Abstract

The invention discloses a crude herbal insecticide and process for preparation, wherein the insecticide is prepared from eight kinds of crude herbs including rhubarb horsetails, flavescent sophora root, chinaberry bark, omphalia, fruit of rangoon creeper, stem pith of the ricepapr plant, areca-nut and radix euphorbiae ebracteolatae through steps of choosing materials, proportioning, disintegrating, grinding, canning, watering, steam grilling, cooling down and immersing, filtering, depositing, filtering, concentrating, preservatively treating, homogenizingand canning.

Description

Technical field: [0001] The invention relates to a natural herbal pesticide and a preparation method thereof. Background technique: [0002] 1. All over the world, especially China, which is a big agricultural country, still uses highly toxic and high-residue pesticides in agricultural and forestry crops to kill pests in order to obtain a good harvest and profits from agricultural and forestry harvests, resulting in the loss of vegetables, fruits, tea and Excessive pesticide residues in food crops have caused frequent food poisoning incidents. According to reports, tens of thousands of people are poisoned every year due to excessive pesticide residues in vegetables, and thousands of people die; After joining the WTO, EU member states, Japan, South Korea, etc. have all raised the inspection standards for pesticide residues in my country's agricultural, forestry, and aquatic products, resulting in a sharp drop in exports and heavy losses; 3. At present, my country is also doi...

AI Technical Summary

Problems solved by technology

After joining the WTO, EU member states, Japan, South Korea, etc. have all raised the inspection standards for pesticide residues in my country's agricultural, forestry, and aquatic products, resulting in a sharp drop in exports and heavy losses; 3. At present, my country is also doing a lot of research on low Preparation of toxic biological pesticides, but most of them use Chinese herbal medicines or woody plants as raw materials, such as neem, neem, and neem leaves and bark as raw materials, which are easy to damage forest resources and cost higher

Pyrethrin is extracted from pyrethrum, so it needs to be planted in large quantities, and the plant cannot be comprehensively utilized except for extracting pyrethrin, which wastes resources to a certain extent

In short, the production of pesticides using woody plants as raw materials is likely to cause the destruction and depletion of plant resources and vegetation, and at the same time, it is easy to cause environmental pollution by "three wastes" emissions
