几种高效低毒药剂对番茄灰霉病防效对比试验

Control Efficacy of Several High-efficiency and Low-toxicity Fungicides against Tomato Gray Mold

比较研究了5种药剂对番茄灰霉病的防治效果,结果表明,几种药剂均较对照(喷清水)对番茄灰霉病有不同程度的防治效果,其中,特立克可湿性粉剂700倍液和50%凯泽水分散粒剂1 000倍液防效最好,防效均大于85%,增产效果显著,可以在生产中推广应用。

We studied the control efficacy of five high-efficiency and low-toxicity fungicides against tomato gray mold. The results showed that, the five fungicides could control tomato grey mould in different degree, and among them, the two fungicides Telike （trichodermin） wettable powder 700 multiples liquid and 50%Cantus （boscalid） water dispersible granule had highest control efficiency over 85%, in addition, the yield was increased significantly after being applied with the two fungicides, so the two fungicides could be applied in tomato production.
