Integration of chemicals and bio-control agents has been the subject of research during recent years. The potential value of bio-pesticides for the control of important plant pathogens requires investigation due to the general requirement for very low pesticide residues in foodstuffs and concerns over the increasing development of resistance to the different classes of chemicals. The aim of the present study was to check the compatibility of different insecticides viz., Decis (deltamethrin 2.8% EC), Ekalux EC 25 (quinalphos 25% EC), Fenval 20% EC (fenvalerate 20% EC), Hilcron 36 SL (monocrotophos 36 SL), Hildan 35 EC (endosulfan 35 EC), Hilmida (imidacloprid 17.8 SL), Marshal 25 E (carbosulfan 25% EC), Rogor 30% EC (dimethoate 30% EC), Rocket 44 EC (profenofos 40%+cypermethrin 4%) with V15 strain of Trichoderma harzianum Rifai. Mycelial growth of V15 strain of Trichoderma harzianum was calculated in the presence of above mentioned insecticides by using Potato Dextrose Broth (PDB) medium and SP3 medium separately. Hilmida (imidacloprid 17.8 SL) was found to be most compatible with V15 strain of Trichoderma harzianum in both the liquid media as it shows nil percentage reduction of mycelium. It was concluded that conclude that Decis (deltamethrin 2.8% EC), Hilcron 36 SL (monocrotophos 36 SL), Hilmida (imidacloprid 17.8 SL) and Rogor 30% EC (dimethoate 30% EC) are compatible insecticides with biocontrol agent (Trichoderma harzianum) while some insecticides viz., Ekalux EC 25 (Quinalphos 25% EC), marshal 25 E (carbosulfan 25% EC) and rocket 44 EC (profenofos 40%+cypermethrin 4%) inhibits the growth of Trichoderma spp.]]>Bhai, R.S. and J.
