What medication works well to prevent and control viral diseases in flowers

For flowers suffering from viral diseases, medications such as 40% dimethoate emulsifiable concentrate (1000-1500 times dilution) can generally be used for prevention and control. Other prevention and control methods: plant flower varieties with relatively strong disease tolerance and good disease resistance (the fundamental way to prevent and control the disease), strictly select virus-free propagation materials, such as tubers, seeds, etc., to reduce sources of infection; promptly remove weeds and pay attention to sanitation within the flower planting area; after discovering diseased plants, promptly pull them out and burn them, and promptly disinfect tools that have come into contact with diseased plants.
