Description
Technical field
The present invention relates to plant protection art, particularly, relate to a kind of bactericide group, and the purposes of this bactericide in the fungus-caused crop pest of control.
Background technology
Fungi is most important phytopathy original monoid, in the real process of agricultural production, many important diseases such as anthracnose, downy mildew, white rot, spot defoliation, ring spot, early blight, late blight, shot hole, powdery mildew etc. are all by fungus-caused.At present, applying pesticides is the most effective means of control fungal diseases of plants.But the pesticide resistance of crop pest to agricultural chemicals strengthens gradually, and usually there is the problem that the mixing of dissimilar disease occurs in same crop, different diseases is often needed to adopt different bactericide to prevent and treat respectively, not only the control cycle is long, cost is high, also can cause serious environmental pollution, the more important thing is that control efficiency also cannot reach expection.
Therefore, in the urgent need to developing a kind of bactericide efficiently can tackled the mixing of dissimilar disease and occur.
Summary of the invention
The object of the invention is to overcome the defect that prior art cannot successfully manage dissimilar disease mixing generation, a kind of bactericide efficiently can tackled the mixing of dissimilar disease and occur is provided.
The present inventor passes through years of researches, be surprised to find that, it is composite by pyraclostrobin, Propineb and amino-oligosaccharide are carried out in certain proportion, the mixing can tackling number of different types disease efficiently occurs, find based on this, the invention provides a kind of bactericide, this bactericide contains active component, wherein, described active component comprises pyraclostrobin, Propineb and amino-oligosaccharide; Relative to the pyraclostrobin of 1 weight portion, the content of Propineb is 0.01-90 weight portion, and the content of amino-oligosaccharide is 0.005-45 weight portion.According to the present invention; pyraclostrobin; english common name: pyraclostrobin; chemical name: N-{2-[1-(4-chlorphenyl)-1H-pyrazole-3-yl oxygen methyl] phenyl } (N-methoxyl group) methyl carbamate; its mechanism of action is mitochondrial respiratory inhibitor, has protection, treatment, blade infiltration conduction.Its chemical constitution is
Propineb, english common name: propineb, chemical name: acrylic bisdithiocarbamic zinc.Its site of action is many, the main oxidation suppressing pyruvic acid in cause of disease thalline.Its chemical constitution is
Amino-oligosaccharide, english common name, oligochitosaccharins, chemical name: [(Isosorbide-5-Nitrae)-2-amino-2-deoxidation-β-D-Glucose]
n.Amino-oligosaccharide refers to the oligosaccharide that D-Glucosamine connects with β-1.4 glycosidic bond, and after obtaining shitosan by chitin degrading, degraded obtains again, or made by fermentable extraction.It is better water-soluble, is easily absorbed by organism, has special biologically active.Not only to fungi, bacterium, virus, there is extremely strong control and eradicant action, but also there is nutrition, adjustment, removing toxic substances, antibacterial effect.Control fruit tree, vegetables, underground rhizome, tobacco, the virus of traditional Chinese medicine and grain and cotton crop, bacterium, fungus-caused multiple diseases can be widely used in.Its chemical constitution is
Present invention also offers the purposes of bactericide as above in the fungus-caused crop pest of control, can be used for fruit tree, vegetables, melon, Cereal, flowers and lawn etc.
The present invention is composite by pyraclostrobin, Propineb and amino-oligosaccharide being carried out in certain proportion, the mixing can tackling number of different types disease efficiently occurs, with be used alone pyraclostrobin, Propineb is compared with amino-oligosaccharide, and compare with the two in amino-oligosaccharide is composite with using pyraclostrobin, Propineb, dissimilar disease mixing is had to the preventive and therapeutic effect of highly significant, dosage is lower simultaneously, can be cost-saving and reduce residual, alleviate the pollution to environment.
Other features and advantages of the present invention are described in detail in embodiment part subsequently.
