Mcqs On Biopesticides
Biopesticides are pesticides of biological origin. These include natural products and organisms used for pest control, such as bacteria, fungi, virus, chemicals derived from plants (e.g. neem oil) and genetically modified crops (e.g. Bt cotton). Unlike traditional pesticides, biopesticides do not alter plant physiology or provide nutrients; instead, they act on pests directly.
