In all cases, follow the instructions on the pesticide label. The PNW Insect Management Handbook has no legal status, whereas the pesticide label is a legal document. Read the product label before making any pesticide applications.

Note: Products are listed in alphabetical order and not in order of preference or superiority of pest control.

Note: Chlorpyrifos (Lorsban) is labeled ONLY for perennial grasses grown for seed. It is NOT labeled for annual grasses.
