Abstract
The invention discloses a weeding composition containing topramezone. The active ingredients of the weeding composition are the topramezone, cyanazine and a cyanophenyl herbicide; the cyanophenyl herbicide is one of bromoxynil octanoate and bromoxynil; 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 cyanophenyl herbicide in the composition is 0.1%-50%, with the balance of pesticide auxiliaries. The weeding composition containing topramezone can be prepared into one of suspension, oil suspension, wettable powder and water dispersible granule; the weeding 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 a kind of Synergistic Herbicidal combinations taking benzene pyrazoles humulone, cyanazine, benzene nitrile herbicide (one in bromoxynil octanoate or Brominal) as active ingredient.
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 absorbs by plant root and upwards conduction, 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.
Benzene nitrile herbicide is contact killing type weed killer herbicide, after being absorbed by grass cutting blade, only can carry out limited conduction, main inhibited photosynthesis, impel blade chlorisis and produce withered spot, be mainly used in preventing and treating wheat, corn field annual broadleaf weed Ru pivot hold, black nightshade, Siberian cocklebur, field bindweed, dayflower, amaranth, knotweed, lamb's-quarters etc., in soil, the half life period is 15 days, to succession crop safety.
The inventor conducts in-depth research benzene pyrazoles humulone, cyanazine, benzene nitrile herbicide (one in bromoxynil octanoate or Brominal) mixture, find that benzene pyrazoles humulone, cyanazine, benzene nitrile herbicide (one in bromoxynil octanoate or Brominal) mixture have Synergistic response, especially to thorn amaranth (Amaranthus spinosus L.), pivot holds (Polygonum aviculare) obvious synergistic effect.
The mixture of benzene pyrazoles humulone, cyanazine, benzene nitrile herbicide (one in bromoxynil octanoate or Brominal) and application are without relevant report.
Summary of the invention
