Description
Technical field
The invention belongs to agrochemicals field, problem is prevented and kill off for rice terrace annual grassy weeds is solved more particularly, to one kind
Herbicidal combinations.
Background technology
Mesotrione (mesotrione) belongs to p-hydroxybenzene pyruvic acid (HPP) ester dual oxide enzyme inhibitor (HPPD inhibitor).
Mesotrione is a kind of herbicide that corn ground weed is prevented and kill off for before seedling and after seedling, and herbicide controlling spectrum is very wide, can prevent and kill off barnyard grass,
Various weeds such as lady's-grass, black nightshade, Tong fiber crops, Siberian cocklebur.
Pretilachlor (pretilachlor) belongs to chloroacetanilide herbicides, is mainly suppressed by hindering protein to synthesize
The growth of cell.Medicament can be absorbed by plant hypocotyl, mesocotyl and plumule, and root slightly has absorption, and damage symptoms are
Acrospire is not unearthed or is stretched out from bud scale side, and distortion is unable to normal extension, stopping of growing, until dead.To barnyard grass, horse
The annual gramineous weeds such as Tang, moleplant seed have good sealing process, and remove part annual broadleaf weed and Cyperaceae
