本品属最新型有机铜杀菌剂,其杀菌效力是无机铜杀菌剂(如波尔多液)的4倍以上。因含植物生长所需的多种微量元素,酊品对细菌、真菌引起的病害具有理想防效,是常用“波尔多液”的理想换代产品,并兼有促进植物生长,治疗果树缺素症等作用。 常规“波尔多液”是石灰乳、硫酸铜反应生成的碱式铜盐悬浮液,对果树、蔬菜等作物的炭疽病、轮文病、早期落叶病、黑星病、霜霉病、疫病及细菌性角斑病等有防治作用。其缺点是配制繁琐,药效不稳定,不能用于对铜和碱敏感之作物,铜盐消耗量偏大,且易导致铜中毒,不能与常规杀虫、杀菌剂混用。由于其尚存在诸多缺点,国内外有关工作者对此进行了积极的探索,开发出了一些“波尔多液”代用品,如国外的氧化亚铜可湿粉,
This product is the latest organic copper fungicide, its bactericidal effect is inorganic copper bactericide (such as Bordeaux mixture) more than 4 times. Due to the variety of trace elements required for the growth of plants, tincture products have an ideal control effect against diseases caused by bacteria and fungi. They are ideal replacement products for commonly used “Bordeaux mixture”, and are also used for promoting plant growth and treating fruit tree deficiency. effect. Conventional “Bordeaux mixture” is a basic copper salt suspension formed by the reaction of lime milk and copper sulfate. It is used in the anthrax, whey disease, early leaf disease, scab, downy mildew, disease and bacteria Sexual angular spot disease and other prevention and treatment. The disadvantage is the complex preparation, efficacy is not stable, can not be used for copper and alkali-sensitive crops, copper consumption is too large, and easily lead to copper poisoning, can not be mixed with conventional insecticides, fungicides. Because of its many shortcomings, relevant domestic and foreign workers actively explored this problem and developed some “Bordeaux mixture” alternatives such as wettable powder of cuprous oxide abroad,
