50%虫螨腈·丁醚脲悬浮剂112.5克/公顷、187.5克/公顷、262.5克/公顷药后1天平均防效分别为43.77%、59.41%、65.15%,药效较差,药效缓慢,击倒速度不快;药后3天的平均防效分别为69.05%、84.73%、88.93%;药后7天的平均防效分别为69.53%、89.79%、93.71%,可看出其防治效果三天达到较高正常水平,且7天后防效仍较高,因此,持效期长达7天以上。采用DMRT法对试验结果统计分析,供试药剂中、高剂量处理间无差异,但二者与低剂量处理之间,均存在显著性差异,区组间无显著性差异。
The average control effect of 50% carbamitri? Diafenthiridan 112.5 g / ha, 187.5 g / ha and 262.5 g / ha on the 1st day was 43.77%, 59.41% and 65.15%, respectively. The average antifunctions in the three days after treatment were 69.05%, 84.73% and 88.93%, respectively. The average antifunctions in the 7 days after treatment were 69.53%, 89.79% and 93.71% Three days to reach a higher normal level, and 7 days after the control effect is still high, therefore, persist for up to 7 days. The statistical analysis of the test results by the DMRT method showed no difference between the medium and the high-dose treatment, but there was a significant difference between the two treatments and the low-dose treatment, with no significant difference between the groups.
