Description
Technical field
The invention discloses a kind of agriculture chemical compounding bactericidal composition, especially a kind of Fluoxastrobin, difenoconazole and own azoles
The bactericidal composition of alcohol and its application.
Background technology
Fluoxastrobin, is methoxy acrylate (Strobilurin) class sterilization pesticide, and active compound appearance is off-white color to yellow
Solid（Content is higher, fineness is better, color is more shallow）, have the characteristics that efficiently, wide spectrum, mainly by with cell color on mitochondria
The sites Qo of plain b combine, and block the electronics transfer between cytochromes, the breathing of mitochondria is inhibited to play a role, destroy disease
The energy of bacterium synthesizes.The product is to almost all of mycota（Ascomycotina, Basidiomycotina, Mastigomycotina and partly know
Bacterium subphylum）Disease such as powdery mildew, rust, banded sclerotial blight etc. have good activity.
Difenoconazole is the interior suction wide-spectrum bactericide that safety is relatively high in triazole bactericidal agent, has protection and controls
Treatment acts on, and wide sterilization spectrum, lasting period are long, and difenoconazole can inhibit the wheat of fungi as all triazole bactericidal agents
The biosynthesis of angle sterol.Active compound is grayish white powdery object, and 78.6 DEG C of fusing point is widely used in the crops such as fruit tree, vegetables, can have
The diseases such as effect prevention scab, anthrachose of grape and white rot.
Hexaconazole, sterol demethylation inhibitors, active compound are ecru loose powder, to fungi especially Basidiomycota and
Disease caused by Ascomycota has the protection and therapeutic effect of broad spectrum activity.Hexaconazole is mainly by destroying and preventing the cell of germ
The biosynthesis of film important composition ingredient ergosterol causes cell membrane that cannot be formed, to keep germ dead, have interior suction,
Protection and therapeutic activity.
The study found that various plants germ produces resistance to Fluoxastrobin, continuous administration 2 times or more, to harmful organism
Control effect decreased significantly；And Fluoxastrobin is applied with after difenoconazole complex preparation, control effect is obviously improved.Cause
This, agriculture chemical compounding can not only delay harmful organism to the generation of pesticide drug resistance, be effectively protected natural enemy, and have new increasing
Effect acts on.Currently, have no Fluoxastrobin, difenoconazole and hexaconazole this three complex preparation related report.
