More and more people like to grow crops. The crops they grow are not only bold to eat, but also delicious and unique. Chinese cabbage is a very common dish, but many people like it. However, bacterial angular leaf spot of Chinese cabbage is very common, which will greatly reduce the yield of Chinese cabbage. In order to make Chinese cabbage grow well and yield high, it is necessary to prevent the emergence of this pathogen. What are the prevention and control methods of bacterial angular leaf spot in Chinese cabbage?

First, crop rotation can first adopt the method of crop rotation between various plants, which can reduce the occurrence of this pathogen. First of all, observe whether there is any particularly serious situation in the field where Chinese cabbage is planted. If the situation is only mild, it is enough to plant plants such as lilies in rotation for one year or several months. But if the situation is particularly serious, it will take more than two years to rotate with lily to solve this problem. This method is not only healthy and safe, but also can reduce the occurrence of germs without worrying about environmental pollution. I believe everyone who has studied biology knows that this method is very good, without the toxicity of pesticides and without the complexity of other methods.

Second, timely management If abnormal conditions are observed on the leaves of Chinese cabbage, they should be burned or buried in time. When planting Chinese cabbage, it is necessary to observe the growth of Chinese cabbage regularly and judge whether it is infected with bacterial angular leaf spot of Chinese cabbage. Of course, you should pay attention to your crops. It would be a pity if the whole farmland was abandoned just because of your own little mistake. If you have no time, you can also ask your family to help you see the growth of Chinese cabbage. If you find something abnormal, you should unplug it in time, and don't let the germs spread, otherwise it will be uncontrollable.

Third, when disinfecting the seeds of Chinese cabbage, if you are worried about safety, you can soak them in warm water of 50 degrees 15 minutes or so. This can kill bacteria on the surface of seeds and reduce the occurrence of this disease. Take it out and dry it, and you can sow it. This method is simple and time-saving, and does not need to consume a lot of manpower and material resources. Therefore, I hope that when you see that your crops have this disease, you should listen to some suggestions and take immediate action.
