Mango angular leaf spot treatment method

Abstract

A mango angular leaf spot treatment method particularly includes: cutting off diseased branches, incinerating or land filling, preparing a bactericidal agent from copper sulfate with content of 95% and quick lime, spraying to a whole orchard and fruit trees, and spraying once in the same way about half a month before mango blooming. By implementation of the method, the diseased branches are cut off and subjected to incineration and land filling to thoroughly eliminate disease sources of the fruit trees, and accordingly disease propagation is effectively prevented. The bactericidal agent prepared from copper sulfate and quick lime is low in application cost due to low cost, and copper sulfate and quick lime have great treatment effects on bacterial germs, and remarkable treatment effects can be achieved by organic combination. In addition, the mango angular leaf spot treatment method is not only remarkably effective in treatment of mango angular leaf spot but also widely applicable to prevention and treatment of other diseases, thereby being wide in application range and worthy of extensive popularization.

Description

technical field [0001] The invention belongs to the technical field of fruit production management, and in particular relates to a method for treating mango horn spot disease. technical background [0002] Angular spot is also called bacterial black spot or canker. Mainly damage shoots, leaves and fruits. Small black spots the size of needleheads appear on the infected leaves of unturned green shoots, and then expand into small raised black spots with yellow halos around them. The spots are polygonal, and later the spots merge into irregular large black spots. Longitudinal streaks. There are needle-like black dots on the fruit skin at the beginning of the fruit infection, and then expand into crater-shaped dark brown ulcers, which are easy to induce the invasion of anthracnose and pedicle rot fungi. Mango-producing areas such as Guangdong, Guangxi, Hainan, and Fujian have widespread outbreaks. [0003] The primary source of infection comes from diseased seedlings, diseas...
