经室内外试验,研究了苯醚甲环唑与克菌丹混配对苹果轮纹病的抑制效果与防治效果。室内生物测定试验结果表明,苯醚甲环唑和克菌丹的有效成分配比为1∶2~8时均表现增效作用,其中有效成分配比1∶4增效作用明显,增效系数达1.73,为最佳配比。田间防治试验结果表明,40%苯醚甲环唑·克菌丹可湿性粉剂1 000、1 500、2 000倍液对苹果轮纹病均表现出良好的防治效果,防效在90.90%以上,且分别减少制剂投入量50.55%、67.04%、75.27%,分别减少农药成本35.37%、56.92%、67.69%。苯醚甲环唑与克菌丹混配制剂可作为防治苹果轮纹病的农药品种。
The indoor and outdoor experiments were carried out to study the inhibitory effect and control effect of difenoconazole mixed with triflumcid on apple stripe disease. Indoor bioassay test results show that the difenoconazole and the amount of the effective component of carbidazole 1: 2 to 8, all show synergistic effect, wherein the active ingredient ratio of 1: 4 synergy, the synergistic coefficient Up to 1.73, for the best ratio. Field control test results showed that 40% difenoconazole 1 000,1 500,2 000 times wettable powder on apple tree rot disease showed good control effect, the control effect of more than 90.90% The dosage of pesticides was decreased by 50.55%, 67.04% and 75.27% respectively, which reduced the cost of pesticides by 35.37%, 56.92% and 67.69% respectively. Difenoconazole azadirachtin mixed with the preparation of formulations can be used as control pesticide varieties of pesticides.
