农药混配剂防治烟蚜的田间药效试验
Field Experiments on Control of Myzus persicae Sulzer with Pesticide Mixture
【摘要】 为筛选出药效较好的杀虫混配剂,同时降低高效农药的使用成本,选取了两种复配剂在不同地区进行了田间小区试验。结果表明:敌百虫+敌杀死的混剂有增效作用,与单剂相比,防效增加了10.23~21.42个百分点,用药量和成本分别减少0.135kg/667m2和1.02元/667m2。方差分析表明,混剂与单剂间防治效果的差异达极显著水平。
【Abstract】 For selecting more effective pesticide mixture and reducing the cost of highly effective pesticides,two pesticide mixtures were selected and evaluated in field plots.The results proved the synergism of dipterex + deltamethrin increased the control effect by 10.23-21.42 percentage points,dosage and cost reduced by 0.135kg/667m~2 and 1.02yuan/667m~2 respectively,comparing with single pesticide.The variance analysis showed that the control effect difference between single and mixed pesticides was(extremely) significant.
