Abstract

The controlling effect of 30% chlorfluazuron chlorfenapyr SC against diamondback moth Plutella xylostella was investigated in the field. The 7th day controlling effects with the concentration of 75, 90 g / hm2were 86.21% and 92.19%, respectively. Its controlling effects was similar to or better than that of 10% chlorfenapyr SC(60 g / hm2) and 5% chlorfluazuron EC(97.5 g / hm2). The results showed that 30% chlorfluazuron chlorfenapyr SC was an ideal insecticide for controlling of diamondback moth. The recommended dosage was 75~90 g/hm2.
