青枯病是茄科蔬菜的重要病害,对番茄危害极大,是一种毁灭性病害。由于青枯病病原细菌能随着病株残留在土壤中越冬,并在病株残骸内营腐生生活,即使没有适当寄主,也能在土壤中存活14个月至数年之久。加上寄主范围广,如花生、芝麻、西瓜、烟草等均能罹病,给防治带来很大困难,是目前国内外正在研究和急待解决的一个重要课题。我们从1979年开始,对番茄青枯病的防治进行了连续三年的试验,取得了初步效果。
Wilt disease is an important disease of Solanaceae vegetables, a great harm to tomatoes, is a devastating disease. Bacterial wilt pathogens can survive in the soil as the diseased plants remain in the soil and live in the wreckage of the diseased plant, which can survive in the soil for 14 months to several years even without proper host. Coupled with a wide range of host, such as peanut, sesame, watermelon, tobacco and so can get sick, to control great difficulties, is currently being studied at home and abroad and an urgent issue to be solved. Since 1979, we conducted a three-year trial on tomato bacterial wilt prevention and treatment and achieved initial results.
