细菌性软腐病是蝴蝶兰生产中重要的病害,常造成严重损失。为有效控制该病害的发生危害,广东省农科院植保所研究人员试验从几种低毒杀菌剂中筛选绿色高效防治药剂。室内生物活性测定结果表明,王铜(氧氯化铜)对病原菌的最小抑制浓度为500μg/mL;离体叶片法测定结果表明,氧氯化铜有效成分为125、250、500μg/mL时,防治效
Bacterial soft rot disease is an important disease in the production of Phalaenopsis, often causing serious losses. In order to effectively control the occurrence of the disease hazards, Plant Protection Institute of Guangdong Academy of Agricultural Sciences researcher from several low toxicity fungicides screening of green and efficient control agents. The results of indoor bioassay showed that the minimum inhibitory concentration of copper (copper oxychloride) on pathogenic bacteria was 500μg / mL. The results of in vitro leaf assay showed that when the effective components of copper oxychloride were 125, 250 and 500μg / mL, Control effect
