Abstract
The invention belongs to the field of pesticides, and provides a mixed herbicide containing topramezone and simazine, and application thereof. The mixed herbicide contains active ingredients of topramezone and simazine in the weight ratio of 1:60-900:1. The mixed herbicide can be applied to the weeding of corn field, and particularly has significant effect in controlling germinated or nearly germinated Gramineae, Cyperaceae and broadleaf weeds. Compared to a single dosage, the herbicide of the invention, on the promise of improving the drug effect, delays weed resistance, widens herbicidal spectrum, and has long duration and security to corn.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of mixed herbicide that comprises benzene azoles humulone and Simanex and shouldWith.
Background technology
Whole nation corn weeds have 22 sections, and 38 belong to, 43 kinds, wherein to the larger weeds of corn harm mainly contain lady's-grass,Barnyard grass, purslane, Amaranthus retroflexus, field bindweed, lamb's-quarters, india lovegrass, green dog tail etc. are larger on corn seedling impact, mainTo make that milpa is short and small, bar is thin, leaf is yellow, seriously can the underproduction reach 35%. Therefore, cornfield weeding is becomeSteps necessary in Maize Production. But each weeds differs to the tolerance of herbicide, single use is a certainHerbicide is difficult to efficient, the safe weed control of carrying out. Therefore,, for improving preventive effect, complex weedicide becomes thisOne of emphasis of area research.
Benzene azoles humulone (topramezone), has another name called: benzene pyrazoles humulone, chemical name: [3-(4,5-dihydro-1,2-oxazole-3-yl)-4-formoxyl 0-tolyl] (5-hydroxyl-1-methyl-pyrazol-4-yl) ketone. Benzene azoles humulone is wide spectrum herbicide after seedling,Can effectively prevent and kill off milpa annual gramineae and broad leaved weed, sedge weed. Corn postemergence application, susceptible weedsAbsorb by blade, and conduction up and down in plant, in 2-5 days, there is albefaction poisoning symptom, growing point,The poisoning symptom of internode, blade and vein is the most obvious, and organizing of albefaction is downright bad gradually, and stops growing very soon, a littleDead in several weeks. Benzene azoles humulone has certain activity to not being unearthed or being about to unearthed weeds, but activity is subject to its concentration and soilThe impact of earth content of organic matter height.
Simanex (simazine), chemical name: 2-is chloro-4, and two (ethylamino-) s-triazine of 6-, store 2 years under normal temperature,Active constituent content is substantially constant, is mainly used in corn, jowar, sugarcane, tea place and orchard and prevents and kill off green bristlegrass, thrushAnnual broadleaf weed and the part grassy weeds such as grass, nutgrass flatsedge, three-coloured amaranth, lamb's-quarters, efficiency time is long. The use of SimanexDose is subject to the soil texture, and the content of organic matter, temperature height affect very large. General temperature high organic content is low, sandySoil consumption is few, good drug efficacy, but also easily produce poisoning. It is high that otherwise consumption is wanted.
Summary of the invention
The object of the invention is to provide a kind of mixed herbicide of highly effective and safe for preventing and kill off corn field weeds.
1. the invention provides a kind of mixed herbicide that comprises benzene azoles humulone and Simanex, this mixed herbicide is with benzene azoles humuloneWith Simanex be main active ingredient; Wherein, the mass ratio of benzene azoles humulone and Simanex is 1: 60-900: 1.
2. above-mentioned 1 mixed herbicide providing, wherein, the mass ratio of benzene azoles humulone and Simanex is 1: 10 1: 1.
3. above-mentioned 1 mixed herbicide providing, wherein, the mass ratio of benzene azoles humulone and Simanex is 1: 10-2: 1.
4. above-mentioned 1 mixed herbicide providing, wherein, the mass ratio of benzene azoles humulone and Simanex is 1: 3-8: 1.
5. the mixed herbicide that above-mentioned 1-4 any one provides, wherein, the benzene azoles humulone of benzene azoles humulone and Simanex and westGross mass mass percent in herbicide in agate Tianjin is 15%-80%.
