Herbicide Application

What This Service Involves

Our crews deliver calibrated herbicide programs for cities, districts, and agencies that lack in-house licensed applicator capacity. Every application is performed by a WSDA-licensed commercial applicator who selects products by target species, site sensitivity, and label restrictions. We maintain the application records required under WAC 16-228, including product, rate, wind conditions, and location, so your agency can respond to any public records request. Spot and broadcast methods are matched to each site to minimize off-target drift near playgrounds, transit stops, and open water.

Benefits

Provides certified applicator coverage without adding licensed staff; produces defensible records for public disclosure and audits; reduces chemical volume through calibrated equipment; limits drift risk around high-use civic spaces

Our Process

1) Confirm target vegetation and review label and site-use restrictions; 2) Calibrate equipment and verify weather is within label wind and temperature limits; 3) Apply with the appropriate spot or broadcast method and post required notices; 4) File WAC 16-228 application records and schedule any needed re-treatment

What Affects the Cost

Acreage and whether spot or broadcast coverage is specified; product selection driven by target species and site sensitivity; posting and public-notification requirements; equipment calibration and mobilization for dispersed sites; weather windows that constrain scheduling

Best Time of Year

Applications are scheduled around dry, low-wind windows, which in Western Washington are most reliable from late spring through early fall.
