Evaluation of buprofezin 70 DF an insect growth regulator for eco-friendly management of jassid (Amrasca bigutulla bigutulla Ishida) in okra, Abelmoschus esculentus (L.) Moench
Journal Title: Journal of Applied and Natural Science - Year 2015, Vol 7, Issue 2
Abstract
Field experiments were carried out for two seasons in 2012 to evaluate the efficacy of a new formulation of buprofezin (buprofezin 70 DF) against jassid (Amarasca biguttula biguttula Ishida) in okra, Abelmoschus esculentus (L.) Moench. The insecticide was applied at 200 and 150 g a.i./ha at the ETL level of the insect (2 Jassids/leaf) and the performance of the same was compared with imidacloprid 17.8 SL @ 20 g a.i./ha, acephate 75 SP @ 562.5g a.i./ha and an untreated control. Results revealed that both the dosages of buprofezin 70 DF were significantly superior over the untreated control at 5 % level of significance. Buprofezin 70 DF at 200 and 150 g a.i./ha performed better over the other treatments with 88.81 and 85.96 % reduction during first season and 89.60 and 84.73% reduction during second season, respectively. Buprofezin , an insect growth regulator which had less or no hazardous effects on human health and environment and thus it can be incorporated in Integrated Pest Management programme in okra cultivation.
