Obtain and follow current label directions for all agrichemicals. If you have further questions, contact your extension agent http://extension.oregonstate.edu/
Always consult and strictly follow a current label when using pesticides. Most Agrichemical Companies listed under Related Sites in the PIE typically supply on-line versions of current labels for their particular products. If you don't know the manufacturer, go to CDMS--Agrichemical Database or C&P Press Greenbook or similar sites and type the product name in the slots provided to identify the manufacturer and/or pull up a full-text label.
Use pesticides safely!! Wear protective clothing and safety devices as recommended on the label. Bathe or shower after each use. Know your legal responsibility as a pesticide applicator. You may be liable for injury or damage resulting from pesticide use. Don't become a neighborhood nuisance by contributing to herbicide drift onto sensitive crops.
*Since the handbooks are usually updated only periodically, suggestions may be technically and legally outdated. Furthermore, many recommendations may apply only to the Pacific Northwest.
