Remove B5 (AC014), outside B4 (TH-913) and the B12 (IC940), the category-B compound is at " The pesticide Manual " (" agricultural chemicals handbook "), the 9th edition, Brit, Crop.Prot.Council all are known in 1991, and B5 is on the books in number of patent application US5009699, B4 (TH-913) is documented among the EP0238070, and B12 (IC940) is documented among the Japanese patent application J-60087254.
Enumerate the example of some desired combination of active principles agent below, but be not limited to this:
Anilofos+bensulfuron-methyl
Anilofos+bensulfuron-methyl+sand-grass is grand
Anilofos+pyrazosulfuron
Anilofos+pyrazosulfuron+sand-grass is grand
Anilofos+pyrazosulfuron
Anilofos+pyrazosulfuron+sand-grass is grand
Anilofos+TH913
Anilofos+TH913+ sand-grass is grand
Anilofos+AC014
Anilofos+AC014+ sand-grass is grand
In these listed combination agent, use sand-grass to swell two obvious superiority are arranged, the grand herbicidal effect that has strengthened Cyperus weeds and grassy weed of first sand-grass, sand-grass is grand has on the other hand played the effect of safener to rice plant, has reduced for example sulfonylurea derivative potential poisoning that may cause of weed killer herbicide.The safety effectiveness of the combination agent of JC-940 and anilofos also is proved.
Observe with similar method, in the combination agent of anilofos and pyrazosulfuron, anilofos has been given play to wonderful safety effect.The poisoning to paddy rice of using separately pyrazosulfuron or may causing during with other herbicide mixture can be by using anilofos alleviate or eliminating fully.So these combination of active principles agent have shown some novel characteristics, these characteristics have surmounted known so far effect, are fully unexpected and astonishing.
Weeding composition of the present invention has good broad-spectrum weed-killing effect to unifacial leaf or the dicotyledonous harmful plants that those have important economic implications.So with combination agent of the present invention also can prevent and kill off perennial weeds that those are difficult to prevent and treat effectively with stem tuber, rhizome or other perennating organ breeding, to prior to seeding, before the bud or use unimportant behind the bud.
Here enumerate the unifacial leaf that some available present compositions prevent and kill off and the representative example of broadleaf weed, but be not limited to cited kind.
The monocotyledon weed that can prevent and kill off effectively is that for example barnyard grass is careless and annual cyperus and perennial cyperus.
Combination of active principles agent of the present invention can prevent and kill off very effectively the weeds that under the paddy field cultivation condition, occur as,
Figure C9311960900141
Mushroom, rhizoma alismatis, Monochoria vaginalis, water chestnut, firefly Lin, nutgrass flatsedge etc.
Herbicidal combinations of the present invention is applied to soil surface before emerging, it or stop weeds to emerge fully, or when the weeds seedling grows to leaf period, stop growing, continue in 3 to 4 week back death fully.
, stop growing very soon after administration is handled as if the green portion that the combination agent of active ingredient is applied to plant in the back of emerging.The plant of weeds rests on growth and development stage that medication handles or through the back is dead rapidly after a while, those is removed as early as possible or for good and all for the new compositions that crops have the weeds the application of the invention that is harmful to the effect of striving unexpectedly.
Though composition of the present invention has excellent herbicidal for unifacial leaf one and broadleaf weed, it is very little or be safe from harm fully to the harm of paddy rice.For these reasons, so the present composition is particularly suitable for being used for optionally preventing and kill off the growth that does not need plant in paddy field.
Its herbicidal effect of combination of active principles agent of the present invention has surpassed the wherein desired herbicidal effect sum of each single agent, and the raising of this herbicide effect effect can make the consumption of each active ingredient significantly reduce.The composition of each weed killer herbicide hold that the phase of putting also can be improved or its speed of action is accelerated.These characteristics provide very significant superiority when the actual management of weeds for the user.It can make the control of weeds more cheap, faster, and saving of labor and hold effect more also can increase the output of crops thus.
Find further that also this combination of active principles agent series also has safety effect or detoxication, promptly used active ingredient reduces or elimination fully the plant toxicity side effect of crops such as paddy rice.
The mixed proportion of different active ingredient components can in very large range change.It is particularly relevant with these factors of weather conditions with used pairing component, weed growth developmental stage, weeds spectrum.
Combination of active principles agent of the present invention can provide with the mix preparation form of two components, this mix preparation can dilute with water or can be made into the granule form and use with usual manner, perhaps also the preparation of each single effective ingredient can be diluted so-called barrel of mixed thing jointly by water.
