Description
Technical field
The present invention relates to field of pesticide preparation, particularly a kind of Herbicidal combinations and preparation thereof.
Background technology
Corn is one of staple food crop of northern China, maize sown area reaches about 300,000,000 mu, be distributed in about 24 provinces, municipalities and autonomous regions, mainly comprise main province, the districts such as Heilungkiang, Jilin, Liaoning, Hebei, Shandong, Shanxi, Henan, Shaanxi, Sichuan, Guizhou, Yunnan, Guangxi.The annual production of corn reaches more than hundred million tons, accounts for 20% of Gross World Product.But the weeds of wheat paddock occur general, and of a great variety, crop smothering can cause the serious underproduction.Therefore, in wheat paddock, the use of weed killer herbicide is very general.
Flumicloracpentryl, its chemical name is [the chloro-5-of 2-(hexamethylene-1-alkene-1,2-dicarboximide base)-4-fluorophenoxy] acetyl pentyl ester, belong to phthalmide, a kind of broad spectrum activity contact killing type herbicide after seedling, for except killing the annual and perennial broadleaf weeds such as black nightshade, lamb's-quarters, ox chickweed, Amaranthus weeds, Euphorbia maculata.It has interior suction, conduction, and medicament, by after susceptible weeds Foliage Absorption, acts on plant tissue rapidly, causes protoporphyrin to accumulate, and Cell membrane lipids peroxidation is strengthened, thus causes cell structure and the cell function irreversible lesion of susceptible weeds.The metabolic breakdown that carries out that can be very fast after gramineous plants absorption makes it to lose efficacy, therefore the pesticide resistance that performance is stronger.Safer to gramineous crops such as wheat, corn, millet, paddy rice, flumicloracpentryl disappears in soil after microorganism is comparatively fast decomposed, and namely there will be lopsided curling symptom with latter general 24 hours broad leaved weeds, and 15-20 days dead.
Methoxyphenone, chemistry (±) 2-(1-(ethoxy imino by name) butyl) own-2-ketenes of-3-hydroxyl-5-thiophene alkane-3-basic ring, belong to novel broad-leaved field high activity alkyl thiazolinyl type herbicides, its mechanism of action is mitotic inhibitor, after being absorbed by weeds root and leaf, conduct in plant, weeds are stopped growing, then withered.Methoxyphenone broad weed-killing spectrum, can be used for preventing and kill off annual and perennial grassy weed, as wild oat, mouse tail amur foxtail, perennial ryegrass, spontaneous Cereal, large bent grass, can be used for wheat paddock control annual gramineous weed.
Weeds of wheat mixes growth with grass family and broad leaved weed, and alone methoxyphenone is excellent to the preventive effect of grassy weed, but invalid to broad leaved weed.And agricultural chemicals single dose be used alone for a long time easily make weeds produce resistance.
Summary of the invention
In view of this, the invention provides a kind of Herbicidal combinations and preparation thereof.This Herbicidal combinations and preparation synergistic effect remarkable, expand herbicide spectrum, greatly reduce dosage and times for spraying, there is the advantages such as use age wide, safe, efficient, lasting period length, environmental protection, and delay the generation of herbicide resistance, effectively can prevent and kill off most of weeds of wheat paddock, broad leaved weed and grassy weed preventive effect are strengthened.
In order to realize foregoing invention object, the invention provides following technical scheme:
The invention provides a kind of Herbicidal combinations, be made up of flumicloracpentryl and methoxyphenone.
Flumicloracpentryl, its chemical name is [the chloro-5-of 2-(hexamethylene-1-alkene-1,2-dicarboximide base)-4-fluorophenoxy] acetyl pentyl ester, belong to phthalmide, a kind of broad spectrum activity contact killing type herbicide after seedling, for except killing the annual and perennial broadleaf weeds such as black nightshade, lamb's-quarters, ox chickweed, Amaranthus weeds, Euphorbia maculata.It has interior suction, conduction, and medicament, by after susceptible weeds Foliage Absorption, acts on plant tissue rapidly, causes protoporphyrin to accumulate, and Cell membrane lipids peroxidation is strengthened, thus causes cell structure and the cell function irreversible lesion of susceptible weeds.The metabolic breakdown that carries out that can be very fast after gramineous plants absorption makes it to lose efficacy, therefore the pesticide resistance that performance is stronger.Safer to gramineous crops such as wheat, corn, millet, paddy rice, flumicloracpentryl disappears in soil after microorganism is comparatively fast decomposed, and namely there will be lopsided curling symptom with latter general 24 hours broad leaved weeds, and 15-20 days dead.
Methoxyphenone, chemistry (±) 2-(1-(ethoxy imino by name) butyl) own-2-ketenes of-3-hydroxyl-5-thiophene alkane-3-basic ring, belong to novel broad-leaved field high activity alkyl thiazolinyl type herbicides, its mechanism of action is mitotic inhibitor, after being absorbed by weeds root and leaf, conduct in plant, weeds are stopped growing, then withered.Methoxyphenone broad weed-killing spectrum, can be used for preventing and kill off annual and perennial grassy weed, as wild oat, mouse tail amur foxtail, perennial ryegrass, spontaneous Cereal, large bent grass, can be used for wheat paddock control annual gramineous weed.
In different Herbicidal combinations, each active component is due to the difference of composition, structure, physicochemical property, makes the synergy between each active component be typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and its effect produced is greater than the sum total of each composition effect; And summation action is exactly the sum total that its effect produced equals each composition effect; When antagonism refers to that two kinds of materials act on living organism, a kind of material disturbs the effect of another kind of material, or the effect of interfering with an opponent each other, makes the phenomenon that general effect declines.
The present invention evaluates two kinds of mixed interactions of different activities component in Herbicidal combinations of the present invention with reference to Sun Yunpei (Sun Y-P) method.The present invention by calculate flumicloracpentryl mixed with methoxyphenone after co-toxicity coefficient, effect after both evaluations are mixed, result shows, and the weight ratio of flumicloracpentryl and methoxyphenone is 1:(4 ~ 12) co-toxicity coefficient be all greater than 120.Found by outdoor biological activity determination test (field control effectiveness test), the weight ratio of flumicloracpentryl and methoxyphenone is 1:(4 ~ 6) ratio used in combination there is notable synergistic effect.As can be seen here, the flumicloracpentryl in the present invention and methoxyphenone combine in certain proportion, and both are composite, and synergistic effect is obvious, decreases active ingredient dosage, adds safety, delayed the generation of herbicide resistance, can be widely used in agriculture field.
As preferably, the weight ratio of flumicloracpentryl and methoxyphenone is 1:(4 ~ 12).
Preferably, the weight ratio of flumicloracpentryl and methoxyphenone is 1:(4 ~ 7).
More preferably, the weight ratio of flumicloracpentryl and methoxyphenone is 1:(4 ~ 6).
Present invention also offers this Herbicidal combinations and prepare the application in eliminating weed in wheat field Herbicidal combinations preparation.
Present invention also offers a kind of Herbicidal combinations preparation, be made up of auxiliary material acceptable in this Herbicidal combinations and Pesticide Science.
As preferably, in the present invention, the formulation of Herbicidal combinations preparation is wetting powder or water dispersible granules.
As preferably, the percentage by weight that Herbicidal combinations accounts for Herbicidal combinations preparation is 1% ~ 90%.
In embodiments more provided by the invention, the percentage by weight that Herbicidal combinations accounts for Herbicidal combinations preparation is 30% ~ 80%.
