Embodiment 1

[0012] Prepare environment-friendly pesticide for vegetables by following raw material weight and method:

[0013] The first step: raw material processing: cut the harvested tripterygium wilfordii whole plant (leaves, stems and roots, etc.) into pieces, dry them in the sun, crush them to 60 meshes, extract them aseptically with water in a closed tank, and continuously rotate the closed tank, After filtering, purifying, and concentrating, the extract of Tripterygium wilfordii is obtained; add a certain amount of dried grass root powder to 10 times the amount of absolute ethanol, soak at room temperature for 24 hours, stir in a 45-degree water bath for 8 hours, filter and concentrate under reduced pressure, and obtain the ethanol extraction Get Aconiti officinalis, Oleander, Pyrethrum respectively add three times the water of each raw material amount to decoct, then filter, merge the filtrate to obtain the extract for subsequent use;

[0014] Step 2: Mixing: Mix 20 kg of Tripter...

Embodiment 2

[0016] According to the method described in Example 1, the environmentally friendly pesticides for vegetables are prepared, and the specific consumption of each raw material of the method is as follows:

Abstract

The invention belongs to the field of pesticide, which particularly relates to the environmental-protection pesticide used for vegetables. According to the weight portions, the effective composition of the pesticide comprises the raw material extracting solution as follows: 5-10 of kusnezoff monkshood root, 5-20 of gelsemium elegans, 5-30 of tripterygium wilfordii, 5-20 of oleander and 20-40 of pyrethrum. The raw material tripterygium wilfordii of the invention has intense stomach poisoning on various agricultural fruit tree pests such as cabbage caterpillar, diamondback moth, and the like, and can cause apastia or narcotic action; the gelsemium elegans contains compounds such as terpene, flavonoid, lignanoids, coumarin, other phenyl propanoid, etc. The ethanol extract of the gelsemium elegans has excellent insecticidal activity on cabbage caterpillar. When in use, the pesticide is diluted into different concentrations by water according to different crops, effectively controls various pests such as cabbage bug, mustard aphid, cabbage army worm, and the like, and has effective control on the larva and ovum of the pests with the effective rate being more than 95%; furthermore, the pesticide has little residue after being used and has no toxicity.

Description

Technical field: [0001] The invention belongs to the field of pesticides, in particular to pesticides for vegetables. Background technique: [0002] In order to improve crop yield, quality, and obtain a good harvest, pesticides are indispensable, but the use of pesticides also has some substantial deficiencies, especially in the control of cabbage bugs, radish aphids, cabbage armyworms, beet armyworms, and cutworms. Pesticides for insects and other pests are mostly chemical pesticides at present. The use of less amount of pesticides is not effective, and the amount of more pesticides is large. The side effects are relatively large for human health, ecological environment, soil properties, and crops. Invention content: [0003] The purpose of the present invention is to overcome the above-mentioned disadvantages and provide an environmentally friendly pesticide for vegetables, which uses natural Chinese herbal medicines or plants as raw materials, is highly efficient and ha...
