Problems solved by technology

However, the biopesticides produced in the United States so far are only about 15%, and our country is about 2%, and the varieties and quantities of biopesticides that have been promoted and used in production are very small, and those with therapeutic effects are even rarer.
Since the 1990s, my count

Abstract

The invention relates to a natural biological composition for preventing and treating agricultural pests and a preparation method thereof. The natural biological composition is characterized by comprising the following raw materials and auxiliary materials in parts by weight: 20-50 parts of fine Elsholtzia, 60-80 parts of organic solvent (low-carbon alcohol), 4-8 parts of synergist, 1-3 parts of surfactant and 900 parts of deionized water. The effective active ingredients of the fine Elsholtzia are terpene phenolic compounds and are obtained by mixing Orthodonfordii, majoram and 2-4 kinds of vanillon, Elsholtzia stauntonii, Elsholtzia flava and Elsholtzia densa plants through ultrasonic oscillation extraction or percolation of the organic solvent. The composition of the invention is a natural biological pesticide having the advantages of safety, no environment pollution and no drug residues; the main raw materials used in the natural biological composition are effective active ingredients in two kinds of labiate accepted all around the world; and the additive, the surfactant and the organic solvent are mixed scientifically and reasonably to prepare an environment-friendly pesticide by adopting the advanced production technology.

Description

technical field [0001] The present invention relates to a high-quality product extracted from natural herbal medicines such as fenugreek, which is used for antibacterial and sterilizing, preventing and controlling agricultural diseases and insect pests, and promoting the growth of agricultural crops, specifically a natural biological composition for preventing and controlling agricultural diseases and insect pests. The invention also includes a method for preparing the composition. Background technique [0002] As we all know, plant diseases and insect pests cause about 25-75% of the total crop yield reduction, which is a huge economic loss. The annual cost of using chemical pesticides to control agricultural diseases and insect pests in the world is as high as more than 10 billion US dollars. Due to the long-term use of chemically synthesized pesticides, it has brought about a series of problems such as environmental pollution, human and animal poisoning, and increased resi...
