200 g/L氟唑菌酰羟胺·苯醚甲环唑SC防治花生叶斑病试验

The Efficiency of Pydiflumetofen·Difenoconazole 200 g/L SC Control Peanut Leaf Spot

[目的]探索200 g/L氟唑菌酰羟胺·苯醚甲环唑SC对花生叶斑病防效。[方法]依据花生叶斑病药剂防治田间药效试验准则进行。[结果]200 g/L氟唑菌酰羟胺·苯醚甲环唑SC对花生叶斑病有较高的防效,不同梯度剂量下,防效幅度为59.65%~87.16%,与当地常用对照药剂苯醚甲环唑·丙环唑比较,差异显著。[结论]200g/L氟唑菌酰羟胺·苯醚甲环唑SC可用于花生叶斑病防治,在花生叶斑病发病初期、发展期,吉林省分别为7月上旬和下旬施药2次,适宜用量为75~105 g a.i./hm^(2)。对花生生长、开花、产量未见不良影响。

[Aims]The study aims to explore the control effect of pydiflumetofen·difenoconazole 200 g/L SC on peanut leaf spot.[Methods]The field trials were carried out according to the guidelines for the field efficacy tests of peanut leaf spot.[Results]The results showed that the pydiflumetofen·difenoconazole 200 g/L SC had excellent control effect against peanut leaf spot.The control effect range was 59.65-87.16%under different gradients,which was significantly different from difenoconazole·propiconazole.[Conclusions]At early stage and development stage of peanut leaf spot disease,spraying twice in the first ten days of July and the last ten days of July respectively,and the appropriate dosage for each time was 75-105 g a.i./ha.There was no adverse effect on peanut growth,flowering and yield.
