Compatibility of Biocontrol Agent Trichoderma viride with Various Pesticides

Abstract

Compatibility of Trichoderma viride with 25 pesticides was evaluated in vitro. Among six seed-treatment chemicals tested, T. viride showed a high compatibility with the insecticide Imidacloprid (7.6cm mycelial growth), followed by Mancozeb (6.3cm) and Tebuconazole (3.7cm). Contact fungicides, viz., Pencycuron and Propineb were found to be fully compatible with T. viride. Among the 10 herbicides also tested, the fungus was highly compatible with Imazathafir (9.0cm) followed by 2,4-D Sodium salt (8.9cm) and Oxyfluoforen (6.5cm) while being totally incompatible with systemic fungicides like Carbendazim, Hexaconazole, Tebuconazole and Propiconazole.
