- Abstract
Studies were conducted to determine the toxicity of Roll Up (7.2% G), Furadan (3G), Solomon (300-0-Teq), Belt (48% SC), Karuz (4% GR) and Shark Super (6% G) and relative resistance of rice varieties IRRI-6, KSK-282, DR-83, Basmati-370, Basmati-385 and Super Basmati against rice stem borer and rice leaf folder and their effect on yield ha-1. Roll Up and Shark Super ranked first in their efficacy against rice stem borer; as 0.64% and 0.63% dead hearts and 0.32 and 0.33% white heads were recorded, respectively, and which were significantly (P < 0.05) lower than control. Solomon with 0.73% infestation was the most effective insecticide against rice leaf folder. Rice varieties IRRI-6 and KSK-282 were the most resistant varieties against rice stem borer; as 14.73% and 18.34% dead hearts, and 4.33% and 4.77% white heads were significantly (P < 0.05) lower than the other tested varieties. Similarly IRRI-6, KSK-282 and DR-83 also showed resistance to rice leaf folder. Basmati-385 was the most susceptible variety against rice leaf folder. KSK-282 with 5656 kg ha-1 yield ranked first. Plots treated with shark super resulted in to highest (7014 kg ha-1) yield whereas; plots treated with Karuz resulted into lowest (5984 kg ha-1) yield.