Compound (combination agent) can be processed into different formulations by the biology of being given and/or chemistry-physical parameter.The formulation that can process is: wetting powder (WP), missible oil (EC), the aqueous solution (SL), emulsion (EW) are as O/w emulsion and water-in-oil emulsion, solution that can spray or emulsion, with oil or water is the dispersion liquid of matrix, suspension emulsion, pulvis (DP), impregnating agent, dispersible granules agent (WG) in granule of particularly using in the soil or spreading fertilizer over the fields or the water, ultralow amount formulation, microcapsule formulations or cerate.
These formulations are known basically, the record in following document

On the basis of these formulations, these combination agent can with other pesticide active ingredient material such as other weed killer herbicide, bactericide or insecticide, and fertilizer and/or plant growth regulator be mixed, for example it can be processed into a kind of form or mixed thing form of bucket of finished product preparation.
Can homodisperse wetting powder in water except the active ingredient and a kind of thinner or inert substance that contain agricultural chemicals; also contain wetting agent; as the ethylating induced by alkyl hydroxybenzene of polyoxy; the ethylating fatty amine of ethylating aliphatic alcohols of polyoxy or polyoxy, alkane-or benzene sulfonamide acid esters class and dispersant, as sodium lignin sulfonate; 2; 2 '-dinaphthyl methane-6,6 '-sodium disulfonate, dibutyl naphthalene-sodium sulfonate or oleoyl N-methyltaurine sodium.
Missible oil is that the active ingredient with agricultural chemicals is dissolved in as butanols, cyclohexanone, and dimethyl formamide in a certain solvent in dimethylbenzene or high boiling aromatic series or the hydro carbons, adds one or more emulsifier again and is prepared from.Compound as emulsifier for example can adopt alkyl aryl sulphonic acid calcium salt such as calcium dodecyl benzene sulfonate, or nonionic emulsifier such as fatty acid polyethylene glycol ester, alkylaryl polyglycol ether, fatty alcohol polyglycol ether, expoxy propane one oxirane condensation product, alkyl, polyether, fatty acid esters of sorbitan, polyoxyethylene deoxysorbitol fatty acid ester or polyoxyethylene sorbitan ester.
Pulvis be with active ingredient and fine grain, be dispergated solid matter such as talcum, natural clay and kaolin, bentonite, pyrophyllite soil or diatomite are through abrasive dust processing and make.
The preparation of granule is active ingredient to be sprayed at the particulate inert material surface with absorption property or with the active ingredient polyvinyl alcohol, these adhesives of Sodium Polyacrylate or mineral oil adhere to carrier mass surface or particulate inert material surfaces such as sand, kaolin.Also can the active ingredient that some is suitable be processed into granule with the method for common manufacturing granular fertilizer.When needing also can with the fertilizer processing that mixes.
Agrochemical formulations contains effective constituents A or the B of 0.1-99% (weight), particularly 2-95% (weight) usually.The concentration of effective constituents A and B is different in various formulations.
The concentration that contains effective composition in the wetting powder is greatly about 10-90% (weight), and remainder is made up of some formulation auxiliary materials commonly used.Active constituent content is approximately 1-85% (weight) in the missible oil, preferably contains effective composition 5-80% (weight).Pulvis contains effective composition and is approximately 1-25% (weight), and major part is 5-20% (weight).The solution that can spray contains effective composition and is approximately 0.2-25% (weight), preferred 2-20% (weight).Granule is for example in the water in the dispersible granules agent, and active constituent content depends on that partly active ingredient is to be in a liquid state or solid-state and use which type of particle auxiliary agent and filler.Usually in water in the dispersible granules agent, its active constituent content is between 5-90% (weight).Spread fertilizer over the fields active constituent content (weight) between 1-50% in the granule, between the preferred 2-25%.
In addition, also contain conventional adhesive, wetting agent, dispersant, emulsifier, bleeding agent, solvent, filler or carrier in the cited active ingredient formulation sometimes.
Usually the formulation that provides with commercial form needs to adopt the conventional method dilution in use sometimes, wetting powder for example, missible oil, dispersible granules agent dilutable water in dispersant and the water.And pulvis spreads fertilizer over the fields or the granule used in soil and the solution that can spray need not further to dilute with inert substance before using.
The consumption of combination agent changes because of the difference of external condition such as temperature, humidity, used weed killer herbicide kind.

