为明确吡唑醚菌酯与苯醚甲环唑混合物对茄链格孢毒力的增效作用,采用菌丝生长速率法和孢子萌发法测定了吡唑醚菌酯、苯醚甲环唑及其不同比例混合物对茄链格孢的毒力,以公式评价其联合毒力,并通过田间试验评价了混合物对马铃薯早疫病的防治效果及其对马铃薯产量的影响。结果表明,吡唑醚菌酯与苯醚甲环唑质量比为
In order to clarify the synergistic effect of the mixture of pyraclostrobin and difenoconazole on Alternaria solani, the effects of pyraclostrobin, difenoconazole and difenoconazole and their derivatives were determined by mycelium growth rate method and spore germination method. The toxicity of the mixture with different proportions to Alternaria solani was evaluated by the formula. The control effect of the mixture on the early blight of potato and its effect on potato yield were evaluated by field experiments. The results showed that the mass ratio of pyraclostrobin to difenoconazole was
