Soil insecticide and use method thereof

Abstract

The invention discloses a soil insecticide. The soil insecticide is prepared from the following raw materials in parts by weight: 8 to 15 parts of sulfur, 6 to 10 parts of coptis chinensis, 3 to 8 parts of muskroot-like semiaquilegia roots, 5 to 10 parts of radix stemonae, 8 to 12 parts of common carpesium fruits, 6 to 10 parts of fructus forsythia, 5 to 10 parts of divaricate saposhnikovia roots, 5 to 8 parts of ginkgo biloba sarcotesta, 50 to 150 parts of solvent, 3 to 8 parts of emulsifier, 0.1 to 0.4 parts of thickener, 3 to 5 parts of enhancer, 0.1 to 1 part of defoamer, and 25 to 40 parts of deionized water. According to the soil insecticide disclosed by the invention, the selected natural raw materials are mild in drug properties, basically free of toxic and side effects on people and livestock, and good in insecticide and antimicrobial effects after being scientifically configured by adopting modern science and biotechnology; an insecticide killing device is simple in structure, convenient to operate, capable of retaining a high-temperature insecticide in soil for a long time and thoroughly killing harmful germs and insecticides in the soil, long in drug effect duration, and high in safety; according to the soil insecticide and a use method thereof, high-temperature steam and the insecticide are combined, physical and chemical methods act on the soil simultaneously when the high-temperature insecticide is sprayed into the soil, so that the sterilization and insecticide killing effects are good and the working efficiency is high.

Description

Technical field [0001] The invention belongs to the technical field of pesticides, and specifically relates to a soil pesticide and a method of use 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 the crop growth environment. At present, vegetables, melons and fruits in most rural areas are planted with plastic film or Switch to greenhouse planting. Greenhouse vegetables have become the mainstream products on the market. Use plastic mulching or greenhouse cultivation. A warm environment will make the fungi and insects in the soil multiply and grow rapidly. In order to eliminate harmful fungi and insects in the soil, before planting crops People use chemical pesticides, radiation, and baking to kill the soil. Because pesticides are easy to volatilize, some of them are emitte...

[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 easy to volatilize, part of them will be emitted during the spraying process, which cannot be fully utilized, and the volatilization process will harm the staff; and most of them Chemical pesticides contain harmful substances. Harmful substances remain in vegetables after growth, seriously endangering hum
