Remedial methods for pepper phytotoxicity

Pepper is easy to produce diseases and insect pests in the process of cultivation, so it is necessary to apply some pesticides for control. Sometimes drug damage can be caused by improper spraying. So, what is the remedy for pepper drug damage?

What are the remedies for drug damage caused by chili peppers?

When it is found that the pesticide is sprayed incorrectly or the concentration is too high, rinse with clean water for 2 or 3 times in time. For the pepper with symptoms of drug damage, timely ploughing and loosening soil watering and increasing application of nitrogen, phosphorus and potassium fertilizer can promote root development and enhance disease resistance. In addition, spraying foliar fertilizer can also play a certain role in alleviation.

2. Cultivation techniques of hot pepper

1. Soil preparation and fertilization

Select the land that requires convenient drainage and irrigation and loose soil. before planting, the plot is deeply ploughed at a depth of 10 to 15 centimeters, and bottom fertilizer is applied at the same time. 5000 kg of barnyard manure and 15-20 kg of calcium superphosphate are applied in the field at the same time, and ditches are opened at the same time. It is convenient not to accumulate water and irrigation.

2. Seedling planting

The early-maturing varieties are generally sown in January, and the late-maturing varieties are sown from February to March and are planted after emergence. Generally, the seedbed is watered in the morning on a sunny day and planted in the afternoon. The row spacing of precocious varieties was 40cm, the plant spacing was 26cm, and there were 2 seedlings in each hole. The row spacing of the late-maturing variety was 66-73 cm, the plant spacing was 50-60 cm, and 1 seedling was left in each hole.

3. Field management

Before harvest, it is necessary to irrigate small water, early topdressing, combined with mid-tillage, topdressing phosphorus and potassium fertilizer to promote the robust growth of seedlings, prevent falling flowers, and remove the side branches on the main stem below the first flower. Harvest time to harvest pepper in advance, timely watering soil, and topdressing fertilizer. In the hot season, watering is carried out in the morning and evening to keep the soil moist and apply a small amount of chemical fertilizer.

4. Disease control

The diseases and insect pests of pepper include bacterial wilt, powdery mildew and so on. The resistant varieties were selected and sprayed with 100~200PPM agricultural streptomycin with water at the initial stage of the disease. the roots were irrigated every 10 to 15 days for 2 to 3 times. The varieties with good resistance to powdery mildew were selected for the control of powdery mildew. Before planting, the new high lipid membrane was sprayed with 800x liquid, and at the initial stage of the disease, Duoyuqing 1000 times liquid and DuPont Fuxing 3000 times solution could be sprayed.

Pepper drug damage will seriously affect the yield and quality, we must be careful in the application.
