In Bt cotton era sucking pests are becoming more serious inviting indiscriminate use of pesticides. To control sucking pests effectively, use of stem applicator is cost effective and eco-friendly technology. In this method sucking pest incidence was controlled by the stem application of systemic insecticides monocrotophos or imidacloprid 200 SL with water in 1:4 ratio or 1:20, at 20, 40, 60 days after sowing. Within three days of application the plant, will die. This technique is being practiced for three years in 15 locations of Rangareddy district. Stem application in cotton showed better performance when compared to the farmers practice in the kapas yield in the demo plots. On an average, cotton kapas yield (1425kg/ha) under front line demonstration was higher by 6% percent as compared to farmer's practices. In the second year the Results revealed that on an average, cotton kapas yield (1432kg/ha) under front line demonstration was higher by 6% percent as compared to farmer's practices fallowed by third year where in the findings showed that on an average, cotton kapas yield (2086kg/ha) under front line demonstration was higher by 11% percent as compared to farmer's practices.
