Abstract
A composite herbicide for monocotylous and bicotylous weeds contains monosulfometuron and one or tow herbicide other than sulfonylurea class. Its advantages are high effect, broad sepctrum and high safety.
Description
What the present invention relates to found based on a total technology and inventive concept has a Herbicidal combinations that improves performance, particularly relates to the binary or the ternary weeding composition that are composited with weeding active ingredient monosulfmeturon (A) and one or two active ingredient B that is selected from the herbicidal active component except that sulfonylurea.
Monosulfmeturon is a kind of sulfonylurea new herbicides, it is inner sucting conduction type weed killer herbicide before the bud of succeeding in developing by Nankai University, behind the bud, by suppressing the activity of acetolactate synthestase (ALS), branched-chain amino acid becomes interrupted entirely in the plant corpus and make, thereby destroy cell division and growth, cause the weed growth function to be obstructed, make the weeds necrosis.The activity of weeding of this weed killer herbicide is high, and the weeds spectrum is wide, can prevent and kill off most broad leaved weeds effectively, as Monochoria vaginalis, pondweed, mexicana etc., and sedge weed such as difformed galingale herb etc.Both can make soil treatment, and can make cauline leaf again and handle, selectivity is strong, to plant height safety.But its preventive effect to grassy weed common in the farmland such as barnyard grass grass is unsatisfactory.In addition, the registration of the green precious agrochemicals scientific and technological development in the existing Tianjin of its single agent formulation Co., Ltd is produced, both at home and abroad the composition of also not mentioned it and other weeding active ingredient of patent.Therefore its effect of mixing use with other weeding active ingredient is unforeseen.
Through test of many times, have now found that, the stack that binary that monosulfmeturon (A) and weeding active ingredient B of the present invention are composited or the herbicide action that ternary weeding composition showed or activity level have all exceeded each composition activity, this exercising result is called synergistic effect.The present invention is based on this result, one group of Herbicidal combinations is provided.
Content of the present invention is to be equipped with weeding active ingredient B with monosulfmeturon (A), and all the other are acceptable carrier on the agrochemistry, and wherein active ingredient weight ratio A: B is 0.1～50: 0.1～99.9, and total active ingredient can account for 0.1～99.9% of composition.
Weeding active ingredient B of the present invention, can be one or both in all the other all kinds of weeding active ingredients except that sulfonylurea, for example Acetochlor (acetochlor) of amide-type (Amides), isopropyl methoxalamine (metolachlor), propisochlor (propisochlor), mefenacet (mefenacet), butachlor (butachlor), alachlor (alachlor), propachlor (propachlor) etc.; The atrazine (atrazine) of triazine (Triazines), cyanazine (cyanazine), prometryn (prometryn), Simanex (simazine) etc.; The piperazine humulone (metribuzin) of three pyridine ketones (Trazinones) etc.; The cycloxydim (cycloxydim) of cyclohexene two ketones (cyclohexanediones) etc.; The dichloro quinolinic acid of picolinic acid class (quinclorac) (quinclorac), fluroxypyr (make it grand) (fluroxypyr) etc.; 2 of phenoxy carboxylic acid, 4-drip (2,4-D), 2 first, 4 chlorine (MCPA) etc.; Oxadiazole class (oxadiazoles) De Evil humulone (Evil grass spirit) (oxadiazon), Bing Que Evil humulone (oxadiargyl) etc.; And Chinese mugwort cuts (Cinmethylin) and waits other all kinds of weeding active ingredients, and they with monosulfmeturon kill the grass spectrum complementary or mix after the remarkable synergistic effect of tool.
The carrier that each formulation of the weed killer herbicide that carrier of the present invention is well known to those skilled in the art is required, for example filler, surfactant, adhesive, emulsifier and solvent etc.Their object lesson such as white carbon, diatomite, clay, high towering like a mountain peak soil, talcum, calcium carbonate, draw back powder, NNO, sodium alkyl benzene sulfonate, polyvinyl alcohol, starch, OP emulsifier, water etc.
