不同浓度氟环·咯·甲苯拌种对小麦萌发及光腥黑穗病防效的影响

Effects of Wheat Seeds Dressed by Fluoromethylbenzene with Different Concentrations on Germination Rate and Protection against Tilletia foetida Lindr

氟环·咯·甲苯在田间实际生产中被广泛应用于防治小麦光腥黑穗病。目前该农药防治小麦散黑穗病在中国获得了登记,但是对小麦光腥黑穗病的防治尚未报道。因此,本实验将用五种不同浓度的氟环·咯·甲苯拌种小麦后检测其萌发率及发病率。从而筛选出拌种剂量为5%的最优防治途径,另外,该试验还表明过度使用该农药拌种会抑制小麦种子萌发。

Fluoromethylbenzene is widely used in the field production to prevent and control common bunt of wheat. At present, the pesticide prevention and treatment of wheat loose smut in China has been registered, but the treatment on common bunt of wheat has not been reported. Therefore, the experiment used five different concentrations of fluoromethylbenzene mixed wheat after the statistics of its germination rate, and then detect the incidence of wheat. Thus, the optimal dose of the mixing for the prevention and treatment on common bunt of wheat was 5% recommended dose of fluoromethylbenzene. At the same time, the experimental data also showed that excessive use of the pesticide mixing will inhibit wheat seed germination.
