Abstract

The invention discloses a mixed herbicide containing picloram and flazasulfuron, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and flazasulfuron in a mass ratio of (0.1-80): (0.1-80) as main effective ingredients. The mixed herbicide has the advantages of quick response, wide herbicide controlling spectrum, long duration, complete weed control, low residue, low toxicity, safety, environmental friendliness and the like when applied to weeding of bare places, orchards, forest lands, pastures, lawns and corn fields, and is a high-quality chemical herbicide for bare places, orchards, forest lands, pastures, lawns and corn fields.

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 sulfasulfuron-methyl. The herbicide composition can be applied to non-cultivated land, orchard, woodland, pasture, lawn and corn field for post-emergence weeding. 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] Flazasulfuron (flazasulfuron), chemical name 1-(4,6-dimethoxypyrimidin-2-yl)-3-(3-trifluoromethyl-2-pyridinesulfonyl)urea, is produced by Japan Ishihara A sulfonylurea herbicide, acetolactate synthase (ALS) inhibitor developed by Industrial Chemicals. Primarily inhibits the reaction of acetolactate synthase which produce...
