What is a bacterial disease? How to prevent and cure the disease when growing vegetables?

Many people can not distinguish between fungal diseases and bacterial diseases, which is more important for growing vegetables, once it is impossible to distinguish, it is difficult to treat the case. Today, let's take a look at what is bacterial disease. How to prevent and cure when growing vegetables?

What is a bacterial disease?

Bacterial diseases are diseases caused by bacterial bacteria, such as soft rot, canker, bacterial wilt and so on. The bacteria that invade plants are rod-shaped bacteria, and most of them have one or more flagella, which can invade through natural stomata (stomata, lenticels, water pores, etc.) and wounds, spread by running water, Rain Water, insects, etc., and spend the winter in diseased bodies, seeds and soil. It is easy to get sick under the conditions of high temperature and high humidity.

Symptoms: plants suffer from bacterial diseases, the symptoms of which are as follows:

1. Spotted type. A considerable number of plant diseases caused by Pseudomonas aeruginosa are spotted. Such as rice bacterial brown spot, cucumber bacterial angular spot, cotton bacterial angular spot and so on.

2. Ralstonia solanacearum. Generally, Pseudomonas aeruginosa infects plant vascular bundles, blocking the transport pathway and causing plant stems and leaves to wither. Such as tomato bacterial wilt, potato wilt, strawberry bacterial wilt and so on.

3. Leaf withered type. Most of them are caused by Xanthomonas aeruginosa infection, which eventually leads to leaf withering. Such as rice bacterial blight, cucumber bacterial leaf blight, konjac bacterial leaf blight and so on.

4. Ulcer type. It is generally caused by the infection of plants by Flavomonas. In the later stage, the disease spot is corked, the edge is raised, and the central depression is ulcerated. Such as citrus canker, vegetable soybean bacterial spot, tomato fruit bacterial spot and so on.

5. Deformity. Caused by the infection of wild bacillus tumefaciens, the root and neck of the plant become lateral roots and the branches are deformed, showing a tumor shape. Such as chrysanthemum root cancer and so on.

6. Rotten type. Most plants rot after being infected by Erwinia. Such as bacterial soft rot of Chinese cabbage, bacterial soft rot of Solanaceae and Cucurbitaceae crops, and basic rot of rice.

Second, how to control bacterial diseases when growing vegetables?

1. To control bacterial diseases of vegetables, such as Chinese cabbage soft rot, cucumber bacterial corner spot, bean bacterial blight, watermelon bacterial fruit rot and other diseases, spray with 100 times of 3% Zhongshengmycin at the initial stage of the disease, according to the disease, spray once every 7-10 days, spray 3-4 times. To control bacterial wilt of Solanaceae, the root can be irrigated with 1000 times of Zhongshengmycin, 400ml per plant, once every 7-10 days for 3-4 times according to the disease. The control effect can reach 99.95%, and it can also increase production to a certain extent.

2. Control and delay drug resistance and expand the scope of control. 4% Chunlei Zhongshengmycin wettable powder can be sprayed 600 times to control bacterial diseases such as gum disease of fruit trees and soft rot of cabbage.
