The present investigation was carried out at Horticultural Instructional Farm, C. P. College of Agriculture, S. D. Agricultural University, Sardarkrushinagar during the summer of 2022. Among seven tested botanicals, azadirachtin at 0.03 per cent (7.01 mites 2 cm-2 leaf area), NSKE at 5 per cent (7.23 mites 2 cm-2 leaf area) and neemastra at 100 per cent (7.74 mites 2 cm-2 leaf area) were found most effective and showed the minimum mite population. Treatments bhramastra at 3 per cent, agnistra at 3 per cent and ardusi leaf extract at 5 per cent were found moderately effective for mites in okra (10.26, 11.13 and 12.32 mites 2 cm-2 leaf area). The treatment noni fruit juice extract at 2 per cent was found less effective in reducing mite population.
