Problems solved by technology

The course of the disease is sometimes very short (within a year) and sometimes very long (a few years). After the plants lose their economic value, they not only occupy the land, but also the source of disease diffusion, affect the management of the orchard, and may cause the initial investment to be unrecoverable or delayed. Therefore, a kind of Ways to Control Avocado Root Rot and Change the Situation

Embodiment example 1

[0025] A method for preventing and treating avocado root rot, which comprises the following steps and methods:

[0026] Remove the canopy of the seriously endangered diseased tree, saw off the main pole at a distance of 0.8-0.9 meters from the ground, trim the wound with a sharp knife, and then use big tree wound smear or plant wound healing agent on the wound smear. Then, use the combination of control and promotion, and apply pesticides in the rhizosphere; control refers to controlling the number of pathogenic bacteria in the rhizosphere soil, and must use bactericides such as agricultural copper sulfate 200 times, wherein the mass concentration of copper Cu ≥ 25%; The growth of new roots and the germination of new shoots, the way to promote the growth of new roots is to apply rooting agents in the rhizosphere, such as the rooting agent produced by Guangdong Plant Dragon Biotechnology Co., Ltd. - "root burst", diluted 600 times, 20-100 kg per plant The method to promote the...

Embodiment example 2

[0033] A method for preventing and treating avocado root rot, which comprises the following steps and methods:

[0034] Remove the crown of the seriously endangered diseased tree, saw off the main pole at a distance of 0.9-1.0 meters from the ground, and then trim the wound with a sharp knife, and then use big tree wound smear or plant wound healing agent on the wound smear. Then, use the combination of control and promotion, and apply pesticides in the rhizosphere; control refers to controlling the number of pathogenic bacteria in the rhizosphere soil, and must use fungicides such as 50% dexon WP 800 times; promote refers to promoting the growth of new roots and shoots of plants. The method of germination and promoting the growth of new roots is to apply a rooting agent in the rhizosphere, such as the rooting agent produced by Guangdong Zhulong Biotechnology Co., Ltd. - "root explosion", diluted 600 times, 20-100 kg per plant, the method of promoting the growth of new shoots ...

Embodiment example 3

[0041] A method for preventing and treating avocado root rot, which comprises the following steps and methods:

[0042] Remove the crown of the seriously endangered diseased tree, saw off the main pole at a distance of 1.0-1.1 meters from the ground, and then trim the wound with a sharp knife, and then use big tree wound smear or plant wound healing agent on the wound smear. Then, use the combination of control and promotion, and apply pesticides in the rhizosphere; control refers to controlling the number of pathogenic bacteria in the rhizosphere soil, and must apply fungicides such as 40% phosfoam WP 400 times solution; promotion refers to promoting the growth of new roots and new shoots of plants. The way to promote the growth of new roots is to apply rooting agents in the rhizosphere, such as the rooting agent produced by Guangdong Zhulong Biotechnology Co., Ltd. - "root explosion", diluted 600 times, 20-100 kg per plant, to promote the growth of new shoots It is to stren...

Abstract

The invention provides a method of preventing Persea americana Mill from suffering root rot. The method comprises the following steps: sawing off a trunk, 0.8-1.2 meters away from the ground, of a Persea americana Mill tree that is severely attacked by root rot to remove a crown; and applying a bactericide and a rooting agent to roots. According to the method, on the basis of improved cultivation and management for prevention of root diseases for Persea americana Mill, conservative treatment is conducted on trees that are mildly attacked, and crown removing and root promoting are conducted on trees that are moderately attacked or severely attacked, so the sick trees can grow new roots, new crowns and new fruits. In this way, losses are reduced, and benefits are increased.

Description

technical field [0001] The invention belongs to the fields of avocado planting and plant disease prevention and control, and in particular relates to a method for preventing avocado root rot. Background technique [0002] Avocado (Persea americana Mill), also known as avocado, camphor pear, avocado and avocado, belongs to Lauraceae (Lauraceae) avocado (PerseaMill.), native to South America, evergreen tree, is a famous tropical Fruit is also one of woody oil tree species. According to measurements, every 100 grams of pulp contains 23.49 grams of fat, 1.25 grams of protein, 5.60 grams of sugar, 1.80 grams of cellulose and a variety of vitamins. In addition, the oil content of its nuts reaches 8%-29%. Dry oil, non-irritating, low acidity, can be stored for a long time after emulsification, in addition to edible, it is also one of the raw materials of high-end skin care products and spa. Therefore, it has become more and more popular with consumers. Many people of insight have...
