Abstract

The invention discloses a mixed herbicide containing picloram and propaquizafop, belonging to the technical field of herbicides. The herbicide is prepared by taking picloram and propaquizafop as main effective components, wherein the mass ratio of picloram to propaquizafop is (0.1-80): (0.1-80). The mixed herbicide disclosed by the invention is applied to weeding in uncultivated areas, gardens, forest lands, oilseed rape fields and wheat paddocks, particularly has a remarkable effect when being applied to prevention and control of various broadleaf weeds in the uncultivated areas, the gardens, the forest lands and the oilseed rape fields, and has the advantages of high effect taking speed, wide herbicide control spectrum, long lasting period, weeding thoroughness, low residual quantity, 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 aclofenac-methyl. The herbicide composition can be applied to post-emergence weeding in non-arable land, orchard, woodland, rapeseed field and wheat field. Background technique [0002] Aminopyralid, chemical name: 4-amino-3,6-dichloropyridine-2-carboxylic acid, molecular formula: C 6 h 4 Cl 2 N 2 o 2 , whose structural formula is: [0003] [0004] Aminopyralid is a pyridine herbicide widely used in the control of weeds in mountains, grasslands, lawns, plantations and non-cultivated lands. Can control annual or perennial broadleaf weeds. [0005] Propaquizafop is a high-efficiency aryloxyphenoxycarboxylic acid chiral herbicide, chemical name: 2-isopropylideneaminooxyethyl (R)-2-(4-(6-chloroquinoxa Phenyl-2-yloxy)phenoxy)propionate is an acetyl-CoA carboxylase (ACCase) inhibitor, a post-em...
