Abstract
The invention discloses a composition containing glyphosate and 2,4-dichlorophenoxyacetic acid, and a use thereof. The composition is characterized in that crop accepted auxiliary materials contain glyphosate and 2,4-dichlorophenoxyacetic acid. The composition has an obvious synergistic effect on gramineous weeds represented by crabgrass and an addition effect on broad leaf weeds represented by chenopodium album thus can be utilized as a non-selective herbicide. The composition has the advantages that 1, the composition is compounded from novel drugs and has the characteristics of strong efficacy and low usage amount; the composition has weed control effects concretely comprising an obvious synergistic effect on gramineous weeds and an addition effect on broad leaf weeds; and the composition realizes that when a dosage of each drug is reduced, good weed control effects are still obtained thus a weed control cost is reduced and adverse influences caused by large dose drugs on the environment are avoided; and 2, the composition has good control effects, a fast weed eliminating speed and a strong adaptability.
Description
Technical field
The present invention relates to a kind of composition that is used to prevent and kill off the weeds on the agricultural, relate in particular to a kind of composition pesticide that is applicable to control lady's-grass and lamb's-quarters.
Background technology
Glyphosate chemical name N-(phosphoric acid methyl) glycine, be inner sucting conduction type wide spectrum steriland herbicide, main by suppressing enol acetonyl shikimene phosphate synthase in the plant corpus, thereby suppress the conversion of shikimene, make synthetic being interfered of protein cause plant death to phenyl alanine, cruel propylhomoserin and tryptophan.Glyphosate absorbs by leaf and non-woody stem, conducts to each several part in the plant corpus, can prevent and kill off unifacial leaf and plant dicotyledonous, annual and section more than 40 such as perennial herb and shrub.
Though glyphosate is a kind of wide spectrum steriland herbicide, can remove most of weeds, specific activity to grassy weed is higher, but glyphosate is to broad-leaved preventive effect and bad, and 2, the 4-dichlorophenoxyacetic acid is higher to the specific activity of broad leaved weed, and is lower to the specific activity of grassy weed, particularly invalid to the grassy weed at advanced age.
Summary of the invention
Technical problem to be solved by this invention provides a kind of composition and application thereof that contains glyphosate and 2,4 dichloro benzene ethoxyacetic acid, to overcome the defective that prior art exists, satisfies the needs in relevant field.
Glyphosate and 2 of containing of the present invention, the composition of 4-dichlorophenoxyacetic acid, in the auxiliary material that crops can be accepted, contain glyphosate and 2, the 4-dichlorophenoxyacetic acid, wherein, glyphosate and 2, the part by weight of 4-dichlorophenoxyacetic acid is: glyphosate: 2,4 dichloro benzene ethoxyacetic acid=100: 1～100;
Preferred weight ratio is: glyphosate: 2,4 dichloro benzene ethoxyacetic acid=100: 3～50;
In the described composition that contains glyphosate and 2,4 dichloro benzene ethoxyacetic acid, the weight percentage of glyphosate and 2,4 dichloro benzene ethoxyacetic acid is the 10%-85% of composition total weight;
Preferably, the weight percentage of glyphosate and 2,4 dichloro benzene ethoxyacetic acid is the 30%-80% of composition total weight;
Described glyphosate and 2,4 dichloro benzene ethoxyacetic acid are mixed with the water soluble salt of glyphosate and 2,4 dichloro benzene ethoxyacetic acid in advance in application;
The described glyphosate water soluble salt that contains is selected from ammonium salt, sylvite, sodium salt, isopropyl amine salt or dimethylamine salt;
Described 2,4 dichloro benzene ethoxyacetic acid water soluble salt is selected from ammonium salt, sylvite, sodium salt, isopropyl amine salt or dimethylamine salt;
Described auxiliary material comprises more than one in solvent, surfactant or the filler;
Described solvent comprises one or more of water, methyl alcohol, ethanol, isopropyl alcohol, ethylene glycol, glycerine or dimethyl formamide;
Described surfactant comprises more than one in APG, ethyoxyl beef tallow amine or the alkylsulfonate;
Described filler is selected from more than one in sodium carbonate, potash, ammonium carbonate, carbonic hydroammonium, ammonium sulfate, potassium sulphate, ammonium chloride or the potassium chloride;
Those skilled in the art can select proper supplementary material as required, adopts method well known in the art, described preparation of compositions is become various formulations such as aqua, soluble powder or soluble granula.
The applicant finds, after glyphosate and 2,4 dichloro benzene ethoxyacetic acid are composite by a certain percentage, is that the grassy weed of representative has obvious synergistic effect to lady's-grass, to being that the broad leaved weed of representative has summation action with the lamb's-quarters, can be used as steriland herbicide.
The composition that contains glyphosate and 2,4 dichloro benzene ethoxyacetic acid of the present invention, its advantage shows:
1, brand-new composite reagent, drug effect is stronger, and dosage is few.Glyphosate and 2, behind the 4-dichlorophenoxyacetic acid composite reagent, its herbicidal effect has obvious synergistic effect to grassy weed, to having summation action on the broad leaved weed, the single agent consumption that reduces separately also can reach better effect, thereby reduced the weeding cost, the adverse effect of having avoided a large amount of medications to bring to environment.
2, preventive effect is good, weed eradication speed is fast, adaptability is strong.