The formulation of Herbicidal combinations of the present invention is wetting powder and suspending agent preferably, also can be other formulations such as missible oil, pulvis and granule.
Mixture, inert carrier and the filler and one or more wetting agents and the dispersant that contain each active component in this Herbicidal combinations wetting powder.Carrier is generally mineral inert substance such as potter's clay, kaolin, bentonite, talcum powder, diatomite etc.The wetting powder of the Herbicidal combinations of this invention contains the active component mixture of 0.5～90% (weight) (more excellent is 4～80%) usually, the dispersant of～25% 0.5 (more excellent is 1～15%) (weight), the inert solid carrier and the filler of 5～96% (weight) (more excellent is 5～80%).Form herbicidal composition jointly by them.
The suspending agent of this Herbicidal combinations is that each water-soluble relatively poor active component is constantly stirred in water with emulsifier, dispersant, wetting agent etc., makes it evenly to disperse and suspend, so that spraying is used.Can suitably add thickener, antifreezing agent, defoamer etc. as required.Suitable suspending agent comprises the active component of 0.1～90% (weight) (more excellent is 0.5～60%).Above-mentionedly decide by the solubility limit of active component in solvent.
This Herbicidal combinations missible oil is that each active ingredient with Herbicidal combinations is dissolved in as in a certain solvent in butanols, cyclohexanone, dimethyl formamide, dimethylbenzene or high boiling aromatic series or the hydro carbons, adds one or more emulsifier again and is prepared from.Active constituent content is approximately 0.1～90% (weight) (more excellent is 5～80%) in the missible oil.
This Herbicidal combinations pulvis be with each active ingredient and fine grain be dispergated solid matter as sliding clay and kaolin, bentonite, pyrophyllite or diatomite through abrasive dust processing and make.Pulvis contains about 0.1～50% (weight) of effective composition (more excellent is 2～40%).
The preparation of this Herbicidal combinations granule is that each active ingredient is sprayed at particulate inert material surface with absorption property or active ingredient is adhered to carrier mass surface or particulate inert material surfaces such as sand, kaolin with adhesives such as polyvinyl alcohol, Sodium Polyacrylate or mineral oil, also can the active ingredient that some is suitable be processed into granule with the method for common manufacturing granular fertilizer.Its active constituent content of dispersible granules agent (weight) between 5～90% in the water spreads fertilizer over the fields active constituent content (weight) between 1～50% in the granule, more preferably is between 1～25%.
Herbicidal combinations provided by the invention has the activity of weeding height, and the characteristics of broad weed-killing spectrum are single with once can effectively preventing and kill off the sub-weeds of the perennial single double leaf of the common annual and part in farmland.They are to broad leaved weed such as acalypha copperleaf, kitchen garden, lamb's-quarters, piemarker, black nightshade, Siberian cocklebur, Monochoria vaginalis, pondweed etc., sedge weed such as difformed galingale herb, pure Mi Shacao, Herba Cyperi Glomerati, convexutricle sedge herb etc., grassy weed such as barnyard grass grass, wolf tail grass, moleplant seed, wild swallow grass etc. have significant preventive effect.
The invention has the advantages that: monosulfmeturon is to go through the sulfonylurea inner sucting conduction type weed killer herbicide of succeeding in developing in 10 years by Nankai University, by suppressing the activity of acetolactate synthestase, make the branched-chain amino acid biosynthesis block, and cell division and growth are destroyed.It is combined into binary or ternary weeding composition with different action principles, different site of action, different weeding active compound B or the combination agent B that kills the grass spectrum; like this; it is with strong complementarity to kill grass; kill careless spectrum width; the preventive effect of single broadleaf weed common in the farmland is significantly higher than the preventive effect of monosulfmeturon; and reduce the application dosage of every kind of active substance significantly; this characteristic has important ecological significance; can delay the succession of drug-fast generation of weeds and weed community, also significant to the protection environment.
