柑桔溃疡病被列为国内外的植物检疫对象。苗木受害后生长受阻,严重时苗木生长矮小,叶片脱落,不能出圃,并可随苗木的调运作远距离传播。苗木一旦被侵染发生,难以消灭,并可为害成年树叶片、枝梢、果实。 自1985年开始,我们进行了不同药剂田间防治桔苗溃疡病试验,1986年发现铜氨合剂防治桔苗溃疡病效果很好。现将这一工作总结如下: 一、试验材料及方法
Citrus canker disease is listed as a phytosanitary target both at home and abroad. After the growth of seedlings blocked growth, the growth of seedlings in the dwarf, leaves fall off, can not be nursed, and can be transferred with the seedlings for long-distance transmission. Once the seedlings have been infected, it is difficult to eliminate, and can damage adult leaves, shoots, fruits. Since 1985, we conducted experiments on the prevention and treatment of the disease of orange peel and canker in the field of different medicaments. In 1986, we found that the effect of the copper and ammonia mixture on the prevention and treatment of the pellicle and canker disease was very good. Now this work is summarized as follows: First, the test materials and methods
