Description

A kind of Herbicidal combinations

Technical field

The invention belongs to pesticide field, more particularly to a kind of Herbicidal combinations and a kind of undesirable plant growth of control Method.

Background technology

World food production is annual because disease, worm, crop smothering loss are huge, and the whole season of growth of crop can nearly all be subject to each The infringement of weeds is planted, Weed infestation is also the key factor for restricting crop yield.Therefore, the preventing and treating of agricultural weed is always agriculture It is concerned about the most and important problem in industry production.

Protect weeds and other vegetation infringement of the crops from suppressing crop growth be in agricultural it is lasting occur ask Topic.To solve the problem, the chemicals and chemicals of many control weed growths are used in business.

Paddy rice is one of world's staple food crop, in the world nearly half population, including almost whole East Asia and Southeast Asia Population, be food all with rice, production is also that most important grain is made in China paddy rice throughout each continent in addition to the South Pole Thing.China's rice growing area accounts for the 1/4 of national cereal crops, and yield then accounts for more than half.No matter cultivated area and yield, All ranked first in China cereal crops.

The preventing and treating of agricultural weed is always care and important problem the most in agricultural production.The whole season of growth of crop Can nearly all be endangered by various weeds.The all rice workspaces of China always have a large amount of weeds, and weeds in paddy field species is very Many, various regions are different because of the factor weeds such as weather, soil species, maximum with harm with barnyard grass occurring area in these weeds, also There are the hazard areas such as difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed, bog pondweed, Monochoria korsakowii and the order of severity to take second place.

Halosulfuronmethyl (Halosulfuron-methyl, CAS NO.100784-20-1) belongs to sulfonylurea herbicide, pure Product are white powdery solids, and 175.5-177.2 DEG C of fusing point is insoluble in water, in most solvents such as n-hexane, acetone, dichloromethane Solubility in alkane, toluene, ethyl acetate equal solvent is also smaller.Halosulfuronmethyl is the chloro- 5- of 3- [[[(4,6- dimethoxys -2- Pyrimidine radicals) amino] carbonyl]] amino] sulfonyl] -1- methyl isophthalic acid H- pyrazoles -4- carboxylate methyl esters adopted name.Halosulfuronmethyl It is sulfonylurea rice field selective inner-adsorption conduction-type herbicide.Halosulfuronmethyl is mainly absorbed by root system, can also be passed through Cauline leaf absorbs, and is shifted rapidly in weeds plant body, suppresses weed growth, and weeds are gradually dead.The weeding of halosulfuronmethyl is lived Property is described in The Pesticide Manual, Fourteenth Editioni, 2006.Halosulfuronmethyl control paddy rice, jade Many broad-leaveds and nut nutgrass flatsedge in rice, sorghum, sugarcane, nut and turf.

The use of chemical herbicide is one of important symbol of agricultural modernization, and in recent years, the sales volume of herbicide increases year by year Plus, administration area also expands year by year.But, as the large area of numerous herbicide kinds is persistently used, many problems are produced, For example Weed Resistance problem starts to show especially, and the resistance problem of especially elder weed is especially prominent；In addition, herbicide single dose effect side Formula is single, the lasting period is short etc..Therefore, presently, there are weeding scope wide, selective strong and less to herbicide resistance pressure The active demand of release weedicide and combinations thereof.

But, as numerous herbicide kinds are persistently used in rice terrace large area, also produce the problem of many：(1) it is miscellaneous Careless resistance is protruded, wherein more being protruded the resistance of the herbicides such as propanil, butachlor with barnyard grass, also sedge weed is to sulphonyl The resistance problem of carbamide herbicides also engenders；(2) elder weed and perennial weeds harm turns into major issue, particularly Above the average age for marriage barnyard grass and Cyperaceae perennial weeds are more prominent；(3) effect of herbicide kind is single, and the lasting period is short.

In some cases, have shown that in combination more effectively, this claims herbicidal active component compared with being administered alone It is " synergy ".Synergy is two or more factor interactions so that effect ratio is based on applying respectively upon combination It is good with the effect desired by the response of each factor.

CN103392724A discloses a kind of cassava field herbicide composition for preventing and treating the purposes of the rhizome of nutgrass flatsedge, and described removes Careless agent composition be by halosulfuronmethyl, Oxyfluorfen and acetamide-group herbicides for active component ternary combinations of herbicides Thing, acetamide-group herbicides are the one kind in butachlor, propisochlor, S-metolachlor.

