Abstract
Herbicidal agents containing A) glufosinates or their salts or similar agents like bialophos, B) a nitrodiphenyl ether herbicide like oxyfluorophene and C) an alkyl polyglycol ether sulphate tenside have synergistic herbicidal effects. Components A, B and C can be jointly formulated in the form of an aqueous emulsion in which there are 1-15 % A), 0.1 to 5 % B), 1-15 % C), 3 to 30 % organic solvent, 40-60 % water, 2-10 % emulsifier and 0 to 20 % ordinary formulation auxiliaries.
Description
The invention belongs to and to be used for preventing and treating the crop protection agents field of green bristlegrass grass, particularly herbicidal composition field.
Grass ammonium phosphine (1)
That is, 4-[hydroxyl (methyl) phosphono]-ammonium salt of DL-high lactamine, be known weed killer herbicide, it absorbs (blade face effect weed killer herbicide) through the green portion of plant; Referring to " agricultural chemicals handbook the 9th edition, the Britain plant protection committee, 1991, the 458 pages.Grass ammonium phosphine mainly is in raise crop and farming ground, by specific application technique, is used for preventing and treating broad leaved weed and grassy weed behind the bud, also can be used in the ranks handling in agriculture row crop such as corn, cotton etc.Formula (1) compound contains asymmetric carbon atom.The L-enantiomer is considered to the biologically active isomer.
Disclose in addition, the effect of careless ammonium phosphine and its L-enantiomer can improve significantly with surfactant, preferably uses the wetting agent that belongs to alkyl polyglycol ether sulfate series, for example, with its alkali metal salts or ammonium salt form, still, can be its magnesium salts also, as C
12/ C
14-aliphatic alcohol diethylene glycol ether sodium sulfate salt (gram enapol LRO, Hoechst); Referring to EP-A-0476555, EP-A-0048436, EP-A-0336151 or US-A-4,400,196 and concentrate " influence herbicidal activity and the optionally factor " literary composition deliver, 227-232 (1988) in the EWRS nd Annual Meeting.Also disclose alkyl polyglycol ether sulfate in addition and also be suitable for, be used for a series of other weed killer herbicides, especially for the diphenyl ether weed killer herbicide as bleeding agent and synergist; Referring to EP-A-0476555.
Surprising is, have now found that, grass ammonium phosphine or relevant active substance can be advantageously with some nitro diphenyl ether weed killer herbicide with as the anion surfactant combination that belongs to alkyl polyglycol ether sulfate series of bleeding agent, produce Synergistic active.
The present invention relates to weed killer herbicide, it comprises the following composition of effective dose, and composition comprises following composition: A) one or more formulas (A) compound or its salt
Wherein
Z be following group :-OM ,-NHCH (CH
3) CONHCH (CH
3) COOM or
-NHCH (CH
3) CONHCH[CH
2CH (CH
3)
2] COOM, wherein under each situation, M be hydrogen or
Inorganic or organic cation, B) one or more nitro diphenylether herbicidal compounds, and C) a kind of anion surfactant that belongs to alkyl polyglycol ether sulfate series.
Formula (A) comprises all stereoisomers and composition thereof, particularly its racemic modification and each bioactive enantiomer.
The embodiment of the active substance of formula (A) has following: the careless ammonium phosphine (acid) of the racemic form of a1) having mentioned already (glufosinate) and ammonium salt; a2) the L-enantiomer of careless ammonium phosphine (acid) and ammonium salt thereof; a3) bilanafos; that is L-2-amino-4-[hydroxyl (methyl) phosphono ,] bytyry-L-alanyl-L-alanine and sodium salt thereof.
The conventional amount of application of grass ammonium phosphine racemic modification itself is between 200 to 1000 gram gram active component/hectares.Under such dosage, when careless ammonium phosphine is that it is effective especially when the green portion of plant absorbs.Because it was degraded by microorganisms in several days in soil, thereby did not have long-acting in soil.This point is suitable for active substance bilanafos-sodium equally; Referring to " agricultural chemicals handbook, the 9th edition, 1991, the 75 pages in the Britain plant protection committee.

US-A-5,324,708 disclose the preparation of the preparation that contains weed killer herbicide grass ammonium phosphine, particularly its non-hygroscopic salt form and Oxyfluorfen combination.The combination of these weed killer herbicides and anionic wetting agent is not described in this document.US-A-5, the information of the Synergistic active aspect of the biological Examples of 324,708 these combinations of herbicides of shortage and careless ammonium phosphine and Oxyfluorfen combination.
