Why does the label matter so much?
Pesticide labels are legal documents. They list what the product is for, how it must be used, protective gear, where it cannot be used, waiting periods and storage and disposal instructions. Using a product in a way the label does not allow is against the law and can harm people, animals, pollinators and water.
Read the label before you buy the product, before you mix it and again before you apply it. If you have any question about whether a product is right for your situation, ask your county extension office before purchase.
Keep the label or a photo of it so you can tell a veterinarian or poison control exactly what was used, and keep a note of the time and the amount you believe was involved. Do not rely on memory later.
Should I use a pesticide at all?
Often the best first step is to identify the problem. Insects, disease and weeds that look alike can have very different solutions, and many problems can be handled by changes in planting, sanitation, spacing, timing and tolerance. Your extension office can help you identify the problem and discuss options.
If you decide a pesticide is needed, choose a product that lists your specific crop or site and pest on its label, and buy only what you will use soon. Smaller quantities reduce storage risks.
How should pesticides be stored?
Keep pesticides in a locked, dry, ventilated place away from food, feed, seed, fertilizer, fuel, pets and children. Keep them off the floor and away from heat sources, direct sun and freezing temperatures that can damage containers. Make sure the space is not near wells, floodplains or drains.
Keep products in their original, labeled containers with the lids tightly closed. Store liquids below powders so a leak will not wet dry products. A plastic tray or tub underneath catches small spills.
Cover the unknowns in the same way. Pesticides bought years ago, repackaged products and containers with torn labels are the ones people end up guessing about, and guessing is where harm begins.
- Locked and ventilated storage
- Original containers with intact labels
- Separate from food, feed, fuel and fertilizer
- Away from wells, drains and water
How do I handle products when mixing and applying?
Mix and load outdoors or in a ventilated area on a surface that will not drain into water. Wear the gear named on the label, measure carefully and mix only what you need. Never eat, drink or smoke while handling pesticides.
Check the weather before applying. Wind can carry product onto neighbors, ponds, gardens and bee habitat. Keep children, pets and animals away from the area during application and for the time the label specifies.
What should I do about spills and exposure?
Stop, keep people and animals back and read the label for spill guidance. Use absorbent material to contain a spill and dispose of it as the label or your local waste office directs. Do not hose a spill into a drain or ditch.
If a person is exposed, follow the first aid steps on the label and call poison control or emergency services right away, with the container nearby. For animals, call your veterinarian or an animal poison service.
How do I clean up and dispose of leftovers?
Clean sprayers and equipment where rinse water will not contaminate soil or water, and follow label directions. Never wash equipment in a stream, a pond or near a well. Launder work clothes separately from family laundry.
Do not pour leftovers on the ground or down the drain. Ask your county solid waste office, state department of agriculture or extension office about collection programs for unwanted pesticides and empty containers. Rules differ by state and county.
Pregnant people, children and anyone with health conditions should be kept away from mixing and applying altogether. Ask your doctor if you are unsure whether you should be handling these products.
What records and routines help?
Keep a simple log of what you buy, when you apply it, where and why. It helps you avoid repeat mistakes, follow waiting periods and share information with a doctor or vet if needed. Some operations are required to keep records, so ask your state department of agriculture whether your situation falls under a rule.
Check your storage area every season, remove old or unlabeled containers and replace damaged ones. Teach everyone who helps on the farm the basic rules, and keep the area locked.
Key takeaways
- The label is the law, and it covers use, gear, storage and disposal.
- Identify the problem first and ask your extension office about options.
- Lock pesticides away from food, feed, children and pets in original containers.
- Mix and apply outdoors, mind the wind and keep people and animals away.
- Ask your state agriculture department and extension office about disposal programs and recordkeeping rules.
