A vegetable farmer from Yueyang City, Hunan Province asked: I have planted open-air tomatoes and now individual plants have wilting problems. At the beginning, the plants are wilting during the day and recover in the evening. The stalks turn brown to see the diseased stems. What is the problem? How to prevent?
Zhu Cuixiang: The disease was judged to be bacterial wilt by the performance of the plant and the description of the vegetable farmer. It was a bacterial disease. The leaves were light green in the early stages, and the plants died of green and dry in later stages, and they developed rapidly. The disease is conducive to disease in the case of high temperature and high humidity, so pay attention to environmental regulation; In addition, should be promptly used orange bright, copper quinoline, copper bacteria such as thiamine copper rooting.