Specific embodiment

Protect crops from weeds and other vegetation infringement of crop growth always be in agricultural it is lasting occur ask Topic.To help against the problem, the researcher of synthesis chemical field has prepared and various has effectively controlled this obnoxious growth Chemicals and chemicals.The chemical herbicide of many types is disclosed in the literature, and a large amount of chemical herbicides exist Used in business.

The combination of active principles of different agricultural chemicals is made mixture, is to develop and develop novel pesticide and preventing and treating at present agriculturally A kind of effective manner of resistant weed.After the pesticide activity component combination of different cultivars, three kinds of type of action are typically exhibited： Summation action, synergistic effect and antagonism.But which kind of effect be specially, it is impossible to predict.Surprisingly, the group of active component Conjunction has exceeded the desired additive effect to the weeds to be controlled in principle, and therefore particularly expand both ways this two Plant the sphere of action (that is, showing SA) of active component：First, the rate of application of single compound is reduced and kept simultaneously Good exposure level；Secondly the independent material in the range of low rate of application has become useless from the point of view of agronomic point In the case of, composition obtains high-caliber Weeds distribution；Kind, the preventing and treating that other composition for preventing and controlling is not controlled also are to single Herbicide or various herbicide tolerants or resistant kind, reduced using phase extension and/or the required number of times that is administered alone； And for user, obtain the control of weeds system advantageously in economic and ecology.

Super plus and (=collaboration) effect can be produced during the combined administration of component A and B.The synergy should be able to reduce each work Property the rate of application of material, the drug effect improved under identical rate of application, preventing and treating species, the extension administration period that cannot still prevent and treat so far, The number of times being administered alone needed for reducing.Therefore for user, be economically with weeds opposed body more favourable in ecology System.This activity can especially reduce amount of application, control broader spectrum of broad-leaved section, grass family, sedge weed, compensate for confrontation Property weed population active leak, rapider and more reliable activity, the longer lasting period, applying only once or several times can be complete Control noxious plant and extend the working life of active component in combination.

Above-mentioned characteristic is needed so that crops break away from the competition of undesirable plant in weeds in field preventing and treating, and/or Increase yield.The combination of instant component A and B is significantly beyond prior art in terms of above-mentioned characteristic.

The invention provides a kind of Herbicidal combinations, its active component is made up of component A and B；The weight of the component A and B Amount proportioning is 1:1-1:100, preferably 1:1-1:50, more preferably 1:1-1:40, it is further preferably 1:5-1:30, more preferably It is 1:5-1:25, more preferably 1:5-1:20, more preferably 1:1-1:15, it is further preferably 1:1-1:10.

The weight proportion of component A and B in the present invention for example can also be 1:1、1:5、1:10、1:15、1:20、1:25、 1:30、1:35、1:40、1:45、1:50、1:55、1:60、1:65、1:70、1:75、1:80、1:85、1:90、1:95、1:100。

It has unexpectedly been discovered that, compared with the rate of application of individual compounds, the combination of component A and B equal to or it is low The synergy to Weeds distribution is shown when the rate of application, especially to barnyard grass (Echinolchloacrus-galli； ECHCG), China Sprangletop (Leptochloa chinensis；), LEFCH yellow nut nutgrass flatsedge (yellow nutsedge) (Cyperus esculentus；CYPES), difformed galingale herb (Cyperus difformis L), black nightshade (Solanum nigrum L.), Tong fiber crops (Abutilon theophrasti Medic), acalypha copperleaf (AcalyphaaustralisL), firefly Lin (Scirpus Juncoides Roxb), the control of Waterplantain (Alisma plantago-aquatica Linn.) show that obvious collaboration is made With.

The rate of application of component A can change in a wide range, such as in 0.1g to 200g A.I./ha (hereinafter, A.I./ha Represent " active material/hectare "=reactive compound meter based on 100% purity).With the administration of 0.1g to 100g A.I./ha When rate is applied, when prior to seeding, before plantation or before bud and during middle use halosulfuronmethyl after bud, it has relatively wide waits to prevent The noxious plant spectrum controlled, such as halosulfuronmethyl can be used for a lot in control paddy rice, corn, sorghum, sugarcane, nut and turf Broad-leaved and nut nutgrass flatsedge.

The rate of application of component B can change in a wide range, for example 1g to 2000g A.I./ha, and it has relatively wide Noxious plant spectrum to be prevented and treated.

Depending on the suitable proportions of component A and B for example can be by reference to the rate of application of mentioned single compound. In Herbicidal combinations of the invention, rate of application can be generally reduced.In Herbicidal combinations of the invention, the weight proportion of A and B is 1:1-1:100。

Preferably, the weight proportion of component A and B is 1:1-1:50.
