The main component is dimethyl disulfide, and the fumigant also comprises one or more of fumigant, bactericide or insecticide and emulsifier. The related indoor biological activity determination and further field efficacy test results of the composition show that the composition has better control effect on nematodes, fusarium, digitaria sanguinalis and piemarker in soil.
Description
Technical field
The present invention relates to a kind of soil fumigant composition, particularly a kind of soil fumigant composition that contains DMDS and materials such as other fumigant, bactericide, insecticide and emulsifier belongs to the chemical pesticide field.
Background technology
Mostly the fumigant that traditional soil disinfection is mainly adopted is Celfume (methyl bromide).The Celfume soil disinfection can be eliminated nematode in the soil, fungi, insect, weeds etc., and domestic and international application is extensive.But Celfume is a kind of material that damages the ozone layer, and in Montreal protocol, is classified as controlled substance, and use will be under an embargo in the world wide after 2015.Therefore study and searching Celfume soil-fumigating sterilization substitute and substitute technology, become the hot issue of current domestic and international research.
