Soil sterilizing agent

Abstract

A disclosed soil sterilizing agent is prepared from the following raw materials in parts by weight: 5-10 parts of gleditsia sinensis Lam, 8-12 parts of fructus cnidii, 10-15 part of ulmus macrocarpa Hance, 8-13 part of cortex pseudolaricis, 10-16 part of sulfur, 5-10 part of pumpkin seed, 5-10 part of radix agrimoniae pilodae, and 8-12 part of chaulmoogratree seed. The soil sterilizing agent employs modern science and technology and biological technology, the selected raw materials are scientifically matched, and the agent is a pollution-free wide-spectrum soil special-purpose pesticide which is extracted through supercritical carbon dioxide. Compared with a water decoction process in the prior art, the effective compositions are relatively easily extracted, the traditional Chinese medicine utilization rate is high, the insecticidal effect and the sterilizing effect are relatively good, and the drug property is mild. The agent is capable of effectively killing insects, bacteria and ova in soil without polluting environment, is basically free of toxic and side effect on human and animals, is long in persistent period, low in usage amount and high in safety.

Description

technical field [0001] The invention belongs to the technical field of pesticides, and in particular relates to a soil sterilizer. Background technique [0002] my country is one of the earliest countries to use pesticides and has a very long history. In the late 1980s, organochlorine pesticides were used for sterilization, which had a great impact on the soil. With the development of pollution-free agricultural products in my country Vigorously promote the implementation, high-efficiency, low-toxicity, and low-residue pesticides are gradually favored by consumers, and the widely used pesticides are still chemical preparations after all. Although they have a good sterilization effect, this low-residue chemical It also causes pollution to the environment, has toxic and side effects on people and animals, and is not conducive to long-term development. Contents of the invention [0003] In order to solve the above problems, the invention discloses a soil sterilizing agent, whi...
