Abstract
The invention belongs to the technical field of pesticides and provides mixed herbicide containing topramezone and clopyralid and application thereof. According to the mixed herbicide, topramezone and clopyralid are used as main active ingredients, and the mass ratio of topramezone to clopyralid is in a range of 1:1 to 900:1. The application of the mixed herbicide in weeding in corn fields, in particular the application in preventing and killing various gramineous, cyperaceae and broad-leaved weeds which have come up or are about to come up, is remarkable in effect. Compared with a single agent, the herbicide has the advantages that on the premise that the herbicide effect is improved, the weed resistance is retarded, the weeding range is wide, the lasting period is long, and the herbicide is safe to corn.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of mixed herbicide and the application thereof that comprise benzene azoles humulone and clopyralid.
Background technology
Corn is the important cereal crops of China, and corn field weed kind reaches kind more than 30, and weed killer herbicide conventional at present comprises acetamide-group herbicides, triazine herbicide, phenoxy carboxylic acid herbicides, sulfonylurea herbicide and other weed killer herbicide.The shortcomings such as a certain weed killer herbicide of single use has herbicide resistance, crop key, herbicidal spectrum is narrow, the residence time is long, therefore, complex weedicide is the direction of current research.
Benzene azoles humulone (topramezone); have another name called: benzene pyrazoles humulone; chemical name chemical name: [3-(4; 5-dihydro-1; 2-oxazole-3-base)-4-formoxyl 0-tolyl] (5-hydroxyl-1-methyl-pyrazol-4-yl) ketone; be novel hydroxyl phenylacetone acid esters dual oxide enzyme inhibitor (HPPD) weed killer herbicide, be wide spectrum herbicide after seedling, effectively can prevent and kill off corn field annual gramineae and broad leaved weed, sedge weed.Corn postemergence application, absorbed by root and seedling, leaf, in plant Xiang Ding, be transmitted to meristematic tissue to base, cause the susceptible weeds albefaction of germinateing, with growth inhibition, under photosynthesis, its damage symptoms is like chlorotic necrosis, responsive target weeds 2 ~ 5d Inner bleaching symptom after treatment, in 14d, plant is dead, have certain activity, but activity affects to not being unearthed or being about to unearthed weeds by its concentration and soil organic matter content height, have report, benzene azoles humulone is poor to broad leaved weed herbicidal effect in certain areas simultaneously.
Clopyralid is a kind of auxin of Prof. Du Yucang, its chemical constitution and many natural auxins similar, but in the tissue of plant, there is better persistence.It carries out absorbing then conducting in plant corpus, so its conductive performance is stronger mainly through the root of plant and leaf.After weeds dispenser, it is by the blade of plant or root absorption, moves up and down and be transmitted to rapidly whole plant in plant corpus.
Summary of the invention
The object of this invention is to provide one corn field mixed herbicide safely and effectively.
Another object of the present invention is to provide the application of this weed killer herbicide in cornfield weeding.
1. the invention provides a kind of mixed herbicide comprising benzene azoles humulone and clopyralid, this mixed herbicide with benzene azoles humulone and clopyralid for principle active component; Wherein, the mass ratio of benzene azoles humulone and clopyralid is 1: 1-900: 1.
2. above-mentioned 1 mixed herbicide provided, wherein, the mass ratio of benzene azoles humulone and clopyralid is 10: 1-45: 1.
3. above-mentioned 1 mixed herbicide provided, wherein, the mass ratio of benzene azoles humulone and clopyralid is 25: 1-45: 1.
4. above-mentioned 1 mixed herbicide provided, wherein, the mass ratio of benzene azoles humulone and clopyralid is 30: 1-45: 1.
5. the mixed herbicide described in above-mentioned any one of 1-4, wherein, the benzene azoles humulone of benzene azoles humulone and clopyralid and clopyralid gross mass mass percent in weed killer herbicide is 20%-85%.
