In organicfarming production system, biopesticides like botanicals and mycopathogenicformulation are of greater importance in managing the pest population. Theevaluation of botanicals and mycopathogenic formulation were tested for theirefficacy against okra leafhopper, aphids and whitefly at Organic FarmingResearch Centre, Navile, Shivamogga during 2009. The performance of botanicalsand mycopathogenic formulation against leafhopper revealed that the Neemazol @3.5% recorded 2.43 and 2.60 leafhoppers/3 leaves, Neem oil @ 2% recorded 2.63and 3.50 leafhoppers/3 leaves and NSKE @ 5% recorded 3.53 and 4.00 leafhoppers/ 3 leaves. These three treatments were found superior among botanicals and Beauveriabassiana @ 2.5 g / l recorded 2.5 and 3.6 leafhoppers/3 leaves and was onpar with other mycopathogens at 10 DAS of first and second spray, respectively.Results on aphids and whitefly were recorded as follows: Neemazol @ 3.5%recorded 1.67 and 3.17 aphids/3 leaves and 2.00 and 2.63 whitefly/3 leaves,Neem oil @ 2% recorded 1.93 and 4.33 aphids/3 leaves and 2.17and 3.40whitefly/3 leaves and NSKE @ 5% recorded 2.00 and 6.00 aphids/3 leaves and 3.00and 4.00 whitefly/3 leaves at 10 DAS on the first and the second sprayrespectively and these were found superior among botanicals. Verticilliumlecani @ 2.5 g/l showed 2.53 and 6.67 aphids/3 leaves and 2.80 and 3.53whitefly/3 leaves at 10 DAS on the first and the second spray respectively andwas on par with other mycopathogens.
