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, and because disease, worm, crop smothering loss are huge, the whole season of growth of crop can nearly all be encroached on by various weeds, and Weed infestation is also the key factor for restricting crop yield.Therefore, the preventing and treating of agricultural weed is always care and important problem the most in agricultural production.

It is lasting produced problem in agricultural to protect weeds and other vegetation infringement of the crops from suppressing crop growth.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 the almost population in whole East Asia and Southeast Asia, is food all with rice, is produced throughout each continent in addition to the South Pole, is also most important cereal crops in China paddy rice.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, weeds in paddy field species is a lot, 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 the hazard area such as difformed galingale herb, Monochoria vaginalis, flat stalk Fischer grass, moleplant seed, bog pondweed, Monochoria korsakowii and the order of severity are taken second place.

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

Bentazone（Bentazone）, chemical name is 3-（1- Methylethyls）- 1H-2,1,3- benzothiadiazine -4（3H）-one -2,2- dioxide, the general entitled Bentazone of English, its structural formula is：

Bentazone is the selective herbicide after seedling of contact killing type, for seedling stage cauline leaf process, is worked by blade contact.When being used in dry land, bentazone first passes through blade face infiltration and is transmitted to and suppresses photosynthesis in chloroplaset.When being used in paddy field, bentazone can be permeated by blade face can be transmitted to cauline leaf by root absorption again, strong to hinder weeds photosynthesis and water metabolism, cause nutrition hungry, make physiological function imbalance and lethal.Active ingredient is detoxified in tolerable crop body to the weak glycoconjugates metabolism of activity, and to crop safety, after dispenser 6 ~ 18 weeks, bentazone can be decomposed by the microorganisms in soil.It is mainly used in preventing and kill off cereal crop, cotton, peanut, soybean, sweet potato, tea place, careless pasture, rape and pea Tanaka Cyperaceae and broad leaved weed, to flat bar Fischer grass, Herba Cyperi Glomerati, cyperus iria, difformed galingale herb, rhizoma alismatis, needle spikesedge herb, firefly Lin, Monochoria vaginalis, Monochoria korsakowii, mexicana, bur beggar-ticks, water starwort, dragon's tongue, cyperus iria L. rhizoma scirpi, angustifolia arrowhead herb, bog pondweed, clearvers, shepherd's purse, field thistle, Siberian cocklebur, the rhizome of nutgrass flatsedge, acalypha copperleaf, lamb's-quarters, thorn amaranth and branch amaranth, to hold back the broad leaved weeds such as blue dish, grass of meadow rue, purslane and nutgrass flatsedge etc. effective.

CN102792957A discloses a kind of herbicidal composition for preventing and kill off farmland weed, with penoxsuam and halosulfuronmethyl as active component, for rice field management of weeds, slows down the generation of Weed Resistance, good to crop safety.

CN102934636A discloses a kind of Herbicidal combinations containing halosulfuronmethyl and florasulam, including active component, auxiliary agent and carrier, the active component is made up of halosulfuronmethyl and florasulam, the Herbicidal combinations synergy is obvious, expand herbicide controlling spectrum, the security to crop is improve, can prevent and remove various weeds in a wheat field and the like.

CN102265841A discloses a kind of Herbicidal combinations containing bentazone and cyhalofop-butyl, the Herbicidal combinations are with bentazone and cyhalofop-butyl as principle active component, the Herbicidal combinations are applied to rice terrace postemergence weed control, using with remarkable result particularly in grass family in preventing and kill off rice terrace and broad leaved weed.The Herbicidal combinations on the premise of drug effect is improve, delay Weed Resistance relative to single dose, and herbicidal spectrum is wide, and the lasting period is long, and all has security to paddy rice and succession crop.

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, and administration area also expands year by year.But, as the large area of numerous herbicide kinds is persistently used, produce many problems, such as Weed Resistance problem to start to show especially, the resistance problem of especially elder weed is especially prominent；In addition, the herbicide single dose mode of action is single, the lasting period is short etc..Therefore, presently, there are weeding scope wide, selective by force and to the active demand of the less release weedicide of herbicide resistance pressure and combinations thereof.

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

In some cases, have shown that in combination more effectively, this referred to as " acts synergistically " herbicidal active component compared with being administered alone.Synergy is two or more factor interactions so that upon combination effect than based on respectively apply each factor response desired by effect it is good.

Specific embodiment

It is lasting produced problem in agricultural to protect crops to be encroached on from the weeds and other vegetation of crop growth always.To help against the problem, the researcher of synthesis chemical field has prepared various chemicals and chemicals for effectively controlling this obnoxious growth.The chemical herbicide of many types is disclosed in the literature, and a large amount of chemical herbicides are used in business.

The combination of active principles of different agricultural chemicals is made mixture, is to develop at present and develop novel pesticide and prevent and treat a kind of effective manner of agriculturally 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 combination of active component has exceeded the desired additive effect to the weeds to be controlled in principle, and the sphere of action of both active components is therefore particularly expanded both ways（That is, SA is shown）：First, the rate of application of single compound is reduced and maintains good exposure level；Secondly in the case that the independent material in the range of low rate of application has become useless from the point of view of agronomic point, composition obtains high-caliber Weeds distribution；Also controlled kind, preventing and treating are not reduced other composition for preventing and controlling to single herbicide or various herbicide tolerants or resistant kind, 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.

