Abstract
Field trials were conducted at Anbil Dharmalingam Agricultural College and Research Institute, Tiruchirappalli district, Tamil Nadu, to evaluate the bioefficacy of insecticides and plant-based oils against red spider mite, Tetranychus urticae (Koch) in okra during rabi 2021 and summer 2022. The results revealed that the highest per cent reduction over control of the red spider mite population was recorded in spiromesifen 25 EC @ 0.8 ml/l (73.28% and 67.78%), followed by propargite 57 EC @ 3ml/l (70.82% and 65.51%) in both the seasons, respectively. Among the plant-based oils, karanj oil was most effective against red spider mites, with a per cent reduction over control of 58.7% and 47.98% in rabi, 2021 and summer 2022, respectively. Mahua oil (54.02% and 41.72%) and camphor oil (51.62% and 38.74%) moderately control the red spider mite in okra. Based on moderate to high efficacy and safer natural enemies and environment, spiromesifen 25 EC @ 0.8 ml/l, propargite 57 EC @ 3ml/l and karanj oil 2ml/l would be used as an effective component in the IPM module for okra red spider mite.
