摘要
田间药效试验表明,15%唑虫酰胺EC对抗性小菜蛾具有良好的防治效果,其速效性和持效性均好于目前在生产推广使用的10%虫螨腈SC、15%茚虫威SC和1.8%阿维菌素EC等高效药剂,但未达显著差异水平。制剂用量15%唑虫酰胺EC1150.0、862.5、575.0mL/hm2药后7d的平均防效分别为97.9%、97.8%、92.3%,3个处理间差异不显著。建议田间使用制剂用量为575.0~862.5mL/hm2。
Tolfenpxrad 15% EC has relatively high effects on Plutella xylostella L., was higher than chlorfenapyr 10% SC, indoxacarb 15% SC and avermectin 1.8% EC with no significant difference between all treatments. Control effects of tolfenpxrad 15% EC were 97.9%, 97.8% and 92.3% at 1150.0, 862.5 and 575.0 mL/ha after 7 days of treatment in field experiment, three treatments had no significant difference. The suggested application dosage was 575.0-862.5 mL/ha.
