The invention discloses a kind of composition pesticide of fluorine-containing bacterium mite ester and tetramycin, including usual auxiliaries, fluorine bacterium mite ester and tetramycin, the quality parts ratio of fluorine bacterium mite ester and tetramycin is 3:1~1:12, preferably than being 1:1~1:9, more preferably than being 1:3~1:6.Fluorine bacterium mite ester and there is synergistic effect to pathogen fungi such as monofilament powdery mildew (Sphaerotheca fuliginea (Schlecht) Poll.) after being compounded in certain proportion with tetramycin, is suitable for prevention by the fungus-caused crop disease of pathogen such as powdery mildew of cucumber, powdery mildew of strawberry.
Description
Technical field
The invention belongs to synergetic pesticide composition fields, and in particular to one kind containing active constituent fluorine bacterium mite ester and tetramycin
Composition pesticide.
Background technology
Fluorine bacterium mite ester, english common name：Flufenoxystrobin, test code number:SYP-3759 is a kind of methoxyl group
Acrylic bactericide, by the electronics transfer in Cytochrome B cl to cromoci, to inhibit the breathing of mitochondria.
The compound is used alone that cost is higher and easy Induced resistance generates, to reduce the service life.
Tetramycin (tetramycin) is the fermentating metabolism product of S. ahygroscopicus Wuzhou subspecies, wide sterilization spectrum, to flagellum
Disease fungus known to main kind of 26 kinds of bacterium, sac fungus and Deuteromycotina fungi etc. three has extremely strong killing effect.It is suitable
With the prevention of a variety of fungies, bacteriosis of various crops.Especially to powdery mildew of cucumber, fruit tree putrefaction disease spot defoliation, rice
Seasonal febrile diseases, root rot, cucurbits fusarium wilt, cotton verticillium wilt, jujube tree rust, fruit white rot of grape, Panax pseudoginseng black spot, tealeaves
The fungal diseases special efficacys such as gall of tea, forest rot disease, canker, bleeding disease, defoliation, woods seedling blight.
It is one of prevention most effective chemical means of phytopathogen using chemical agent；With the novel pesticide of not cross resistance
It is a good solution to carry out controlling plant diseases；But one novel pesticide of exploitation needs to screen a chemical combination up to ten thousand at present
Object, hundred million dollars of cost 1.2-1.5, the development cycle is 5-10, it is difficult to the speed that the upper pathogen caught up with develops immunity to drugs；It is other
Method such as crop structure adjustment, different pesticide rotations etc., in actual mechanical process, it is difficult to play apparent effect.
Develop new product fungicide is expensive, the period is long, and in contrast, exploitation is efficient, less toxic, low-residual with research
Compounding have with mixture invest small, lead time it is short and by attention both domestic and external, it is numerous and confused to increase development dynamics.
The synergistic combination of fluorine bacterium mite ester and tetramycin has not been reported, and the mechanism of action and effect of fluorine bacterium mite ester and tetramycin are special
Point is different.
Invention content
The present invention is intended to provide a kind of synergetic pesticide composition of fluorine-containing bacterium mite ester and tetramycin, is convenient for crop disease resistance
Management and reduction Pesticide use amount.
The invention is realized by the following technical scheme：
The composition pesticide of fluorine-containing the bacterium mite ester and tetramycin, active constituent be fluorine bacterium mite ester and tetramycin, preferably
Fluorine bacterium mite ester and tetramycin mass fraction ratio be 3:1~1:12.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:1~1:9.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:3~1:6.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:3.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:4.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:5.
The mass fraction ratio of further preferred fluorine bacterium mite ester and tetramycin is 1:6.
It is found by experiment that, fluorine bacterium mite ester is used in mixed way with tetramycin to pythium (Pythium), Phytophthora
(Phytophthora), Peronospora (Peronospora), Pseudoperonospora (Pseudoperonospora), white Phytophthora
(Peronophythora), refer to Phytophthora (Sclerophthora), white rust category (Albugo), Sclerospora
(Sclerospora), Plasmopara (Plasmopara), Bremia (Bremia), Erysiphales (Erysiphales) cause of disease
Object has synergistic effect.
The present invention has the advantages that：
1, the composition pesticide of fluorine containing active constituent bacterium mite ester and tetramycin provided by the invention, fluorine bacterium mite ester and tetramycin
There is synergistic effect to the toxicity of target pathogen within the scope of certain proportion, such as monofilament powdery mildew (Sphaerotheca
