Abstract:

The experiment was conducted to know the effect of organic, integrated and inorganic management practices on the incidence of insect pests in groundnut and cotton intercropping system during 2015-2016 to 2016-2017 at Institute of Organic Farming, University of Agricultural Sciences, Dharwad, Karnataka, India. In groundnut, the per cent defoliation due to Spodoptera litura ranged from 11.5 to 16.75 in different farming systems. However, the incidence was more in organic as compared to integrated and inorganic management practices. Similarly, the studies made in cotton revealed that the per cent boll damage due to Helicoverpa armigera varied from 8.19 to 12.75 in different farming systems. The incidence of bollworms was less in integrated and RPP and found on par with each other and differed significantly with organic farming. The similar trend was observed with aphids and leafhoppers where as the incidence was less than ETL. The natural enemies�?? viz., coccinellids and Chrysoperla were observed more in organic as compared to other farming systems.
