Natural pesticide and preparation method thereof

Abstract

The invention discloses a natural pesticide and a preparation method thereof. The natural pesticide comprises the following raw materials in parts by weight: 10-20 parts of avocado peel, 5-7 parts of reed root, 3-5 parts of mother-of-pearl, 10-12 parts of Chinese white olive, 6-8 parts of Capsicum frutescens, 6-8 parts of Cedrela sinensis, 6-8 parts of watermelon seed, 7-9 parts of gentian and 100-120 parts of purified water. The natural pesticide prepared from plants can achieve the goal of preventing and killing pests and can not pollute the environment, thereby protecting the environment and human health. The main raw materials have wide sources, and are all wild plants and edible plants. Thus, the production technique is simple and easy to popularize.

Description

technical field [0001] The invention relates to the field of crop disease and insect pest prevention, in particular to a natural pesticide and a preparation method thereof. Background technique [0002] Pesticides are used to kill insects, fungi, and other organisms that harm crop growth. The earliest pesticides used were DDT, BCH, etc. They can eliminate pests in large numbers. However, they have good stability, can exist in the environment for a long time, and accumulate continuously in animals, plants and humans, so they are eliminated. Later, organophosphorus pesticides, such as dichlorvos, were used instead of the original pesticides. However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms. Traditional pesticides and some pesticides on the existing market are mostly chemical preparations, which first pollute the environment, and then enter people's diet system through water circulation, pesticide residues, etc., endangering people...

However, they contain phosphorus, which can easily cause eutrophication of aquatic organisms

Traditional pesticides and some pesticides on the existing market are mostly chemical preparations, which first pollute the environment, and then enter people's diet system through water circulation, pesticide residues, etc., endangering people's health and safety. In the end, it is human beings who are harmed. , how to make pesticides environmentally friendly, pollution-free, low-cost, and efficient is the subject of modern pesticide research
