Abstract
The invention relates to a herbicidal composition containing propyrisulfuron, cyhalofop-butyl and fenoxaprop-P-ethyl. The herbicidal composition contains active ingredients of propyrisulfuron, cyhalofop-butyl and fenoxaprop-P-ethyl, wherein the percentage by weight of propyrisulfuron in the herbicidal composition is 0.1%-30%, the percentage by weight of cyhalofop-butyl in the herbicidal composition is 0.1%-40%, and the percentage by weight of fenoxaprop-P-ethyl in the herbicidal composition is 0.1%-20%. The herbicidal composition provided by the invention has a synergistic effect, the effect of controlling annual weeds in a paddy rice field is obviously better than the effect when a respective agent is used alone, the herbicide controlling spectrum is expanded, the dosage is simultaneously reduced, the production of drug resistance of the weeds is delayed, and the environmental pollution is reduced.
Description
Technical field
The invention belongs to technical field of pesticide, be specifically related to the Herbicidal combinations that a kind of Synergistic that is active ingredient with promazine Sulfometuron Methyl and cyhalofop-butyl and fenoxaprop responds, be applicable to prevent and kill off paddy field annual weed.
Background technology
Promazine Sulfometuron Methyl (Propyrisulfuron), is a kind of selectivity broad-spectrum herbicide, has good preventive effect to the weeds of resistance to sulfonylurea herbicide, effective to above the average age for marriage barnyard grass, nutgrass flatsedge, broadleaved herb, can foliar spray, get rid of and execute.
Cyhalofop-butyl (cyhalofop-buty) is only kind paddy rice to tight security in fragrant phenoxy phenoxy propionic acid weed killer herbicide, the same with such other kinds, is also Uptake and translocation weed killer herbicide.By blade and the leaf sheath absorption of plant corpus, phloem conducts, and accumulates the meristem zone in plant corpus, resists acetyl-CoA carboxylase (ACCase), fatty acid is synthesized stop, the growth division of cell can not normally be carried out, and membranous system etc., containing fat structural deterioration, finally cause Plant death, weeds Mortality Ratio is absorbed into slower from cyhalofop-butyl, generally need 1-3 week, weeds symptom is after administration as follows: the tender shoots atrophy of four leaf phases, causes death.The Lao Ye change of two leaf stage is minimum, keeps green, is mainly used in preventing and kill off important grassy weed.Cyhalofop-butyl is efficient to moleplant seed, have certain preventive effect to low age barnyard grass, also can prevent and kill off, lady's-grass, Paspalum distichum, green foxtail, eleusine indica, amur foxtail etc., to sedge weed and broad leaved weed invalid.
Fenoxaprop (fenoxaprop-P-ethyl), belong to heterocyclic oxy group phenoxy propionic acid class weed killer herbicide, mainly by suppressing key enzyme one acetyl-CoA carboxylase of fatty acid synthesis, thus inhibit the synthesis of fatty acid, medicament by cauline leaf Assimilation and conductivity to the growing point of meristematic tissue and root, effect rapidly, within after dispenser 2-3 days, stop growing, 5-6 days lobus cardiacus chlorosis purpling looks, meristematic tissue browning look, blade is withered gradually, is the extremely strong cauline leaf inorganic agent of selectivity.
The present inventor is to promazine Sulfometuron Methyl, cyhalofop-butyl, fenoxaprop mixture conducts in-depth research, find promazine Sulfometuron Methyl, cyhalofop-butyl, fenoxaprop mixture has Synergistic to respond, especially to moleplant seed (Leptochloa chinensis), barnyard grass (Echinochloa crusgalli), lady's-grass (Digitaria sanguinalis), mao matang (Digitaria chrysoblephara), eleusine indica (Eleusine indica), green foxtail (Setaria viridis), bent grass (Agrostismatsumurae), Paspalum distichum (Paspalum paspaloides), Yunnan ditch millet (Paspalumdelavayi), hairy flowered paspalum (Paspalum dilatatum), Leersia Sw (Leersia hexandra), nit grass (Leptochloa panicea) has obvious Synergistic to respond.
Promazine Sulfometuron Methyl, cyhalofop-butyl, fenoxaprop composite without relevant report.
Summary of the invention
