Abstract
To achieve the objective of effective control over insect pests of rice and enhancing its yield economically, a study was undertaken to evaluate different sprayable and granular insecticides for the control of rice stem borer and leaf folder on the rice variety Basmati-385 by the application of 5 insecticides. Of the granular insecticides, furadan application proved to be the best both in controlling the attack of stem borer and leaf folder as well as better yield per acre, while among sprayable insecticides, nurelle-D proved better for the control of these pests. The furadan application gave the maximum yield (1527 kg acre") with cost benefit ratio of 1:6.67. In sprayables, nurelle-D gave the maximum yield (1263 kg acre") with cost benefit ratio of 1:5.99. The monetary benefit with granulars and sprayables comes to Rs. 8250.66 and Rs. 5874.66 respectively, the difference being significantly high
