Abstract

Field trials of more than 10 insecticides or their mixed preparations were made in order to screen the effective preparations for controlling the rice caseworm( Cnaphalocrocis medinalis ). The results showed that 35% zhongjuanqing wettable powder(mixed preparation with chlorpyrifos and acephate) applied at dose of 80 g/667 m\+2 and 35% dusawei emulsifiable concentrates(mixed preparation with chlorpyrifos and dichlorvos) at 80 mL/667m\+2 were able to control this insect effectively.
