Abstract
Eleven selected insecticides were evaluated for their compatibility to Trichoderma based on in vitro sensitivity of T. harzianum and T. virens. Observations on radial growth indicated that, chlorpyriphos and quinalphos were incompatible with Trichoderma spp showing 100 per cent inhibition of radial growth at field concentration. While dimethoate and endosulfan were least compatible showing more than 70 per cent inhibition of radial growth. Indoxacarb, carbofuran, fipronil were moderately compatible with radial growth inhibition in the range of 3-11per cent. Spinosad, emamectin benzoate, thiamethoxam and indoxacarb were found highly compatible with zero inhibition of radial growth of test Trichoderma isolates.
