Trichoderma pseudokoningii was tested for its compatibility with 11 insecticides, 7 fungicides, 2 herbicides, 1 sticker cum spreader, 4 different inorganic fertilizers in in vitro by poinson food technique. All the pesticides were tested for their compatibility with T. pseudokoningii at two different concentrations i.e., recommended dose (RD) and half of the RD and four different were tested for inorganic fertilizer and organic sticker cum spreader. All the pesticides significantly inhibited the mycelial growth of the fungus T. pseudokoningii except Thiamethonaus 25% WG at 0.125%. Ritha at all the tested doses was found compatible with the biocontrol gaent. Urea and muriate of potash were found compatible with T. pseudokoningii while single super phosphate and calcium ammonium nitrate inhibited its growth. The observed variations in the inhibitory potential could be due to inherent variability of chemical insecticide to biocontrol agents, T. pseudokoningii. CAN inhibited the colony growth of T. pseudokoningii at all the tested concentrations. Present investigations showed varying effects of pesticides, sticker, inorganic fertilizers on the fungi, their actual effects at cellular and field level need to be investigated to understand if the effects are permanent or temporary.
