application to control tent caterpillars, it must be applied before the caterpillars cocoon or it will be ineffective. Any method used should be site-specific and not used wholesale over a wide area. Apply the pesticide according to label directions. Under no conditions shall pesticides be applied in quantities that exceed manufacturer’s instructions. Mix the pesticides and the application equipment in an area where accidental spills will not enter surface or groundwater, and will not contaminate the soil. Store pesticides in enclosed areas or in covered impervious containment. Ensure that pesticide contaminated stormwater or spills/leaks of pesticides are not discharged to storm drains. Do not hose down paved areas to a storm drain or conveyance ditch. Store and maintain appropriate spill cleanup materials in a location known to all near the storage area. Cleanup any spilled pesticides and ensure that the pesticide contaminated waste materials are kept in designated covered and contained areas. The pesticide application equipment must be capable of immediate shutoff in the event of an emergency. Do not spray pesticides within 100 feet of open waters including wetlands; ponds; and streams, sloughs, and any drainage ditch or channel that leads to open water, except when approved by Ecology or by . All sensitive areas including wells, creeks, and wetlands must be flagged prior to spraying. As required by or by Ecology, complete public posting of the area to be sprayed prior to the application. applications should only be conducted during weather conditions as specified in the label direction and applicable local and state regulations. Do not apply during rain or immediately before expected rain. Suggested BMPs for the Use of Pesticides Consider alternatives to the use of pesticides such as covering or harvesting substitute vegetative growth, and manual weed control/moss removal. Consider the use of soil amendments, such as compost, that are known to control some common diseases in plants, such as Pythium root rot, ashy stem blight, and parasitic nematodes. The
