This is a symptom of the dangers of the bacterium nuclei, which mainly endangers the leaves, straws and roots of the bacterium, in particular fibrosis, and is the most threatening place for the bacterium, and when this occurs, the local plant will suffer from malnutrition and eventually from loss of moisture. The disease is endemic, with low-temperature, high-wet springs more likely to occur, with pathogens and parasitics spreading easily, mainly through the flow of air, not only to the detriment of the roots of roots, such as pharmacists, but also to the preference for the leaching of various crops, such as crucibles, eggplants and legumes, which is a more common and persistent disease. Two major programmes for the prevention and treatment of the disease: first, field management, in the context of agricultural plant protection techniques, should be based on the principle of prevention and the treatment of pests and grasses, and, in the light of the characteristics of the disease, it is recommended that, after the long-term end of the life of the drug, we should not forget some important field work. 1. Cutting dry plants off and pulling them out for destruction, as shown by the comparison of growers over the years, the incidence of harvested dry plants is significantly lower than that of non-harvested fields, and the contrast is particularly evident. 2. In the autumn and winter, gavages should also be carried out for white plume, i. E. To keep the root of the plume warm and to reduce the occurrence of the disease in the next year by eliminating the fungus in the soil through low temperatures and direct solar radiation. 3. Rationally rare, too dense white, too weak to use too much nitrogen fertilizer are also contributing factors to the disease. Ii. Medicinal control1 and early application of bactericides to white thorium is also one of the main means of preventing the occurrence of the disease. The better protections against bacterium nucculinary disease are: kactane, methyl sulphate, paraquat sprouts, thyridium, thiform esters, etc., with any of the above fungicides, which can have a good prophylactic effect during the onset of the disease, with an average spray of 1-2 times. In the case of white bacterium, where a fungal nuclei disease has already occurred, the following options for fungicides should be based on the principle of early detection of early treatment: bacterium + sepsis, methyl sulphate + septide, phenoxylactone + gramyl, peptone + septamine, cormoli + methyl sulphides, sulfamide + sepsis, etc。
