Abstract
The invention discloses a herbicide taking methoxone isooctyl and nicosulfuron as major active ingredients special for corn fields, which is dispersible oil-based suspension, and is prepared, based on 100 percent, from the following raw materials and aids in percentage by weight: 20 to 50 percent of methoxone isooctyl, 2 to 20 percent of nicosulfuron, 1 to 10 percent of polyoxyethylene castor oil, one, two, three, four or five of 1 to 10 percent of sorbitan monooleate, 1 to 10 percent of alkylphenol ethoxylates, 0.1 to 2 percent of xanthan gum and 2 to 5 percent of magnesium aluminum silicate, one, two, three, four, five or six of an emulsifier, a stabilizer, a dispersant, a wetting agent, a spreader, a synergist and an antifreeze agent in conventional herbicide aids, and the balance of formic ester oil. The methoxone isooctyl nicosulfuron dispersible oil-based suspension is prepared by stirring, mixing, dissolving, cutting, grinding and regulating the raw materials and the aids. The herbicide reduces the dominant or recessive phytotoxicity of the nicosulfuron to corn aftercrop wheat and greatly improves safety in herbicide application.
Description
Technical field
But the present invention relates to a kind of is the dispersed oil suspending agent of main active ingredient with methoxone isooctyl and nicosulfuron, is herbicides special behind a kind of environment amenable efficient fast-acting type corn field seedling, belongs to agricultural technology field.
Technical background
Current, the weeds of harm corn mainly contain descurainia sophia (l.) webb ex prantl, shepherd's purse, clearvers, Veronica, chickweed, the rhizome of nutgrass flatsedge, convexutricle sedge herb, Monochoria vaginalis, wild arrowhead and acalypha copperleaf, pivot and broad-leaved and grassy weed such as hold, and spring corn and summer corn all are injured seriously.At present, for the control of corn field weed, mainly based on the sulfonylurea herbicide after seedling, spray in the corn 4-6 leaf phase, especially nicosulfuron is the most representative.But this kind weed killer herbicide is applied for many years in China, and each corn main producing region has had the resistant weed biological strain to produce, and routine administration amount preventive effect descends, and certainly will will strengthen dosage in order to guarantee preventive effect.Like this, very easily to producing a poisoning when the stubble corn, back stubble wheat also in various degree show dominance or stealthy poisoning, drug safety can not guarantee.Can effectively not substitute on the basis of nicosulfuron still there being other weed killer herbicide new varieties, for addressing this problem, having occurred in succession on the market with the nicosulfuron is main component, cooperates compositions such as atrazine, mcpa sodium to mix and uses, and has obtained certain good effect.But, long-term a large amount of serious polluted underground water resources of meeting of using of atrazine, mcpa sodium exists serious soup drift and sodium salt deposited phenomenon, very easily cause soil compaction, salinization of soil and fertility to descend, the annual incident that causes non-target to do the deposits yields poisoning because of the soup drift also happens occasionally, and the environmental friendliness degree is all undesirable.Therefore, press for a kind of new environment amenable effective ingredient of introducing and nicosulfuron and use with weeds behind the control corn field seedling, very coincidence is, the different monooctyl ester of methoxone involved in the present invention has then well solved the problems referred to above.
Summary of the invention
Technical problem to be solved by this invention is, but a kind of environment amenable efficient fast-acting type corn field herbicide after seedling---the different monooctyl ester nicosulfuron of methoxone dispersed oil suspending agent is provided, and it is to the succession crop of corn---wheat shows high safety simultaneously.
Its technical scheme is: a kind of with the different monooctyl ester of methoxone and the nicosulfuron herbicide specially for corn field as main active ingredient, it is characterized in that: make: the different monooctyl ester 10～50% of methoxone by following raw materials in percentage by weight and auxiliary agent, nicosulfuron 2～20% and castor oil polyoxyethylene ether 1～10%, oleic acid acid pears alcohol ester 1～10%, alkylphenol polyoxyethylene 1～10%, xanthans 0.1～2%, a kind of among the Magnesiumaluminumsilicate 2-5%, two kinds, three kinds, four kinds or five kinds, and the emulsifier in the conventional auxiliary agent of weedicide, stabilizing agent, dispersant, wetting agent, spreader-sticker, synergist, a kind of in the antifreezing agent, two kinds, three kinds, four kinds, five kinds or six kinds, formicester oil complements to 100%;
Above-mentioned supplementary material behind the mixed dissolution, through shearing, grind and adjusting, finally makes composition involved in the present invention under stirring, its preparation type is: but the dispersed oil suspending agent.
Involved in the present invention a kind of with the different monooctyl ester of methoxone and the nicosulfuron herbicide specially for corn field as main active ingredient, its good effect has mainly showed:
1, environmentally friendly: under the prior art condition, the corn field postemergence weed control is mainly based on nicosulfuron, the single agent weed killer herbicide of this kind has been applied for many years in China, each corn main producing region has had the resistant weed biological strain to produce, routine administration amount preventive effect descends, in order to guarantee that preventive effect certainly will will strengthen dosage or introduce a kind of new active ingredient, the active ingredient that the present invention introduced---the different monooctyl ester of methoxone can effectively promote the preventive effect of nicosulfuron to weeds, for reaching same herbicidal effect, can reduce the consumption of nicosulfuron in a large number.Simultaneously, because of itself being lipoid substance, do not possess drift characteristic, catabolite is also nontoxic, harmless, thereby high to the friendliness of environment, solved well that nicosulfuron and atrazine, mcpa sodium etc. are used with and the stress problems that increased environment.
2, efficient, quick-acting: though nicosulfuron possesses broad weed-killing spectrum, characteristics such as the drug effect phase is long, it is invalid substantially that it malignant weed such as holds for the rhizome of nutgrass flatsedge, wild arrowhead, acalypha copperleaf, pivot, and weeding speed is slow.The active ingredient that the present invention introduced---the different monooctyl ester of methoxone then removes above-mentioned weeds performance efficiently to killing, it can be resolved into the acid of active ingredient methoxone rapidly in the weeds plant, quick-acting is remarkable, the drug effect mutual promoting action is obvious, grass family and broad leaved weed are all had preventive effect preferably, and a dispenser is the weeds in the controlled corn field whole growing.
Example preparation weeding test effect of the present invention sees the following form:
3, to the corn succession crop---wheat safety: according to China's crops farming characteristics and actual rotation of crops arrangement situation, the succession crop of corn is mainly based on wheat, and Herbicidal combinations involved in the present invention, its main component is nicosulfuron and the different monooctyl ester of methoxone, two kinds of compositions use the usage amount that can effectively reduce each one-component with, the different monooctyl ester of methoxone can be decomposed in the plant body rapidly simultaneously, metabolism is nontoxic material, has avoided to reaching the corn succession crop that usage amount caused---the nicosulfuron dominance of wheat or the possibility that stealthy poisoning takes place that same herbicidal effect need roll up nicosulfuron.
Example preparation of the present invention sees the following form to the safe effect of back stubble wheat:
4, formulation advanced person: but the preparation type of Herbicidal combinations involved in the present invention is the dispersed oil suspending agent, it is compared with traditional oil-suspending agent, wetting powder, and its advance has:
The more environmental protection of a, process, no dust drift;
B, using method are simpler, meet water and evenly disperse voluntarily, need not to stir;
C, soup spray more even, have increased pharmacodynamic stability, have reduced the possibility that poisoning takes place simultaneously.
