Description
Technical field
The present invention relates to technical field of pesticide compounding, more particularly to a kind of weeding containing glufosinate-ammonium and flumioxazin
Composition.
Background technique
Glufosinate-ammonium is organic phosphates herbicide, and glutamine synthetase inhibitor is a kind of non-selective contact weedicide, has
Certain systemic action can be used for orchard, vineyard, bare place weeding, it can also be used to prevent and kill off to potato annual or perennial
Dicotyledonous and gramineae weed and nutgrass flatsedge etc., such as rat-tail amur foxtail, herba digitariae, barnyard grass, herba setariae viridis, wild wheat, wild corn, orchardgrass, sheep
Thatch, bent awns hairgrass, yorkshire fog grass, rye grass, reed, annual bluegrass, wild avena sativa, herba bromi japonici, clearvers, benbie, deaf nettle, dragon
Certain herbaceous plants with big flowers, quackgrass, bent grass, strokes sub- grass, field scorpion grass, Bermuda grass, Amaranthus retroflexus etc. at herba stellariae mediae.
Flumioxazin is N- phenyl neighbour's ammonia first phthalimide class that SUMITOMO CHEMICAL chemical industry Co., Ltd. formulates and develops
Herbicide.It has been investigated that flumioxazin can inhibit proporphyrinogen oxidase, it can lead to photosensitization and Cell membrane lipids
Peroxidating is total to tender and mechanism to cell membrane and causes irreversible destruction, big Tanaka, and the cauline leaf of susceptible weeds is bad after cauline leaf process
Extremely, dead after solar radiation, sensitive weeds bud necrosis, dead after of short duration solar radiation after soil treatment.
Reasonable chemical herbicide compounding or mixture, which have, expands herbicidal spectrum, improves control efficiency, extends the optimum period for applying fertilizer, subtracts
Few dosage reduces phytotoxicity, reduces positive feature, mixture of herbicides or the mixtures such as residual, the generation for delaying drug resistance and development
It is one of the most effective methods to solve the above problems.We filter out grass based on the indoor screening and field trials
Ammonium phosphine is compounded with flumioxazin, has apparent synergistic effect, and the weeding group compounded about glufosinate-ammonium with flumioxazin
Close object and using it has not been reported so far.

Specific embodiment
To make technical solution of the present invention, purpose and advantage are more clearly understood, present invention following specific embodiments
It is illustrated, but the present invention is not limited to these examples.Effect experiment of the invention uses indoor biometrics and field trial phase
In conjunction with mode, unless otherwise instructed, ratio mentioned below is all mass parts ratio.
Embodiment: glufosinate-ammonium and flumioxazin virulence experiment with different proportions.
1.1 reagent agents:
96% Glufosinate-ammonium, 96% flumioxazin raw medicine, above-mentioned raw medicine are limited by extra large Lear medicine company share
Research and development department, company provides.
1.2 test targets:
Barnyard grass.
1.3 experimental procedures:
Using potting cauline leaf process method (NY/T1155.4-2006): high 6 ㎝, 9 ㎝ of diameter polypots in dress it is quantitative
Soil will be placed on culture in greenhouse after covering the fine earth of 0.5-1 ㎝ thickness for target weed seed 15-20 sowing of examination in polypots,
Cauline leaf spraying treatment is carried out to weeds length to 2-4 leaf phase, every alms bowl hydrojet 1mL, every processing is repeated 4 times, and sets the place without medicament
Reason is control.Examination is just placed in culture in the greenhouse in after processing, the growing state of regular observation of target weeds, estimated after 15d target by
Evil symptom and growth inhibition situation, and claim aerial part fresh weight or strain fresh weight, with report fresh weight inhibition rate evaluation medicament to target
The toxicity action of weeds.
1.4 control times:
Target victim symptom and growth inhibition situation are estimated after test process 15d, and claim aerial part fresh weight.
1.5 data statistics and analysis:
According to investigation statistics, calculate fresh weight inhibition rate (%).
Fresh weight inhibition rate P (%)=(control fresh weight-processing fresh weight)/processing fresh weight × 100%.
Synergy evaluation method:
Combined action of herbicide (NY/T1155.7-2006) is evaluated according to Gowing method, formula is as follows:
E0=X+Y-XY/100
In formula, X is glufosinate-ammonium when using a single dose to the fresh weight inhibition rate of target weeds；
Y is flumioxazin when using a single dose to the fresh weight inhibition rate of target weeds；
E0To the theoretical value of target weed fresh weight inhibition rate for glufosinate-ammonium and when two kinds of pharmacy mix of flumioxazin；
To the measured value of target weed fresh weight inhibition rate when E is glufosinate-ammonium and two kinds of pharmacy mix of flumioxazin.
Evaluation criterion: work as E-E0Synergistic effect is expressed as when > 10%, as -10% < E-E0It is expressed as being added when < 10%
Effect, works as E-E0Antagonism is expressed as when < -10%.
2.1 glufosinate-ammoniums are with two kinds of medicaments of flumioxazin to the toxicity test result of barnyard grass
Table 1 is the mixing virulence measurement result of glufosinate-ammonium and two kinds of medicaments of flumioxazin
Virulence test example shows to be that 1:70~70:1 is showed when diluting in effective component glufosinate-ammonium and flumioxazin ratio
Certain synergistic effect out, wherein glufosinate-ammonium and the synergistic effect that flumioxazin is 1:20~20:1 are most obvious.Test result
Show that glufosinate-ammonium in room conditions and flumioxazin Complex synergism are good, it is proposed that left to suitable proportion 1:20~20:1
Right mixture preparation carries out further field control effectiveness test, to evaluate its field practical application effect.
3, field control effectiveness test
It is moderate to test the humidity at Wheat in Henan Province field proving ground, the consistent middle fertility of soil fertility, test, experimental field
Main weeds have clearvers, herba bromi japonici, barnyard grass etc., and weeding control effect is uniform.Test result is as follows:
2 glufosinate-ammonium of table compounds field efficiency test with flumioxazin
Field experiment the result shows that, glufosinate-ammonium and flumioxazin are compounded with 3:1 ratio to wheat paddock grass family, broadleaved herb
The preventive effect of equal weeds is preferable, is estimated according to field, and within the range of experimental dose, plant growth is normal, has no that plant generates medicine
Harmful and abnormal phenomenon, illustrates that it is safe to corn.
To sum up virulence and field experiment result verification, the present invention contain the Herbicidal combinations of glufosinate-ammonium and flumioxazin,
It is mainly used for preventing and kill off wheat paddock and prevents and kill off broadleaf weeds, gramineae weed, and to Target crops safety, compared with single dose, the present invention
Herbicidal combinations have the mechanism of action unique, there is that dosage is few, and weeding is general, and the lasting period is longer more extensively, more environmentally-friendly equal obvious
Advantage.So research and development and popularization of the invention have great social effect and environment protection significance.
