ECO-FRIENDLY MANAGEMENT OF TWO SPOTTED SPIDER MITE, TETRANYCHUS URTICAE (KOCH) IN BRINJALV. Baskaran1, E. Sumathi, M. Vignesh and S.V. KrishnamoorthyAbstract The effect of the application of acaropathogenic fungi viz., Beauveria bassiana, Nomuraeaanisopliae, Lecanicilliumlecanii, Hirsutellathompsonii and biopesticides viz., azadirachtin 1500 ppm, azadirachtin 3000 ppm,azadirachtin 10000 ppm and Fortified Neem oil were tested with synthetic acaricides like Propargite andFenazaquin against two-spotted spider mite (Tetranychus urticae). The result of evaluation of acaropathogenicfungi revealed that low mite population of 5.68 nos/2cm2 was observed in Fenazaquin 10 EC @ 1.5ml/lapplied plot with 69.78% reduction in mite population followed by Propargite and Nomuraeaanisopliaetreated plots and the result of evaluation of botanicals revealed that the application of Azadiractin 10000ppm @ 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 biopesticide to display toxicity against two-spotted spider mite on brinjal increasing in yield and avoidenvironmental pollution and consumer health hazards. |
