Cotton is one of the most important fiber and cash crop of India and plays a dominant role in the industrial and agricultural economy of the country. Nearly 65 percent of cotton area is under rained and mainly in the Central and Southern States Cotton crop is highly prone to pests and diseases. In Bt cotton era sucking pests are becoming more serious, inviting indiscriminate use of pesticides. To control sucking pests effectively, stem application technique is cost effective and eco-friendly technology. In this method, sucking pest incidence was controlled by the stem application of systemic insecticides of Monocrotophos 1:4 ratio at 20 days after sowing and Imidacloprid 200 SL with water in 1:20 ration at 40 and 60 days after sowing. Within three days of application the population of sucking pests was reduced. This technique is being demonstrated and documented for two years in 6 locations of Vizianagram district of Andhra Pradesh. Stem application in cotton showed better performance when compared to the farmers practice in terms of no.of bolls and kapas yield in the demo plots. On an average both years cotton kapas yield (2111kg/ha) under Front Line Demonstrations (FLDs) was higher by 19.76% percent as compared to farmer's practices. The results from the study showed that the farmers realized the Rs.17,260 additional net income due to increased cotton kapas yield by 19.76% with reduction of cost of cultivation by Rs.3300, it could be attributed to reduction in manual labour requirement for stem application and also increase in yield attributes and yield.
