严防药害杀菌剂药害的产生有多种原因,一般水溶性较强的药剂容易发生药害。另外,不同作物对药剂的敏感性不同,例如波尔多液一般不会造成药害,但对铜敏感的作物却可能产生药害。豆类、马铃薯、棉花对石硫合剂敏感,药害的概率较高。提醒:药害产生与气象条件如气温、日照等有一定关系,一般高温干旱、日照强烈或雾重、高湿等条件下用药极易引起作物药害。
Prevent phytotoxicity There are many reasons for phytotoxicity, the general strong water-soluble pharmaceutical prone to phytotoxicity. In addition, the sensitivity of different crops to different agents, such as Bordeaux mixture generally does not cause phytotoxicity, but copper-sensitive crops may produce phytotoxicity. Beans, potatoes, cotton on the sulfur-sulfur mixture sensitive, the higher the probability of injury. Reminder: Phytosanitary conditions and weather conditions such as temperature, sunshine and so have a certain relationship, the general high temperature and drought, strong sunshine or heavy fog, high humidity and other conditions can easily lead to crop injury.
