Embodiment 1

[0029] The azadirachtin water solution for treating fruit tree root cancer is prepared from the following raw materials according to the stated parts by weight: 0.0045 g of azadirachtin A, 0.08 g of azadirachtin B, 0.16 g of azadirachtin C, water 0.74 g. The preparation method of the azadirachtin aqueous solution for treating fruit tree root cancer is as follows: get the azadirachtin A, azadirachtin B and azadirachtin C of the weight and add them to the water that meets the weight and stir, so that the azadirachtin A, azadirachtin Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Embodiment 2

[0031] Azadirachtin water solution for treating fruit tree root cancer, which is prepared from the following raw materials in parts by weight: 0.005 g of azadirachtin A, 0.12 g of azadirachtin B, 0.14 g of azadirachtin C, water 0.75 g. The preparation method of the azadirachtin aqueous solution for treating fruit tree root cancer is as follows: get the azadirachtin A, azadirachtin B and azadirachtin C of the weight and add them to the water that meets the weight and stir, so that the azadirachtin A, azadirachtin Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Embodiment 3

[0033] Azadirachtin water solution for treating fruit tree root cancer, which is prepared from the following raw materials in parts by weight: 0.0045 g of azadirachtin A, 0.12 g of azadirachtin B, 0.14 g of azadirachtin C, water 0.75 g. The preparation method of the azadirachtin aqueous solution for treating fruit tree root cancer is as follows: get the azadirachtin A, azadirachtin B and azadirachtin C of the weight and add them to the water that meets the weight and stir, so that the azadirachtin A, azadirachtin Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Abstract

The invention discloses a pesticide and in particular relates to an azadirachtin hydrosolvent for treating fruit tree meloidogynosis and a preparation method thereof. The azadirachtin hydrosolvent for treating fruit tree meloidogynosis is prepared from the following raw materials in parts by weight: 0.0045-0.005 part of azadirachtin A, 0.08-0.12 part of azadirachtin B, 0.14-0.16 part of azadirachtin C and 0.74-0.75 part of water. The preparation method of the hydrosolvent is as follows: adding the azadirachtin A, azadirachtin B and azadirachtin C according to the parts by weight above in water to be dissolved so as to obtain the azadirachtin hydrosolvent. The azadirachtin hydrosolvent has the characteristics of insecticide efficiency, soil improvement, high possibility of degradation, no residue, no resistance to drugs and good stability.

Description

[0001] [0002] technical field [0003] The invention relates to a pesticide, in particular to an azadirachtin aqueous solution for treating fruit tree root cancer and a preparation method thereof. [0004] Background technique [0005] Fruit tree root cancer (causative bacteria is Agrobacterium tumefaciens), also known as fruit tree root nodule, clubroot, and crown gall, is an important disease of fruit trees. The pathogen is a short rod-shaped bacterium with polar flagella. It can infect more than 300 kinds of plants in more than 60 families. The main hosts are hawthorn, apple, grape, pear, peach, apricot, persimmon, cherry, walnut, chestnut and other fruit trees and willow and other tree species. Cancer, water and nutrient circulation are blocked, the tree vigor is declining day by day, the leaves are thin and yellow, and the tree will die in severe cases. After the seedlings are damaged, their development is hindered, their growth is slow, the plants are short, and...
