Do not apply pesticides over waterways or canals, and do not apply them to fields being irrigated if drain water runs off field. If laborers are working in crops with heavy foliage, such as cotton, tomatoes, peaches, citrus, etc., that have been treated with highly toxic compounds, be sure the recommended interval between the treatment and entrance into the treated area is observed. These workers should follow the same precautions as given for the applicators in regard to changing clothing, wearing protective clothing, eating or smoking, and bathing. If a worker becomes ill while working under these conditions, call a physician immediately. No pesticide can be applied by either aerial or ground equipment without some drift occurring.
Many pesticides are highly toxic to honey bees and other beneficial insects.
The farmer, the beekeeper, and the pest control industry should cooperate closely to keep losses of beneficial insects to a minimum. When bees are present, the safest time and method of application of pesticides should be employed. Avoid drift of pesticides onto bee colonies or nearby crops and weeds in bloom. Do not contaminate bee drinking water. To protect fish and other wildlife, do not apply pesticides over canals or streams and do not allow drainage from treated fields to enter waterways immediately after application.
