Abstract

The invention relates to a cyhalofop-butyl oil suspending agent which consists of the following raw materials in percentage by weight: 15 to 25 percent of cyhalofop-butyl, 7 to 9 percent of a surfactant, 2 to 4 percent of diethyl malonate, 1 to 3 percent of fumed silica, 0.1 to 0.3 percent of simethicone, 0.2 to 0.4 percent of sodium benzoate and the balance of corn oil. The cyhalofop-butyl oil suspending agent disclosed by the invention is high in suspension rate and stable in performance. The cyhalofop-butyl oil suspending agent is mainly used for preventing and removing important grassy weeds, has high efficiency for moleplant seeds, has a certain control effect on low-age barnyard grass and can also be used for preventing and removing digitaria sanguinalis, paspalum distichum, setaria viridis, eleusine indica, alopecurus aequalis and the like.

Description

technical field [0001] The invention relates to a cyhalofop-ethyl oil suspension concentrate. Background technique [0002] Cyhalofop-ethyl, English name: cyhalofop-butyl, (R)-2-[4(4-cyano-2-fluorophenoxy)phenoxy]-butyl propionate. It is an aryloxyphenoxypropionic acid herbicide. It is a selective herbicide for paddy fields. It can only be used for stem and leaf treatment, and it is ineffective for pre-emergence treatment. [0003] Oil suspension concentrate, referred to as oil suspension concentrate, refers to a highly dispersed and stable suspension system formed by one or more active ingredients of pesticides (at least one of which is a solid technical drug) in an oil dispersion medium. Oil suspensions are generally diluted with grease for spraying, or undiluted for ultra-low volume spraying. Contents of the invention [0004] In order to solve the deficiencies in the prior art, the technical problem to be solved by the present invention is to provide a kind of cyhal...
