Online published on 21 July, 2020. Abstract This study evaluates the insecticidal activity of few biorationals (methanolic extracts of plants/plant parts), for their toxicity against Lipaphis erysimi (Kalt.), one of the most serious pests of mustard, especially late sown crop. The results reveal that thiamethoxam @ 0.33 g/l was superior than the castor seed and bhang leaf extracts. Increase in seed yield was observed with castor seed extract (1494.44 kg/ha) followed by Cannabis sativa extract (1258.33 kg/ha), which was comparable to thiamethoxam (1216.66 kg/ha). Top Keywords Mustard, Lipaphis erysimi, castor seed, cannabis leaf, thiamethoxam, cow urine, yield. Top |
