Problems solved by technology

At present, the green and safe biological agents used to prevent and control fruit tree diseases are mainly living microbial pesticides, some botanical pesticides and some agricultural antibiotics. Compared with chemical pesticides, most biological pesticides are slow to take effect and have poor control effects, especially for living microorganisms that are safe for the environment Pesticides are mainly used to prevent the occurrence of diseases, and the control effect after the occurrence of diseases is relatively poor

Abstract

The invention discloses a green control method for plant powdery mildew, belonging to the technical field of plant disease control. In the method, firstly, the mixed solution of warm water and wood vinegar is sprayed for disease prevention, and after 5 to 7 hours, the mixed solution of bacillus microorganism bactericide and chitosan is used for spraying and disease prevention. The prevention and control method of the present invention is treated at the early stage of plant powdery mildew, can efficiently control the occurrence and harm of strawberry and grape powdery mildew in greenhouses, prevent the use of chemical pesticides and the risk of pesticide residues in fruits, and is conducive to the production of green high-quality fruits, which is beneficial to the realization of fruit trees. It is of great significance to improve the quality and efficiency of green, and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of plant disease control, in particular to a green control method for plant powdery mildew. Background technique [0002] Powdery mildew is one of the important diseases that often occur in plant production. When it occurs seriously, the rate of diseased leaves can reach more than 45%, and as a result, the diseased fruit rate of plants can reach more than 50%, seriously affecting the yield and quality of fruit trees. Powdery mildew bacteria grow and reproduce outside the plant surface. The way of damage is that its hyphae form spherical or finger-shaped haustoria, penetrate into the surface cells of the plant, and absorb plant nutrients, resulting in malnutrition and failure of normal growth, flowering and fruiting. The unusual characteristic of powdery mildew is that it likes humidity but is resistant to drought. When it occurs seriously, the rate of diseased leaves is more than 45%, the rate of diseased fr...
