【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。更多还原

【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.更多还原
