Guide for calibrating handheld and backpack sprayers

Hand-held and backpack sprayers are inexpensive tools used to apply pesticides on small acreages. Home gardens, yards, small orchards, and Christmas tree plantations are examples of areas that often require pesticide applications to protect them from weeds, insects, and diseases. Effective pest control depends on applying the proper amount of pesticide. This can only be done if the spray equipment is calibrated accurately.

The Virginia Cooperative Extension agency created a handy guide to help calibrate handheld and back sprayers for maximum effectiveness.
