Common diseases and insect pests of cherry and their control

Many diseases and insect pests of cherry are the same as those of other drupe fruit trees, which can be used for reference. The main diseases of cherry are perforation, root neck rot and visceral disease. Root neck rot often occurs on trees in the early fruit stage, causing root neck ulcers. Control methods: mainly to avoid long-term cultivation of soil in the root neck of the plant, to prevent and control the bark of underground pests. At the same time, it is necessary to check frequently, find diseased plants, scrape them in time, and disinfect them with Bordeaux pulp or stone flow mixture after scraping. If the root and neck rot is serious, the aboveground growth can be restored by spring bridging. The main pests that harm cherries are red-necked longicorn beetles, golden nematodes, small through-wing moths, ball-solid shell insects, boat-shaped caterpillars and so on. The small transparent-winged moth has one generation a year, and the larvae do harm in the cortex of the big branch. The main control measures are spraying during the peak period of adult Eclosion, painting white on the branches to prevent oviposition, and timely killing or digging when larvae are found to defecate in the field.
