Embodiment 1

[0026] The azadirachtin water solution for treating root-knot nematodes is prepared from the following raw materials in 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 water solvent for the treatment of root-knot nematode is as follows: the azadirachtin A, azadirachtin B and azadirachtin C of the weight are added to the water meeting the weight and stirred, so that the azadirachtin A, azadirachtin A, Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Embodiment 2

[0028] The azadirachtin water solution for treating root-knot nematodes 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 water solvent for the treatment of root-knot nematode is as follows: the azadirachtin A, azadirachtin B and azadirachtin C of the weight are added to the water meeting the weight and stirred, so that the azadirachtin A, azadirachtin A, Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Embodiment 3

[0030] The azadirachtin water solution for treating root-knot nematodes 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 water solvent for the treatment of root-knot nematode is as follows: the azadirachtin A, azadirachtin B and azadirachtin C of the weight are added to the water meeting the weight and stirred, so that the azadirachtin A, azadirachtin A, Azadirachtin B and Azadirachtin C are dissolved in water and obtained.

Abstract

The invention discloses a pesticide and especially relates to an azadirachtin aqueous solution for treating a root-knot nematode disease and a preparation method thereof. The azadirachtin aqueous solution for treating a root-knot nematode disease is prepared from 0.0045 to 0.005 parts by weight of an azadirachtin A, 0.08 to 0.12 parts by weight of an azadirachtin B, 0.14 to 0.16 parts by weight of an azadirachtin C and 0.74 to 0.75 parts by weight of water. The preparation method comprises the following steps of adding the azadirachtin A, the azadirachtin B and the azadirachtin C into water according to the above weight parts, and stirring so that the azadirachtin A, the azadirachtin B and the azadirachtin C are dissolved in water and the azadirachtin aqueous solution for treating a root-knot nematode disease is obtained. The azadirachtin aqueous solution for treating a root-knot nematode disease has characteristics of high pesticide efficiency, soil improvement effects, easy degradation, no residue, no drug resistance and good stability.

Description

[0001] technical field [0002] The invention relates to a pesticide, in particular to an aqueous solution of azadirachtin for treating root-knot nematodes and a preparation method thereof. Background technique [0003] The nematodes currently known to harm vegetables mainly include root-knot nematode high pedicle, root-knot nematode peanut, root-knot nematode northern and root-knot nematode southern. Nematodes have a wide range of hosts, often harming more than 30 kinds of vegetables such as melons, solanaceous fruits, beans, radishes, carrots, lettuce, and cabbage, and can also spread some fungal and bacterial diseases. Root-knot nematodes mainly harm the roots of various vegetables, showing that the lateral roots and fibrous roots increase more than normal, and form spherical or conical white nodules of different sizes on the fibrous roots of young roots, some of which are bead-shaped. The aboveground part of the damaged plant grows short and slow, with abnormal leaf col...
