An experiment was conducted during Kharif-2023-24 at Research cum Instructional Farm of Barrister Thakur Chhedilal College of Agriculture and Research Station Bilaspur, Indira Gandhi Krishi Vishwavidyalaya, Raipur, (C.G.), India to evaluate the bio-efficacy of different pesticide against rice panicle mite (Steneotarsonemus spinki Smiley). Among all the pesticides tested, diafenthiuron 50 WP + propiconazole 25% EC @ 1.5 g + 1.0 ml/litre (3.50 mite/2 cm leaf sheath) were found most effective in controlling the S. spinki which was at par with treatment Profenophos 50% EC + propiconazole 25% EC @ 2.0 ml + 1.0 ml/litre (4.98 mite/2 cm leaf sheath) and fenpyroximate 5% EC @ 1.0 ml/litre (5.89 mite/2 cm leaf sheath) in terms of reduction of rice panicle mite population. The highest grain and straw yield (5157 kg/ha and 6450 kg/ha) were recorded in the treatment diafenthiuron 50 WP + propiconazole 25% EC @ 1.5 g + 1.0 ml/litre. The next best treatment profenophos 50% EC + propiconazole 25% EC @ 2.0 ml + 1.0 ml/litre (4900 kg/ha grain and 6300 kg/ha straw yield) and fenpyroximate 5% EC @ 1.0 ml/litre (4676 kg/ha grain and 6210 kg/ha straw yield). In terms of Cost benefit ratio 1:3.52 the treatment diafenthiuron 50 WP + propiconazole 25% EC @ 1.5 g + 1.0 ml/litre was found most superior over the rest of the treatments.
