The composition can be widely used for preventing and curing broad-leaf weed in gramineous crop fields such as wheat, rice, corn and the like, can improve the prevention effect and can enlarge the weeding spectrum, is safe to the crops and has high efficiency.
Description
Technical field
The present invention relates to a kind of composition pesticide, a kind of specifically Synergistic herbicide compositions that contains fluroxypyr.
Background technology
Fluroxypyr; Other titles: make it grand, chemical name: 4-amino-3.5-two chloro-6-fluoro-pyridine-2-fluoroacetic acid, the organic heterocyclic class selectivity inner sucting conduction type herbicide after seedling of The Dow Agrosciences, LLC. (Dow AgroSciences Company) Development and Production; Behind the medicine very soon by plant absorbing; Make sensitive plant the reaction of typical hormone herbicide occur, plant deformity, distortion, finally withered.Be applicable to that ground such as wheat, barley, corn, grape, orchard, pasture, forest land, lawn prevent and kill off broad leaved weed; Like clearvers, volume stem knotweed, kitchen garden, black nightshade, field bindweed, knotweed, amaranth etc., invalid to grassy weed.
Benzene oxycarboxylic acid and benzoic acid herbicide; One type of synthetic weed killer herbicide the earliest occurs, just found 2 as far back as the forties in 20th century, behind the powerful physiologically active that 4-drips; First systemic herbicide and sodium salt thereof have been succeeded in developing immediately; Succeeded in developing 2 successively again afterwards, a series of derivatives such as 4-d butyl ester, 2 first, 4 chlorine become one big type of weed killer herbicide.The effect characteristics of such weed killer herbicide: also can absorb through cauline leaf, conduct with transpiration current, also can be combined in the screen casing and conduct with photosynthate through xylem vessel through root system; Concentrate on growing point, be used to prevent and treat annual and perennial broadleaf weed, when being used for soil treatment; Weeds to annual gramineous weed and seminal propagation also have certain preventive effect, and such weed killer herbicide belongs to hormone herbicide, are faded in the position that is injured; Flavescence, withered, last complete stool is dead.
Phenyl ureagroup herbicides, have been reported the effect of 100 substitute urea compound tool inhibition plant growings at the mid-40.Nineteen fifty-one is found the herbicide effect of monuron, and many kinds of this type of weed killer herbicide occur in succession, particularly during the 60-70 age; Develop a series of halogenophenyl urea and fluorine-containing carbamide herbicides; Improved selectivity, enlarged and killed the grass spectrum, in agricultural production, be widely used.China is since the sixties in 20th century, and the grand kind of stepping on is pounced in No. one, chlortoluron, lorox, isoproturon, Sha successively to have produced weed killer herbicide.The core of the chemical constitution of phenyl ureagroup herbicides is ureas, and the substituting group in the urea molecule on the amino is different, and forms different phenyl ureagroup herbicides kinds; The carbamide herbicides of being called is also arranged; Main control annual weed, effective to broad leaved weed especially, the effect of control perennial weed is low.Main through suppressing the Hill reaction in the photosynthesis, light intensity helps the performance of drug effect.Through being absorbed by root system of plant, conduct to cauline leaf through transpiration current, accumulate in blade.Main controlling weeds seedling, effect is better before the weeds rudiment, makes soil treatment usually.
Summary of the invention
The objective of the invention is to work out a kind of and the prescription fluroxypyr compound synergic, enlarge the weeding scope of weed killer herbicide.
Below be the technical scheme that the present invention taked:
A kind of herbicidal composition that contains the fluroxypyr effective active; Said composition has following characteristic: inclusion compound A fluroxypyr; Compd B benzene oxycarboxylic acid and benzoic acid herbicide and phenyl ureagroup herbicides, the weight ratio of compd A and compd B are 1～30: 5～60.
Compd B benzene oxycarboxylic acid and benzoic acid herbicide principal item have: 2; 4-d butyl ester, 2 first, 4 chlorine sodium, 2 first, 4 chlorine isooctyls, 2 first, 4 chloromethane amine salt, 2 first, 4 chloroethene thioesters, 2 first, 4 chlorine, 2; 4 propionic acid, high by 2; 4-drips propionic acid, 2,4-Embutox, Vi par, mecopropP, Thistrol, 2 first, 4 chloramines salt, dicamba, match pine, TBA, chloramben or methoxy TBA;
Phenyl ureagroup herbicides principal item has: chlortoluron, isoproturon, lorox, diuron, Sha pounce on that grand, fluometuron, methylbenzene Sialon, cumyluron, isouron, buturon, bromax, methyldymron, phenobenzuron, metoxuron, afesin, Tupersan, fluorine sulphur are grand, neburea, isonoruron, tebuthiuron, in fluon, the dimefuron one or more.
In the composition of the present invention, the ratio of compound (A) and compound (B) mixture can be according to the kind of said composition, spraying time, application process and in a more wide in range scope, is fluctuateed.Generally speaking, compd A and compd B are listed as this component proportioning by following component and weight proportion but be not limited to.
Compd A 1～30%
Compd B 5～60%
Said herbicidal composition adds various auxiliary materials, auxiliary agent according to the method for routine, is processed into following formulation: microemulsion, wetting powder, suspending agent, granule, aqueous emulsion, soluble powder or this area known all passable formulations.
If with the wetting powder is example, can in composition components, adds dispersant, wetting agent, filler and implement.Wherein said dispersant is a kind of or any several kinds of combinations in the dispersant commonly used of NNO, MF, SOPA270, lignosulfonates, polyethers and this area; Described wetting agent is K12, NPE, AEO series, ooze a kind of or any several kinds of combinations in the wetting agent commonly used of T, alkyl phenol (or fatty alcohol) polyoxyethylene poly-oxygen propylene aether and sulphate (or phosphoric acid fat) thereof and this area.Said filler: a kind of or any several kinds of combinations in diatomite, white carbon, bentonite, precipitated calcium carbonate, the attapulgite.Collocation method does; Fluroxypyr, another active component, dispersant, wetting agent, residue filler are dropped in the mixing kettle and stir, then the material of mixing is crossed airslide disintegrating mill, and then stir through mixing kettle; Fineness is crossed 325 mesh sieves; After treating that the detection of each item index is qualified, carry out packing, getting semi-finished product is Herbicidal combinations wetting powder of the present invention.
Usefulness of the present invention and good effect:
(1) grass that kills that has enlarged fluroxypyr and SA composition is composed; Fluroxypyr belongs to picolinic acid class weed killer herbicide; The selectivity seedling post-treatment agent of habit in belonging to can be prevented and kill off multiple broad leaved weed, and responsive have weeds such as clearvers, hollow lotus seeds dish; Mostly carbamide herbicides is processing soil treatment agent, compositely can play the effect of closing down economic benefits and social benefits.(2) a large amount of evidences, both synergy that have been mixed enlarge the effect of killing the grass spectrum.
Said composition can be widely used in the wheat class, paddy rice, and control broad leaved weed in gramineous crop fields such as corn can improve preventive effect, and enlarge and kill the grass spectrum, and to crop safety, efficient.
