spray or paint the cut surfaces of freshly cut stumps and stubs with undiluted product. The cambium area next to the bark is the most vital area to wet.

FOREST MANAGEMENT APPLICATIONS

For broadcast applications, use a spray volume which will provide thorough plant coverage. Recommended spray volumes are usually 10 to 30 gallons per acre by air or 10 to 100 gallons per acre by ground. To improve spray coverage of spray volumes less than 50 gallons per acre, add an agriculturally approved nonionic surfactant. See the Application Methods section. Application systems should be used to prevent hazardous drift to off-target sites. Nozzles or additives that produce larger droplets of spray may require higher spray volumes to provide brush control. See the Application Methods section.

Forest Site Preparation (Not for Conifer Release) Use up to 6 lb. ae of triclopyr (2 gallons of this product) and apply in a total spray volume of 10 to 30 gallons per acre or this product at 3 to 4 1/2 lb. ae of triclopyr (1 to 1 1/2 gallons of this product) may be used with picloram low volatile ester in a tank mix combination in a total spray volume of 10 to 30 gallons per acre. Use a nonionic agricultural surfactant for all foliar applications. See the Application Methods section.

Note: Conifers planted sooner than one month after treatment with this product at less than 4 lb. ae of triclopyr (1 1/3 gallons of this product) per acre or sooner than two months after treatment at 4 to 6 lb. ae of triclopyr (1 1/3 to 2 gallons of this product) per acre may be injured. When tank mixtures of herbicides are used for forest site preparation, labels for all products in the mixture must be consulted, and the longest recommended waiting period before planting observed.

Directed Spray Applications for Conifer Release To release conifers from competing hardwoods such as red maple, sugar maple, striped maple, sweetgum, red and white oaks, ash, hickory, alder, birch, aspen, and pin cherry, mix 3 to 6 lb. ae of triclopyr (1 to 2 gallons of this product) in enough water to make 100 gallons of spray mixture.

To improve spray coverage, add an agriculturally labeled nonionic surfactant. See the Application Methods section. The spray mixture should be directed onto foliage of competitive hardwoods using knapsack or backpack sprayers with flat fan nozzles or equivalent any time after hardwoods have reached full leaf size, but before autumn coloration. The majority of treated hardwoods should be less than 6 feet in height to ensure adequate spray coverage. Care should be taken to direct spray away from contact with conifer foliage, particularly foliage of desirable pines.

Note: Spray may cause temporary damage and growth suppression where contact with conifers occurs; however, injured conifers should recover and grow normally. Over-the-top spray applications can kill pines.

Broadcast Application for Conifer Release in the Northeastern United States To release spruce, fir, red pine, and white pine from competing hardwoods such as red maple, sugar maple, striped maple, alder, birch (white, yellow, and grey), aspen, ash, pin cherry, and Rubus spp. and perennial and annual broadleaf weeds, use this product at rates of 1 1/2 to 3 lb. ae of triclopyr (2 to 4 quarts of this product) per acre alone or with 2,4-D amine, or 2,4-D ester to provide no more than 4 lb.

ae per acre from both products. Apply in late summer or early fall after conifers have formed their overwintering buds and hardwoods are in full leaf prior to autumn coloration.

Broadcast Applications for Douglas Fir Release in the Pacific Northwest and California To release Douglas fir from competing vegetation such as broadleaf weeds, alder, blackberry or Scotch broom, apply this product at 1 to 1 1/2 lb.

ae of triclopyr (1 1/3 to 2 quarts of this product) per acre alone or in combination with 4 lb. per acre of atrazine. Mix all sprays in a water carrier with a nonionic surfactant. See the SPRAY ADDITIVES section of APPLICATION DIRECTIONS. Apply in early spring after hardwoods begin growth and before Douglas fir bud break (“early foliar” hardwood stage) or after Douglas fir seasonal growth has “hardened off” (winter bud set) in late summer, but while hardwoods are still actively growing. When treating after Douglas fir bud set, apply prior to onset of autumn coloration in hardwood foliage.

Note: Treatments applied during active Douglas fir shoot growth (after spring bud break and prior to bud set), may cause injury to Douglas fir trees.

CHRISTMAS TREE PLANTATIONS

This product is used to for the control of woody plants and annual and perennial broadleaf weeds in established Christmas tree plantations.

For best results, make applications when woody plants and weeds are actively growing. This product does not control weeds which have not emerged at the time of application. If lower rates are used on hard to control woody species, resprouting may occur the year following treatment. Brush over 8 feet tall is difficult to treat efficiently using hand equipment such as backpack or knapsack sprayers. When treating large brush or trees or hard to control species such as ash, black gum, choke cherry, elm, hazel, madrone, maples, oaks or sweetgum, and for applications made during drought conditions or in late summer when the leaves are mature, use the higher rate of this product or use cut surface application methods. For foliar applications, apply in enough water to give uniform and complete coverage of the plants to be controlled. Applications made under drought conditions may provide less than desirable results.

Use Precautions:

• Newly seeded turf (alleyways, etc.) should be mowed two or three times before any treatment with this product.

Use Restrictions:

• Do not use on newly seeded grass until well established as indicated by vigorous growth and development of secondary root system and tillering.

Spray Preparation Refer to the Tank Mixes section for order of addition to the spray tank. Continue moderate agitation while mixing and spraying. Use a nonionic agricultural surfactant for all applications. See the Application Methods section for surfactant recommendations. When using surfactants, follow use directions and precautions listed on the manufacturer’s label. Use the higher recommended concentrations of surfactant in the spray mixture when applying lower spray volumes per acre. Note: If tank mixing with AquaNeat® Herbicide, mix this product with at least 75% of the total spray volume desired to ensure that this product is well mixed before adding AquaNeat to avoid incompatibility.

Application Apply in late summer or early autumn after terminal growth of Christmas trees has hardened of, but before leaf drop of target plants. Apply at a rate of 3/4 to 1 3/4 lb. ae of triclopyr (2 to 5 pints of this product) per acre as a foliar spray directed toward the base of Christmas trees.

Use sufficient spray volume to provide uniform coverage of target plants (20 to 100 gallons per acre). Do not apply with 2,4-D. Application rates of this product directed for Christmas trees will only suppress some well-established woody plants that are greater than 2 to 3 years old (see table below). Broadcast sprays may also be applied in bands between the rows of planted trees. Use spray equipment that will assure uniform coverage of the desired spray volume.

Spray solution from this product can cause needle and branch injury to Christmas trees. To minimize injury to Christmas trees, direct sprays so as to minimize contact with foliage. Blue spruce, white spruce, balsam fir and Frasier fir are less susceptible to injury than white pine and Douglas fir.
