Problems solved by technology

The emulsifiable concentrate can be diluted with water to form an emulsion. Artificial soil treatment not only solves the problem of inconvenient use, but also controls the volatilization of 1,3-dichloropropene, avoids stimulation to users and reduces the volatilization loss of active ingredients.

example 1

[0026] The content of 1,3-dichloropropene in the soil fumigation nematicide pesticide composition involved in the present invention is 90% (approximately 97% crude oil 93%), wherein the trans-isomer and cis-isomer are each about 50%; containing 5% Cottonseed oil is used as a steam suppressant, and it also contains 2% calcium dodecylbenzenesulfonate emulsifier.

example 2

[0028] The 1,3-dichloropropene trans-isomer content in the soil fumigation nematode pesticide composition involved in the present invention is 90% (approximately 97% crude oil 93%); contains 5% cottonseed oil as a transpiration agent, and additionally contains 2 % calcium dodecylbenzenesulfonate emulsifier.

example 3

[0030] The content of 1,3-dichloropropene in the soil fumigation nematicide pesticide composition involved in the present invention is 90% (approximately 97% crude oil 93%), wherein the trans-isomer and cis-isomer are each about 50%; containing 5% Mix vegetable oil as anti-evaporation agent, and also contain 2% calcium dodecylbenzenesulfonate emulsifier.

Abstract

The invention relates to a soil stifling pesticides composition for killing nematodes, wherein the composition comprises 1,3-dichloropropene cis-isomers or the mixture of cis-isomers and trans-isomers, evaporation inhibitor vegetable oil or mineral oil, emulsifier for preventing volatilization, or right amount of organic solvent. The emulsion can be prepared by watering the composition and diluting, whose application into soil treatment can solve the problem of impossibility of manual application.

Description

(1) Field of invention: [0001] The invention relates to a soil fumigation nematode pesticide composition. (2) Technical background: [0002] 1,3-dichloropropene is one of the high-boiling point by-products of 3-chloropropene or propylene oxide chemical products produced by chemical enterprises, and 1,3-dichloropropene can be separated by distillation. 1,3-dichloropropene has two isomers: cis-1,3-dichloropropene (hereinafter referred to as cis-body) and trans-1,3-dichloropropene (hereinafter referred to as trans-body) At home and abroad, it has been used as an intermediate for the synthesis of pharmaceuticals, pesticides and other chemical products. Foreign countries use special machinery to inject 1,3-dichloropropene into the soil to fumigate and kill crops and vegetable root-knot nematodes. [0003] Because 1,3-dichloropropene is highly volatile and insoluble in water, it is difficult to directly treat soil for use without special machinery. Dichloropropene is used as a p...
