Description

Soil fumigant compounded by chloropicrin, dimethyl disulfide and metam
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a soil fumigant compounded by chloropicrin, dimethyl disulfide and metam.
Background
Fumigants are a class of pesticides that use the vapors produced during volatilization to poison pests. Gaseous molecules enter harmful organisms to play a role in poisoning, and the gaseous molecules are different from gasified liquid, solid or compressed gas and the like. The vapor of the fumigant generally enters the respiratory system directly through the epidermis or spiracle of the pest, and then permeates into the blood to kill the pest. Its pesticidal action is generally thought to consist in a chemical action on the enzyme. For example, methyl bromide can combine with sulfhydryl to produce gradual and irreversible inhibition of various enzymes in the body of pests. Phosphine inhibits the central nerves of animals, stimulates the lungs to cause edema, resulting in the swelling syndrome of the heart. The action mechanism of the hydrogen phosphide on insects is mainly to inhibit the activity of cytochrome C oxidase and catalase in insects, so that the respiratory chain of the insects can block asphyxiation death and the accumulation death of cytotoxins such as peroxides in the insects is caused.
The chloropicrin is a colorless or yellowish oily liquid with the molecular formula CCl3NO2The chloropicrin with the molecular weight of 164.39 is commonly called nitrotrichloromethane, is a fumigant, can kill insects, bacteria and rats, can be used for fumigating grain pests, and can be used for preventing wood from corrosion, building layers and eliminating shipsPoison, soil and plant seed disinfection, etc. Dimethyl disulfide is also a soil fumigant, but it is poorly effective when applied alone. Metam is dithiocarbamic acid ester nematicide with fumigating effect, which is degraded into methyl isocyanate in soil to play the fumigating effect, and can effectively kill pests such as root-knot nematodes, weeds and the like by inhibiting biological cell division, DNA, RNA and protein synthesis and causing biological respiration obstruction, thereby obtaining clean and healthy soil. The chloropicrin, the dimethyl disulfide and the metam sodium can be used as single agents to be used as soil fumigants, but the single agents have poor using effect and weak broad spectrum, for example, the chloropicrin has good effect on pathogenic fungi but poor effect on nematodes. Therefore, the combination of appropriate soil fumigants to expand the control spectrum and control effect is an urgent problem to be solved in the field.
