First, the prevention and control methods of eggplant wilt
1. Seed disinfection: soak 50% carbendazim wettable powder in 500 times solution for 65438 0 hours. After cleaning, the seeds are air-dried before germination and sowing.
2. Scientific fertilization: Ribelli dietary fertilizer with high absorption and utilization rate can be selected by applying fully decomposed organic fertilizer, controlling the amount of nitrogen fertilizer, increasing the application of phosphorus, potassium fertilizer and trace elements.
3. Grafting Huang En: Use raw eggplant (red eggplant, Tolubam, etc.). ) as rootstock and used as scion grafting when cultivating eggplant.
4. Strengthen management: selecting disease-resistant varieties according to local conditions, implementing crop rotation, selecting disease-free seeds, cultivating in high border and timely ditching and drainage after rain are all good preventive measures.
5. Chemical control: 500 times of 50% carbendazim wettable powder or 200ml of 15% hymexazol aqueous solution 1000 times of solution can be used for root irrigation at the initial stage of the disease.
Second, matters needing attention
In case of continuous high temperature, in order to prevent eggplant from falling flowers and fruits, many farmers will dip flowers, which will increase the number of fruit drops. However, some farmers don't pay attention to nutrition supplement, and leaves will roll if they can't absorb nutrition, including some farmers who leave too much fruit, which will also lead to malnutrition.
Therefore, in plant management, it is necessary to leave flowers and fruits appropriately, and pay attention to the unified use of nitrogen, phosphorus and potassium when fertilizing. Therefore, pay attention to the use of potassium fertilizer in the future, and spray potassium dihydrogen phosphate and urea on the leaves for topdressing.
