Efficacy of various insecticides and fungicides against thrips and major foliar diseases of garlic

A field study was conducted to evaluate the efficacy of various insecticides and fungicides against thrips and major foliar diseases of garlic (Allium sativum L.) at the Vegetable Research Station, Junagadh Agricultural University, Gujarat, during the Rabi seasons of 2021-22 to 2023-24. Among eight treatments, fipronil 5% SC @ 1 ml/l + sticker 1 ml/l recorded the lowest thrips population (2.09 thrips/plant) after 48 hours of spray and was statistically on par with the tank mix treatment of metiram 55% + pyraclostrobin 5% WG @ 2 g/l + cyantraniliprole 10.26 OD @ 0.9 ml/l + sticker (2.73 thrips/plant). The latter also exhibited the lowest intensity of purple blotch (7.13%) and stemphylium blight (11.44%) diseases and the highest marketable bulb yield (69.30 q/ha) and net return (₹. 2,59,166/ha). The highest ICBR (1:44.79) was observed with the fipronil-based treatment. These findings suggest that the tank mix treatment offers an effective and economical approach for integrated thrips and major foliar disease management in garlic cultivar GJG-5.
