摘要： 为明确杀虫单对早稻螟害敏感性的恢复情况,探明当前杀虫单及其配方对螟害的控制效果,本研究在早粳早稻螟害初害期开展了杀虫单及其与喹硫磷、二嗪磷的复配药剂对早稻螟害的策略性无人机飞防试验(田间初害期飞防1次,间隔10 d作第2次飞防)。结果表明,使用80%杀虫单可溶性粉剂(SP)100 g处理后0 d(即策略性飞防第2次施药当天)的校正保苗效果为87.64%,药后10 d上升至90.57%,药后25 d保持在83.49%,优于20%杀虫单水剂(AS)400 mL+25%喹硫磷乳油(EC)200 mL、80%杀虫单SP 100 g+25%喹硫磷EC 200 mL、80%杀虫单SP 100 g+50%二嗪磷150 mL等有机磷混配处理和对照药剂25%乙基多杀菌素水分散粒剂(WG)15 g处理的防治效果。由此可见,80%杀虫单SP 100 g单剂配方对螟害的敏感性总体优于等剂量AS配方及其与喹硫磷、二嗪磷的混配配方,对控害保苗保穗有良好效果。

Abstract:

To clarify the recovery of susceptibility to borer pest and to investigate the current effect of monosultap and its formulations in controlling borer pest damage, a strategic UAV prevention trial (field early damage phase UAV prevention once, followed by a second UAV prevention 10 days later) was conducted using monosultap and its mixtures with quinalphos and diazinon at the early damage stage of early japonica rice borer pest infestation. The results showed that the 100 g 80% monosultap SP treatment had a corrected seedling protection effect of 87.64% on 0 d (the day of the strategic second application), which increased to 90.57% on 10 d and was maintained at 80.45% on 25 d, better than the effect of 20% monosultap AS 400 mL + 25% quinalphos EC 200 mL treatment,80% monosultap SP 100 g + 25% quinalphos EC 200 mL, 80% monosultap SP 100 g + 50% diazinon 150 mL, which were organophosphate mixtures. The effect was also better than the control treatment of 25% spinetoram WG 15 g. It can be seen that the single formulation of 80% monosultap SP 100 g is more sensitive to borer pest, overall superior to the equivalent dosage of AS formulations, and better than its mixtures with auinalphos and diazinon, showing good effects on controlling damage, protecting seedlings, and preserving panicles.
