Apple mosaic disease is a viral disease, but personally, the root cause is the weak tree vigor. Personally, I suggest that we should start with fertilization, inactivation of virus to prevent infection, pest control and load. For fertilization, we should increase the application of organic fertilizer, zinc fertilizer and boron fertilizer, and ningnanmycin should add aphid killing and whitefly killing drugs. Because the virus disease is spread by aphids and whiteflies, aphids must be eliminated, and amino oligosaccharides can also be used.
