Apple leaflet disease, also known as zinc deficiency disease, mainly has three conditions: 1 The whole tree or whole tree occurs, caused by zinc deficiency. 2 Local branches occur due to improper trimming. 3 rot disease, dry rot diseased fruit parts of the site are also often lobular disease. For the garden lobular disease, zinc supplement should be promptly applied, and zinc sulfate solution should be sprayed 10-15 days before the apple tree sprouts. Each tree was treated with 0.5-1 kg of zinc sulfate and applied in the spring. For pruning caused by local branches lobular leaflets should be weak to stay strong, less scars to start, through pruning to solve. For the lobular disease caused by the diseased tree, the prevention and treatment of diseased trees should be strengthened, and the tree vigor should be weakened and strengthened as soon as possible.
