Abstract

The invention relates to an agricultural chemical compound herbicide for once preventing and killing weeds in paddy fields. The agricultural chemical compound herbicide is prepared by compounding fenoxaprop-p-ethyl and bensulfuron methyl, adding a compound safener of mefenpyr-diethyl and 3-benzenesulfonyl-oxazolidine-2-ketone and relative additives, not only expands a weed spectrum and once prevents and kills the weeds in the paddy fields, but also solves the hazard problem of the fenoxaprop-p-ethyl applied to the paddy fields and has wider prospects of market promotion and application.

Description

technical field [0001] The invention relates to an agrochemical compound herbicide of fenoxaprop-p-ethyl, which is mainly used for one-time control of weeds in paddy fields, is safe for crops, and belongs to the field of herbicide manufacture. technical background [0002] It is well known that fenoxaprop-ethyl-ethyl has been successfully applied to wheat, soybean, sugar beet, flax, peanut, rapeseed, potato and vegetables, and its single and compound formulations have been successfully applied to these crops. CN1631142, titled "excellent stem and leaf herbicide for wheat fields", and CN1656895, titled "preparation and application technology of herbicide composition suspension", disclose excellent herbicide compound preparations mainly used in wheat fields. However, Fenoxaprop-P-ethyl is applied to paddy fields. There are many researches at home and abroad, but few can be successfully applied in practice. change, or even die in large areas. In order to solve the problem of ...
