what are biopesticides????
Biopesticides are those biological agents that are used for control of weeds, insects and pathogens.
There are three types of biopesticides- microbial pesticides (such as bacteria, viruses, fungi, etc), biochemical pesticides (such as insect sex pheromones) and plant incorporated protectants (such as GM crops).
Biopesticides, a contraction of 'biological pesticides', include several types of pest management intervention: through predatory, parasitic, or chemical relationships. The term has been associated historically with biological control - and by implication - the manipulation of living organisms.Biochemical pesticides are naturally occurring substances that control pests.
