The main diseases of sweet cherry are peach bacterial perforation disease and round spot disease. The disease is severe in the rainy months of July, August and September. It damages branches, leaves, shoots, and fruits. If it is not controlled in time, it will cause deciduous trees. It has a bad effect on the formation of flower buds, the development of tree vigor, and flowering and fruit setting in the second year. Therefore, we should pay attention to timely spraying control, spraying 5 Baume degree of lime sulfur before germination in spring, eradication of wintering disease spores and can also control scale insects, after the harvest in late June and late July 200 times the amount of spray Bordeaux fluids prevent these diseases. Sweet cherry stem glue is a physiological disease. Injuries and sap efflux after trunk injury. The fruit of the big tree during the fruit period is seriously damaged by the stems from July to August. When the red neck beetle is seriously damaged, the flow of glue is more. Glue, when the glue is severe, it will cause great harm to the tree body. Therefore, it must be controlled in time according to the cause of the disease. Avoiding injury and irritation of branches is the only way to prevent sweet cherry trees from flowing. The main insect pest of sweet cherry is Red-necked catbird. The larvae larvae overwinter in the branches, adult emergence feudal period from late June to mid-July, spawning gaps in the main bark, larvae in the trunk and large branches of xylem from top to bottom feeding hazards. This worm is seriously endangered and difficult to control. After the trunk is devoured, it causes fluid flow, which severely weakens the tree vigor and can lead to the death of the whole tree. Control methods 1. Adults are caught manually during the adult eclosion period from June to July. 2. In early June, dipterex yellow mud was applied to the trunk and large branches to prevent spawning. 3. Inject 200-fold dichlorvos solution into the fistula and kill the internal larvae. 4. When worms are found on the branches, the newly hatched larvae should be promptly excavated. 5. The adults have chemotaxis, which can be combined with the control of Pyrosphaeridae with sweet and sour liquid. Source: Rural Economic Information
