Nursery Stock 0 views
A. Strict quarantine should be carried out when importing carnation seedlings to avoid the spread of virus-carrying plants. B. Large-scale production bases should use shoot-tip virus-free seedlings to establish virus-free mother plant gardens for cutting propagation. C. Remove infected plants as much as possible to reduce sources of infection. During cultivation and management, care should be taken to disinfect and clean tools used for taking cuttings, cutting flowers and pruning, to avoid contact transmission. D. Pay attention to controlling the transmission vector, aphids. Spray 50% menazon wettable powder at 1500 times dilution or 2.5% deltamethrin emulsifiable concentrate at 5000 times dilution to kill aphids. E. Heat treatment

Heat-treat affected plants by controlling the growing environment temperature of virus-infected plants at around 30°C for 5 days, allowing the plants to gradually adapt to high temperatures, then adjusting the environment temperature to around 38°C for 2 months, which can reduce the amount of certain viruses in the plant body.
