Problems solved by technology

However, triclopyr has a single herbicidal spectrum and is ineffective against gramineous weeds. In addition, it has a large residue in the soil, and it will cause phytotoxicity to a pair of next crops or interplanted crops in forest land. Therefore, in order to completely kill forest land and non-cultivated land weeds and improve safety, triclopyr mixed with other herbicides
[0004] At present, the problem of aminopyralid residues is serious, and the amount and method of use have been strictly restricted in many countries and regions

Abstract

The invention discloses a mixed herbicide containing picloram and triclopyr, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and triclopyr 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 wheat paddocks, and is a high-quality chemical herbicide for bare places, orchards, forest lands, pastures, lawns and wheat paddocks.

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 triclopyr. The herbicide composition can be applied to post-emergence weeding in non-arable land, orchard, woodland, pasture, lawn 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] Triclopyr, chemical name: 3,5,6-trichloro-2-pyridineoxyacetic acid, chemical formula: C 7 h 4 Cl 3 NO 3 . Triclopyr is a conductive herbicide, acting on nucleic acid metabolism, causing plants to produce excess nucleic acid, causing some tissues to transform into meristems, resulting in abnormal growth of leaves, stems and roots, de...
