Bt Crops: Benefits and Concerns
- Bt crops offered environmental benefits by reducing insecticide use.
- However, insect resistance to Bt toxins poses a threat, potentially leading to increased insecticide use again.
Dramatic Insecticide Reduction
- Before Bt crops, cotton farmers sprayed insecticides up to 10 times a season.
- After Bt crops, insecticide use plummeted, and some farmers stopped spraying altogether.
Bt Crops Ease Workload
- Jonathan Evans, a North Carolina farmer, found Bt crops reduced his workload significantly.
- Bt crops allowed for managing more acres with less equipment.
