The virus likes a high temperature and drought environment, and the suitable temperature range is 15-35 °C, and the continuous high temperature and drought weather is generally conducive to the occurrence and epidemic of diseases.
Prevention and control methods:
1. Select disease-resistant varieties and disinfect seeds.
2. Reasonable crop rotation.
3. Cultivate robust, age-appropriate seedlings.
4. Rational dense planting.
5. Increase the application of organic fertilizer, combined with phosphorus and potassium fertilizer, and control the amount of nitrogen fertilizer.
6. Avoid too dry soil and promote healthy plant growth.
7. Eradicate viruses and mediator insects and parasitic weeds around the field, and remove the residual disease residues in the field in time after harvest, so as to reduce the source of initial infection of the virus.
8. Use 60 mesh insect-proof nets to physically isolate virus-transmitting insects, and hang yellow and blue plates to trap and kill adults. The combination of yellow and blue plates with sexual attractants is more effective.
9. Targeted selection of pesticides in different onset periods of pepper virus disease, application of plant resistance and virus passivator before the onset of the disease, and application of virus inhibitors in the early and middle stages of the disease to prevent and control the pepper virus disease.
