Abstract

The invention discloses a mixed herbicide containing aminopyralid and quinclorac, which belongs to the technical field of pesticide. The herbicide uses aminopyralid and quinclorac as main effective components, wherein the mass ratio of aminopyralid to quinclorac is 0.1-80: 0.1-80. The mixed herbicide provided by the invention is applied to non-cultivated land, orchards, woodland, paddy fields and wheat paddocks for post-emergence weeding and has the advantages of a wide weed control spectrum, fast action, high efficiency, low toxicity, safety, environment friendliness and the like.

Description

technical field [0001] The invention belongs to the technical field of pesticides, in particular to the field of herbicides, and relates to a binary compound of aminopyralid and quinclorac. The herbicide composition can be applied to post-emergence weeding in non-arable land, orchard, woodland, paddy field and wheat field. Background technique [0002] Aminopyralid (aminopyralid), chemical name: 4-amino-3,6-dichloropyridine-2-carboxylic acid, aminopyralid is a pyridine herbicide, widely used in mountains, grasslands, lawns, planting Weed control in orchards and non-cultivated land. Can control annual or perennial broadleaf weeds. [0003] Quiclorac (quinclorac), chemical name: 3,7-dichloro-8-quinoline carboxylic acid, is a new type of herbicide for pre-emergence and post-emergence rice fields developed by BASF. The drug has low dosage and long residual effect , Special effects on barnyard grass, wide application period and other advantages. Quinclorac is a hormone-type q...
