Abstract
The present invention relates to the herbicidal composition containing dichloroquinoline humulone and diflufenican, the Herbicidal combinations have synergistic function, wherein, the weight ratio of dichloroquinoline humulone and diflufenican is 1:60‑50:1.
Description
Technical field
The invention belongs to mixture of herbicides fields, and in particular to be a kind of to contain dichloroquinoline humulone and diflufenican
Herbicidal combinations, the composition herbicidal effect is good, the lasting period is long.
Background technology
Dichloroquinoline humulone, chemical name 2-（3,7- dichloroquinoline -8- bases）Carbonyl-cyclohexanone -1,3- diketone, CAS
Number for 1350901-36-8, it is the new herbicides of China's independent research, mainly absorbs to prevent and kill off by weeds root, stem, leaf
The especially more difficult at present barnyard grass prevented and kill off of gramineous crop, green bristlegrass, lady's-grass and a variety of broad leaved weeds, after weeds dispenser,
It by blade or root absorption, is transferred up and down in plant, passes to entire plant rapidly, be HPPD inhibitor, effect is special
Weeds root during point, leaf Assimilation and conductivity and work, after susceptible weeds absorb this medicine, by inhibiting p-hydroxybenzene pyruvic acid (HPP) ester double
The synthesis of oxidizing ferment leads to the accumulation of tyrosine, makes the biosynthesis block of plastoquinone and tocopherol, and then influences carotenoid
Biosynthesis, weeds occur dead after albefaction.
Diflufenican（Diflufenican), chemical name：N- (2,4 difluorobenzene bases）- 2- [(3- trifluoromethyls）Benzene
Oxygroup] -3- pyridine anilides, belong to herxheimer-liked reaction inhibitor, absorb carotenoid in the weeds plant of medicament
Content declines, and leads to Destruction of Chlorophyll and cell rupture, and weeds show as young shoot decoloration or white, and last plant wilt is dead.
It is mainly used for corn and soybean and wheatland prevents and kill off a variety of annual gramineous weeds and certain broad leaved weeds.Especially to be clearvers,
The removal effect of Veronica is apparent.
At present, the herbicide herbicide controlling spectrum of single active ingredient is limited, and exclusive use can not effectively control weeds
Occur, furthermore, the herbicide of single kind, which is used for a long time, can lead to the generation of herbicide resistance.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide a kind of efficient, low toxicity, low cost, lasting effect are good
Composition, be conducive to the integrated treatment of crop weeds, the composition active constituent includes dichloroquinoline humulone and pyrrole fluorine acyl
Careless amine.
The herbicidal composition of the present invention may include other ingredients, such as selected from herbicide, insecticide, fungicide and safety
It common additive and/or formulation auxiliary agents or can be used together with which in the pesticide activity component of agent and/or plant protection.
The Herbicidal combination of the present invention has synergistic function so that the dosage of each active constituent reduces, is identical
Drug effect enhancing under dosage, it is however generally that, the weight ratio of dichloroquinoline humulone and diflufenican is 1 in composition:60-60:
1, preferably 1:30-30:1, more preferably 1:10-10：1.
The content of active constituent can change, such as weight percent in a wider scope in the Herbicidal combinations of the present invention
Content is 1-90%, preferably 10-70%, more preferably 20-50%.
The Herbicidal combinations of the present invention can be prepared by a conventional method with auxiliary element conventional in Pesticide formulation
Into arbitrary possible conventional formulation：Wettable powder, water dispersible granules, aqueous emulsion, microemulsion, suspending agent, soluble liquid, kind
Clothing suspending agent etc..
Further, it is miscellaneous to can be used for preventing and kill off grassy weed in various crop, broad-leaved to Herbicidal combinations of the invention
Grass, preferably sedge weed, barnyard grass.
The present invention Herbicidal combinations frequency of use and usage amount with crops, weeds, weather condition and it is small change,
It can achieve the purpose that effectively to prevent by using suitable dosage.
Compared with prior art, beneficial effects of the present invention are：
1st, the Herbicidal combinations have apparent synergistic function, can significantly improve preventive effect, extend
The protection period of medicament reduces Pesticide use amount and the risk to environment, meets the demand of " pesticide zero growth rate "；
2nd, safe, herbicidal composition of the invention also has very high under the premise of drug effect is improved, to crops
Safety.

2nd, biological Examples
1st, Application Example 1：Dichloroquinoline humulone and the life of diflufenican and its mixture composition to paddy field weed
Object active determination test is reported
Experiment purpose：Dichloroquinoline humulone and diflufenican and its different mixture groups are determined under the conditions of greenhouse pot culture
Close herbicidal effect of the object to barnyard grass（7 days after medicine）, and its synergy is had rated, the formulation development and pesticide for Mixed Pharmacy are stepped on
Remember that field control effectiveness test provides scientific basis.
For trying target：Rice barnyard grass
If the mixture activity value of observation has been more than the form adduction that test value is administered alone, then they equally also surpass
Cross the predicted value according to Colby, the predicted value of the Colby:
E0=X+Y-XY/100
In formula, X, Y are respectively the component dichloroquinoline humulone or diflufenican when dosage is a or b active constituents/hectare
Effect by weight percentage；E0Expection when for dichloroquinoline humulone and diflufenican dosage being a+b in terms of percentage
Value when the observed value of herbicidal composition is more than the desired value according to Colby, that is, thinks dichloroquinoline humulone or pyrrole fluorine acyl grass
The compounding of amine shows synergistic function.Result of the test is shown in Table 1.
Evaluating drug effect：Dichloroquinoline humulone is shown in Table 1 with diflufenican and its mixture composition to the measurement result of rice barnyard grass,
Dichloroquinoline humulone and diflufenican are 1 it can be seen from 1 result of table:60-50：The preventive effect of rice barnyard grass is showed in the range of 1
Go out synergistic effect.In scope of medication, the apparent poisoning of rice is not observed and is generated.
2nd, field control effectiveness test
This, which is tested, is located at Fushan City, Guangdong Province suburb San Shui towns, red earth, PH6.0, organic matter 1.3%, medium fertility,
Water pours that condition is good, and weather is fine, 26-32 DEG C of temperature, and venting water in field first before spray makes weeds expose the surface, connects after spray
Continuous dry field 5 days, then 3-5 centimetres of holding shallow water 7 days, finally restores normal field management；Rice varieties are accounted for for Foshan oil（Hybridization
Rice）, rice is in the 3-4 leaf phases during spray, and weeds are in the 3-5 leaf phases, and field main weeds type is rice barnyard grass（Coverage accounts for entirely
Weed community 75%）.67 square metres of plot area, is repeated 4 times, random district's groups arrangement.15 days after medicine, investigate within 30 days and prevent
Effect.Result of the test is shown in Table 2.
Field control effectiveness test result shows dichloroquinoline humulone and diflufenican mixture preparation, and process is prevented to barnyard grass
In, lasting effect and quick-acting are preferable, and in dosage less than in the case of single dose, preventive effect is preferable, and has preferable effect of increasing production,
In scope of medication, to crop safety, no poisoning is worthy of popularization.
The illustrative embodiments that above-described embodiment uses only for illustrating inventive principle, however the present invention is not limited only to
This, those skilled in the art can make various improvement and change in the case where not departing from real situation of the present invention, these improve and become
More also belong to protection scope of the present invention.
