Professional strategies for disease management and application of water-soluble fertilizers in peanut planting

In the process of peanut planting, effective disease management and rational application of water-soluble fertilizer are the keys to improve yield and quality. In the following, we will propose a series of professional strategies for common diseases in peanut cultivation (such as leaf spot, dead seedlings, root rot, white silk disease, rust, sclerotinia disease, etc.) and the application of water-soluble fertilizers.

1. Disease management

1. Spotted disease

- Symptom recognition: round or irregularly shaped brown spots on the leaves with clear edges, and in severe cases, the leaves are yellow and fall off.

- Control strategy: choose disease-resistant varieties, reasonable crop rotation, and avoid continuous cropping. In the early stage of the disease, fungicides containing difenoconazole, propiconazole and other active ingredients can be used for spray prevention and control.

2. Dead seedlings

- Cause analysis: It is mostly caused by factors such as seed fungus, soil diseases, and improper planting management.

- Control measures: Select healthy seeds and carry out seed disinfection treatment. Sterilize the soil before sowing to improve the soil environment.

3. Root rot

- Symptom recognition: root rot, dwarf plants, yellowing of leaves.

- Control strategy: Reasonable crop rotation and avoid continuous cropping. Before sowing, soil treatment is carried out with fungicides containing active ingredients such as dimethyl and carbendazim.

4. White leap disease

- Symptom recognition: white silky hyphae appear at the base of the stem, which in severe cases leads to plant death.

- Prevention and control methods: choose disease-resistant varieties, plant reasonably densely, and keep the field ventilated and light-transmitting. In the early stage of the disease, fungicides containing active ingredients such as jinggangmycin and thiophanate-methyl can be used for spray control.

5. Rust

- Symptom recognition: yellow or orange rust spots appear on the leaves, and in severe cases, the leaves are yellow and fall off.

- Control strategy: Reasonable fertilization to enhance the disease resistance of plants. In the early stage of the disease, fungicides containing active ingredients such as triazolone and enazole can be used for spray control.

6. Sclerotinia sclerotiorum

- Symptom recognition: The appearance of black sclerotia on the base of the stem and pods, which in severe cases leads to plant death.

- Control methods: choose disease-resistant varieties and rotate crops reasonably. In the early stage of the disease, fungicides containing active ingredients such as prochloraz and iprodione can be used for spray prevention and control.

Second, the application of water-soluble fertilizer

In the process of peanut planting, the rational application of water-soluble fertilizer can effectively improve the yield and quality. Here are some suggestions:

1. Fertilization according to the growth stage: Peanuts have different nutrient requirements at different growth stages, so they should be fertilized reasonably according to the growth stage. For example, more nitrogen fertilizer should be applied at the seedling stage to promote plant growth; Phosphorus and potassium fertilizers should be applied more at the flowering and fruiting stage to improve yield and quality.

2. Choose high-quality water-soluble fertilizer: Choose water-soluble fertilizer containing nitrogen, phosphorus, potassium, trace elements and other nutrients to ensure that the plants get comprehensive and balanced nutrition.

3. Scientific fertilization methods: drip irrigation, sprinkler irrigation and other water-saving irrigation methods, combined with water-soluble fertilizer application, to improve fertilizer utilization. At the same time, care should be taken to avoid excessive fertilization, which can cause soil pollution and poor plant growth.

In conclusion, the yield and quality of peanut planting can be significantly improved through effective disease management and rational application of water-soluble fertilizer. In actual production, these strategies should be applied flexibly on a case-by-case basis to achieve the best results.
