Kharbade, S.B. | Tamboli, N.D. | Chormule, A.J.
The higher level of incidence was noticed from 6ᵗʰ MW to 18ᵗʰ MW. The peak of 39.35 mites/3 leaves was recorded in 18ᵗʰ MW. Bio-efficacy of acaro-insecticides bifenazate 240 SC, fenazaquin 10 EC, thiamethoxam 25 WG, chlorfenapyr 10 SC, hexythiazox 10 EC, clothianidin 50 WG, dicofol 18.5 EC (standard check) and abamectin 1.9 EC (treated check) along with botanicals viz., neem oil 5000 ppm and horti-impact against Polyphagotarsonemus latus on capsicum in rabi season. In comparison with untreated check all the treatments were found to be promising in suppressing the mite's population on capsicum. Treated check, abamectin 1.9 EC was observed to be most promising by recording lowest cumulative mean mite population of 3.21 mites/3 leaves and was on par with chlorfenapyr 10 SC (3.58 mites/3 leaves), fenazaquin 10 EC (3.91 mites/3 leaves) and bifenazate 240 SC (4.13 mites/3 leaves) followed by dicofol 18.5 EC (4.56 mites/3 leaves). Next effective treatments were thiamethoxam 25 WG, clothianidin 50 WG and hexythiazox 10 EC which recorded 8.00, 8.77 and 9.35 mites/3 leaves, respectively and were noticed at par with each other followed by horti-impact (15.38 mites/3 leaves) and neem oil 5000 ppm (16.59 mites/3 leaves).
