For environmental and human health, it is best to avoid storing leftover chemicals. A few easy steps now will help prevent future problems.

Buying -
Keep records of pesticide applications along with corresponding efficacy data to help in planning for the future. Determine what you already have on hand and buy enough chemicals for one season only.
Storing-
Return unused/unwanted/unopened products to the dealer for a refund. Keep an accurate inventory of any chemicals in storage. Keep the volume of chemicals in storage to a minimum, and use older stocks first. Store properly, following all labeled storage directions, so excess chemicals may be used next year.
Using -
Buy ready-to-use products when only a small volume is needed. Buy innovative product formulations that minimize or eliminate the need to handle pesticide products and simplify measurements, such as tablets, dry flowable formulations. Mix only what you need for the application at hand. Calibrate equipment on a regular basis.
Cleaning Up -
Use up excess mix as soon as possible by applying to a labeled crop (do not exceed allowable rates) or using excess to spot spray/respray. Clean equipment in the field and spray out rinsate on labeled crop or site.