Can be produced during the combined administration of halosulfuronmethyl and bentazone it is super plus and（=collaboration）Effect.Species, extension administration period, the number of times being administered alone needed for reducing that rate of application that the synergy should be able to reduce each active material, the drug effect improved under identical rate of application, preventing and treating cannot still be prevented and treated so far.Therefore it is economically to resist system with weeds more favourable in ecology for user.This activity can especially reduce amount of application, control broader spectrum of broad-leaved section, grass family, sedge weed, compensate for the active leak of antagonism weed population, rapider and more reliable activity, the longer lasting period, only once or several times apply the working life that can completely control noxious plant and extend active component in combination.

Above-mentioned characteristic is needed in weeds in field preventing and treating so that crops break away from the competition of undesirable plant, and/or increase yield.The combination of halosulfuronmethyl of the present invention and bentazone is significantly beyond prior art in terms of above-mentioned characteristic.

The present invention provides a kind of Herbicidal combinations, and its active component is made up of halosulfuronmethyl and bentazone；The halosulfuronmethyl and bentazone weight proportion are 1:1-1:100, preferably 1:1-1:50, more preferably 1:1-1:40, it is further preferably 1:1-1:30, more preferably 1:1-1:25, more preferably 1:1-1:15, more preferably 1:1-1:10.

The weight proportion of halosulfuronmethyl and bentazone 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.

Bentazone can exist in a salt form.

It has unexpectedly been discovered that, compared with the rate of application of individual compounds, the combination of halosulfuronmethyl and bentazone shows the synergy to Weeds distribution when equal to or less than the rate of application, especially to barnyard grass（Echinolchloacrus-galli; ECHCG）, China Sprangletop (Leptochloa chinensis;), LEFCH black nightshade（Solanum nigrum L.）, Tong fiber crops（Abutilon theophrasti Medic）, acalypha copperleaf（AcalyphaaustralisL）, yellow nut nutgrass flatsedge（yellow nutsedge）(Cyperus esculentus;CYPES control) shows obvious synergy.

Halosulfuronmethyl rate of application can change in a wide range, such as in 0.1g to 200g A.I./ha（Hereinafter, A.I./ha represents " active material/hectare "=reactive compound meter based on 100% purity）.When being applied with the rate of application of 0.1g to 100g A.I./ha, when prior to seeding, plantation before or bud before and bud after middle use halosulfuronmethyl when, there is relatively wide noxious plant to be prevented and treated to compose for it, and such as halosulfuronmethyl can be used to control many broad-leaveds in paddy rice, corn, sorghum, sugarcane, nut and turf and nut nutgrass flatsedge.

The rate of application of bentazone can change in a wide range, for example 1g to 2000g A.I./ha, there is relatively wide noxious plant to be prevented and treated to compose for it.

Depending on halosulfuronmethyl and the suitable proportion of bentazone 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 halosulfuronmethyl and bentazone is 1:1-1:100.

Preferably, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:50.

Particularly, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:40；

More special, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:30.

More special, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:25.

More special, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:15.

More special, the weight proportion of halosulfuronmethyl and bentazone is 1:1-1:10.

Herbicidal combinations of the invention can also include one or more other reactive compound that are different from halosulfuronmethyl and bentazone component and also serving as selective herbicide.

Herbicidal combinations of the invention can also include the various reactive compounds of other components, be selected from safener, fungicide, insecticide, acaricide, nematicide, bird repellent, soil conditioner, nutrient for plants (fertilizer) and structure different from halosulfuronmethyl and the herbicide and plant growth regulator of bentazone.

Evaluation to activity of weeding after the bud of Herbicidal combinations in greenhouse

Under greenhouse experiment, the seed of required test plants species is planted in seedling alms bowl.Using standard soil as cultivation matrix.When plant reaches the 3rd to four leaf periods, herbicide individually or is in combination processed into blade.Each treatment is repeated 4 times.

According to constant weight percentage reagent preparation：1st, halosulfuronmethyl；2nd, bentazone；3rd, halosulfuronmethyl+bentazone；.Afterwards by above-mentioned each reagent dilute with water, medicament dilution is obtained.

Investigation method：

Target damage symptoms and growth inhibition situation are estimated after test process 21d, and claims aerial part fresh weight, calculate fresh weight inhibition (%).

Evaluation to the mixed synergistic effect for applying middle display of two or more herbicidal active components is based in " CalculationSynergistic and Antagonistic Response of Herbicide Combinations”(Weeds 15/1 (1967), S.R.Colby) described in Colby ' s methods determine.

In formula, X be halosulfuronmethyl with certain dosage when alone to the fresh weight inhibition of target weeds.

Y be bentazone with certain dosage when alone to the fresh weight inhibition of target weeds.

E₀To the theoretical value of target weeds fresh weight inhibition during for halosulfuronmethyl and two kinds of pharmacy mix of bentazone.

To the measured value of target weeds fresh weight inhibition when E is halosulfuronmethyl and two kinds of pharmacy mix of bentazone.

If the actual control of weeds rate observed in biologic test（E）More than the desired value for using Colby ' s methods to be calculated（E₀）, then it represents that summation of the effect of Herbicidal combinations more than each agent effectiveness, it means that composition has synergistic effect.

The Herbicidal combinations of 1 halosulfuronmethyl of table+bentazone are to barnyard grass in greenhouse（21 days after）Synergistic activity

The Herbicidal combinations of 2 halosulfuronmethyls of table+bentazone are to difformed galingale herb in greenhouse（Cyperus difformis L）（21 days after）Synergistic activity

The Herbicidal combinations of 3 halosulfuronmethyls of table+bentazone are to China Sprangletop in greenhouse（21 days after）Synergistic activity

Table 1, table 2, the number of table 3 is it was demonstrated that the herbicide of the composition of halosulfuronmethyl+bentazone shows cooperative effect on Weeds distribution.
