In recent years, the problem of dead tomatoes has become increasingly serious. According to the survey, the tomato dead tree is mainly concentrated in two stages: one is the seedling stage, when the seedling is just planted, the stalk is young, it is easy to be burned under high temperature conditions, and the disease is dead; the second is to the tomato coloring mature period, with The nutrient consumption is getting bigger and bigger, the root system is heavy, and the stress resistance is reduced. Once infected by the bacteria, it will quickly become dead. At the moment, it is the second peak of the dead tree when the tomato is ripe. Recently, Shandong Shouguang, Laiyang and other vegetable farmers have reflected the problem of dead trees. Causes Dead trees are important in prevention. Once they occur, they spend more money and work more. They also increase the use of Chemicals, affecting the safety of vegetables. In the end, they are not necessarily cured, and have a great impact on production and quality. There are two options for preventing dead trees: The first is to choose traditional chemical pesticides and use them. The characteristics of the drug are similar to those of the "Western medicine" that we say. It is the direct killing of the pathogens in the soil. It has a quick effect, is less affected by other factors, and has a relatively stable drug effect. However, chemical pesticides are easily absorbed by soils and are less effective, especially for root diseases that occur from capillary roots such as blight and bacterial wilt. The second is the biological fungus that has emerged in recent years, which is used for root irrigation or flushing. The efficacy of the drug is similar to our "Chinese medicine", which focuses on conditioning and slow onset, but has a long-lasting effect. Of course, biological microbial agents are living microorganisms after all. Once the environment inside the shed is not suitable for microbial survival, it may cause the efficacy to decrease or even fail, and the stability of use is not as good as that of chemicals. Both types of pharmacy have their own advantages. In practice, there are a lot of successful examples. The vegetable farmers should choose the control scheme suitable for their own shed according to the actual situation in their own shed. In the greenhouse where the organic matter content is high, the soil is loose and breathable, and the temperature and humidity are suitable, it is recommended to select biological bacteria to prevent dead trees. In greenhouses with low organic matter content, serious soil deterioration, and unsuitable temperature and humidity, vegetable farmers should give priority to chemical agents with more stable effects. If a dead tree has appeared in the shed and needs immediate treatment, the best solution is to quickly use chemical agents to prevent further spread of the pathogens and increase the damage.
