Abstract
The present invention relates to a herbicide composition, the active components of which comprise a compound with a structural formula I and at least one of 2-chlorine-4-ethylamino-6-isopropylamino-1, 3, 5-triazine(atrazine), 2-chlorine-4-(1-cyano-1-methyl lethylamino)-6-ethylamino-1, 3, 5-triazine(terbutylazine), alpha-chlorine-2+['], 6+[']-diethyl-N-methoxymethyl acetanilid (alachlor) or a 2-chlorine-N-(2-ethyl-6-methylphenyl)-N-(2-methoxy-1-methylethyl) acetamide (metolachlor) compound. When low dose, annual weeds and perennial weeds can be completely controlled, and the herbicide composition does not have phytotoxicity to grains.
Description
The present invention relates to a kind of Herbicidal combinations, its active ingredient is included in the compound of the usefulness following structural I representative that hereinafter is referred to as compound (I),
Be selected from 2-chloro-4-ethylamino-6-isopropylamino-1 with at least one, 3,5-triazine (common name: atrazine (atrazine)), 2-chloro-4-(1-cyano group-1-methyl ethylamino)-6-ethylamino-1,3, the 5-triazine (common name: bladex (cyanazine)), 2-chloro-2 ' 6 '-diethyl-N-methoxy antifebrin (common name: alachlor (alachlor)) and 2-chloro-N-(2-ethyl-6-aminomethyl phenyl)-N-(2-methoxyl group-1-Methylethyl) acetamide (common name: compound isopropyl methoxalamine metolachlor).
To the research and development of weed killer herbicide, various chemicals have been dropped into actual the use by for many years, in the work of control weeds or increase crop yield, can save the labour at these weed killer herbicides aspect agricultural or the gardening.Even at present, the new chemicals that exploitation has a better weeding characteristic remains and needs.Particularly, to being used for the agricultural and the weed killer herbicide of gardening, wish that it optionally controls the weeds object when low dosage, and crop is not had phytotoxicity, but existing chemicals may not necessarily satisfying this requirement.
Disclosed compound (I) in the interim patent publication No. 208977/1985 of Japan, when low dosage and the weed killer herbicide of prior art relatively show good herbicidal effect, and crop such as cereal, wheat etc. are had tight security.It not only shows good effect to annual weed and annual broadleaf weed, and perennial weed is also had very strong effectiveness.Therefore, it has very big using value.
In addition, compare with compound (I), the atrazine that prior art is known, bladex, alachlor and metolachlor are used for for example barnyard grass (Echinochloa crus-galli) of annual weed with higher dosage, green foxtail (Setaria Viri-dis), big yard grass (Digitaria sanguinalis) etc., and annual broadleaf weed.Thus, the anti-medicine of these chemicals and the broad leaved weed and the perennial weed that are difficult to these chemicals controls are increased, so need improve this.
The research that the present inventor did is intended to increase the herbicidal effect of compound (I), found that conventional atrazine, bladex, alachlor, metolachlor and the compound (I) that uses also used, can not only make the herbicidal effect adduction of each compound, and the collaborative effect of killing weeds appears, so finished the present invention.
Use is according to composition of the present invention, and synergy is strong, just can control annual weed and perennial weed fully and cereal is not had phytotoxicity when low dosage, and therefore effectiveness of the present invention is very big.And, might reduce the dosage of atrazine in the present composition, bladex, alachlor and metolachlor by using said mixture, effect of the present invention is good.
In addition, Herbicidal combinations of the present invention grows preceding or to grow post processing all effective in weeds, therefore by to soil treatment or to stem and soil all handle can both obtain efficient.And, except cereal, also can be used for various crops, be used for other farmland and gardening Tanaka simultaneously as cultivation farmland, orchard and uncultivated area such as stadium, vacant lot, backwoods, little flower garden, the control of various weeds such as railway limit, the present invention can show great economic benefit in the control weeds.
According to prescription of the present invention, generally each part weight atrazine, bladex, alachlor, metolachlor contain the compound (I) of 0.001 to 50 part of weight, yet can be different according to the relative activity of each component.
In many examples, when the ratio of compound (I) is lower than the ratio of other weed killer herbicide, for example, per by weight 1 part of atrazine, bladex, alachlor or metolachlor then can obtain the mixed herbicide of the present invention of optimum efficiency with the compound (I) of 0.001 to 0.5 part of weight.
The dosage of this mixture of using depends on many factors, and the kind of the plant object that for example making grows is suppressed says that generally 0.01 to 10 kilogram of active component/hectare may be suitable.The personnel that one's own profession is skilled in technique can need not carry out many experiments according to a kind of routine test of standard and just can determine a kind of suitable usage ratio at an easy rate.
The present composition preferably should adopt the composition forms that is mixed mutually by active ingredient and a kind of carrier that contains solid or liquid diluent.Said composition preferably contains a kind of surfactant in addition.
When using the present composition to make weed killer herbicide, generally it can be mixed mutually with a kind of suitable carriers, for example, a kind of solid carrier such as clay, talcum powder, bentonite, diatomite etc.; Or a kind of liquid-carrier such as water, alcohols (methyl alcohol, ethanol etc.), arene (benzene,toluene,xylene etc.), halogenated hydrocarbon, ethers, ketone, ester class (ethyl acetate etc.), amide-type (dimethyl formamide etc.).Said composition can contain a kind of emulsifier, wetting agent, dispersant, adhesive, bleeding agent, spreading agent, stabilizing agent etc., and can be any formulation drop into actual the use, missible oil for example, water-soluble missible oil, wetting powder, pulvis, granule, suspension concentrate etc.
The Synergistic herbicidal effect of this Herbicidal mixtures is soluble as follows: promptly each reactive compound can show separately effect in activity of weeding in many examples.In this example, the simple summation (activity of expection) of activity is big separately than these two kinds of compounds for the activity of weeding that obtains by the combination of two kinds of reactive compounds, and this just is called synergy.The expection activity that obtains from two kinds of weed killer herbicide particular combinations can be calculated as follows (referring to Colby, the collaborative and antagonistic effect of the calculating weed killer herbicide compound of S.R., " Weed ", 15 volumes, 20 to 22 pages, 1967)
E＝α+β- (α.β)/100
α: the inhibition growth percentage when using with the weed killer herbicide A of a kilogram/hectare expression;
β: the inhibition growth percentage when using with b kilogram/hectare weed killer herbicide B;
E: the expection when using with a+b kilogram/hectare weed killer herbicide A+B suppresses growth percentage.
Like this, when observed effect was bigger than intended effect, this compound showed synergy.
By following relevant example, will be to the present invention's detailed narration of making comparisons, however compound among the present invention, preparation consumption and dosage form etc. are not only limited to these examples.
