Abstract

The invention relates to an agricultural composite herbicide containing two active ingredients, namely glufosinate ammonium and cyclosulfamuron. In the herbicide, the weight ratio of glufosinate ammonium to cyclosulfamuron is 0.1-1000:1, preferably 5-100:1, and the active ingredients account for 1-80 wt%, preferably 5-70 wt% of mass of the herbicide. The composite herbicide can be made into wettable powder, water dispersible granules, a suspension and a microcapsule suspension. In comparison with a single component, the composite herbicide has more remarkable performance and higher product fast-acting property. The product can be used for weed control of common uncultivated areas, orchards and farmlands, and also can be used for processing of stem leaf and soil of tolerance crop lands.

Description

technical field [0001] The invention relates to a preparation method of an agricultural compound herbicide composition, in particular to a preparation method of a mixture of two active ingredients of glufosinate-ammonium and cyprosulfuron-methyl, and belongs to the technical field of preparation methods of pesticide herbicides. Background technique [0002] Glufosinate is an organophosphorus non-selective herbicide, which can be used in orchards, vineyards, non-cultivated land, potato fields, etc. to control annual and perennial dicotyledonous and gramineous weeds, such as sagegrass, crabgrass , barnyardgrass, wild barley, multiflora ryegrass, green foxtail, golden foxtail, wild wheat, wild corn; Glufosinate-ammonium is an organophosphorus herbicide targeting glutamine synthetase (GS). Glufosinate-ammonium is a racemic mixture, and among its active ingredients phosphinothricin (PPT for short), only L-PPT has phytotoxicity. Glutamine synthetase can directly react with glufo...
