Description
Technical field
The present invention relates to a kind of Herbicidal combinations are and in particular to the Herbicidal combinations of a kind of Glufosinate-ammoniumpesticideng and sulfonylurea herbicide,
Belong to field of pesticide preparation, this Herbicidal combinations is used for preventing and treating bare place weeds.
Background technology
It is that one of Main Means of weeds are controlled on agricultural using chemical prevention and control method weeding.Particularly in forestry, orchard, non-agricultural
Field and no-tillage Tanaka, select steriland herbicide can effectively prevent and kill off multiple annual or perennial weeds, save labor cost.
The steriland herbicide being currently mainly used has glyphosate, N,N'-dimethyl-.gamma..gamma.'-dipyridylium etc., but because single, large area in recent years uses, leads
Cause herbicide resistance more and more higher, using dosage also increases therewith, and with the appearance of high anti-weeds, glyphosate, N,N'-dimethyl-.gamma..gamma.'-dipyridylium make
With during have certain limitation.
Glufosinate-ammonium is a kind of non-selective, wide spectrum, contact killing type herbicide, can suppress L-Glutamine synthesis in plant body, leads to plant
In object, nitrogen metabolism is disorderly, ammonium ion accumulation, and chloroplast disintegrates, thus photosynthesis are suppressed, ultimately results in Plant death.
Glufosinate-ammonium can be used for orchard, vineyard, bare place prevent and kill off annual or perennial dicotyledonous and grassy weed, such as Salvia japonica Thunb.,
Amur foxtail, Herba Digitariae, barnyard grass, wild barley, Itanlian rye, Herba Setariae Viridis, setaria glauca, wild wheat, wild Semen Maydiss, orchardgrass, song
Awns Deschampsia caespitosa, fescue grass, yorkshire fog grass, rye grass, Paspalum distichum, phragmites communiss, annual bluegrass, Fructus Rubi corchorifolii Immaturuss, Herba stellariae mediae, Herba Galii Teneri, Canis familiaris L. tooth
Root etc., but field is using discovery, and it is poor to the effect of part weeds such as sedge weed Rhizoma Cyperi etc..In view of glufosinate-ammonium to not
With the preventive effect difference of weeds, and for avoiding the problems such as easily induce herbicide resistance using single medicament in a large number for a long time, the present invention passes through
Lot of experiments is filtered out 4 kinds of sulfonylurea herbicides and is compounded with glufosinate-ammonium, can improve glufosinate-ammonium to tolerant weeds such as Rhizoma Cyperi
Preventive effect, has obvious potentiation, can effectively prevent and kill off multiple annual or perennial weeds.

Assay method: the Herbicidal combinations test of pesticide effectiveness of the present invention subregion in the larger bare place of one piece of weed density is carried out, dispenser
Period is weeds 2～4 leaf phase, and uniform stem and leaf sprays.Select four kinds of weeds before spraying, count various weeds strain numbers, dispenser respectively
Afterwards 15d count respectively weeds death strain number, and statistical test medicament to weeds all on bare place trial zone total preventive effect.Preventing and treating knot
Fruit is shown in Table 5, and preventive effect calculates according to formula below:
Preventive effect (%)=1- (weeds strain number before weeds strain number ÷ dispenser after dispenser) × 100%
The test of pesticide effectiveness result to weeds for the table 5. glufosinate-ammonium Herbicidal combinations
Result of the test shows: glufosinate-ammonium single dose has favorable effect to gramineous weeds sativa, broad leaved weed Herba stellariae mediae, but to dried tuber
Section's weeds Rhizoma Cyperi, Herba Cyperi Difformiss effect are poor；When glufosinate-ammonium respectively with halosulfuronmethyl, pyrazosulfuron, AC322140,
When orthosulfamuron compounds, miscellaneous to the sedge weed with Rhizoma Cyperi, Herba Cyperi Difformiss as representative, the grass family with Herba Digitariae as representative
Grass, the preventive effect of broad leaved weed with Herba stellariae mediae as representative all reach more than 90%.
Examples detailed above simply technology design to illustrate the invention and technical characterstic, can not limit the protection model of the present invention with this
Enclose.Equivalent transformation or modification that all essence according to the present invention is done, all should be included within the scope of the present invention.
