川化-018对白叶枯病具有保护和治疗作用,在体内外对该菌主要是直接起抑菌而不是杀菌作用。叶面内吸作用较好而根系内吸活性极差,仅宜于叶面施药。药效持久性较好,施药后在较短时间内遇雨对药效影响不大。在适当施用浓度下防效显著优于5-氧酚嗪,而接近或稍逊于敌枯双,表明该药是目前防治白叶枯病较理想的一种内吸杀菌剂。
Chuanhua -018 has the protective and therapeutic effects on bacterial leaf blight, which is mainly directly bacteriostatic but not bactericidal to the bacterium in vitro and in vivo. Leaf internal absorption better and root absorption activity very poor, only suitable for leaf application. Persistence is good, after the application of pesticides in a relatively short period of time have little effect on the efficacy of the drug. Under suitable application concentration, the control effect was significantly better than that of 5-oxyphenazine, and close to or less than that of Zuochuangshuang, indicating that this medicine is an ideal systemic bactericide for bacterial leaf blight prevention and control.
