How to remedy pesticide damage in chili peppers? Practical methods you must master

During the cultivation of chili peppers, pests and diseases are likely to occur, so some pesticides need to be applied for control. Sometimes improper spraying can cause pesticide damage. So, what are the remedy methods for pesticide damage in chili peppers?

1. What are the remedy methods for pesticide damage in chili peppers?

When it is found that the wrong pesticide was sprayed or the concentration was too high, rinse promptly with clean water 2~3 times. For chili peppers that already show symptoms of pesticide damage, promptly carry out intertillage, loosen the soil and water, and apply additional nitrogen, phosphorus and potassium fertilizers, which can promote root development and enhance disease resistance. In addition, spraying foliar fertilizer can also provide some relief.

2. Cultivation techniques for chili peppers

1. Land preparation and fertilization

Choose a plot that is convenient for irrigation and drainage, with loose soil. Before planting, deep plow the plot to a depth of 10~15 cm, and at the same time apply base fertilizer, using 5000 kg of barnyard manure and 15~20 kg of superphosphate applied in the field at the same time, and also open ditches so that water does not accumulate and irrigation is convenient.

2. Seedling raising and transplanting

Early-maturing varieties are generally sown in January, and late-maturing varieties are sown in February to March. After emergence, transplanting is carried out. Generally, the seedbed is watered on a sunny morning and transplanting is done in the afternoon. For early-maturing varieties, the row spacing is 40~50 cm and the plant spacing is 26~33 cm, with 1~2 plants left per hole. For late-maturing varieties, the row spacing is 66~73 cm and the plant spacing is 50~60 cm, with 1 plant left per hole.

3. Field management

Before harvest, water lightly, topdress early, and combine with intertillage. Apply phosphorus and potassium fertilizers to promote vigorous growth of the seedlings, prevent flower drop, and at the same time remove the side branches on the main stem below the first flower. During the harvest period, harvest the first pepper early, water and earth up in time, and apply additional fertilizer. In hot seasons, water in the morning and evening to keep the soil moist, and apply a small amount of chemical fertilizer.

4. Disease control

The pests and diseases of chili peppers include bacterial wilt, powdery mildew, etc. For the control of bacterial wilt, choose disease-resistant varieties, and at the early stage of the disease use 100~200 PPM agricultural streptomycin diluted with water to spray the soil, spraying continuously 3 times, and drench the roots every 10~15 days, continuously 2~3 times. For the control of powdery mildew, choose varieties with good disease resistance, and before planting spray and disinfect with 800-fold diluted Xin Gao Zhi Mo solution. At the early stage of the disease, spray with 1000-fold diluted Duo Yang Qing solution plus 3000-fold diluted DuPont Fuxing solution.

Pesticide damage in chili peppers can seriously affect yield and quality, so everyone must apply pesticides carefully and prudently.
