Abstract
The invention discloses a pesticide composition containing a triketone herbicide. The active ingredients of the pesticide composition include topramezone, cyanazine and the triketone herbicide; the triketone herbicide is one of mesotrione and sulcotrione; the weight percentage of the topramezone in the composition is 0.1%-40%, while the weight percentage of the cyanazine in the composition is 0.1%-30%, and the weight percentage of the triketone herbicide in the composition is 0.1%-50%, with the balance of pesticide auxiliaries. The pesticide composition containing the triketone herbicide can be prepared into one of suspension, oil suspension, wettable powder and water dispersible granule; the pesticide composition has the control effect obviously superior to that of each single ingredient on annual weeds in a cornfield, so that the dosage is reduced and the herbicide resistance of the weeds is retarded.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to that a kind of to take benzene pyrazoles humulone, cyanazine, three ketones weed killer herbicide (in mesotrione or sulphur humulone a kind of) be the Synergistic response composition pesticide of active ingredient, be mainly applicable to control of maize field and especially take mao matang (Digitaria chrysoblephara Fig.), field thistle (the corn field annual weed that Cirsium setosum (Willd.) is advantage weeds.
Background technology
Benzene pyrazoles humulone (topramezone), for cauline leaf inorganic agent after pyrazolone seedling, can be absorbed by root, young stem and leaf, by suppressing the 4-medical midbodies of para (ortho)-hydroxybenzoic acetone acid esters dual oxide enzyme (4HPPD) in plastoquinone biosynthesis, synthesizing of remote-effects carotenoid, disturb the synthetic and function of chloroplast, finally cause serious albefaction (due to chlorophyllous degraded), selectivity corn to height, is mainly used in preventing and kill off corn field annual gramineous weed and part broad leaved weed.
Cyanazine (cyanazine), is sym-trinitrobenzene corn herbicide, mainly by plant root, absorbs and the conduction that makes progress, and suppresses the photosynthesis of weeds, makes it withered.Its herbicide spectrum is wider, can prevent and kill off multiple annual gramineae and broad leaved weed.Be applicable to the dry crops such as corn, pea, broad bean, potato, sugarcane, cotton and prevent and kill off lady's-grass, barnyard grass, nutgrass flatsedge, amur foxtail, knotweed, lamb's-quarters, Cruciferae, pulse family weeds, especially corn is had to good selectivity (because there being removing toxic substances mechanism in Corn), some perennial weed is also had to certain inhibitory action.
Three ketones weed killer herbicide is systemics, by root system of plant and blade, absorb, and conduction in vivo, suppress hydroxyphenyl pyruvic acid dual oxide enzyme, cause the accumulation of tyrosine, the biosynthesis of plastoquinone and vitamin e stops, and then cause chlorophyllous content to decline, make plant meristematic tissue chlorosis produce albefaction death, can prevent and kill off annual broadleaf weed and part grassy weed, can seedling before after native list processing and seedling cauline leaf process, in soil, residual life, is shorter, to succession crop safety, three ketones weed killer herbicide main species has mesotrione and sulphur humulone.To benzene pyrazoles humulone, cyanazine, three ketones weed killer herbicide (in mesotrione or sulphur humulone a kind of), be mixed conducts in-depth research the inventor, find benzene pyrazoles humulone, cyanazine, three ketones weed killer herbicide (in mesotrione or sulphur humulone a kind of) the Synergistic response that has been mixed, especially mao matang (Digitaria chrysoblephara Fig.), field thistle (Cirsium setosum (Willd.)) are had to obvious Synergistic response.
Being mixed and applying current without relevant report of benzene pyrazoles humulone, cyanazine, three ketones weed killer herbicide (in mesotrione or sulphur humulone a kind of).
Summary of the invention
