The composition comprises cycloheximide, a mixed bacterial agent of bacillus subtilis and casein, an anti-freezing agent, a stabilizing agent, chitosan and sodium alginate. The composition prepared by the invention can effectively kill strawberry powdery mildew, and can effectively prevent and control strawberry powdery mildew.

Description

technical field [0001] The invention belongs to the technical field of powdery mildew prevention and control, and in particular relates to a composition for preventing and treating powdery mildew and a preparation method thereof. Background technique [0002] Strawberry powdery mildew is caused by the infection of the fungus Ascomycota subphylum Monothecia genus Monothecium laminae, and it is one of the main diseases in the process of strawberry planting. It is prone to disease under low temperature and high humidity conditions, the optimum temperature for disease onset is 15-25°C, and the relative humidity is above 90%; it mainly harms leaves, petioles, flowers, flower stalks and fruits. A thin layer of white hyphae grows, and then the lesion gradually expands to produce white powder, which turns reddish-brown in the later stage, causing the leaves to curl upwards into a spoon shape, the leaf margins shrivel and scorch, the flower buds do not open, and the fruits dry up.
