柑桔溃疡病是一种细菌性病害,被国内外列为植物检疫对象。它危害柑桔的叶片,枝梢和果实。轻者发生病斑,降低果实品质,影响商品价值和外销,重者引起落叶,落果,树势衰弱,产量降低。苗木受害后,叶片脱落,生长受阻,延迟出圃,严重时叶片落光,枝干枯死。故一旦发生病害,则难以防治。为了筛选防治柑桔溃疡病较为理想的药剂,我们于1985年进行了防治柑桔溃疡病的几种农药的药效试验。观将试验结果总结简报如下: 一、材料与方法 供试药剂有40％拌种双(南通农药厂)、
Citrus canker disease is a bacterial disease that is listed as a phytosanitary target at home and abroad. It harms citrus leaves, shoots and fruits. Light lesion occurs, reducing fruit quality, affecting the value of goods and export, severe cases caused by deciduous, deciduous trees, weak trees, reduce production. After the damage of seedlings, the leaves fall off, the growth is blocked, delay out of nursery, when the leaves are falling heavily, the branches die. Therefore, once the disease occurs, it is difficult to prevent and cure. In order to screen the ideal agent for the prevention and cure of citrus canker, we conducted the efficacy test of several pesticides to prevent and cure citrus canker in 1985. Summary of the test results summarized as follows: First, the material and methods for test agents 40% double seed dressing (Nantong Pesticide Factory)
