Compatibility of biopesticides with insecticides in ipm

Abstract

Application of compatible products plays a vital role in IPM. Efficient usage of insecticides compatible with biopesticides has been successfully demonstrated. Knowing compatibility is very important to recommend insecticides and biopesticides for use in an ecosystem, without chemical or physical exchanges leading to reduction in efficacy or increase in phytotoxicity. Entomopathogenic fungi (EPF) like Beauveria bassiana, Metarhizium anisopliae and Lecanicillium lecanii were found to be compatible with insecticides like spinosad, fipronil, acephate, many OPs (quinalphos, profenophos, triazophos) and neonicotinoids (acetamiprid, imidacloprid, thiamethoxam), whereas entomopathogenic bacteria (EPB) like Bt were compatible with insecticides like emamectin benzoate, flubendiamide, indoxacarb, many OPs (quinalphos, profenophos), and Pseudomonas fluorescens was found compatible with spinosad, diafenthiuron, many OPs (chlorpyriphos, monocrotophos, triazophos) and neonicotinoids (acetamiprid, imidacloprid). Entomopathogenic viruses (EPV) were compatible with insecticides like fenvalerate, OPs, spinosad and systemic insecticides of narrow range, while entomopathogenic nematodes (EPN) were compatible with insecticides like OPs, deltamethrin, lamdacyhalothrin, chlorantraniliprole and neonicotinoids, and botanicals were compatible with wide range of insecticides like synthetic pyrethroids and OPs depending on dose, time and temperature during application.
