Abstract

Eighteen granular insecticides, broad-casted by hand at the rate of 1.1 kg/ha at 15, 40 and 70 days after transplanting, were evaluated for the control of rice stemborers in the paddy field. Prethylene 3G.,Padan 10G., Birlane 5C., Furadan 3G..Terracur P5G., Cytrolane10G..,Thiodan 5G., BHC 6G. and Bayrusil 3G were found to be effective against rice stemborers. Among these Prethylene 3G. was most outstanding.In relation to fish toxicity, Thiodan 5G. and Furadan 3G, were observed to be more hazardous than Prethylene 3G., Cytrolane 10G. and Birlane 5G.
