Abstract

The invention discloses a soil fumigant compounded of dimethyl disulfide, nitrochloroform and abamectin and application of the soil fumigant, belongs to the technical field of pesticides for soil. The soil fumigant comprises the following active ingredients in weight percent: 38%-70% of dimethyl disulfide, 10%-60% of nitrochloroform and 0.1%-2% of abamectin. The soil fumigant provided by the invention is capable of effectively preventing and controlling soil borne pathogenic fungi, nematode and weeds and is broad in spectrum. The soil fumigant provided by the invention has obvious synergism to root-knot nematode, fusarium, phytophthora fungi, pythium fungi, basidiomycota fungi, colletotrichum fungi, cylindrocarpon fungi, pyrenochaeta fungi, rhizoctonia fungi and verticillium fungi and field weeds, and is convenient to apply and safe to crops; meanwhile, three chemicals have no residue in soil and are safe to crops.

Description

technical field [0001] The invention belongs to the technical field of soil pesticides, and in particular relates to a soil fumigant compounded with dimethyl disulfide, chloropicrin and abamectin and its application in preventing and controlling root-knot nematodes and soil-borne diseases. Background technique [0002] Soil disinfection technology is a technology that can efficiently and quickly kill pathogenic bacteria, fungi, weeds, nematodes and underground pests in the soil and inhibit their growth. With the further expansion of greenhouse cultivation area and the continuous cultivation of high value-added crops, the problem of soil-borne diseases has become more and more prominent, often resulting in reduced production and lower product quality. Therefore, soil disinfection technology is one of the important measures that can effectively control soil-borne diseases. [0003] Traditional methods of preventing and controlling soil-borne diseases include disease-resistant...
