Abstract: The in-vitro effect of some commonly used fungicides, insecticides and herbicides on the mycelial growth of Trichoderma harzianum PBT 23 were evaluated. Nine fungicides, 6 insecticides and 7 herbicides were tested. A progressive increase in percent inhibition of radial growth in the fungus was observed as the concentrations of the fungicides increased. Among fungicides, Captaf, Thiram, Chlorothalonil and Copper hydroxide were found compatible with the test antagonist up to 100 µg a.i. /ml, while Mancozeb up to 250 µg a.i. /ml, as these did not adversely affect the growth of test antagonist. However, Benomyl, Thiophanate methyl, Bayleton and ipridione were found incompatible with the test antagonist even at 25 µg a.i. /ml. Among insecticides, Monocrotophos, Dichlorvos, Profenophos and Triazophos were found compatible up to 250 µl a.i./ml; while Deltamethrin and Quinalphos up to 100 µl a.i./ml. Seven herbicides, 2, 4-D ethyl ester, Pretilachlor, Aniliofos, Alachlor, Butachlor, Fluchloralin and Pendimethalin were found compatible with the test antagonist even at higher concentration (250 µl a.i. /ml). The present results would be helpful to delineate the possibility of combining T. harzianum PBT 23 as biocontrol agent with agrochemicals under integrated pest management approaches.
