How to control cherry blossom diseases and insect pests? Please guide the methods of prevention and control of cherry blossom diseases and insect pests for reference: 1, cherry blossom diseases and pests include mulberry white shield scale, all kinds of stinging moth, apple palm moth and so on. The mulberry white shield scale is mainly distributed in the cherry blossom cultivation area, and the occurrence is common, and it is quite serious in some fields. The damage has caused the leaves to basically fall off, and the number of insect population is extremely high and dense, which can be seen as snow white in the near future. It is speculated that the first hatching stage of mulberry white shield scale should be about the end of August to the beginning of September. The newly hatched nymph stage is the best time to carry out spray control. All kinds of planting households should combine prevention and control to control the population base below the allowable economic level. Control methods: in the nymphal stage, spray 1000 Mel 1500 times liquid, kill 1500Mel 2000 times liquid or scale miling 150Mel 200 times liquid. If the insect population density is relatively high, it should be sprayed again every 7-10 days, and pesticides should be carried out alternately to prevent scale insects from producing drug resistance. In addition, cherry trees with high population density should be pruned properly and concentrated on burning treatment to prevent further spread of insect pests. 2. Spodoptera litura is mainly distributed in the cherry blossom cultivation area, and the damage is serious in individual fields. All the leaves are eaten up, leaving only bare branches. At present, the state of insects is uneven, some larvae have entered the 5th instar (the first generation), and some larvae tend to be between the 1st and 2nd instar in the initial incubation period (the second generation). At present, it is the best time for spray prevention and control, and farmers should seize the time to carry out prevention and control work. Control the harm of insect pests.
