ABSTRACT
Adverse environmental impact, increasing instances of pest resistance and public concern about food safety are among the major driving forces behind the multifaceted efforts towards the development of biopesticides. These include bioinsecticides for control of insect pests of agriculture and public health concern, biofungicides for the control of plant diseases on agronomic and horticultural crops, and bioherbicides for control of weeds. Several scientific groups searching for biological means for control have addressed a number of significant pests, fungal diseases and weeds. The primary considerations in developing such products have been a) cost effectiveness, b) user friendliness and c) adaptation with existing pest control programmes and d) their consistency and efficacy.
