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.
