摘要

Studies on development and promotion of IPM technology in rainfed,Bt and non-Bt cotton(Gossypium hirsutum L.)varieties were carried out for four consecutive years(2001-2004)at the two locations at Nawandi and Loha,Nanded in 6~(th)agro-ecological region of India.Sucking pests were 31.4% and 12.2% more in non-IPM than the IPM fields of Bt and non-Bt cotton,respectively.Similarly,bollworms infestation was 88.1% and 50.3% more in non-IPM than IPM fields of Bt and non-Bt cotton.However,cumulative moth catches per pheromone-trap of all the bollworms were 55.3% and 63.5% more in both the IPM fields.Similarly,the number of natural enemies of the pests per plant was more(3.75-3.57)in IPM fields as compared to non-IPM(0.55-0.94).Cost-benefit ratio analysis of Bt and non-Bt cotton indicated that the production of 928 kg cotton ha~(-1)in IPM required an investment of Rs.2454 ha~(-1)for crop protection as compared to Rs.3161 ha~(-1)in non-IPM plots,for production of 384 kg cotton ha~(-1).A net profit of Rs.18013 ha~(-1)was obtained from IPM plots as against Rs.6679 from non-IPM plots,which led to a costbenefit ratio of 1:4.27 in IPM conditions over non-IPM one.
