Field experiments were conducted to evaluate the efficacy of Biorationals against red spider mites on
okra and brinjal at different spray schedule. Altogether eight treatments, i.e. Azadirachtin 10,000 ppm
@1ml/l, Lecanicillium lecanii @2g/l, Neem soap @10g/l, Organic salt 30 WS @4 ml/l, Organic salt 30
WS @ 5ml/l, Spinosad 45 SC @0.2 ml/l, Dimethoate 30 EC @1.6 ml/l and one control (no spray) were
selected for the experiment. Cumulative mean efficacy on population reduction after 3, 7 and 15 days
after spraying indicated that among the different treatments, Organic salt 30 WS @ 5 ml/l was significantly superior and recorded lower mite population (2.59 mites/cm2 leaf on okra and 1.98 mites/cm2 leaf on brinjal) than other treatments. Whereas, the highest number of mites was recorded in neem soap (5.83 mites/cm2
leaf on okra and 4.17 mites/cm2 leaf on brinjal).
