Abstract

The invention relates to a sulfuryl fluoride compounding agent for efficiently killing bacteria, insects and mice, and a preparation method thereof. The compounding agent mainly comprises the following components in part by mass: 10 to 30 parts of sulfuryl fluoride, 1 to 5 parts of dcyphenothrin, 5 to 10 parts of methyl isothiocyanate, 5 to 15 parts of dimethyl disulfide, 40 to 80 parts of carbon dioxide, and 20 to 50 parts of nitrogen. The compounding agent is prepared by sequentially loading the components into a pressure container according to the vapor pressure from low to high. The sulfuryl fluoride compounding agent can be applied to the fields of health quarantine, plant quarantine, warehousing, soil disinfection, cultural relic and the like, is low in cost, has a broad application range and low poisoning danger, and meets national environmental protection requirements.

Description

technical field [0001] The invention relates to a high-efficiency sulfuryl fluoride compound agent for killing bacteria, insects and rodents and a preparation method thereof. technical background [0002] At present, the insecticidal and rodent control fumigants used in fumigation are mainly methyl bromide, ethylene oxide, phosphine, dichlorvos and sulfuryl fluoride. It is well known that methyl bromide is an effective gas insecticide fumigant. Because its ODP is 0.6, it belongs to the ozone-depleting substances (ODS) that must be phased out under the Montreal Protocol. Developed countries will completely phase out before January 2005, and developing countries will also All will be phased out by 2015. Phosphine is highly toxic, and stored grain pests have developed resistance to phosphine, and individual insect species cannot be effectively and quickly controlled, which seriously restricts the fumigation and insecticidal performance of phosphine, and the residue after fumig...
