摘要
测定了30％氟啶脲·溴虫腈SC对甘蓝小菜蛾（Plutella xylostella）幼虫的田间防效.结果表明,当30％氟啶脲·溴虫腈SC有效成分量为75、90 g/hm2时,施药7d后对甘蓝小菜蛾的防效分别达到86.21％和92.19％,与2个单剂10％虫螨腈SC有效成分量为60 g/hm2处理和5％氟啶脲EC有效成分量为97.5g/hm2处理的防效相当或更优,表明30％氟啶脲·溴虫腈SC是防治甘蓝小菜蛾较为理想的药剂,建议有效成分量为75～90 g/hm2.
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/hm2 were 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.
