不同药剂对葡萄瘿螨的田间防治效果研究
|
摘要
[目的]筛选对葡萄瘿螨防治效果较好的药剂。[方法]通过小区试验研究了4种杀虫剂对葡萄瘿螨的防控效果。[结果]施药后10 d,30%哒螨灵SC 3 000倍稀释液的防效最高,达到86.52%,其次是73%炔螨特EC 3 000倍稀释液和1.8%阿维菌素EC 2 000倍稀释液,防效分别为77.42%和75.55%;施药后20 d,30%哒螨灵SC 3 000倍稀释液、73%炔螨特EC 3 000倍稀释液和1.8%阿维菌素EC2 000倍稀释液的防效有随着时间增加而增加的趋势,防效分别达到90.73%、83.56%和84.28%。[结论]4种杀虫剂对葡萄瘿螨都有一定的控制效果,为新疆葡萄生产选择可靠的替代药剂提供了参考。
[Objective] The aim was to screen out efficient reagents for grape Colomerus vitis. [Method]Control effects of four reagents against grape Colomerus vitis were studied through plot test. [Result]In 10 days,3 000 times diluent of 30% Pyridaben SC had the highest efficiency of86. 52%; the second were 3 000 times diluent of 73% Propargite EC and 2 000 times diluent of 1. 8% Abamectin EC,and their efficiencies were77. 42% and 75. 55%,respectively. In 20 days,the efficiencies of 3 000 times diluent of 30% Pyridaben SC,3 000 times diluent of 73% Propargite EC and 2 000 times diluent of 1. 8% Abamectin EC increased with the increase of time,and reached 90. 73%,83. 56% and 84. 28%,respectively. [Conclusion] The four reagents had certain control effects on grape Colomerus vitis,and the results provided reference for selecting reliable alternative agents for Xinjiang grape production.
