Description
Technical field
The present invention relates to a kind of oxine-copper composite bactericide, belong to the disinfectant use in agriculture technical field.
Background technology
Copper 8-hydroxyquinolinate is novel organic copper preparation, is generated by oxine and copper sulphate reaction.Organic quinoline and mantoquita have the double sterilization activity, the G-protein synthesis that can suppress early stage cellular expression, suppress the metabolism of germ spore, the control cell divides once more and breaks up, it is active to have the multiple spot contact again concurrently, the pathogen spore that utilizes chelated copper to be sprouted absorbs, and directly kills the steamed stuffed bun cell in pathogen inside, thereby reaches the effect of preventing and curing diseases.Crop all had by fungi, bacterial multiple diseases kill significantly and inhibitory action, especially the downy mildew that caused by Oomycete, late blight etc. are had excellent control efficiency.
The spirit of Evil frost, metalaxyl, Propamocarb, white urea cyanogen, dimethomorph, pyraclostrobin, cyanogen frost azoles, Fluoxastrobin, fluorine pyrrole bacterium amine, mandipropamid An, oxazole bacterium ketone all are medicaments commonly used of preventing and treating the downy mildew bactericide in producing.Owing to use throughout the year, the existing pesticide resistance report of above various medicaments causes effect to descend, and with copper 8-hydroxyquinolinate and several bactericide compounded use, has very significant synergistic effect, can delay pesticide resistance, improves the control efficiency to cucumber downy mildew.
Copper 8-hydroxyquinolinate is Yu the situation of composite uses such as the spirit of Evil frost, metalaxyl, Propamocarb, white urea cyanogen, dimethomorph, pyraclostrobin, cyanogen frost azoles, Fluoxastrobin, fluorine pyrrole bacterium amine, mandipropamid An, oxazole bacterium ketone awaits further research.
