What to Do About Pesticide Drift (Video)

Reader Contribution by Emily Marquez and Pan Staff Scientist


I’m trying to garden organically, but I’m concerned about pesticide drift. How can I tell whether drift is affecting my property, and what can I do about it?

Pesticides do indeed “drift” and damage plants growing in neighboring areas. If the drifting chemical is an herbicide, then you may notice damage to plants. Loss of
foliage, yellowing vegetation at the wrong time of year, or damage occurring only on certain portions of plant leaves may indicate herbicide drift. Other symptoms of injury may include twisted leaves or downward-cupped leaves. However, drift from other types of pesticides may be difficult to detect. In some states, the department of agriculture will test crops for drift damage. Laboratory analysis can be costly, and it will not reveal who’s responsible for the drift.

Pesticide drift also poses a threat to human health. Symptoms of acute exposure range from headaches to difficulty breathing to skin irritation. Exposure to some pesticides is also associated with long-term negative effects.

If you know you’ve been exposed to pesticide drift and are concerned about your health, you may want to seek medical advice. Document the problem, if possible. Then, file a report with both the National Pesticide Information Center and the lead pesticide or public health agency in your state, and press for an immediate investigation, including sampling for residues.

Pesticide drift is illegal in most states, but proving who broke the law can be difficult. To inquire about what pesticide was sprayed — and by whom — contact your state pesticide regulatory agency. Join or start a community group (formal or informal) to address pesticide drift.

Scientists with the Pesticide Action Network (PAN) have been working with communities across the country to implement an easy-to-use, scientifically rigorous tool called the “Drift Catcher” for monitoring airborne pesticides. Contact PAN to learn more about this community air-monitoring device. The Drift Catcher is modeled after technology used by the California Air Resources Board to monitor the air for pesticides. Farmers, teachers and homeowners have used the Drift Catcher to document the presence of pesticides near their farms, schools and homes, and have then wielded the data to demand policy changes.

PAN is part of an international network working to replace the use of hazardous pesticides with ecologically sound and socially just alternatives. For more about drift and how to detect it, go to the Pesticide Action Network’s website.
