不同药剂对辣椒疫病的防治效果研究

Control Efficacy of Different Fungicides on Pepper Phytophthora Blight

比较了不同药剂对辣椒疫病的防治效果,结果表明,生防菌对辣椒疫病的防治作用最好,其次是化学药剂甲基硫菌灵,化学药剂丙森锌的防治作用较差。试验结果表明,从北京农业大学植物病理学院引进筛选出的生物复合菌1和生物复合菌2防治辣椒疫病的防效均比化学药剂好。

We compared the control efficacy of different fungicides on pepper phytophthora blight. The results showed thatthe control efficiency of biocontrol bacteria on pepper phytophthora blight was the highest, followed by chemical agentthiophanate methyl, while the chemical agent propineb had worse control effect. The two compound biological bacteriumNo.1 and No.2, selected by Institute of Plant Pathology of Beijing Agricultural University, had better control effects onpepper phytophthora blight than chemical fungicides.
