Bacterial wilt is a common disease of eggplant, and its symptoms are characterized by leaf wilting. If it is not treated in time, the eggplant plant will die, which will seriously affect the quality and yield of eggplant. Today Xiaobian will share with you the prevention and treatment of eggplant blight.
When the eggplant blight has just occurred, the color of the leaves of the eggplant will become lighter, the leaves will appear wilting, some eggplants will all occur, and there will be wilting on only individual branches, but eventually spread to the whole eggplant It eventually leads to plant death and greatly reduces the yield of eggplant. After the plant is seriously afflicted, the leaves will gradually wither and fall off, and the inside of the rhizome will appear brown. Over time, the disease will spread to the branches. Then, the branches will gradually become hollow and fester, and if the stem is squeezed under high humidity, white mucus will appear.
Through the analysis of the characteristics of bacterial wilt, we can understand the conditions, extent and harm of the pathogenesis of bacterial wilt, and strengthening the prevention and treatment of diseases is the current priority. In order to achieve the prevention and control of eggplant bacterial wilt, we should start from different fields such as agricultural control, chemical control and biological control, use more effective and lasting methods for disease management, follow the laws of natural development, protect the environment, and use green and environmentally friendly methods. The prevention and control of bacterial wilt is the prerequisite for the development of ecological agriculture and green agriculture, which can greatly increase the yield of eggplant.
1 Agricultural control
The prevention and control of eggplant bacterial wilt is mainly based on agricultural control, which can improve the quality of eggplant to achieve the desired effect. First of all, attention should be paid to the cultivation of eggplant seedlings. The use of disease-free bed soil or nutrient mash for seedling can enhance the immunity and resistance of eggplant seedlings, so that they are not easily attacked by bacterial wilt. Second, choose the way of grafting for cultivation. Grafting can prevent the occurrence of diseases, but also improve yield and quality. It is one of the most effective ways to prevent bacterial wilt. Through empirical analysis, the longer the rotation time, the more effective the control effect will be. Finally, we should do a good job in field management, pay attention to the rationality and scientific nature of fertilization, apply a sufficient amount of base fertilizer, and use decomposed organic fertilizer to provide the nutrients needed for the growth of eggplant seedlings. In the case of licorice irrigation, the metropolis adopts the method of drip irrigation. This irrigation method can effectively prevent the bacteria from infiltrating into the soil and affect the healthy growth of the locust.
2 Chemical control
Chemical control is another important way to prevent and cure eggplant bacterial wilt. Chemical control should start from the seed, first use 30mg/kg of neomycin to soak the seeds for 30min, then wash the seeds with water and then germination. When there is bacterial wilt, the initial solution will use a solution of 77% of the solution of the solution of the solution of the solution of the solution of the solution of the solution of the solution of the solution. It will last for about 4 times.
3 Biological control
Biological control is another important control method for eggplant bacterial wilt. The microbial pesticide Candidide solution can be selected for irrigation during the colonization of the eggplant seedlings. At the same time, it is also possible to use bio-organic fertilizer for cultivation, which has obvious effects compared with the traditional treatment method of bacterial wilt. And the experimental results show that bio-organic fertilizer has the best control effect on bacterial wilt, and the incidence is low, which can achieve long-term prevention and control of bacterial wilt.
As is known to all, in the north and south of China, the climate difference is large, the time and prevention methods of planting crop diseases and pests are different, and bacterial wilt is one of the common diseases, which brings serious harm to the growth of eggplant, so growers Be sure to take precautions in advance. The above is a small series of prevention and control methods for eggplant bacterial wilt in the southern region.
