Abstract
The invention discloses a corn field efficacy enhancement weed killing combination containing thiencarbazone-methyl, mesotrione and atrazine. According to the combination, the weight ratio of thiencarbazone-methyl, mesotrione to atrazine is 1:1 to 15:20 to 100. By performing ternary compounding to thiencarbazone-methyl, mesotrione and atrazine, the obtained novel combination can effectively solve the defect when thiencarbazone-methyl or mesotrione is singly adopted, enlarges the herbicide controlling spectrum to weeds, can basically solve corn field weeds when applied one time, saves labor and time, and meanwhile has certain effects on increasing both production and income of corn. In addition, the usage dosage of pesticide is reduced, the adverse effect on ecological environment by pesticide is lowered, and the generation of drug resistance is delayed.
Description
Technical field
The present invention relates to a kind of composition pesticide, a kind ofly specifically contain that thiophene ketone sulphur is grand, the corn field Herbicidal synergistic ternary recompounded composite of mesotrione and atrazine.
Background technology
Thiophene ketone sulphur is grand, chemical name: methyl 4-[(4,5-dihydro-3-methoxyl group-4-methyl-5-oxo-1H-1,2,4-triazol-1-yl) carbonyl sulfonamide]-5-methylthiophene-3-carboxylic acid, ethyl ester, structural formula is:
This weed killer herbicide is interior absorption medicament, can cross root and leaf absorption, has and tags and residual herbicidal effect, can effectively prevent and kill off corn field grassy weed and broad leaved weed.
Mesotrione, has another name called mesotrione, chemical name: 2-(4-mesyl 2-nitro-benzoyl) thiacyclohexane-1,3-diketone, structural formula is:
This weed killer herbicide is corn field Common Herbicides, with its broad weed-killing spectrum, active high, miscibilty strong, to succession crop safety, use flexibly, Environmental compatibility is strong etc., and feature has compared with great development and is worth and promotes the use of preferably prospect in China.
Atrazine, has another name called atrazine, is corn field Common Herbicides, to corn safety, for soil treatment before bud, can effectively prevent and kill off multiple corn field weed.
The present invention is grand to thiophene ketone sulphur, the mixture of mesotrione and atrazine conducts in-depth research, on the basis of formula indoor screening test and field medicine effect test, find that thiophene ketone sulphur is grand, mesotrione and atrazine show obvious synergistic effect to corn field weed within the scope of certain mixed ratio.Thiophene ketone sulphur is grand, the mixture of mesotrione and atrazine and the invention in corn field application there is no report at present both at home and abroad.
Summary of the invention
The object of the invention has been to provide a kind of synergistic herbicidal compositions, said composition is undertaken composite by grand thiophene ketone sulphur, mesotrione and atrazine, can disposablely prevent and kill off weeds all between corn field, expand that thiophene ketone sulphur is grand, the restriction of mesotrione or atrazine herbicide spectrum separately, improve that thiophene ketone sulphur is grand, mesotrione and the herbicide speed of atrazine to grass family, broad-leaved section weeds.The discovery that the present invention is surprised, the new compositions obtaining has been obtained gain effect on the malignant weed of control of maize field, significantly reduces the amount of the required active component of control of weeds, and the safety to crop.
Be below the technical solution used in the present invention:
The invention provides a kind ofly contain that thiophene ketone sulphur is grand, the corn field Synergistic herbicide compositions of mesotrione and atrazine, it is characterized in that: comprise that three kinds of effective ingredient thiophene ketone sulphur is grand, mesotrione and atrazine, thiophene ketone sulphur is grand, mesotrione and the ratio of weight and number of atrazine in composition are 1～100:1～100:1～100, preferred weight portion rate is 1:1～15:20～100, and particularly preferably ratio of weight and number is 1:1～15:20～60.

biological Examples
When the effect of active compound combinations exceedes the summation of the effect when each reactive compound is used separately, there is synergistic function.The predictive role of the particular combination of three kinds of reactive compounds can be used " Colby formula " (referring to S.R. Colby, " Calculating Synergistic and Antagonistic Responses of Herbicide Combinations ", Weeds 1967,15,20-22) calculate as follows: if
A is the activity when using consumption for mg/ha or the concentration reactive compound A that is mppm;
B is the activity when using consumption for ng/ha or the concentration reactive compound B that is nppm, is expressed as the percentage that accounts for untreated control; C is the activity when using consumption for hg/ha or the concentration reactive compound C that is hppm, is expressed as the percentage that accounts for untreated control; E is to be m when using consumption, n, and h g/ha or concentration are m, n, the reactive compound A of hppm, expection activity when B and C,
（N=3）
If the activity of actual observation (O) is greater than expection active (E), said composition has synergistic effect so.
Inventor is by a large amount of screening tests, the different proportionings of, mesotrione grand to thiophene ketone sulphur and atrazine have carried out test and preventive effect analysis a large amount of, discovery is in certain ratio range, the Herbicidal combinations obtaining has synergistic effect, and be not only the simple addition of three kinds of medicaments, be illustrated with following biologicall test example.
