1, strict quarantine. Chrysanthemum virus disease strains are toxins, and strict quarantine should be conducted during introduction to prevent human transmission of viruses to virus-free areas or from virus areas to expand the scope of wards. 2, prevention and control mediators. For the prevention and control of aphids, 40% omethoate or dimethoate 2000 times solution, or 50% malathion, 20%, and 70% propylamidine, each 1000 times. 50% WP WP 2000 ~ 3000 times, spraying peach Tao has a special effect. Dimethoate, malathion, and other insecticides also have good control effects on hummer horses. In addition, using the deterrent effect of silver-grey film, it also has a good effect in repelling worms and other mediator insects. 3, breeding disease-free propagation material. From the virus-free plants, strips were used as propagation materials; conditional available stem tips were used to culture and propagate non-toxic seedlings. Poisoned potted chrysanthemums were placed at 36 degrees for 3 to 4 weeks to remove the virus. After heat-treated chrysanthemum, the virus has been passivated and can be used as a propagation material. 4, pay attention to cleanliness. In conservation management, activities such as transplanting seedlings, pruning, picking and cutting flowers, etc., all have the risk of transmitting viruses. Because we should pay attention to the sanitization of hands and tools, it is best to wash hands with soap before operation, and first arrange healthy plants, after finishing diseased plants or diseased plants, to avoid human exposure to drug transmission.