6. the mixed herbicide described in above-mentioned 5, wherein, the benzene azoles humulone of benzene azoles humulone and clopyralid and clopyralid gross mass mass percent in weed killer herbicide is 20%-65%.
7. the mixed herbicide described in above-mentioned 5, wherein, the benzene azoles humulone of benzene azoles humulone and clopyralid and clopyralid gross mass mass percent in weed killer herbicide is 45%-80%.
8. the mixed herbicide described in above-mentioned 5, wherein, this mixed herbicide with benzene azoles humulone and clopyralid for the auxiliary agent that principle active component and agricultural chemicals allow is mixed with any one formulation.
9. the mixed herbicide described in above-mentioned 7, wherein, the formulation of weed killer herbicide is oil-suspending agent, aqueous suspension agent, wetting powder, water dispersible granules.
Any one formulation that agricultural chemicals allows comprises conventional surfactants, thickener, solvent or solid packing.Surfactant can in water, demonstrate gelation or the surfactant of swellability, can be fatty acid ester, alkyl ether, acetylenediol, polyoxy acetylene castor-oil plant wet goods non-ionic surface active agent, as anion surfactants such as alkylphenol polyoxyethylene, the rare block compound of polyoxyethylene polyoxy third or alkyl sulfate, lignosulfonates, soaps, as cationic surfactants such as sodium lignin sulfonate, neopelex or laurylamine hydrochloride, acetic acid stearylamines.Above surfactant can one or more be used in combination.Thickener, as white carbon, is not particularly limited.Solvent can be inert liquid carrier, such as monohydric alcohol, polyalcohol, ketone, ethers, fat hydrocarbon, halogenated hydrocarbon etc., as vegetable oil; Above inert liquid carrier can one or more be used in combination.Solid carrier can be natural mineral matter class, inorganic salts, starch, cellulose etc., as ammonium sulfate, diatomite, kaolin; Above solid carrier can one or more be used in combination.
9. the mixed herbicide described in above-mentioned 7, wherein, the formulation of weed killer herbicide is oil-suspending agent, aqueous suspension agent, wetting powder, water dispersible granules.
10. the present invention also provides the mixed herbicide described in above-mentioned any one of 1-9 preventing and kill off the application in various grass family, sedge family and broad leaved weed in corn field.
Beneficial effect:
1, activity of weeding is high.Benzene azoles humulone absorbs primarily of root and young stem, leaf, in plant body Xiang Ding, be transmitted to meristematic tissue to base, by suppressing 4-medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (4HPPD) in plastoquinone biosynthesis, the synthesis of remote-effects carotenoid, the synthesis of interference chloroplast and function, finally cause serious albefaction (due to chlorophyllous degraded).All can use after seedling before clopyralid seedling, carry out absorbing then conducting in plant corpus, so its conductive performance is stronger mainly through the root of plant and leaf.After weeds dispenser, it is by the blade of plant or root absorption, moves up and down and be transmitted to rapidly whole plant in plant corpus.That is, herbicidal composition of the present invention can kill weeds by two kinds of different approaches, greatly can improve the removing activity of weed killer herbicide.
2, herbicidal spectrum is wide, and the lasting period is long.Benzene azoles humulone and clopyralid are all broad spectrum weeding agent, and after both mixing, action compensating, herbicidal spectrum is wider.Through field control effectiveness test, can find, benzene azoles humulone and clopyralid composite after mixed herbicide to the preventive effect of weeds all higher than being used alone wherein a kind of weed killer herbicide, even if after 40 days, herbicidal effect does not reduce yet.
3, Weed Resistance is delayed.Because weeds easily produce resistance to weed killer herbicide single dose, and containing clopyralid in weed killer herbicide of the present invention, enabling the medicament anti-weeds except easily producing resistance effectively, reducing resistance weed, extending the service life of medicament.
Therefore, mixed herbicide of the present invention can be applied in cornfield weeding, is particularly preventing and kill off unearthed or is being about to apply in unearthed various grass family, sedge family and broad leaved weed.
