Description
Technical field
The present invention relates to technical field of pesticide combination, more particularly to a kind of containing profluazol and S-metolachlor
Herbicidal combinations.
Background technology
Profluazol is proporphyrinogen oxidase inhibitor, is mainly used for winter wheat field and prevents and kill off broad leaved weed, as clearvers,
Chickweed, Polygonum weeds, compositae weeds etc..
S-metolachlor inhibits weed growth germination and seed-protein to synthesize by systemic action, is inhaled by young shoot
It receives, wherein monocotyledon weed is mainly that bud scale absorbs, and dicotyledon is absorbed by young shoot and young root, is conducted upwards, inhibits children
The growth of bud and root is unearthed before susceptible weeds are unearthed after germination or just and is poisoned to death.The mechanism of action：Main sprout inhibition
The protein synthesis of seed, secondly inhibits choline to penetrate into phosphide, and interference lecithin is formed.If soil moisture content is good, weeds are killed
Extremely in the young shoot phase, if soil moisture is few, weeds be unearthed after as rainfall, soil moisture increase, weeds absorb medicament, and grass family is miscellaneous
Careless lobus cardiacus distortion, atrophy, whole strain is withered after other leaf shrinkages, and the whole strain of broad leaved weed leaf shrinkage flavescence is withered.
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 maximally efficient method to solve the above problems.We are screened indoors on the basis of field trial, filter out fluorine
Cafenstrole is compounded with S-metolachlor, has apparent synergistic effect.And it is compounded about profluazol and S-metolachlor
Herbicidal combinations and application people there is no to report at present.

Specific embodiment
To make technical scheme of the present invention, purpose and advantage are more clearly understood, present invention specific examples below
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
With reference to mode, unless otherwise instructed, ratio mentioned below all be quality parts ratio.
Embodiment：Profluazol is tested with S-metolachlor different ratio co-toxicity.
1.1 reagent agent：
96% profluazol active compound, 96% S-metolachlor active compound, above-mentioned active compound is by extra large Lear medicine company share
Research and development department of Co., Ltd provides.
1.2 experiment targets：
Clearvers.
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 treats that weeds were grown 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 set the place without medicament
It manages as 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 claims 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 to the fresh weight inhibition rate of target weeds when profluazol is applied alone with certain dosage；
Y is to the fresh weight inhibition rate of target weeds when S-metolachlor is applied alone with certain dosage；
E0To the theoretical value of target weeds fresh weight inhibition rate during for profluazol and two kinds of pharmacy mix of S-metolachlor；
To the measured value of target weeds fresh weight inhibition rate when E is profluazol and two kinds of pharmacy mix of S-metolachlor.
Evaluation criterion：Work as E-E0Synergistic effect is expressed as during ＞ 10%, as -10% ＜ E-E0It is expressed as being added during ＜ 10%
Effect, works as E-E0Antagonism is expressed as during ＜ -10%.
2.1 profluazols are with two kinds of medicaments of S-metolachlor to the toxicity test result of clearvers
Mixing virulence measurement result of the table 1 for profluazol and two kinds of medicaments of S-metolachlor
Virulence test example shows that in active ingredient profluazol and S-metolachlor ratio be 1:50~50:During 1 dilution
Certain synergistic effect is shown, wherein profluazol and S-metolachlor are 1:20~20:1 synergistic effect is most apparent.
Result of the test shows that profluazol in room conditions and S-metolachlor Complex synergism are good, it is proposed that suitable proportion
1:20~20:1 or so mixture preparation carries out further field control effectiveness test, to evaluate its field practical application effect.
3rd, field control effectiveness test
3.1 field control effectiveness test eliminating weed in wheat field
It is moderate to test the humidity at Wheat in Henan Province field proving ground, the consistent middle fertility of soil fertility, experiment, experimental field
Main weeds have clearvers, bromegrass etc., and weeding control effect is uniform.Result of the test is as follows：
2 profluazol of table compounds field efficiency test with S-metolachlor
Field experiment the result shows that, profluazol S-metolachlor is with 3:1 ratio compounding is to wheat paddock grass family, wealthy
The preventive effect of the weeds such as leaf grass is preferable, is estimated according to field, and in the range of test dose, plant growth is normal, has no that plant produces
Crude drug evil and abnormal phenomenon, it is safe to wheat to illustrate it.
3.2 field control effectiveness tests prevent and kill off paddy field weed
Test site is located at three bridge fore-and-aft gangway village of Fuyang City Fu Chun streets, and rice varieties are II excellent 084, and pH value 7.2 belongs to flat
Original area, middle fertility, experimental field main weeds have barnyard grass, moleplant seed etc., weeding control effect is uniform.Result of the test is as follows：
3 profluazol of table compounds field efficiency test with S-metolachlor
Field experiment the result shows that, profluazol S-metolachlor is with 3:1 ratio compounding is to rice terrace grass family, wealthy
The preventive effect of the weeds such as leaf grass is preferable, is estimated according to field, and in the range of test dose, plant growth is normal, has no that plant produces
Crude drug evil and abnormal phenomenon, it is safe to rice to illustrate it.
To sum up virulence and field experiment result verification, the Herbicidal combination of the invention containing profluazol and S-metolachlor
Object is mainly used for preventing and kill off broad leaved weed, the grassy weed of wheat paddock and rice terrace, and to Target crops safety, with single dose phase
Have the mechanism of action unique than, Herbicidal combinations of the present invention, there is that dosage is few, weeding is general more extensively, and the lasting period is longer, more ring
The obvious advantages such as guarantor.So research and development and popularization of the invention have great social effect and environment protection significance.
