Abstract
The invention discloses a penoxsulam-clomazone pesticide composition. The penoxsulam-clomazone pesticide composition comprises a common auxiliary agent, penoxsulam and clomazone, wherein the mass ratio of the penoxsulam to the clomazone is 20:1-1:30, preferably 10:1-1:20. After the penoxsulam is compounded with the clomazone, the synergistic effect is obvious, the dosage of the pesticide composition is obviously less than that of single use of the component, and the penoxsulam-clomazone pesticide composition is applicable to controlling annual weeds in dry-land raised rice seedling field.
Description
Technical field
The composition pesticide that the present invention relates to is take penoxsuam with clomazone is active ingredient, is used for the control farmland weed, is particularly useful for preventing and kill off arid rice nursery annual weed etc.
Background technology
The chemical method weeding is one of upper Main Means of controlling weeds of agricultural.In recent years, because some weed killer herbicide kind large tracts of land are used separately, caused a lot of weeds to develop immunity to drugs.Simultaneously, grass when weeds occur is complicated mutually, not only annual and perennial weed is mixed gives birth to, draft, liana and shrub have concurrently, and weeds emerge uneven, seed, the staggered generation of low age, advanced age weeds, so when the weed killer herbicide kind is used separately, all can show in a certain respect defective and limitation.
Penoxsuam is rice field broad-spectrum herbicide after bud, can effectively prevent and kill off barnyard grass, moleplant seed and annual sedge weed, and effective to numerous broad leaved weeds, and the lasting period is long.It also can prevent and kill off anti-bensulfuron-methyl weeds in the rice field simultaneously, and many broad-leaveds and sedge weed and barnyard grass etc. are had residual activity, for composing the widest kind with herbicide in weed killer herbicide in present rice field.But penoxsuam is strong inhibitor of acetolactate synthetase, and medicament presents slower, needs the certain hour weeds just dead gradually.
Clomazone prevent and kill off object, annual gramineae and the broad leaved weeds such as barnyard grass, green foxtail, lady's-grass, setaria glauca, eleusine indica, black nightshade, elscholtiza, water sour jujube pin, kitchen garden, piemarker, flowerofanhour root or herb, lamb's-quarters, little lamb's-quarters, penny cress, willow leaf thorn knotweed, pale persicaria, dayflower, the rare Xian of hair, bur beggar-ticks, beggar-ticks, Siberian cocklebur, artemisiifolia.Perennial field thistle, setose thistle, corn sow thistle, meadow pine etc. there is stronger inhibitory action.
During the single use of penoxsuam and clomazone, certain defective and limitation are arranged all.
The inventor to penoxsuam He being mixed of clomazone conduct in-depth research, on the basis of a large amount of formula indoor screening tests and field medicine effect test, find penoxsuam with clomazone is mixed, in certain mixed ratio scope, paddy field weed is shown obvious synergistic effect, after further study, completed the present invention.
Penoxsuam is with being mixed and using of clomazone there is no report at present.
Summary of the invention
The object of the invention is to solve in prior art to farmland weed develop immunity to drugs problem and actual control efficiency relatively poor, provide a kind of efficient, low toxicity, quick-acting is good and the lasting period is long, is conducive to the composition pesticide of the farmland weed comprehensive regulation.
Another object of the present invention is to provide this composition pesticide is used for preventing and kill off farmland weed, is particularly useful for preventing and kill off arid rice nursery annual weed etc.
Technical scheme of the present invention: a kind of composition pesticide, take penoxsuam with clomazone is active ingredient, penoxsuam is with the ratio of quality and the number of copies of clomazone is 20:1～1:30, and preferably than being 10:1～1:20, all the other are to allow in agricultural chemicals to use and the acceptable auxiliary element.
Herbicidal combinations of the present invention is prepared into known method and is fit to upper any one formulation used of agricultural, reasonable formulation is a kind of in wetting powder, microemulsion, aqueous emulsion, suspending agent, oil-suspending agent or dosage form of water dispersible granule, and in preparation, the active ingredient total content is 1.0%～80%.
The auxiliary agent that uses in the present composition comprises that solvent, dispersant, stabilizing agent, emulsifier, antifreezing agent, thickener etc. and other are of value to the known substance of active ingredient stable and performance drug effect in preparation, all various compositions commonly used in pesticidal preparations or that permission is used, be not particularly limited, concrete composition and consumption require to determine by simple test according to formula.
Product described in the invention can finished product preparation form provide, namely in composition, each material mixes, the form that the composition of composition also can single dose provides, and directly mixes in tank or bucket before use, then is diluted to needed concentration.The frequency of administration of the present composition and amount of application change with weather condition and crop state variation, can reach the purpose of control by using suitable formulation.
The present composition is applicable to prevent and treat annual weed, especially the arid rice nursery annual weed.
Compared with prior art, beneficial effect of the present invention is, composite have an obvious synergistic effect, improved control efficiency; Enlarged the control spectrum; Two kinds of active ingredients are composite, reduced the agricultural chemicals usage amount, thereby reduced cost and the pollution that has reduced environment.
Embodiment
In order to make purpose of the present invention, technical scheme and advantage more short and sweet, the present invention describes with following specific embodiment, but the present invention only limits to absolutely not these examples.The following stated is only the present invention embodiment preferably, only is used for describing the present invention, can not be interpreted as the restriction to scope of the present invention.Should be pointed out that all any modifications of making within the spirit and principles in the present invention, be equal to replacement and improvement etc., within all should being included in protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
Embodiment one:Synergy type determination test to the paddy field annual weed.
Test material: chickweed [
Stellaria media(L.) Cyrillus] (field is collected seed and is preserved).Barnyard grass [
