[0022] The present invention will be described in further detail below by means of specific embodiments:

[0023] The experimental site is the "Yubiyu" blood orange planting joint-stock cooperative in Bishan, Chongqing. Five groups were designed for the experiment, and each group had 30 citrus trees. From June to September, observe once a month, and record the number and area of ​​new lesions.

[0024] The first group is the blank group without any drugs.

[0025] The second group is the control group. After the foot rot is found, the soil is removed to expose the lesion, and the lesion tissue and 3cm normal tissue around the lesion tissue are scraped off with 95% alcohol-sterilized tools; after cleaning with 95% alcohol , smear a mass percentage concentration of 4% copper sulfate solution once; cover soil.

[0026] The third group is the experimental group A. After finding the foot rot, remove the soil, expose the lesion, and disinfect it with 1.5% potassium permanganate so...

Abstract

This patent belongs to the field of fruit tree planting, and specifically discloses a method for treating citrus foot rot, including the steps of dispensing, pretreatment, prespraying, ultraviolet irradiation, drug application, bandaging and soil covering. The method overcomes the technical problems of multiple application of pesticides and low cure rate in the traditional technology, and the citrus foot rot can be cured at one time by applying the invention, saving time and effort.

Description

technical field [0001] The invention relates to the field of fruit tree planting, in particular to a method for treating citrus foot rot. Background technique [0002] Citrus foot rot, also known as skirt rot, rot and brown rot, can be caused by the invasion of a variety of Phytophthora fungi.

It can spread upward to the trunk 60-70 cm above the ground, and can spread downward To the main root, lateral roots, and even fibrous roots; the transverse direction will eventually lead to the circumcision of the root neck. The bark at the diseased part is brown and rotten, often has the smell of distiller's grains. In dry climates, the tissue of the diseased part is cracked and hardened, and in humid conditions, gum flow occurs in the diseased part. The junction of the diseased part a...
