Description
Technical field
Composition pesticide of the present invention is using Zhongshengmycin and fluorine bacterium azoles as active ingredient, suitable for preventing by white
Crop powdery mildew caused by powder Cordycepps (Erysiphales) pathogen.
Background technology
Zhongshengmycin, english common name：Zhongshengmycin is a kind of novel agricultural antibiotic, is by lilac grey
The antibiotic that the mutation of streptomycete Hainan generates belongs to N- glycoside alkali water-soluble substances.The processing dosage form of the bacterium is a kind of sterilization
The wider protective fungicide of spectrum, have tag, osmosis.Zhongshengmycin is to the bacterial disease and some fungi of crops
Venereal disease evil has very high activity, while have certain production-increasing function.It is safe to use, it can be used in Blooming Date of Apple Trees.
Zhongshengmycin is to crops pathogenic bacteria such as dish Bacteria erwinia, avenae subsp.citrull, rice leaf spot bacteria, apple wheel
Line disease germ, fusarium graminearum etc. are respectively provided with apparent antibacterial activity.It is generated by the peptide bond for inhibiting pathogenetic bacteria protein,
Eventually lead to bacterial death；It can inhibit the growth of mycelia to fungi, inhibit the sprouting of spore, play the work of prevention fungal disease
With；The generation of the precursor substance of protective plant protecting agent and lignin in plant can be stimulated, so as to improve the disease resistance of plant.
Fluorine bacterium azoles, english common name：Triflumizole, ergosterol demethylation inhibitors.Fluorine bacterium azoles are interior suction
Property fungicide, have excellent protection, therapeutic activity, holding effect activity and resistance of rainwater washing against activity；Suitable for wheat class, fruit tree, vegetable
The prevention of the powdery mildews such as dish, rust, peach brown rot
It is found by experiment that, Zhongshengmycin is used in mixed way with fluorine bacterium azoles to Fusicladium (Fusicladium), the black star spore of ring
Belonging to (Sphlocaea) and Erysiphaceae (Erysiphales) pathogen has synergistic function especially 20:1~1:
There is apparent synergistic effect to Erysiphaceae (Erysiphales) pathogen in 20 proportional regions.
By certain technological means, Zhongshengmycin can be using excipient as agriculturally common dosage form with fluorine bacterium azoles composition.
Invention content
The technical issues of present invention need to solve be：Overcome in the prior art dosage it is big, it is of high cost, to ecological environment endanger
Greatly, the shortcomings such as low to crop safety, provide a kind of efficient, safety, low toxicity and the lasting period is long, are conducive to comprehensive treatment crops
The composition pesticide containing Zhongshengmycin and fluorine bacterium azoles of white powder disease.
To solve the above problems, the technical solution adopted in the present invention is：A kind of agriculture containing Zhongshengmycin and fluorine bacterium azoles
Drug composition, including usual auxiliaries, Zhongshengmycin and fluorine bacterium azoles, the ratio of weight and number of Zhongshengmycin and fluorine bacterium azoles is 20:1-1:
20, the weight percent of Zhongshengmycin and fluorine bacterium azoles weight summation in composition pesticide is 5%-80%.
The composition pesticide of the present invention can be configured to suspending agent, oil suspends according to well known to a person skilled in the art methods
The application forms of the suitable agricultural use such as agent, water dispersible granules, wettable powder.
The composition pesticide also usual auxiliaries containing pesticidal preparations of the present invention, including solvent, emulsifier, wetting agent, steady
Determine one kind or several in agent, dispersant, thickener, antifoaming agent, antifreezing agent, disintegrant, binding agent, filler, filler, medium etc.
Kind mixing, is known substance, is common various auxiliary agents in pesticidal preparations, can be varied from, had no according to different situations
It is particularly limited to.
The composition pesticide of the present invention is particularly suitable for for preventing plant disease agriculturally by Erysiphaceae
(Erysiphales) crop powdery mildew caused by pathogen.
The composition pesticide of the present invention should occur early period in disease in application or disease early period of origination uses.
The composition pesticide of the present invention, is generally used by spray method, and can also use and agriculturally should as needed
Other use technology.
Composition pesticide provided by the invention has the advantages that：
1st, composition pesticide provided by the invention shows apparent synergistic effect, composition in certain ratio range
Control effect be significantly improved than single dose, reduce the dosage of pesticide, reduce drug cost, reduce pesticide pair
The adverse effect of ecological environment；
2nd, the combination of two kinds of fungicide of the invention, expands fungicidal spectrum；
3rd, two kinds of effective ingredient mechanism of action of composition pesticide provided by the invention are different, can overcome long-term list
One the shortcomings that resistance is easily generated using medicament, extend the service life of medicament, have to the comprehensive treatment of rice fungal disease
Significance.
