摘要:用松毛虫质型多角体病毒油剂超低容量喷雾防治2~4龄松茸毒蛾幼虫,20d死亡率为47.7%~60.6%,存活幼虫感染率69.8%~84.6%,总防治效果85.1%~94.7%。相同病毒用量下的防治效果与常量喷雾相当或略好。合适的用量为1500×108~3000×108PIB/hm2,合适的喷幅为6~10m。
ULV of DCPV OL was used against Dasychira axutha larva between its 2nd and 4th instars.The result showed it had a high control effect.The mortality was 47.7%-60.6% within 20 days while over 69.8%-84.6% of the surviving larvae were infected with DCPV and the total control effect was 85.1%-94.7%.The control effects of ULV spray and normal volume spray were almost the same with the same volume of virus.The right volume of DCPV in ULV spray was 1 500×10~8-3 000×10~8 PIB/hm^2,the effective spray range was between 6 and 10 m.
