Safety of organic amendments and microbial pesticides to natural enemies in brinjal ecosystem

The studies were carried out to assess the safety of organic amendments in combination with biorationals and microbial pesticides (spinosad 45 SC, emamectin benzoate 5 SG, avermectin 1.9 EC, Btk 5% WP and diafenthiuron 50 WP) on natural enemies associated with insects pests of brinjal. All the organic amendments and biorationals were completely safe to natural enemies (coccinellids, chrysopids & spiders). The tested microbial pesticides including one insect growth regulators did not affect the natural population throughout the crop growth period, but the synthetic insecticide was not safe to the natural enemies in brinjal ecosystem.
