摘要
5%丙硫克百威GR不同剂量防治稻水象甲的田间试验表明:5%丙硫克百威GR对稻水象甲具有良好的防治效果,其速效性和持效性好于5%辛·唑磷GR,但未达到显著差异水平。5%丙硫克百威GR1.125、1.500、1.875、2.250kga.i./hm2药后10d的平均防效分别为69.53%、81.00%、86.70%、89.35%,4个处理间差异不显著;卵和幼虫减退率高于对照药剂5%辛·唑磷GR。建议田间使用5%丙硫克百威GR剂量为1.500~2.250kga.i./hm2。
Benfuracarb 5% GR has relatively high effects on Lissorhoptrus oryzophilus and is higher than phoximtriazophos 5% GR with no significant difference among all treatments. Control effects of benfuracarb 5% GR are 69.53, 81.00, 86.70 and 89.35% at 1.125, 1.500, 1.875, 2.250 kg a.i./ha after 10 days of treatment in field experiment. The results of field plot test demonstrate that the amount of L. oryzophilus eggs and larvaels reduced was higher than that of phoximtriazophos 5% GR. The suggested application sage is 1.500-2.250 kg a.i./ha.
