摘要
以广两优676为供试水稻品种进行25%噻嗪酮可湿性粉剂防治稻飞虱田间药效试验,结果表明：25%噻嗪酮可湿性粉剂对稻飞虱具有显著的防治效果,且具有良好的速效性和持效性,对水稻和非靶标生物安全。当25%噻嗪酮可湿性粉剂有效成分用量为112.5 g/hm2时,药后1、3、7 d对稻飞虱的防治效果分别为90.57%,95.03%和96.08%。生产上适宜的有效成分用量为93.75-112.5 g/hm2。
The control effect of 25% Buprofezin Wettable Powder on rice planthopper was investigated using Guang Liang You 676 as test materials.The results showed that 25% Buprofezin Wettable Powder could effectively control rice planthopper at 1 、3、7 days after spraying with long lasting validity period and high available effect,and was safety to non-target inserts.The control effect on rice planthopper was 90.57%,95.03% 和96.08%,respectively,when the dosage of the active compounds of 25% Buprofezin Wettable Powder was 112.5 g/hm2.The optimal dosages range of active compounds were from 93.75 g/hm2 to 112.5 g/hm2 in agricultural practice.
