Abstract
The invention discloses a kind of Herbicidal combinations, including following active principle：Flumioxazin, pendimethalin and prometryn, the weight ratio of flumioxazin, pendimethalin and prometryn is in the Herbicidal combinations（1‑3）：（20‑40）：（20‑40）, the gross weight percentage composition of flumioxazin, pendimethalin and prometryn in the composition is 1%~80%.The present invention can be significantly expanded herbicide controlling spectrum, improve the overall preventive effect to cotton field weed, meanwhile, said composition is good to cotton safety, is a kind of extraordinary newtype drug combination for preventing and kill off Cotton Fields annual grassy weeds.
Description
Technical field
The invention belongs to agrochemicals technical field, more particularly, to a kind of Herbicidal combinations.
Background technology
Flumioxazin (flumioxazin) belongs to cyclic imides class herbicide, can be absorbed by the young shoot of plant and blade,
Conducted in plant, the synthesis for suppressing chlorophyll causes the rapid wilting, albefaction of susceptible weeds, necrosis and withered.Propine
Benfluralin is to willow leaf thorn smartweed, pale persicaria, section knotweed, piece storage, weasel hemp nettle, black nightshade, Amaranthus retroflexus, piemarker, lamb's-quarters, small lamb's-quarters, elscholtiza, water spine
Pin, Siberian cocklebur, Rumex, shepherd's purse, penny cress, dayflower etc. have good prevention effect.To annual gramineae barnyard grass, dog tail
Grass, setaria glauca, wild oat and perennial sowthistle have certain inhibitory action.
Pendimethalin (pendimethalin) chemical name N- (1- ethyl propyls) -2,6- dinitro -3,4- dimethyl benzenes
Amine, belongs to meristem cell division inhibitor.After young shoot, young stem, young root absorption medicament during suppressing weed seed germination
Work, final young shoot and secondary root are suppressed, and ultimately result in death.
Prometryn (prometryn) belongs to trichloro-benzenes, and interior extinction, which closes, suppresses herbicide, suppresses weeds tip yellow, chlorisis,
Final browning and it is withered.Prometryn broad weed-killing spectrum, can prevent and kill off the weeds such as barnyard grass, lady's-grass, moleplant seed, emarginate amaranth herb or seed, purslane.
Herbicide kind containing single-activity component on control of weeds there are it is different degrees of the defects of, as be used continuously after
Weeds easily develop immunity to drugs, and herbicide controlling spectrum narrows, the problems such as causing environmental pollution.
Rationally compounding is to improve preventive effect, expand herbicide controlling spectrum, widen usage time to herbicide, delays shift of weed community
Speed, reduce pesticide single use caused by resistance risk, mitigate the pollution to environment, reduce use cost and mitigate and remove
A kind of careless remaining effective ways of agent.
The content of the invention
The present invention is in order to overcome the deficiencies of the prior art and provide a kind of poison more high and low to crop safety, low-residual, kill
Grass spectrum is wide, can effectively delay the Herbicidal combinations of herbicide resistance.
To achieve these goals, the present invention uses following technical scheme：A kind of Herbicidal combinations, including following effective group
Point：Flumioxazin, pendimethalin and prometryn, the flumioxazin, pendimethalin and prometryn weight ratio are (1-
3)：(20-40)：(20-40).
Further, Herbicidal combinations of the present invention, it is characterised in that flumioxazin, pendimethalin and flutter grass
Net preferred weight ratio is 1:30:20.
Further, Herbicidal combinations of the present invention, it is characterised in that flumioxazin, pendimethalin and flutter grass
Net weight accounts for the 1~80% of composition total weight.
Further, Herbicidal combinations of the present invention, it is characterised in that the Herbicidal combinations formulation is wettable
Property pulvis, dispersible oil-suspending agent.
Further, Herbicidal combinations of the present invention, it is characterised in that described Herbicidal combinations formulation auxiliary into
It is divided into carrier, adhesive, surfactant etc..
Further, Herbicidal combinations of the present invention, it is characterised in that the Herbicidal combinations can be used for preventing
Except Cotton Fields annual grassy weeds.
The present invention Herbicidal combinations frequency of use and usage amount with plant growth, weeds occur, Changes in weather and
There is a small amount of change, can achieve the purpose that effectively to prevent by using appropriate dosage.
The pesticide auxiliary element such as surfactant and carrier used belongs to environmentally friendly type in the Herbicidal combinations of the present invention, low
Poison, low-residual, to cotton safety, will not produce murder by poisoning to crop, fishes and shrimps and water body in use.
In conclusion the invention has the advantages that applying conveniently, cost is low, reduces usage amount, reduces times for spraying,
Broad weed-killing spectrum, effectively can delay herbicide resistance to produce, herbicidal effect is very remarkable.

Wet powder；Processing 8 is blank control (not applying herbicide), each to handle at before seedling soil spraying after sowing cotton seed 2 days
Reason.
Respondent and method：Observe within 15 days after medication each treatment agent on cotton growth situation influence and weeds it is aggrieved
Situation.30 days after medication, range estimation barnyard grass, lady's-grass, green bristlegrass, purslane, acalypha copperleaf, black nightshade, the Weed-control effect such as field bindweed and
The total preventive effect of field weed community.
4 flumioxazin of table, pendimethalin and prometryn ternary built respectively handle field efficacy after Cotton Fields medication 30 days
Result of the test.
According to investigation, after soil is closed 15 days before cotton seedling, present invention cotton in the range of test dose emerges just
Often, it is fine to cotton safety, have no that blade such as is burnt, turns to be yellow, withering at the abnormal phenomenon.The present invention is in certain medication as can be seen here
To cotton safety in dosage range.
As can be seen that the Herbicidal combinations pair of the present invention from 30 days result of the tests after the field control effectiveness test medication of table 4
Closed soil treatment prevents and kill off the barnyard grass of annual grassy weeds, lady's-grass, green bristlegrass, purslane, acalypha copperleaf, black nightshade, Tian Xuan in face of cotton
For the preventive effect of the weeds such as flower more than 95%, herbicidal effect is substantially better than the preventive effect of single dose, while expands herbicide controlling spectrum.
During the patented invention, also many embodiments are numerous to list herein.
To sum up indoor biometrics experiment and field control effectiveness test result confirm that the present invention contains flumioxazin, pendimethalin
With the Herbicidal combinations of prometryn, it is mainly used for preventing and kill off Cotton Fields annual grassy weeds, to field grass family, Cyperaceae and broad-leaved
Weeds have good preventive effect, and to cotton safety.Herbicidal combinations of the present invention have the mechanism of action unique, use agent
Measure it is low, the advantages that broad weed-killing spectrum, herbicidal effect is outstanding.
It can be seen from the above that the Herbicidal combinations containing flumioxazin, pendimethalin and prometryn are in certain dosage
In the range of to cotton safety and herbicidal performance it is excellent, have potential agricultural extension value.
Although above the present invention is described in detail with a general description of the specific embodiments, at this
On the basis of invention, further modification or improvement can be made to it.This will be apparent to those skilled in the art.Cause
This, these modifications or improvements, belong to the scope of protection of present invention without departing from theon the basis of the spirit of the present invention.
