Abstract
The effect of the application of acaropathogenic fungi viz., Beauveria bassiana, Nomuraea anisopliae, Lecanicillium lecanii, Hirsutella thompsonii and biopesticides viz., azadirachtin 1500 ppm, azadirachtin 3000 ppm, azadirachtin 10000 ppm and Fortified Neem oil were tested with synthetic acaricides like Propargite and Fenazaquin against two-spotted spider mite (Tetranychus urticae). The result of evaluation of acaropathogenic fungi revealed that low mite population of 5.68 nos/2cm2 was observed in Fenazaquin 10 EC @ 1.5ml/l applied plot with 69.78% reduction in mite population followed by Propargite and Nomuraea anisopliae treated plots and the result of evaluation of botanicals revealed that the application of Azadiractin 10000 ppm @ 2 ml/l resulted in low mite population of 6.75 nos /2 cm2 with 64.11% reduction over control. Therefore, the present investigation outlines the efficacy of plant extracts and acaropathogenic fungi as bio pesticide to display toxicity against two-spotted spider mite on brinjal increasing in yield and avoid environmental pollution and consumer health hazards.
