Description

A kind of bactericidal composition that contains kresoxim-methyl and fluorine bacterium azoles
Technical field
The invention belongs to technical field of pesticide, relate to a kind of application of bactericidal composition on the vegetables fruit diseases that contains kresoxim-methyl and fluorine bacterium azoles.
Technical background
Kresoxim-methyl (kresoxim-methyl) is the methoxy acrylic bactericide of BASF Aktiengesellschaft's exploitation.Molecular formula: C 18H 19NO 4, chemical name: methyl (E)-2-methoxyimino-2-[2-(0-toloxyl) phenyl] and acetate.
Kresoxim-methyl belongs to the mitochondrial respiratory inhibitor, be a kind of wide-spectrum bactericide, and the lasting period is long, and most of diseases that pathomycetes such as Ascomycetes, Basidiomycetes, Fungi Imperfecti and oomycetes subclass are caused have protection, treat and root out activity.
Fluorine bacterium azoles (triflumizole) is a kind of sterol demethylation inhibitor, and by Japanese Cao Da company development product, molecular formula is C 15H 15F 3Cl N 3O, chemical name are (E)-4-chloro-α, α, α-three fluoro-N-(1-imidazoles-1-base-α-third oxygen ethylidene) neighbour-toluidines fluorine bacterium azoles.
The protection of fluorine bacterium azoles tool, treatment and eradicant action are the systemic fungicides of wide spectrum, and the Erysiphaceae on vegetables and the fruit, Fusarium are had activity, are used to prevent and treat powdery mildew, rust, scab of wheat class, vegetables, fruit tree etc.
No matter be kresoxim-methyl, fluorine bacterium azoles or other efficient germicides, long-term use separately makes disease develop immunity to drugs easily, causes problems such as dosage increasing, preventive effect reduction, lasting period shortening, is unfavorable for the environment sustainable development.The active ingredient of different action principles is carried out composite, is to delay the disease method commonly used that develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.Kresoxim-methyl belong to two kinds of mechanisms of action with fluorine bacterium azoles and the mode of action different, mutually compositely can not produce conflict, good synergistic effect is arranged within the specific limits.And composite about kresoxim-methyl and fluorine bacterium azoles do not see relevant report at present at home and abroad as yet.
Summary of the invention
Purpose of the present invention proposes a kind of have synergistic effect, use cost is low, preventive effect the is good bactericidal composition that contains kresoxim-methyl and fluorine bacterium azoles.
The present invention is achieved through the following technical solutions:
A kind of bactericidal composition that contains kresoxim-methyl and fluorine bacterium azoles, wherein kresoxim-methyl and fluorine bacterium azoles percentage by weight are 1~60: 40~1.
