Resurgence of red legged spider mite, Tetranychus ludeni Zacher against synthetic, botanical and fungal origin pesticides on brinjal crop

摘要

The brinjal crop was treated with dicofol 18.5% EC, omite 57% EC, ethion 50% EC, sulphur 80% WP, NSKE, azadiractine, neem oil and mycomite to check the enhancement of the population of red legged spider mite, Tetranychus ludeni Zacher in 2014. The dicofol 18.5% EC, Omite and ethion were showed negative resurgence, —35.26%, —38.11%; —26.60%, —28.25% and —9.64%, —26.69% that acaricides don’t support the enhancement of population and mycomite showed positive resurgence, + 32.82%, + 18.35%, NSKE 5% (+3.34, +4.89), azadirachtin (+5.08, +3.49) and neem oil (+3.75, +4.18) where as sulphur showed very less positive resurgence in the 1~(st) and 2~(nd) spray,+1.01,+1.03, respectively.
