Abstract

The invention discloses a prevention method of plum leaf curl. The method comprises the concrete steps of (1) heating omethoate with the concentration being 40 percent to 80 to 85 DEG C, and keeping for 3 to 5min; (2) mixing carbendazim with the concentration being 50 percent and ethyl alcohol with the concentration being 60 percent according to the mass ratio of 3 to 1, and obtaining carbendazim-ethyl alcohol mixed liquor; (3) mixing the omethoate liquor and the carbendazim-ethyl alcohol mixed liquor according to the mass ratio of 1 to 2; (4) arranging an atomizing nozzle inside a crown of a plum tree, then spraying the mixed pesticide liquor through the atomizing nozzle, and applying the pesticide liquor to the back face of a plum leaf; (5) after 5 to 7d of spraying the pesticide liquor, spraying clean water once again. According to the prevention method of the plum leaf curl provided by the invention, innovative raw materials are adopted, and the pesticide liquor can accurately arrive to a concentrated area of pathogenic bacteria through a unique processing method and spraying method, so that an optimal sterilizing effect is achieved.

Description

technical field [0001] The invention belongs to the field of fruit and vegetable planting, and in particular relates to a method for preventing and treating plum leaf shrinkage disease. Background technique [0002] Leaf shrinkage mainly damages leaves, and can also damage flowers, young fruits and new shoots in severe cases. When the young leaves are just stretched out, they appear curly and red in color. The leaves gradually develop, and the degree of curling and shrinkage increases, resulting in corrugated bumps on the whole leaf, and in severe cases, the leaves are completely deformed. The diseased leaves are relatively hypertrophic, with uneven thickness and crisp texture, which are light yellow to reddish brown. In the later stage, a layer of off-white powder grows on the surface of the diseased leaves, which is the ascus layer of the pathogen. Diseased leaves eventually dry up and fall off. The pathogen of leaf shrinkage is Taphrina deformans (Berk.) Tul. The fungu...
