Abstract

The invention discloses a control method for the leaf spot disease of zanthoxylum bungeanum, and belongs to the technical field of plant disease and pest control. In the method, the leaf spot diseaseis controlled through the three steps of exercising seedlings of a disease-resistant variety, applying nutrition fertilizer and spraying compositions for control. Different doses of compositions are sprayed according to different morbidity conditions after the fertilizer is applied to zanthoxylum bungeanum, so that the effect of suiting the remedy to the case is achieved, and the situation that the yield of zanthoxylum bungeanum is decreased or the disease of zanthoxylum bungeanum is aggravated due to too large or too small doses will not occur. According to the method, the incidence rate of the leaf spot disease is 8.19%-9.54%, the incidence rate of weeds is 1.79%-2.17%, the disease control effect is 94.58%-96.17%, and the per-mu yield is 940-948 kg / mu and is increased by 34.3%-35.4% compared with the contrast per-mu yield of 700 kg / mu, so that remarkable economical benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant disease and insect pest control, and in particular relates to a method for preventing and controlling prickly ash leaf spot. Background technique [0002] Chinese prickly ash (scientific name: Zanthoxylum bungeanum Maxim.) is a small deciduous tree of Rutaceae, Zanthoxylum genus, up to 7 meters high; thorns on the stem, short thorns on the branches, and pubescent branches in the current year. The wood of Zanthoxylum bungeanum is a typical light yellow color, and the color becomes darker yellow when exposed to the air. The difference between the heart and sapwood is not obvious, the xylem structure is dense and uniform, and the longitudinal section has a silky luster. Solitary plants can also be used as protective hedges. Its peel can be used as seasoning, and aromatic oil can be extracted, and it can be used as medicine. The seeds are edible, and can also be processed to make soap. Zanthoxylum bun...
