氧化亚铜加过氧乙酸对茶赤星病菌室内生物活性测定和田间药效试验

The Biologic Activitiy and Field Efficacy of the Mixture of Cuprous Oxide and Peracetic Acid against Pseudocercospora theae

通过5种杀菌剂氧化亚铜+过氧乙酸、氧化亚铜单剂、甲基硫菌灵、多抗霉素、多菌灵对茶赤星病分生孢子萌发率测定,证明氧化亚铜+过氧乙酸的抑制率最佳,为81.27%。经田间药效试验结果表明:氧化亚铜加过氧乙酸、波尔多液对茶赤星病的防治效果较好,处理防效分别为92.51%、84.93%。根据各药剂的防效及特点,氧化亚铜加过氧乙酸是防治茶赤星病最理想的药剂。

The test of budding rate on conidum was carried out with the application of 5 fungicides.such as mixture cuprous oxide and peracetic acid, cuprous oxide, thiophanate-methyl, polyoxin and carbendazim The results showed that the control rate of cuprous oxide and peracetic acid was the best,which reached to 81.27%. It could be the ideal fungicide on the control of Pseudocercospora theae
