GE "Superweeds" and "Superpests"
Genetically engineering crops to be herbicide-resistant or to produce their own pesticide presents dangerous problems. Pests and weeds will inevitably emerge that are pesticide or herbicide-resistant, which means that stronger, more toxic chemicals will be needed to get rid of the pests. We are already seeing the emergence of the first "superweeds" as GE herbicide-resistant crops such as rapeseed (canola) spread their herbicide-resistance traits to related weeds such as wild mustard plants. Lab and field tests also indicate that common plant pests such as cotton boll worms, living under constant pressure from GE crops, will soon evolve into "superpests" completely immune to Bt sprays and other environmentally sustainable biopesticides. This will present a serious danger for organic and sustainable farmers whose biological pest management practices will be unable to cope with increasing numbers of superpests and superweeds.
