RECENT STUDIES ON THE CHEMICAL CONTROL OF RICE PESTS

Abstract

Tne relative effectiveness of 37 insecticides applied as seedling root dip (SD), 29 insecticides applied as foliar sprays after transplanting (DAT) and 19 insecticides applied into standing field water (SW) was evaluated against rice brown planthopper, stem borer. leaf folder and whorl maggot. Mephosfolan SD was effective against all the four pests tested. while azinphos-methyl, endosulfan, leptophos, monocrotophos and phosphamidon as SD were next best, showing effectiveness against two of them. As foliar sprays, ethyl parathion was effective against three pests while chlorpyriphos, chlorphenamidine. MIPC, methamidophos and phosalone were next best being effective against two of the pests tested. As standing water applications, BPMC and carbofuran followed by AC. 92,100, chlorfenvinphos, carbaryl + lindane. diazinon, andrin, mephosfolan and quinalpnos were effective against three or two of the pests tested. On the whole, mephosfolan, followed by carboturan, azinphos-methyl, diazinon and quinalphos were promising with broad spectrum effectiveness against the rice pest complex.
