Abstract

The invention belongs to the field of pesticides and discloses a herbicidal composition containing diflufenican and fenoxaprop-ethyl and application thereof. The herbicide takes diflufenican and fenoxaprop-ethyl as the main active ingredients, wherein the mass ratio of diflufenican to fenoxaprop-ethyl is (1-80):(1-80) and diflufenican and fenoxaprop-ethyl account for 1-85% of the herbicidal composition by mass. The herbicidal composition can be applied to preparing the herbicides for controlling the preemergence or postemergence weeds in the barley fields and the wheat fields and especially has obvious effect on preparing the herbicides for controlling various grass and broadleaf weeds in the barley fields and the wheat fields. Compared with the single agent, the herbicidal composition delays weed resistance, has wide herbicidal spectrum and long efficacy duration and does no harm to the wheat and barley and the aftercrops on the premise of improving the drug effect.

Description

technical field [0001] The invention belongs to the field of pesticides, and relates to a herbicidal composition, in particular to a herbicidal composition containing diflufenican and fenoxaprop-p-p-ethyl and an application thereof. Background technique [0002] Diflufenican (diflufenican), also known as diflufenican, chemical name: 2,4-dichloro-2-(α,α,α-trichlorofluorom-phenoxy)-3-pyridineanilide, Belonging to pyridine herbicides, its structural formula is as follows: [0003] [0004] Diflufenamide is a carotenoid biosynthesis inhibitor, which can cause chlorophyll damage and cell rupture, causing plant death. It is a broad-spectrum selective wheat field herbicide with a long residual effect in soil. It is suitable for barley and wheat fields before germination Or post-emergence weeding. Apply 125-250g / ha pre-emergence or post-emergence to autumn sowing wheat and barley fields to control various grass weeds and broad-leaved weeds, especially weeds such as pig's weeds,...
