Intensification of the vegetable cultivation has created tremendous pest problems; which led to high pesticide use, often with no reduction in pests attack, making vegetable production more dependent on pesticides. Use of toxic and broad spectrum pesticides threatens the sustainability of vegetable production mainly due to development of resistance against pests, eliminating natural enemies, environmental disharmony.
