A concurrent and promising effect has been achieved by using microbial inoculants on bio control in recent agricultural practices, an environment friendly as future concern to food safety. The present study aims to evaluate the mycelia growth of Trichoderma viride and Trichoderma harzianum consortium on Potato dextrose agar enriched with different chemical fungicides used to control wilt diseases in many vegetables. It is evident from the data presented that 100 % inhibitory effect was showed in Carbendazim 50 % WP. Highest radial mycelia growth was observed 43.45 mm, 29.89 mm after 72 hr incubation in presence of EDTA-Copper 12% WP and Zineb 75 % WP@ 1 g/L and 0.5 g/L with 3.2 and 33.4 percent inhibition, respectively. The present investigation clearly demonstrates that, the high incompatibility was observed in the treatment of systemic fungicides at all concentrations. Therefore, soil borne plant pathogens can be well managed by combined application of biopesticides with systemic or contact fungicides like EDTA-Cu, Zineb at lower doses. Trichoderma consortia compatible with Copper EDTA and Zineb as GAP in IPM.
