省农科院植保所杀虫剂开发中心,不久前研制出可替代波尔多液防治果树病害的80%高铜(三碱基硫酸铜)可湿性粉剂。目前,我国普遍使用波尔多液防治梨黑星病、炭疽病、苹果轮纹病、葡萄霜霉病等果树病害,此药多由农民用硫酸铜和石灰液配成,方法繁琐,质量不稳定,易发生药害,污染果面,降低果品质量。三碱基硫酸铜制剂含铜44—45%,粒径<5微 Provincial Institute of Plant Protection Pesticide Insecticides Development Center, recently developed an alternative to Bordeaux disease prevention and treatment of fruit trees 80% high copper (tribasic copper sulfate) WP. At present, Bordeaux mixture is widely used in the prevention and control of pear scab, anthracnose, apple rot disease, grape downy mildew and other fruit tree diseases in our country. The medicine is mostly composed of peasants using copper sulphate and lime liquid, the method is cumbersome, the quality is unstable, Easy to produce phytotoxicity, pollution of fruit surface, reducing fruit quality. Tribasic copper sulfate preparations containing 44-45% copper, particle size <5 micro
