How to prevent and cure flower virus disease

Although there is no obvious disease of flower virus disease, it can lead to growth arrest, flower and leaf becoming smaller, plant dwarfing, deformity and other symptoms. At present, a thorough and effective treatment method has not been found. Only prevention and comprehensive treatment combined with various measures can achieve better results.

1. Select disease-resistant excellent varieties.

2. The virus-free seedlings were propagated by stem-tip virus-free and tissue culture methods, but attention must be paid to the timely prevention and elimination of virus-transmitting insects, such as aphids, otherwise they would be poisoned.

3. Spray imidacloprid, mirex or other pesticides in time to eliminate anti-aphids, leafhoppers, whiteflies and other virus-transmitting insects before transmission.

4, warm treatment, such as general seeds can be soaked in warm water of 50-55 degrees for 10-15 minutes; asexual reproductive materials can be placed under high temperature conditions for a certain time, can receive therapeutic effects.

5. Strengthen cultivation management, pay attention to ventilation and light transmission, apply fertilizer and water reasonably, promote flower growth and health, and reduce the harm of virus disease.
