Problems solved by technology

[0003] At present, in the cultivation of fruit trees, chemical pesticides and fungicides are usually used, and the problem of environmental pollution caused by the extensive use of chemical pesticides is becoming more and more serious
At the same time, when chemical pesticides and fungicides are used, various plant pathogenic bacteria will develop drug resistance and drug resistance, which will increase the difficulty of control and even cause control failure
In addition, chemical pesticides pose a threat to beneficial organisms because they are not selective
Moreover, many chemical pesticides are non-degradable or difficult to degrade, and are easy to accumulate in animals and plants, resulting in the enrichment of pollutants

Description

technical field [0001] The invention belongs to the field of disease prevention and control of fruit trees, and in particular relates to a natural fungicide for preventing and controlling the persimmon scale of persimmon trees and a preparation method thereof. Background technique [0002] Persimmon tree is one of the main fruit tree species in my country and has a long history of cultivation in my country. Persimmon trees are highly adaptable, especially suitable for planting in vast mountainous areas. They are very popular due to their long age and high fruit yield. However, the occurrence of insect pests in the production process has a great impact on the quality and yield of fruits. Persimmon scale is one of the pests. It is widely distributed and harms the twigs, young leaves and fruits of persimmon trees. The larvae and adults like to gather under the fruits and the gaps where they connect with the persimmon pedicles. The damaged parts turn yellow at the beginning. S...
