近几年来,各地葡萄白腐病非常猖獗,一般葡萄园因此病遭受损失在10—20%,有的竞达50—70%,严重威胁葡萄的生产。用波尔多液防治,效果较差,各国所推许的福美双,在发病严重的果园,效果也不理想。为此,我们自1961年开始对此病进行研究。现将白腐病发生发展规律和防治试验部分简报如下,以供生产上参考。本试验是在泰安山东农学院农场进行的,可以代表平原地区的葡萄园。
In recent years, grapevines around the country are very rampant. Generally, the vineyards suffer losses of 10-20% of the disease and some are 50-70%, which seriously threatens the production of grapes.
