Description
Technical field
The present invention relates to herbicide technology fields, and in particular to a kind of weeding containing haloxyfop-r-methyl and rimsulfuron
Composition and its application.
Background technique
Rimsulfuron is sulfonylurea herbicide, branched-chain amino acid synthetic inhibitor, selective post-emergence herbicide.For preventing
Except grass family annual or perennial in milpa and broadleaf weeds, such as creeping thistle, iron shepherd's purse, the rhizome of nutgrass flatsedge, curled dock, my Bogao
Beam, wild avena sativa, Digitaria ischaemum (Schreib.) Schreib. Ex Mubl, barnyard grass, Itanlian rye, piemarker, Amaranthus retroflexus, clearvers, corn poppy, herba stellariae mediae.To annual miscellaneous
Early application after careless bud it is further preferred that, recommend dosage 5-15g effective component/hm2.For corn and potato weeding；To corn safety,
It is most safe to spring maize.Half-life period of the rimsulfuron in corn is only 6h, and when being handled with 2-4 times of recommended dose, corn is still
It is very safe.In use, having no adverse effects to succession crop, but corn, pop corn, glutinous corn and seed farm should not use.
Haloxyfop-r-methyl is a kind of selective herbicide, and it is miscellaneous to prevent and kill off various grass family for various broad leaf crop Tanakas
Grass.Obstinate gramineae weed especially perennial to reed, cogongrass, Bermuda grass etc. has brilliant preventive effect.To broad leaf crop
It is highly safe.Effect stability under cryogenic conditions.It can be absorbed quickly by the blade of gramineae weed after haloxyfop-r-methyl application,
And conduct to entire plant, inhibit plant meristem growth, to kill weeds.Lasting period is long, to after emergence arrive tiller, take out
The annual and perennial gramineae weed at fringe initial stage all has good preventive effect.Under normal use to various broad-leaveds
Plant height safety.It remains to show excellent herbicidal effect under low temperature, drought condition.
In herbicide field, in order to expand degrass spectrum, it will usually compound two or more herbicide.But
It is that many herbicides can show as addition or even antagonism after compounding, only only a few can just show synergy work
With.
