Abstract
The invention discloses a weed control composition containing glufosinate-ammonium and aquacide. The weed control composition containing glufosinate-ammonium and aquacide comprises pesticide auxiliaries, glufosinate-ammonium and aquacide, wherein the weight part ratio of the glufosinate-ammonium to the aquacide is (10 to 1)-(1 to 10); and the sum of the weight of the glufosinate-ammonium and the aquacide accounts for 5-80 weight percent in the weed control composition. The weed control composition disclosed by the invention has an obvious synergistic effect and is suitable for controlling weeds in the non-cultivated land, the dosage of the pesticides is reduced, the drug cost is reduced, the service life of the agents is prolonged, and the adverse effect of the pesticides on the ecological environment is reduced.
Description
Technical field
The invention belongs to technical field of pesticide, being specifically related to a kind of active ingredient is careless ammonium phosphine and diquat composition, and this combination significantly improves control efficiency, is applicable to ridge control of weeds.
Background technology
Grass ammonium phosphine (glufosinate-ammonium), belong to acid herbicides of seeing, it is glutamine synthetase inhibitor, have the non-selective contact weedicide of part systemic action, after dispenser in the short time, in plant corpus, disorder is sunk in ammonium metabolism, cytotoxic agent ammonium ion is accumulated in plant corpus, meanwhile, photosynthesis is seriously suppressed, and reaches weeding object.
Diquat (diquat), belong to non-selective contact killing type weed killer herbicide, slightly have a conductivity, can be absorbed rapidly by plant green tissues, in plant green tissues, Bipyridine compound is photosynthesis electron transfer inhibitor, the Bipyridine compound of reducing state is under photoinduction, oxidized very soon when aerobic exists, and forms hydrogen peroxide, the accumulation of this material makes plant cell film destroy, makes by medicine position withered and yellow.
It is the emphasis problem that agricultural science and technology worker pays close attention to that farmland weed science is administered always.Along with the impact of the pesticide control continuity year in year out of weeds chemistry, the agricultural chemicals not factor such as scientifical use agricultural chemicals, cause Weed Resistance day by day serious, cost accounting, difficulty increase.Meanwhile, due to the use agricultural chemicals of high strength, result in that Practice for Pesticide Residue in Agricultural Products exceeds standard, contaminated environment increases the weight of and the series of problems such as peasant's drug cost increase, be unfavorable for the sustainable development of agricultural.
Development is efficient, low toxicity, low-residual, the different mechanism of action, have again the complex preparation of synergistic function simultaneously, not only contribute to the generation delaying herbicide resistance, but also the service life of pesticide species can be extended, reduce using dosage, cost-saving, reduce the pollution to environment.The combination of the present inventor to careless ammonium phosphine and diquat conducts in-depth research, find that careless ammonium phosphine and diquat combine, in certain proportion, there is obvious synergistic function, in actual use simultaneously, outstanding control efficiency is had to weeds agriculturally, especially lady's-grass, grayish green multitude, special-shaped nutgrass flatsedge have obvious Synergistic to respond, and after further study, complete the present invention.
The present invention possesses the prospect of industrial applications, by certain technological means, can excipient be that aqua is convenient to agriculturally use.
Grass ammonium phosphine and diquat combination are used for preventing and kill off uncultivated area weeds without relevant report.
Summary of the invention
The object of the present invention is to provide a kind of Herbicidal combinations that there is synergistic function, expand the uncultivated area that herbicide is composed, use cost is low, drug effect is outstanding.
The technical scheme realizing the object of the invention is: for achieving the above object, the invention provides a kind of Herbicidal combinations, be made up of active ingredient grass ammonium phosphine and diquat and suitable insecticides adjuvant, the ratio of weight and number of grass ammonium phosphine and diquat is 10:1-1:10, preferred weight portion rate is 3:1-1:3, grass ammonium phosphine and the percentage by weight of diquat weight summation in Herbicidal combinations are 5%-80%, and all the other are allow in agricultural chemicals to use and acceptable insecticides adjuvant.
Described Herbicidal combinations according to well known to a person skilled in the art method, can be selected suitable insecticides adjuvant and carrier, being processed into aqua.
Described insecticides adjuvant is propane diols, diethylene glycol (DEG), urea, alkyl glycoside, empgen BB, fatty acid distribution of coconut oil diglycollic amide, lauryl sodium sulfate, neopelex, sodium butylnaphthalenesulfonate, sodium alkyl sulfonate, polyvinyl acetate, xanthans, gelatin, gum Arabic, aluminium-magnesium silicate, phenolic resins, CMC, sodium alginate, citric acid, succinic acid, maleic acid, fumaric acid, tartaric acid, oxalic acid, malonic acid, malic acid, succinic acid, hexanedioic acid, boric acid, phosphoric acid, benzoic acid, sulfamic acid, salicylic acid, glutamic acid, phenylacetic acid, nicotinic acid or sorbic acid, calcium stearate, dolomol, barium stearate, titanium dioxide, talcum powder, Stepanol MG, the one or more combination of polysorbate.
Described carrier is industrialization deionized water.
The processing method of Herbicidal combinations of the present invention: fully dissolve careless ammonium phosphine by industrialization deionized water; Add diquat to mix; The industrialization deionized water adding appropriate amount of addition agent and surplus mixes, and can obtain Herbicidal combinations of the present invention.
Herbicidal combinations provided by the invention, usually adopts the method for directed spraying to use, also can adopt other operation techniques agriculturally applied as required.
Compared with prior art, the invention has the advantages that:
1, Herbicidal combinations of the present invention has synergistic function, is used alone the control efficiency significantly improved weeds than single dose, expands herbicide spectrum, decreases Pesticide use amount, reduce use cost, alleviates pollution to environment
2, Herbicidal combinations of the present invention two kinds of active ingredient mechanisms of action are different, can delay the generation of herbicide resistance.
Embodiment
In order to make object of the present invention, technical scheme and advantage more short and sweet, the following specific embodiment of the present invention is described, but the present invention is only limitted to absolutely not these examples.The following stated is only the good embodiment of the present invention, only for describing the present invention, can not be interpreted as the restriction to scope of the present invention.It should be pointed out that all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Assays Example 1: careless ammonium phosphine and diquat mixture are to the Toxicity Determination of lady's-grass, grayish green multitude, special-shaped nutgrass flatsedge
Evaluate weed killer herbicide associated form (NY/T 1155.7-2006) according to Colby method, its formula is as follows:
