Description
Technical field
The present invention relates to the composition pesticides more particularly to one kind of a kind of prevention and treatment plant epiphyte or bacterial disease to contain quinoline
The bactericidal pesticide composition and preparation method thereof with synergistic effect of quinoline copper and metrafenone compounding, the invention further relates to this
Application of the composition pesticide in prevention and treatment plant epiphyte or bacterial disease, belongs to bactericidal pesticide composition field.
Background technique
Metrafenone (metrafenone) is the Benzophenone class fungicide of BASF exploitation, is a kind of broad spectrum activity interior suction sterilization
Agent has good protection and therapeutic effect to multiple diseases caused by basidiomycetes and sac fungus, and has certain stifling work concurrently
With wheat crops powdery mildew, rust, smut, smut of maize etc. can be effectively prevented, but inactive to oomycetes and bacterium.
Its mechanism of action is to inhibit the biosynthesis of ergosterol, can cause the growth of fungal cell wall rupture and mycelia.
Copper 8-hydroxyquinolinate be a kind of wide spectrum, efficiently, the Chelating state organic copper fungicide of low toxicity, to crop fungi, bacterial disease
All have it is excellent prevent, treat effect, have both the double sterilization effect of organic quinolines and copper agent, target site is more, more
Secondary to be not easy to produce resistance using germ, efficient to conventional sterilization agent resistant strain, the medicament lasting period is long.At present in production, quinoline
Copper is mainly used in prevention and treatment tomato late blight, bacterial canker, capsicum epidemic disease, canker, shot hole, downy mildew, cucumber downy mildew
Disease, bacterial leaf spot, the peronospora tabacina of lichee, water melon frost mildew, anthracnose, Acidovorax Avenae Subsp. Citrulli, late blight of potato etc.
Bacterium or fungal disease.
The difficulty of prevention and cure of plant disease is increasing at present, on the one hand, with the change of pattern of farming, melon fruits and vegetables etc.
Industrial crops and field crop cultivated area gradually expand, and disease occurrence degree, generation quantity are improved, in the upper hardly possible of prevention and treatment
Degree increases；On the other hand, the resistance of pathogen selects to rise year by year under pressure in lasting medicament, and the control efficiency of single dose is beaten greatly
Discount, control of plant disease are faced with significant challenge.It would therefore be highly desirable to need to develop it is a kind of compounded by Multiple Pesticides active constituent and
There is the composition pesticide of significant collaboration prophylactic-therapeutic effect for plant disease, is generated with delaying drug resistance, reduce amount of application, reduce prevention and treatment
Cost.
Summary of the invention
An object of the present invention is to provide the pesticide complex composition that a kind of plant disease has significant collaboration prophylactic-therapeutic effect；
