Abstract
The application relates to the technical field of agricultural herbicides, and particularly discloses a high-efficiency herbicide for low temperature and a preparation method and application thereof. The application discloses a high-efficiency herbicide for low temperature, which comprises the following components in parts by weight: 5-11 parts of flumioxazin, 0.2-0.8 part of glyphosate, 0.05-0.15 part of metasulfuron, 0.4-0.8 part of auxiliary agent, 0.05-0.09 part of phosphoric acid substance and 480-520 parts of solvent; the auxiliary agent comprises the following components in percentage by weight: 1-7, and mixing the sulfobetaine and the isoundecylenic alcohol polyoxyethylene ether; the phosphoric acid substance is selected from one or two of amino trimethylene phosphonic acid, ethylene diamine tetramethylene phosphonic acid, hydroxy ethylene diphosphonic acid and diethylene triamine pentamethylene phosphonic acid. The herbicide obtained by the technical scheme provided by the application has better efficacy and wider herbicide controlling spectrum.
Description
Technical Field
The application relates to the technical field of agricultural herbicides, in particular to a low-temperature efficient herbicide and a preparation method and application thereof.
Background
At present, most herbicides on the market can exert good weeding effect under a higher temperature environment, which limits the use of the herbicide in low-temperature seasons such as early spring or late autumn.
In order to solve the weeding problem in the low-temperature environment, methods of increasing the using concentration of herbicide or adding a synergistic agent are generally adopted, but the methods tend to increase the cost.
Therefore, the method has important significance in researching how to realize the high-efficiency and low-cost weeding effect in a low-temperature environment.
Disclosure of Invention
In order to solve the technical problems, the application provides a low-temperature efficient herbicide and a preparation method and application thereof.
The application provides a high-efficiency herbicide for low temperature, which comprises the following components in parts by weight: 5-11 parts of flumioxazin, 0.2-0.8 part of glyphosate, 0.05-0.15 part of metasulfuron, 0.4-0.8 part of auxiliary agent, 0.05-0.09 part of phosphoric acid substance and 480-520 parts of solvent;
the auxiliary agent comprises the following components in percentage by weight: 1-7, and mixing the sulfobetaine and the isoundecylenic alcohol polyoxyethylene ether;
the phosphoric acid substance is selected from one or two of amino trimethylene phosphonic acid, ethylene diamine tetramethylene phosphonic acid, hydroxy ethylene diphosphonic acid and diethylene triamine pentamethylene phosphonic acid.
The applicant of the application discovers that when flumioxazin, glyphosate and sulfometuron-methyl are used as active ingredients, the synergistic effect on weed control is high, the influence of weeds on fields can be effectively avoided, and the types of weeds can be controlled and the weed control spectrum of the herbicide can be improved by compounding the three substances; the three herbicides of flumioxazin, glyphosate and metasulfuron are compounded according to the specific weight parts, and the weight ratio is 1-7:1-7, and adding phosphoric acid substances to prepare the low-temperature efficient herbicide, and has synergistic weeding effect on goosegrass, erigeron breviscapus, rhizoma cyperi and other weeds, namely the herbicide obtained by the technical scheme provided by the application has better efficacy and wider weeding spectrum.
In the technical scheme provided by the application, the flumioxazin is a cyclic imine low-toxicity herbicide which is absorbed by buds and leaves, can effectively inhibit protoporphyrinogen oxidase (an important enzyme in plant chlorophyll synthesis), and after the flumioxazin is treated, protoporphyrin is accumulated in the body of a sensitive plant, so that photosensitization and peroxidation of cell membrane lipid are caused, cell membrane functions and structures are irreversibly damaged, sensitive weed stems and leaves are necrotized after stem and leaf treatment, and death occurs after sunlight irradiation; the bud necrosis of sensitive weeds after soil treatment dies after short sunlight irradiation, is easy to degrade in the environment and is safe for aftercrop. Glyphosate is a non-selective, residue-free, biocidal herbicide, is very effective against many years of rooting weeds, and is mainly used for inhibiting enolpyruvylshikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate into phenylalanine, tyrosine and tryptophan, interfering protein synthesis and leading to death of plants. Glyphosate is absorbed by the stems and leaves and then transmitted to all parts of plants, and can prevent and kill more than 40 families of plants such as monocotyledonous and dicotyledonous plants, annual and perennial plants, herbaceous plants, shrubs and the like. After the glyphosate is buried in the soil, the glyphosate is combined with metal ions such as iron, aluminum and the like to lose activity, and the glyphosate has no adverse effect on hidden seeds in the soil and soil microorganisms. The sulfometuron-methyl can inhibit the synthesis of branched chain amino acid, so that the cell division of the growth end of a plant is inhibited, and the weed is prevented from growing to green-loss necrosis. The polynary phosphonic acid substances can improve the scale inhibition effect of the herbicide, have excellent chelating ability to a plurality of metal ions and the like, have good scale inhibition efficiency, and simultaneously can effectively improve the weeding effect of the herbicide by adding the proper phosphoric acid substances.

After treatment, the culture is carried out in a greenhouse, and the simulated low-temperature environment of the greenhouse is set as follows: the temperature is 5-10deg.C, the humidity is 75%, and the illumination/darkness is 14h/10h. The growth of the target weeds was observed periodically, and the comprehensive herbicidal activity was visually observed 20 days after the treatment.
And weighing fresh weight of the aerial parts, and evaluating the toxicity of the medicament on weeds according to the inhibition rate of target weeds. The ternary combination effect evaluation method refers to Golby method in the combined effect determination of the compounding in the pesticide indoor biological determination rule.
Fresh weight inhibition (%) = (fresh weight of control weed-fresh weight of treated weed dosed)/fresh weight of control weed x 100%.
The calculation formula of the Golby method mixing effect is as follows: e 0 = XYZ/10000, wherein X represents the measured fresh weight survival of herbicide a; y represents the actual measured fresh weight survival rate of herbicide B; z represents the measured fresh weight survival rate of herbicide C; e0 represents the theoretical fresh weight survival rate of the herbicide (A+B+C) after the compound use. According to Golby method, setting E as the actual measurement fresh weight survival rate after the combination of flumioxazin, glyphosate and metasulfuron, and when E 0 -E >10, indicating that the mixed herbicide produces synergistic effect; when E 0 -E < -10, the antagonism of the herbicide mixture is shown; when the E 0 -E value is within.+ -.10, this indicates that the compounded herbicide produces a additive effect.
