Brinjal (Solanum melongena L.) is a very important solanaceous crop of tropics and sub-tropics. It is cultivated on large area and commonly grown vegetables across the globe. The brinjal is of much importance in the warm areas. Number of insect pests that attack on crop during the growth period and cause severe losses to this crop. Insect pest caused quantitative and qualitative losses in many brinjal producing areas. In the present study, the efficacy of Beauveria bassiana and Trichoderma harzianum against the insect pests of brinjal was evaluated. Experiment was run out under randomized complete block design (RCBD) with three replications. The data was taken after 12, 24, 48, and 72 hours and then on a weekly basis after application. Results revealed that after 12 hours post treatment combination of B.bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug, (4.65, 4.11, 6.48 and 6.88) after 24 hours post treatment combination of B. bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug (6.71, 6.21, 8.92 and 8.91) After 48 hours post treatment combination of B. bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug (12.62, 16.84, 16.74 and14.32) after 72 hours hours post treatment combination of B. bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug (26.98,36.89,36.69 and 32.67) after 7days post treatment combination of B. bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug (45.87,56.45,54.35 and 45.78) after 14 days post treatment combination of B. bassiana and Trichoderma harzianum was found to be most effective in the mortality of White fly, jassid, aphid and dusky bug, (68.92, 68.93, 68.94 and 62.73) as compared to alone B.bassiana and Trichoderma harzianum caused less mortality than combination of these two Entomopathogenic fungi. Lowest mortality is caused by control treatment.
