Last Updated: 2024/11/05, The cherry blossom mulberry white shield scale is mainly distributed in the cherry blossom cultivation area, and the occurrence is common. Because of the suitable climate and high humidity in the field, the occurrence 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 around the end of September. The newly hatched nymph stage is the best time to carry out spray control. All farmers should strengthen the field inspection and control immediately if there is any occurrence, and keep the population base below the allowable economic level. Prevention and cure method

The cherry blossom mulberry white shield scale is mainly distributed in the cherry blossom cultivation area, and the occurrence is common. Because of the suitable climate and high humidity in the field, the occurrence 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 around the end of September. The newly hatched nymph stage is the best time to carry out spray control. All farmers should strengthen the field inspection and control immediately if there is any occurrence, and keep 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.
