Abstract

The invention relates to a soil-fumigating nematicide and a using method thereof. The soil-fumigating nematicide contains 1,3-dichloropropylene trans-or cis-form body and trans-form body mixture, vegetable oil or mineral oil as a volatilization inhibitor, and a special composite emulsifier or additionally contains a proper amount of organic solvents. The nematicide is diluted by adding water and prepared into an emulsion for manually treating soil, thereby solving the problem that 1,3-dichloropropylene can not be manually used, also avoiding pricking users and reducing the volatilization losses of active constituents by controlling the volatilization of the 1,3-dichloropropylene, and the nematicide is quite suitable for preventing and controlling knot nematodes of various greenhouse vegetables comprising tomatoes, cucumbers, pumpkins, eggplants, cayenne peppers, kidney beans, cowpeas and the like and is also suitable for controlling the knot nematodes of commercial crops comprising gingers, vegetables, peanuts and the like. The soil-fumigating nematicide has ideal control effect, safety for users and the planted crops and obvious economic and social benefits.

Description

(1) Field of invention: [0001] The present invention relates to a soil fumigation nematicide and its application method, which contains 1,3 dichloropropene (1,3-dichloropropene), a special compound emulsifier, a volatile inhibitor and an emulsifiable concentrate (EC) preparation. At the same time, the present invention relates to a method for preventing and treating vegetable root-knot nematode disease by using 1,3-dichloropropene emulsifiable concentrate preparation. The composition can also be widely used for various crop root-knot nematodes and soil-transmitted plant diseases, has great application value and remarkable economic and social benefits. 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 referre...
