2. How to treat plant viral diseases?
Eliminate the pathogen or suppress its occurrence and spread; improve the disease resistance of the host plant; control or modify environmental conditions so that they favor the host plant and not the pathogen, thereby suppressing the occurrence and development of the disease. Generally, prevention is the priority, and specific integrated management measures are taken according to the time and place based on the occurrence and development patterns of crop diseases.
