20%氟虫双酰胺WDG等药剂防治二化螟药效试验

20%氟虫双酰胺WDG等药剂防治二化螟药效试验(毕业论文8120字)
摘  要 ：为筛选防治水稻二化螟的高效农药，探索其在水稻上的推广前景，进行了几种药剂防治水稻二化螟田间试验。结果表明，20%氟虫双酰胺仍是防治水稻二化螟的首选药剂，667ｍ2用30～40mL在卵孵化高峰期使用，能有效控制二化螟的为害，保苗效果在92%以上。三唑磷类农药在二化螟的防治上，效果明显下降，尤其是三代二化螟，应引起重视。

Control Effect of 20% Flubendiamide WDG and other pesticides against Chilo suppressalis Walker
    Abstract:For screening high-effective pesticide of controling Chilo suppressalis Walker on rice and explore the prospects of promotion in rice, then people conducted field trials of several pesticides controling Chilo suppressalis Walker on rice.Tests showed that 20% Flubendiamide is still the first choice to control the Chilo suppressalis Walker on rice, 667m2 with 30~40mL at the peak of hatching using can effectively control the damage of Chilo suppressalis Walker, seedling protection effect is at 92% or higher. The effect of Pesticide Triazophos at the prevention of Chilo suppressalis Walker is significantly decreased, especially at the three generations of Chilo suppressalis Walker, attention should be paid.
