Application technique of dimethyl disulfide as soil fumigant

Abstract

The invention relates to a soil fumigant, namely dimethyl disulfide ( another name: dimethyl disulfide, methyl disulfide, dimethyl disulfide, DMDS, C2H6S2), which is applicable to the control of crops such as vegetables, strawberries, flowers, melons, orchards, vineyards, and Chinese herbal medicines, and can effectively kill eelworms, soil-borne pathogenic fungi, weeds, underground pests, and the like in the soil. The dimethyl disulfide can be processed into missible oil, and the missible oil is applied in the field through drip irrigation; a raw medicine can be directly applied by an injection method; and the raw material can be processed into capsules to be directly used in the field.

Description

technical field [0001] The present invention relates to soil fumigant dimethyl disulfide (alias: dimethyl disulfide; Dimethyl disulfide; Dimethyl disulfide; DMDS, C 2 h 6 S 2 ) is suitable for the control of vegetables, strawberries, flowers, melons, orchards, vineyards, Chinese herbal medicines and other crops, and can effectively kill nematodes, soil-borne pathogenic fungi, weeds and underground pests in the soil. [0002] Dimethyl disulfide can be processed into emulsifiable concentrate and applied by drip irrigation in the field; the original drug can be directly applied by injection; the original drug can be processed into capsules and used directly in the field. Background technique [0003] Soil-borne diseases are a type of plant diseases caused by the infection of pathogens surviving in the soil. It is serious on vegetables, melons and fruits, and ornamental plants, especially on crops in greenhouses. Usually after 3-5 years of greenhouse cultivation, the yield a...