The combination of careless ammonium phosphine and other weed killer herbicide is disclosed in the Research Bulletin (Research Disclosure) 275 (1987), 154, to widen careless ammonium phosphine action spectrum.In particular, this document is mentioned the combination of careless ammonium phosphine and Oxyfluorfen and is used for cotton.This document lack the combination of careless ammonium phosphine and Oxyfluorfen or with the information of the Synergistic active aspect of aliphatic alcohol polyethylene glycol sulphate combination.
Surprising is, have found that, when A type weed killer herbicide in the presence of surfactant C, with-kind or the multiple active substance combination that belongs in the B group when using, observed super adduction (=synergy) effect.Compare with adopt single weed killer herbicide separately in the presence of wetting agent C, the activity of combination is significantly high.These effects make that consumption reduces, wideer broad leaved weed and grassy weed control spectrum, more promptly bring into play herbicide effect, longer action time, by applied once or minority using several times, noxious plant is is better prevented and treated and widened becomes possibility possible service time.These performances are required in the actual use of control of weeds, make crops not have harmful competitive plant, and therefore guarantee and/or increase output from the angle of matter or amount.This novel composition obviously surpasses prior art on above-mentioned performance.
The best of weight ratio and consumption for example may be selected to depend on the vegetative period, weeds spectrum and the environment that mix pairing component, broad leaved weed or grassy weed-and climatic factor.
So A of the composite weedicide of A type and Type B: the weight ratio of B can change in wide scope, and generally speaking, is between 100: 1 and 1: 5, preferably between 10: 1 to 1: 1.Following weight ratio A: B is preferred for the particularly careless ammonium phosphine of A type weed killer herbicide (racemic mixture) :-with Oxyfluorfen be 10: 1 to 2: 1, particularly 8: 1 to 3: 1.-with lactofen be 10: 1 to 2: 1, particularly 8: 1 to 3: 1.-with bifenox be 10: 1 to 2: 1, particularly 8: 1 to 3: 1.-with fluoroglycofen-ethyl be 100: 1 to 10: 1, particularly 50: 1 to 10: 1.-with acifluorfen be 10: 1 to 2: 1, particularly 8: 1 to 3: 1.-with Fomesafen be 10: 1 to 2: 1, particularly 8: 1 to 3: 1.
When using with the form of combination, the amount of application of the weed killer herbicide of herbicide application amount during than single using is much lower, but identical effect is provided.Generally speaking, A type weed killer herbicide, preferred careless ammonium phosphine, amount of application are 100 to 600 gram active component/hectares, the nitro diphenyl ether, and as preferred Oxyfluorfen and lactofen, amount of application is 50 to 150 gram active component/hectares.
The optimum spraying amount of C type anion surfactant depends on weed killer herbicide and already mentioned factor, and generally speaking, in surface reactive material (SAS), be between per hectare 100 and 2000 gram surfactants, preferred 500 to 1500 gram surface reactive material/hectares.Therefore, the weight ratio of weed killer herbicide A and surfactant C preferably 1: 1 to 1: 10, particularly 1: 2 to 1: 5.
The present composition acts on the weeds of wide spectrum.For example, they are suitable for preventing and treating annual and perennial weed, as Agropyron, Paspalum, cogon, Pennisetum, japanese bearbind genus, Cirsium, Rumex and other.
The present composition can be used for optionally preventing and treating annual and perennial noxious plant in raise crop and fruit tree and the viticulture, raise crop such as oil palm, coconut palm palm fibre, rubberplant, citrus, pineapple, cotton, coffee, cocoa or the like.Equally, composition of the present invention can be used for using the thing ploughed of non-farming or no-tillage method to produce.In addition, they can be used in road, open ground and industrial land etc. in non-selective mode, keep the no green bristlegrass grass growth of these areas.
The salient point of the present composition is the herbicide effect that it is rapid and long-acting.The resistance of rainwater washing against of active substance is good in the present composition.Special advantage is, be used for the formula (A) of composition and (B) effective dose of compound be so low, their soil effect reduces greatly.This is to make it be applied to sensitive crop for the first time to become possibility, and in addition, phreatic pollution is actual to be avoided.Composition by active substance of the present invention and wetting agent reduces required active substance amount of application greatly.
Therefore the method that the present invention also relates to prevent and treat the green bristlegrass grass, this method comprises, and one or more A type weed killer herbicides are applied to part or the cultivation area of noxious plant, these plants with one or more Type B weed killer herbicides and a kind of C type anion surfactant.
