Description
Technical field
The present invention relates to technical field of pesticide combination, more particularly to a kind of removing containing pyraclonil and Pendimethalin
Careless composition.
Background technology
The entitled 1- of chemistry (the chloro- 4,5,6,7- tetrahydro-pyrazoles of 3- simultaneously [1,5-a] pyridine-2- bases)-5-{ methyl of pyraclonil
(2 alkynyl of propyl-) amino } pyrazoles -4- nitriles, registration number is RN158353-15-2 in CAS (chemical abstracts), it is known that in WO94/
08999, the herbicide effect of the compound also describes wherein.
Pendimethalin is a kind of outstanding dry crop selective herbicide, can be widely applied to corn and soybean, flower
The field weeding of the various crops such as life, cotton, direct-seeding dry rice, potato, tobacco, vegetables.It is removed greatly currently, pendimethalin is the world the 3rd
Careless agent, sales volume are only second to steriland herbicide glyphosate, paraquat, and the maximum selective herbicidal of sales volume in the world
Agent.Pendimethalin be selective bud before, upland field soil handles herbicide after bud.Weeds absorb medicine by the young shoot sprouted
Agent inhibits the mitosis of plant cell into the medicament and tubulin binding in plant, to cause weeds dead.
Rational chemical herbicide compounding or mixture, which have, expands herbicidal spectrum, improves control effect, extends the optimum period for applying fertilizer, subtracts
Few dosage reduces poisoning, 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 double based on the indoor screening and field trials
Azoles oxalic acid dinitrile is compounded with Pendimethalin, has apparent synergistic effect.And it is removed with what Pendimethalin compounded about pyraclonil
It has not been reported so far for careless composition and application.

Specific implementation mode
To make technical scheme of the present invention, purpose and advantage be more clearly understood, present invention following specific examples
It illustrates, but the present invention is not limited to these examples.The effect experiment of the present invention uses indoor biometrics and field trial phase
In conjunction with mode, unless otherwise instructed, ratio mentioned below all be quality parts ratio.
Embodiment：Pyraclonil and Pendimethalin virulence experiment with different proportions.
1.1 reagent agent：
96% pyraclonil active compound, 97% Pendimethalin active compound, above-mentioned active compound are had by extra large Lear medicine company share
Research and development department of limit company provides.
1.2 experiment targets：
Green bristlegrass.
1.3 experimental procedure：
Using potting cauline leaf process method (NY/T1155.4-2006):It is built-in quantitative in the polypots of high 6 ㎝, 9 ㎝ of diameter
Soil will be placed on culture in greenhouse for the 15-20 sowings of examination target weeds seed in polypots after covering the fine earth of 0.5-1 ㎝ thickness,
It waits for that weeds grew to the 2-4 leaf phases and carries out cauline leaf spraying treatment, per alms bowl hydrojet 1mL, often 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 routine observation target weeds, estimated after 15d target by
Evil symptom and growth inhibition situation, and claim aerial part fresh weight or strain fresh weight, medicament is evaluated to target with report fresh weight inhibition rate
The toxicity action of weeds.
1.4 control time：
Target damage symptoms 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, fresh weight inhibition rate (%) is calculated.
Fresh weight inhibition rate P (%)=(control fresh weight-processing fresh weight)/processing fresh weight × 100%.
Synergy evaluation method：
Herbicide mode of application (NY/T1155.7-2006) is evaluated according to Gowing methods, formula is as follows：
E0=X+Y-XY/100
In formula, X is the fresh weight inhibition rate to target weeds when pyraclonil is applied alone with certain dosage；
Y is the fresh weight inhibition rate to target weeds when Pendimethalin is applied alone with certain dosage；
E0To the theoretical value of target weeds fresh weight inhibition rate for pyraclonil and when two kinds of pharmacy mix of Pendimethalin；
To the measured value of target weeds fresh weight inhibition rate when E is pyraclonil and two kinds of pharmacy mix of Pendimethalin.
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 pyraclonils are with two kinds of medicaments of Pendimethalin to the toxicity test result of green bristlegrass
Table 1 is the toxicity test result of pyraclonil and two kinds of medicament single doses of Pendimethalin
Table 2 is the toxicity test result that two kinds of medicaments of pyraclonil and Pendimethalin mix
Virulence test example shows that in active ingredient pyraclonil and Pendimethalin ratio be 1:70~70:Table when 1 dilution
Reveal certain synergistic effect, wherein pyraclonil and Pendimethalin are 4:40~40:4 synergistic effect is most apparent.Experiment
The result shows that pyraclonil and Pendimethalin Complex synergism are good in room conditions, it is proposed that suitable proportion 4:40~
40:4 or so mixture preparations carry out further field control effectiveness test, to evaluate its field practical application effect.
3, field control effectiveness test
Experiment gives birth in the Feixi County towns San He and surveys corn field proving ground, the consistent middle fertility of soil fertility, experiment
When humidity it is moderate, experimental field main weeds have lady's-grass, green bristlegrass etc., and weeding control effect is uniform.Test result is as follows：
3 pyraclonil of table compounds field efficiency test with Pendimethalin
Field experiment the result shows that ,+12% Pendimethalin of 36% pyraclonil is miscellaneous to rice terrace grass family, broadleaved herb etc.
Grass preventive effect it is preferable, estimated according to field, within the range of experimental dose, plant growth is normal, have no plant generate poisoning 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 pyraclonil and pendimethalin,
It can be widely applied to the various crops such as corn and soybean, beet, peanut, cotton, direct-seeding dry rice, potato, tobacco, vegetables field
Weeding.And to Target crops safety, compared with single dose, Herbicidal combinations of the present invention have the mechanism of action unique, have dosage few, remove
Grass is general more extensively, and the lasting period is longer, the obvious advantages such as more environmentally-friendly.So research and development and popularization of the invention have it is great
Social effect and environment protection significance.