6. above-mentioned 5 mixed herbicides that provide, wherein, the benzene azoles humulone of benzene azoles humulone and Simanex and the total matter of SimanexAmount mass percent in herbicide is 15%-60%.
7. above-mentioned 5 mixed herbicides that provide, wherein, the benzene azoles humulone of benzene azoles humulone and Simanex and the total matter of SimanexAmount mass percent in herbicide is 40%-80%.
8. above-mentioned 5 mixed herbicides that provide, wherein, wherein, this mixed herbicide taking benzene azoles humulone and Simanex asThe auxiliary agent allowing on main active ingredient and agricultural chemicals is mixed with any one formulation.
Any one formulation allowing on agricultural chemicals comprises conventional surfactants, thickener, solvent or solid packing. TableSurface-active agent can, for to demonstrate surfactant gelation or swellability in water, can be fatty acid ester, alkaneBase ether, acetylenediol, polyoxy acetylene castor-oil plant wet goods non-ionic surface active agent, as APES, polyoxyThe anionic surfaces such as the rare block compound of ethene polyoxy third or alkyl sulfate, lignosulfonates, soap are livedProperty agent, as cation forms such as sodium lignin sulfonate, neopelex or hydrochloric acid lauryl amine, acetic acid stearylaminesSurface-active agent. Above surfactant can one or more mix use. Thickener, as white carbon, is not limit especiallySystem. Solvent can be inert liquid carrier, such as monohydric alcohol, polyalcohol, ketone, ethers, fat hydrocarbon, haloHydro carbons etc., as vegetable oil; Above inert liquid carrier can one or more mix use. Solid carrier can be skySo mineral matter class, inorganic salts, starch, celluloses etc., as ammonium sulfate, diatomite, kaolin; Above solid carriesBody can one or more mix use.
9. above-mentioned 8 mixed herbicides that provide, wherein, the formulation of herbicide is aqueous suspension agent, oil-suspending agent, wettableProperty pulvis, water dispersible granules.
The present invention also provide mixed herbicide described in above-mentioned 1-9 any one prevent and kill off various standing grain in corn field thisApplication in section, Cyperaceae and broad leaved weed. .
Beneficial effect:
1, activity of weeding is high. Benzene azoles humulone is mainly absorbed by root and young stem, leaf, in plant body Xiang Ding, conduct to baseTo separate living tissue, by suppressing the 4-medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (4HPPD) in plastoquinone biosynthesis,Remote-effects carotenoid synthetic, disturbs the synthetic and function of chloroplaset, finally cause serious albefaction (due toChlorophyllous degraded). Simanex is after root absorption medicament, to work in suppressing weed seed germination process. NamelySay, herbicidal composition of the present invention can kill weeds by two kinds of different approaches, can greatly improve and removeThe removing activity of grass agent. That is to say, herbicidal composition of the present invention can kill by two kinds of different approachesWeeds, can greatly improve the removing activity of herbicide.
2, herbicidal spectrum is wide, and the lasting period is long. Benzene azoles humulone and tritosulfuron are all broad spectrum weeding agent, and both are mixedAfter closing, action compensating, herbicidal spectrum is wider, and the lasting period of medicament is longer. Through field control effectiveness test, the two is multipleJoin the rear preventive effect that sedge weed, grassy weed and broad leaved weed is all had to obvious enhancing, preventive effect all higher than90%, even after 40 days, the two does not still decline to the preventive effect of weeds.
3, delay Weed Resistance. Because weeds easily produce resistance to herbicide single dose, and in herbicide of the present inventionContain tritosulfuron, make medicament can effectively prevent the weeds except easy generation resistance, reduced the anti-of weedsThe property of medicine, has extended service life of medicament.
Therefore, mixed herbicide of the present invention can, in the middle application of cornfield weeding, particularly prevented and kill off various standing grainIn undergraduate course, Cyperaceae and broad leaved weed, apply.
