Control method of mango bleeding disease

Abstract

The invention discloses a control method of a mango bleeding disease. The control method takes scrapping a mango gummosis pathogenetic portion until healthy cylem is exposed. About 2cm is scraped on the mango gummosis pathogenetic portion and the healthy cylem, the scraped portion is coated by 2% of kasugamycin water aqua 50 times, 20% of bismerthiazol wettable powder 50 times and 70% of thiphanate-methyl wettable powder 50 times. By the control method, cure rate of the mango bleeding disease reaches more than 92%, and is higher of more than 20% than a common control method of the mango bleeding disease. The control method effectively controls development and spreading of a bleeding disease, and ensures mango output and income of orchard workers. Due to the adoption of the technical scheme, the control method is obvious in control effect on the mango bleeding disease, not only simple and practical in method, but also low in cost, high in cure rate, and short in cure time, and greatly reduces load of the orchard workers.

Description

technical field [0001] The invention relates to the field of plant disease prevention and control, in particular to a method for preventing and treating mango gummosis. Background technique [0002] Mango gummosis mainly harms branches and trunks, causing dryness, but it can also harm seedlings and fruits. Seedlings often suffer from dark brown necrosis spots at the bud joints or wounds, which quickly develop up and down, causing scion necrosis. The main trunk or branches are damaged, the cortex is necrotic and presents ulcer symptoms, the outflow of the diseased part is initially white and then brown gum, the branches above the diseased part are withered, and black small grains grow on them, the leaves on the dead branches are brown, rolled up, easy to fall, and the fruit It also dries and shrinks, and generally does not fall off. New shoots sometimes emerge from under the diseased part, but the growth is poor and the leaves fade. The damaged pedicel produces longitudin...

AI Technical Summary

Problems solved by technology

[0009] The above-mentioned prevention and treatment methods are labor-intensive, take a long time, and have poor therapeutic effect and low cure rate.

[0010] Generally, it is 60%~70%, which leads to a great increase in the death rate of mango trees, thereby reducing the yield per mu of mangoes and increasing the burden on fruit farmers.
