Union Slough Chemical Treatment Statement of Work Vendor will provide and apply chemical to invasive species on Waterfowl Production Areas (WPAs) and National Wildlife Refuges (NWRs) in Iowa. WPAs and NWRs consist of wetland and grassland areas throughout 35 counties of Iowa. Terrain is rough and uneven so chemical will need to be applied by ATVs/UTVs or off-road vehicles. Areas needing treatment generally consist of individual plants or small patches of invasive species. Chemical will be applied by individual plant or by patch to reduce the amount of chemical applied. A broadcast chemical treatment of the entire WPA or NWR will not be allowed. Maps will be provided for each area needing treatment and an on-site visit is required. Chemical application will typically occur between July 15th and October 15th each year. Specific dates will be set by the station based on the invasive species needing treatment. The three most common chemical applications are listed below with the best management practices. Additional chemicals may be needed based on the invasive species, but only chemicals and rates approved by the stations Pesticide Use Proposal will be allowed.

Vendor will follow label instructions and follow the best management practices during application as outlined in the approved Pesticide Use Proposals:

Milestone:

* Vendor must hold a valid Iowa pesticide applicator license and all persons applying pesticide must be certified commercial pesticide applicators within the State of Iowa.

* Application will occur at wind speeds less than 10 mph (but not inversion conditions).

* Application equipment will be calibrated prior to application.

* Pesticide application buffers will be used around sensitive areas (neighboring crops that may be injured).

* Vendor will use ground application equipment only.

* Vendor will use nozzles that create uniform, large droplet sizes to minimize drift.

* Do not apply pesticides to slopes >5% if significant rainfall is predicted within 24 hours.

*Do not apply directly to surface water.

Method/Escort Tank Mix:

* Vendor must hold a valid Iowa pesticide applicator license and all persons applying pesticide must be certified commercial pesticide applicators within the State of Iowa.

* Application will occur at wind speeds less than 10 mph (but not inversion conditions).

* Application equipment will be calibrated prior to application.

* Pesticide application buffers will be used around sensitive areas (neighboring crops that may be injured).

* Vendor will use ground application equipment only.

* Vendor will use nozzles that create uniform, large droplet sizes to minimize drift.

* Do not apply pesticides to slopes >5% if significant rainfall is predicted within 24 hours.

*Do not apply directly to surface water.

Garlon 3A or Element 3A:

* Vendor must hold a valid Iowa pesticide applicator license and all persons applying pesticide must be certified commercial pesticide applicators within the State of Iowa.

* Application will occur at wind speeds less than 10 mph (but not inversion conditions).

* Application equipment will be calibrated prior to application.

* Pesticide application buffers will be used around sensitive areas (neighboring crops that may be injured).

* Vendor will use ground application equipment only.

* Vendor will use nozzles that create uniform, large droplet sizes to minimize drift.

* Be aware of potential ground water contamination in porous soils (this chemical is labeled for application to surface water).

* Do not apply pesticides to slopes >5% if significant rainfall is predicted within 24 hours.
