The invention discloses a kind of Herbicidal combinations containing topramezone and application thereof, this Herbicidal combinations is made up of topramezone, nicosulfuron and amicarbazone and dispersant, emulsifying agent, wetting agent, thickening agent, antifreezing agent and disperse medium, and the dosage form that can be made into is for dispersibling oil-suspending agent.Three kinds of active component compound has obvious potentiation, decreases Pesticide use amount, reduces cost and the pollution to environment, and the application of compositions can delay the Drug resistance of corn field weed, expand and prevent and kill off spectrum.

Description

A kind of Herbicidal combinations containing topramezone and application thereof
Technical field
The present invention relates to technical field of pesticide, particularly relate to a kind of Herbicidal combinations containing topramezone and application thereof.
Background technology
Topramezone is a kind of contact killing type selective herbicide, under conditions of having light, in chlcrophyll biosynthesis process In, caused the accumulation of poisonous intermedium by suppression proporphyrinogen oxidase, thus destroy the cell membrane of weeds, make blade rapid Withered, dead, carfentrazoneethyl is i.e. absorbed by plant leaf blade in 15 minutes after spray medicine, and it is not drenched with rain affects, miscellaneous after 3-4 hour Grass occurs as soon as poisoning symptom, and 2-4 days dead.
Nicosulfuron can prevent and kill off annual and perennial grassy weed and part broad leaved weed.Test shows, to medicine The weeds that sensitivity is strong have grass, Herba Setariae Viridis, wild oat, Amaranthus retroflexus；The medium weeds of sensitivity have Ben Shi knotweed, rule grass, Dens Equi Herba Amaranthi tricoloris, Herba monochoriae vaginalis, Herba Xanthii and Herba Abutili, dried tuber；The poor weeds of sensitivity mainly have Herba chenopodii, Herba Solani Nigri, Tradescantia albiflora, Fructus Kochiae and weasel hemp nettle.
Amicarbazone belongs to triazolineone herbicide, efficient, by suppression to broad leaved weeds such as Chenopodiaceae, Amaranthaceae, Tong fiber crops Single-chip microcomputer dual oxide enzyme and destroy chlorophyllous formation, the weeds chlorosis that causes being injured is withered.
Herbicide single dose preventing and treating grass is to single, and is used alone farmland weed and develops immunity to drugs, therefore by three kinds of herbicides Science assembles, thus expands weed control spectrum, reduces times for spraying and dosage, is current rice district urgent problem.
Summary of the invention
The present invention provides a kind of Herbicidal combinations containing topramezone, and three kinds of active component compound has obvious potentiation work With, decreasing Pesticide use amount, reduce cost and the pollution to environment, the application of compositions can delay the anti-of corn field weed The property of medicine, expands and prevents and kill off spectrum.
Present invention simultaneously relates to the application in preventing and treating corn field weed of this Herbicidal combinations.
The present invention is achieved by the following technical solutions:
A kind of Herbicidal combinations containing topramezone, the active component of described compositions is by topramezone, nicosulfuron and ammonia azoles Oxadiazon is 1-50:1-20:1-70 composition according to mass ratio.
Preferably, the mass ratio of topramezone, nicosulfuron and amicarbazone is 1-10:1-10:10-30.
It is highly preferred that the mass ratio of topramezone, nicosulfuron and amicarbazone is 2.5:4.5:24.
Can be configured to any dosage form agriculturally allowed during reality of the present invention application, preferential preparation formulation is to dispersible oil Suspending agent.
For dosage form for dispersibling oil-suspending agent, it is made up of following mass percent: active component 20-40%, dispersant 2- 6%, emulsifying agent 5-15%, wetting agent 1-3%, thickening agent 1-5%, antifreezing agent 3-8%, disperse medium surplus.
Preferably, it is made up of the component of following mass percent: active component 31%, dispersant 4%, emulsifying agent 8%, moistening Agent 2%, thickening agent 2%, antifreezing agent 5%, disperse medium surplus.
Wherein, dispersant is mixed with calcium lignosulfonate 1:1 in mass ratio by polycarboxylate sodium, and emulsifying agent is for telling Temperature-60#, wetting agent is sodium lauryl sulphate, and thickening agent is that bentonite mixes with xanthan gum 1:1 in mass ratio, antifreeze Agent is propylene glycol, and disperse medium is methylated vegetable oil.
By dispersant, emulsifying agent, wetting agent, thickening agent, antifreezing agent, disperse medium in above-mentioned formula, through high speed shear Mix homogeneously, adds topramezone, nicosulfuron and amicarbazone, and high speed shear is disperseed, and prepares containing benzene with after sand mill sand milling Azoles oxadiazon dispersible oil-suspending agent.
Herbicidal combinations described above application in preventing and treating corn field weed, the weeds that can prevent and treat have Herba Digitariae, Canis familiaris L. tail Grass, Herba Portulacae, Herba Xanthii, Herba chenopodii etc..
After different herbicidal activity component mixing, each active component is due to composition, structure, the difference of physicochemical property so that each Synergy between active component is usually expressed as potentiation, summation action or antagonism.So-called potentiation is exactly Cooperating effect between different material, its effect produced is more than the sum total of each composition effect；And summation action is exactly it The effect produced is equal to the sum total of each composition effect；Antagonism refers to, when two kinds of materials act on living organism, create
A kind of material disturbs the effect of another material, or the effect of interfering with an opponent each other, makes general effect decline Phenomenon.
The present invention make use of topramezone, nicosulfuron and the not same-action machine of three kinds of herbicides of amicarbazone dexterously Reason, compounds three, has reached potentiation.
There is the most serious corn field for broad leaved weed in the Herbicidal combinations of the present invention, active component amicarbazone and Topramezone has been greatly reinforced the prevention effect to broad leaved weed, and on this basis, nicosulfuron then can be to major part grass family Weeds effectively prevent and treat.
Beneficial effects of the present invention:
1. the Herbicidal combinations that the present invention provides, component is reasonable, and herbicidal effect is good, and drug cost is low, and its activity and weeding are imitated Fruit is not the simple superposition of each composition activity, but has significant potentiation, can expand control of weeds spectrum, to crop safety Good, meet the security requirement of pesticidal preparations, decrease times for spraying simultaneously, reduce drug cost.
2. the Herbicidal combinations that the present invention provides, three kinds of active component mechanism of action are not quite identical, can overcome long-term Single use easily produces the shortcoming of resistance, delaying drug resistance, extends the service life of medicament, and the comprehensive control to Weed Resistance has Significance.
3. the present composition can be made into and dispersibles oil-suspending agent, and the selection of adjuvant and dosage form improves drug effect.
