Pesticides and Water Quality

What Is IPM?

Integrated pest management (IPM) is an ecosystem-based strategy that focuses on long-term prevention of pests or their damage through a combination of techniques such as biological control, habitat manipulation, modification of cultural practices, and use of resistant varieties. Pesticides are used only after monitoring indicates they are needed according to established guidelines, and treatments are made with the goal of removing only the target organism. Pest control materials are selected and applied in a manner that minimizes risks to human health, beneficial and nontarget organisms, and the environment.

Snail trap
Use traps, such as this raised board, to trap snails and slugs. Scrape them off daily and destroy.

Hand weeding
Remove weeds by hand or with hand tools instead of with herbicides. Use mulches to suppress growth of new weeds.

Sticky tape
Apply sticky material to tree trunks to exclude crawling insects such as ants.
