Nuisance free pesticides and preparation method thereof

Abstract

The invention relates to a non-polluted pesticide and a preparation method thereof. The preparation method comprises the following steps: 10 portions to 25 portions of oleander (one or all of leaves, roots, barks and branches), 45 portions to 65 portions of red dry chilies (with seeds) and 10 portions to 20 portions of ginkgo leaf are mixed and crushed to 100 to 200 meshes of fineness, the obtained mixture is soaked into water, the weight of which is 5 times to 10 times of the mixture; the soaking time is 3 to 10 days according to the temperature, and the leach liquor is filtered, centrifugated and deslagged. The leach liquor is concentrated, and is added with an emulsifying agent so as to obtain a finished product. The invention overcomes the defects that the existing pesticide pollutes the environment, toxic ingredients are residual, drug resistance of pests is increased and the production cost of farmers is increased year by year, provides a pesticide which has good desinsection effect, no toxicity and harm to human and animals and no residue, is easy to decompose when the pesticide is applied into the earth and has no pollution to the environment. The invention has no waste, simple production technique, low input cost, easy promotion and application as well as wide market prospect.

Description

technical field [0001] The invention belongs to the field of pesticides, in particular to a pollution-free pesticide prepared from the outer testa of capsicum, oleander and ginkgo and a method thereof. Background technique [0002] Chemical pesticides, in the past period of time, have played an indelible role in increasing agricultural production, but their disadvantages have become increasingly prominent: pollution of the environment, residues of toxic ingredients, increased resistance of pests, and increased production costs for farmers. Research on pesticides has been on the rise. Looking at the published patents on pollution-free pesticides, the focus of research is on pollution-free pesticides, while ignoring the interests of farmers who use pesticides. The best pollution-free pesticides, in front of prices, they Harmful pesticides will still be made. For example, capsaicin is a pollution-free pesticide that uses capsaicin as a raw material.

[0002] Chemical pesticides, in the past period of time, have played an indelible role in increasing agricultural production, but their disadvantages have become increasingly prominent: pollution of the environment, residues of toxic ingredients, increased resistance of pests, and increased production costs for farmers. Research on pesticides has been on the rise. Looking at the published patents on pollution-free pesticides, the focus of research is on pollution-free pesticides, while ignoring the interests of farmers who use pesticides. The best pollution-free pesticides, in front of prices, they Harmful pesticides will still be produced

For example, capsaicin is a pollution-free pesticide that uses capsaicin as a raw material. Capsaicin has a significant insecticidal effect, but capsaicin has a large gap in food and medicine, with a supply-demand ratio of 1:2, and most of them rely on imports, which are expensive. Up to $40,000, daunting pesticide makers and daunting farmers

So far, no pollution-free pesticides and patents that are cheap and popular with farmers have come out
