Embodiment 1

[0022] Example 1 Extraction method of plant tissue extract A.

[0023] The extraction method of plant tissue extract A is as follows: 80 parts of calla lily rhizome, 40 parts of turmeric root, 70 parts of elderberry leaves, and 10 parts of weeping willow leaves are mashed with a tissue masher and mixed together, adding alkyl aryl 10 parts of polyoxyethylene polyoxypropylene ether, 10 parts of epoxy palm oil, 280 parts of deionized water, after stirring with a mixer for 5 minutes, the mixed liquid was placed in a centrifuge at 3000 rpm for 20 minutes, and the supernatant was taken liquid, that is, the plant tissue extract A is obtained; wherein the mass fraction ratio of calla lily rhizome, turmeric tuber root, elderberry leaf and weeping willow leaf is 8:4:7:1.

Embodiment 2

[0024] Example 2 Extraction method of plant tissue extract B.

[0025] Mix 130 parts of Cabernet Sauvignon grapes infected with grape white rot and 50 parts of deionized water with a tissue masher, add 10 parts of alkylaryl polyoxyethylene polyoxypropylene ether, and 10 parts of epoxy palm oil After stirring well, place it in a centrifuge at 5,000 rpm for 30 minutes and take the supernatant to obtain the plant tissue extract B; wherein the Cabernet Sauvignon grapes infected with grape white rot are covered with off-white fruit surface Grapes with mold.

Embodiment 3

[0026] The preparation method of the insecticide described in embodiment three for controlling cabbage caterpillar.

[0027] Get some parts of the plant tissue extract A prepared by the technical scheme described in Example 1, and several parts of the plant tissue extract B prepared by the technical scheme described in Example 2, A and B are mixed and placed in the container for every minute The shearing machine of 6000 turns shears 30 minutes, promptly makes described insecticide.

[0028] The insecticides for preventing and controlling cabbage worm were prepared by mixing A and B prepared by the method described in Example 3 in Table 1.

Abstract

The invention discloses an insecticide for preventing and controlling cabbage caterpillars. The insecticide contains plant extracts A and B. The plant tissue extract A is extracted from a mixture consisting of underground stems of alocasia macrorrhiza, turmeric root tubers, leaves of sambucus williamsii hance and leaves of weeping willow, and the plant tissue extract B is extracted from Cabernet Sauvignon infected with grape white rot, wherein the Cabernet Sauvignon infected with grape white rot are grapes of which the grape fruit surfaces are covered with grey-white mildew-shaped objects. Themass part ratio of the plant tissue extract A to the plant tissue extract B is 1:(0.1-0.5). The mixed use of the plant tissue extract A and the plant tissue extract B has a synergistic effect in preventing and controlling cabbage caterpillars. The insecticide provided by the invention has a notable effect on preventing and controlling cabbage caterpillars, and has the characteristics of high efficiency, low toxicity and low residue.

Description

technical field [0001] The invention belongs to the field of botanical pesticides and their applications. Specifically relates to an insecticide for controlling cabbage caterpillar.
