Abstract

The invention discloses a mixed herbicide containing picloram and clethodim, and belongs to the technical field of pesticides. The herbicide is prepared from picloram and clethodim 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, wheat paddocks and oilseed rape fields, and is a high-quality chemical herbicide for bare places, orchards, forest lands, wheat paddocks and oilseed rape 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 clethodim. The herbicide composition can be applied to post-emergence weeding in non-arable land, orchard, woodland and rapeseed 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] Clethodim (clethodim), chemical name: (E)-2-[1-(3-chloroallyloxyimino)propyl]-5-[2-(ethylthio)propyl]-3- Hydroxycyclohex-2-enone belongs to cyclohexenone herbicides. Clethodim is a highly selective systemic conduction stem and leaf treatment agent, which can be absorbed by grass weed stems and leaves, and spread to the top and node meristems, by i...
