Problems solved by technology

The soil insecticide is mild in nature, has no toxic and side effects on humans and animals, and has good insecticidal and antibacterial effects. However, when the insecticide is used, it needs to use a special insecticidal device and heat it to 135-160°C, and then use steam to treat the soil. Processing is not only complicated, but also requires special equipment

Abstract

The invention discloses a soil insecticide with a slow-release function. The soil insecticide with the slow-release function is prepared from the following ingredients: rhizoma zingiberis, artemisia argyi, agastache rugosus, areca catechu, licorice, tinospora sinensis merr, cinnamomum camphora, diatomaceous earth powder, emulsifier, dispersant, anti-foaming agent, ethyl alcohol, and deionized water. According to the soil insecticide, traditional Chinese medicine components are used as active ingredients of the pesticide, basically no toxic and side effects are on humans and animals, and the insecticidal and antibacterial effects are good; the diatomaceous earth powder is added, and the slow-release effect can be significantly improved; in order to improving the insecticidal effect, the tinospora sinensis merr is also added; the insecticide can completely eliminate harmful bacteria and insects in the soil, duration of efficacy is long, and safety is high.

Description

technical field [0001] The invention relates to the technical field of pesticides, in particular to a soil pesticide with slow-release function and a preparation method thereof. Background technique [0002] Sterilization and deworming are necessary tasks in the agricultural farming process. Sterilization and deworming are beneficial to kill bacteria and pests in the soil, reduce crop diseases and insect pests, and maintain crop growth environment. At present, vegetables and fruits in most rural areas are planted with plastic film or Switch to greenhouse cultivation. Greenhouse vegetables have become the mainstream products in the market. Planting with plastic film or greenhouses, the warm environment will make the bacteria and insects in the soil multiply and grow rapidly. In order to eliminate harmful bacteria and insects in the soil, before the crops are planted, People use chemical pesticides, radiation, and baking to kill insects on the soil. Since the pesticides are ea...
