Description
Technical field
The invention belongs to pesticide field, and in particular to a kind of bactericidal composition containing benzothiostrobin and cyflufenamid.
Background technology
Benzothiostrobin is by a kind of strobilurin fungicide of Central China Normal University's research and development, its effect side
Formula with the Qo sites of cytochrome b (cytb) in mitochondrial complex III mainly by being combined to prevent the electricity in mitochondria
Son transmits, and suppresses the respiration of pathogen.The medicament especially shows excellent in terms of most important crop disease powdery mildew is prevented and treated
It is different, and to crop and Environmental security.
Cyflufenamid has excellent effect and characteristic to the powdery mildew of various vegetables and wheat class, peach grey scab bacterium, while right
Benzimidazole, imidazoles, methoxy acrylate class resistance bacterium and sensitive bacteria have same isoreactivity.The mechanism of action is by suppressing white
The formation and growth of haustorium mitogenetic on mycelia in the powder germ history of life (namely pathogenic process), the growth and attachment of secondary hyphae
The formation of device.Cyflufenamid is extremely low to the toxicity of people and animals, and in the absence of on follow-on influence, teratogenesis, mutagenicity test is all
It is negative, also not to eye, the stimulation of skin and allergy in production.
It facts have proved that resistance problem easily occurs in the long-term use of chemical pesticide single dose, cause dosage to continue to increase, risk
Increase, is unfavorable for Environment Ecological Safe.Seek scientific and rational agriculture chemical compounding, be to solve the preferable method of this problem.Will not
Pesticide active ingredient with structure type is compounded, and is current to solve the problems such as cost and resistance in agricultural chemicals single dose application process
A kind of effective means.After the pesticide active ingredient mixing of different types of structure, three kinds of type of action are typically exhibited, that is, are added
Effect, synergistic effect and antagonism, but be specially which kind of effect, it is unpredictable, only just it can know that by lot of experiments.It is multiple
It is formulated well with synergy, actual prevention effect can be improved, is reduced the usage amount of agricultural chemicals, contribute to the generation of delaying drug resistance, be
The important means of scientific prevention and cure pest and disease damage.The relevant report at home and abroad also compounded at present without benzothiostrobin and cyflufenamid.
The content of the invention
To solve technical problem of the prior art, present invention aims at provide a kind of new and effective pesticide combination
Thing, be mainly used in wheat class, strawberry, grape, apple, cucumber etc. preventing and treating powdery mildew and banded sclerotial blight, droop, leaf spot, gray mold,
Sclerotiniose and rust.
Technical scheme provided by the invention is as follows:
A kind of composition pesticide containing benzothiostrobin and cyflufenamid, the active ingredient of the composition pesticide is benzene thiophene bacterium
Ester and cyflufenamid, remaining is auxiliary element, and wherein the mass ratio of active ingredient benzothiostrobin and cyflufenamid is 1-50: 50-
1。
The mass ratio of active ingredient benzothiostrobin and cyflufenamid is 1-25: 25- in composition pesticide of the present invention
1。
Benzothiostrobin accounts for whole preparation with the gross weight of cyflufenamid in the formulation in composition pesticide of the present invention
The 1%~80% of quality.
Benzothiostrobin accounts for whole preparation with the gross weight of cyflufenamid in the formulation in composition pesticide of the present invention
The 10%~50% of quality.
The formulation of composition pesticide of the present invention is missible oil, suspending agent, wettable powder, water dispersible granules, aqueous emulsion, micro emulsion
Agent, microcapsule formulations, granule, aqua.
Composition pesticide of the present invention is used for the purposes for preventing and treating crop disease.It is preferred for the preventing and treating of powdery mildew.
Compared with prior art, the present invention has the advantages that：
1st, synergistic effect is obvious：Composition shows good synergistic effect in certain ratio range, improves composition
Protection effect.
2nd, preventing and treating spectrum is expanded：Composition can be on plant multiple diseases.
3rd, use cost is reduced：Preventive effect, preventing and treating spectrum increase are improved because compounding has, reduces access times, reducing makes
Use cost；
4th, the resistance to the action of a drug is delayed：The composition compounding of two kinds of different mechanism of action, pathogen are not likely to produce the resistance to the action of a drug, delay cause of disease
Thing is to the drug-fast generation of single dose.