Biological Examples
1. herbicidal effect before the bud
With the plastic basin that fills dauk that the seed or the stem tuber of unifacial leaf and broadleaf weed places diameter 9cm, topped with soil above.The seed of weeds in paddy field is cultivated in water saturated soil, adds water to the depth of water and cross soil surface or exceed soil surface number centimeter in cultivation in basin.Become suspension or emulsion with the wetting powder of combination of active principles agent of the present invention or missible oil and as the corresponding dosage forms thin up that contains single active ingredient of parallel test, the dilution amount of water is equivalent to about 300 to 600 liters/hectare, by various dose potted plant topsoil is sprayed then and handles or under the situation of rice plant is arranged medicament is joined in the irrigation water.
After handling basin is placed among the greenhouse, keep the condition that helps weed growth.3 to 4 Zhou Houyu not dispenser control group compare, the plant victimization state after germinateing or germinate with visually rank method evaluation test plant.Result of the test has confirmed that weed killer herbicide of the present invention has herbicidal effect before the good wide spectrum bud for broad-leaved and grassy weed.
In all cases, the calculated value of combination agent herbicidal effect is different with measured value.Calculated value is promptly according to S.R.Colby formula (" synergy of weeding composition and antagonism are calculated ", the theoretical expected value of the resulting combination agent herbicidal effect of Weed 15 (19677, the 20-22 page or leaf).
The computing formula of binary combination agent is: E = X + Y - X &CenterDot; Y 100 The computing formula of ternary weeding active ingredient is: E = X + Y + Z + X &CenterDot; Y &CenterDot; Z 10000 ( X &CenterDot; Y + X &CenterDot; Z + Y &CenterDot; Z ) 100 In the formula
X=when weed killer herbicide A consumption is xkg/ha by the drug effect % due to the A;
Y=when weed killer herbicide B consumption is ykg/ha by the drug effect % due to the B;
When another weed killer herbicide of Z=C consumption is zkg/ha by the drug effect % due to the C;
E=weed killer herbicide A+B (or A+B+C) when its consumption is x+y (or x+y+Z) kg/ha, expect by the medicine due to them.
If actual drug effect value is greater than the calculated value of expection, then combination agent has the addition effect of action effect greater than its each single agent, also promptly has synergistic effect.
Its herbicidal effect of combination of active principles agent of the present invention is higher than wherein each single component and uses desired effect (according to the calculated value of Colby formula) separately.So the combination of active principles agent is synergy.
2. herbicidal effect behind the bud
With unifacial leaf-and the seed or the stem tuber of broadleaf weed place the plastic basin that fills sand loam, topped and be placed on the greenhouse experiment cultivation down that helps growing with soil.The potted plant cultivation of weeds in paddy field, the water surface in the nurturing period basin maintain more than the soil layer surface 2 centimeters.After planting 3 weeks were grown to the medication processing during phase of 3 leaves when test plant.With the wetting powder of combination of active principles agent of the present invention or missible oil and as the corresponding formulation that contains single active ingredient of parallel test, be diluted with water to the green portion of the medicine liquid spray plant that is equivalent to about 300-600 liter/hectare by different dosage, test plant in the greenhouse under the best growing condition 3-4 Zhou Houyu not the contrast handled of medication compare, estimate the herbicidal effect of each preparation with visual method.For rice plant or weeds in paddy field, active ingredient directly can be added in the irrigation water (can use with similar method) or be sprayed onto medicament on the plant or in the irrigation water for granule.Medicament of the present invention uses as post-emergence herbicide, has good wide spectrum except that herbicidal effect for broad-leaved with important economic implications and Gramineae ruderal.Analyze according to Colby formula result of calculation, medicament of the present invention has synergistic effect.
Sand-grass grand (B8) and IC940 (B12) are for the safener effect example of anilofos:
Rice plant is planted in the plastic basin that contains sand, in the greenhouse, cultivates to 2.5 leaf phases.Whole test in the phase in the basin depth of water maintain more than the soil layer surface 3 centimeters.
When handling, be that suspension or the emulsion with each single agent of the present invention and combination agent dilute with water is added in the potted plant water surface by the mode of watering with the present invention.
In medicinal processing about 3 weeks of back, judge the extent of injury of rice plant by the fresh weight of determining the test plant stem.
Comprise resulting result of the test in the table of back and according to the desired value of Colby formula.Cited data clearly illustrate that, are not only that sand-grass is grand, and IC940 reduced by anilofos very significantly to the phytotoxicity that rice plant causes, that is to say that these two weed killer herbicides have the safener effect of prophesy for anilofos.For all combination agent, its desired value that calculates according to the Colby formula all significantly is lower than the practical measurement value of each combination agent.
The Colby calculated value of the synergy of weed killer herbicide and antagonism:
Colby formula: E=H 1 *H 2/ 100
