Specific Problems with Pesticide Use Pesticide spray drift endangers the livelihood of organic farmers. When we eliminate an insect, we inherit its job. Because of widespread spraying, indigenous bees are becoming rare and honey more bees are in jeopardy. Organic farming depends on a balance of insect populations some insects predate the pests which devour crops and we encourage them with balanced planting and providing wild refuges. Other beneficial insects and soil organisms are killed by pesticide application, and microecosystems are disrupted.
Pesticide use results in resistance so they have a limited period of usefulness.
Continuous escalation of variety and strength of new pesticides compounds each consequence. A good example of this is the malarial mosquito which has evolved to be resistant even to DDT, and the disease is now more rampant than ever. We may even see malaria returning to Canada. Pesticide residues in food are an ongoing health concern. These days an apple a day can equal a trip to the doctor.
