Abstract
The invention discloses a sterilization composite whose effective activity components comprise flutriafol and kresoxim-methyl in a weight ratio of 1-40:80-5. Auxiliary agent and excipient are added into the effective activity components to prepare wettability powder, water-dispersion granule and suspending agent. The invention is mainly used in curing and preventing powdery mildew and cladosporium cucumerinum of vegetable and fruit trees.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on vegetables, fruit diseases that contains Flutriafol and kresoxim-methyl.
Technical background
Flutriafol (flutriafol) is the triazole bactericidal agent that American Cyanamid Company produces.Molecular formula: C16H13F2N30, chemical name: α-(2-fluorophenyl)-α-(4-fluorophenyl)-1H-1,2,4-triazole-1-ethanol.
Flutriafol belongs to triazole bactericidal agent, has interior absorption, in plant corpus, conducts, and disease is had protection and therapeutic action.Can prevent and treat the cereal crop powdery mildew, Helminthosporium, Puccinia, shell pin Pseudomonas pathogen also can be cooked seed treatment, prevents and treats soil-borne disease and seed-borne disease.The cereal powdery mildew there is special efficacy.
Kresoxim-methyl (zineb) is a kind of protectiveness organosulfureous fungicide.Molecular formula: C4H6N2S4Zn, chemical name: zinc ethylenebisdithiocarbamate.
Kresoxim-methyl is the protectant wide-spectrum bactericide that a kind of foliage spray is used, and many germs such as Pseudoperonospora cubensis, late disease bacteria and anthrax bacteria etc. are had strong action of contace poison.To plant safety; The active ingredient chemical property is more active, in water, is prone to be oxidized to different thiocyanation compound, to the cause of disease thalline contain-enzyme of SH base has had strong inhibitory effects; And the direct kill pathogens spore of ability; Suppress the germination of spore, stop in the germ invaded plants body, but very little to the mycelial lethal effect of cause of disease in the invaded plants body.Therefore, use kresoxim-methyl to prevent and treat disease and should grasp in the disease beginning and see that the phase carries out, just can obtain effect preferably.The drug effect phase of kresoxim-methyl is short, decomposes comparatively fast about 7 days of its longevity of residure at solar radiation and after absorbing airborne moisture.
At present, along with the increase of disease drug resistance, user's dosage, medication number of times also increase thereupon; But preventive effect descends year by year; Problem of environmental pollution is also more and more serious, and user's cost rises year by year, and proposing new preparation, to overcome present situation extremely urgent; But research and development novel pesticide consuming time oversize, cost is too high, unsatisfactory.Composite between the active ingredient of different sterilization mechanisms, be present modal method, both reduced user's cost, to the pollution of environment, also enlarge the control spectrum, improved drug effect.
At home and abroad also do not appear in the newspapers about Flutriafol and the composite bactericidal composition of kresoxim-methyl up to now.
Summary of the invention
The object of the invention proposes a kind of have synergistic effect, use cost is low, preventive effect the is good bactericidal composition that contains Flutriafol and kresoxim-methyl.
The present invention realizes through following technical scheme:
A kind of bactericidal composition that contains Flutriafol and kresoxim-methyl, wherein Flutriafol and kresoxim-methyl percentage by weight are 1～40: 80～5.
