Description
Technical field
The present invention relates to technical field of pesticide, the specifically bacterium of benzene containing nitre ester (Meptyldinocap) and triazole bactericidal agent
In epoxiconazole (Epoxiconazole), Cyproconazole (Cyproconazole) and Fluquinconazole (Fluquinconazole) optionally
A kind of composition pesticide compounded as binary active ingredient.
Background technology
Use with the single, frequent of chemical pesticide triazole type medicament in recent years and largely, make powdery mildew to medicament sheet
The resistance of body is growing day by day.Meanwhile, the frequent of chemical pesticide is largely used, and serious destruction is caused to the ecosystem.Nitre benzene bacterium
Ester has special efficacy as a kind of uncoupler of brand-new oxidative phosphorylation to the powdery mildew that all triazole type medicaments play resistance.Will
The advantages of combination of nitre benzene bacterium ester and triazole type medicament has energy delaying drug resistance, Synergistic.Meanwhile, nitre benzene bacterium ester and triazole type
The composition of medicament can reduce medicament usage amount and number of times, reduce residues of pesticides, and ecological environment is brought to improving chemical pesticide
Destruction plays a very good protection.It can be seen that, prevent and treat the composition pesticide of plant powdery mildew all has to agricultural production and life
Great meaning.
It is used as the nitre benzene bacterium ester of active component (I), Chinese：2,4- dinitro -6- (1- methyl) phenylcrotonic acid ester,
It is a kind of uncoupler of brand-new oxidative phosphorylation, tool prevention, treatment and shoveling function simultaneously have limited Penetration Signature concurrently.It
Containing individual isomer, with low toxicity, the features such as dosage low (2~10g/hm2).It is registered for preventing and treating in many countries
Important crops are (for example：Grape, vegetables) powdery mildew；It is environmentally friendly, to natural enemies security.The mechanism of action of nitre benzene bacterium ester with
Other prevent and treat the bactericide of powdery mildew compared to being unique, can delay the drug-fast generation of germ.
It is used as the epoxiconazole of one of active component (II), chemical name：(2RS, 3RS) -1- [3- (2- chlorphenyls) -2,3-
Epoxy -2- (4- fluorophenyls) propyl group] -1H-1,2,4- triazoles belong to one of novel triazole bactericidal agent.Its active component leads to
The synthesis for suppressing germ ergosterol is crossed, the formation of germ cell membrane is hindered, and to fungal enzyme (14-dencthylase)
Activity also has very high inhibition effect, compared with the bactericide being currently known, can more effectively suppress the generation of disease fungus.Simultaneously
Epoxiconazole can also improve the chitinase activity of crop, cause the contraction of fungi haustorium, suppress germ intrusion, improve crop pair
The immunocompetence of disease.Epoxiconazole energy effectively preventing Cereal damping-off, powdery mildew, eyeprint disease, banana, green onion garlic, celery, dish
Leaf spot, powdery mildew, the anthracnose in rust, and grape, white rot etc. on the crop such as beans, melon, asparagus, peanut, beet
Disease.
It is used as two Cyproconazole of active component (II), chemical name：[- 4- is just by 2- (2,4 dichloro benzene base) by (±) -1-
Propyl group-DOX -2- ylmethyls] -1H-1,2,4- triazoles belong to one of triazole type wide spectrum low-toxicity bactericide.It is made
It is to influence the biosynthesis of sterol with mechanism, is destroyed the cell membrane function of pathogen, ultimately result in cell death, so that
Sterilization, diseases prevention and the effect cured the disease are played, with protection and therapeutic action；Propiconazole has absorbability simultaneously, can be by plant
Root, stem, leaf portion absorb, and soon can be conducted upwards in plant strain body, effectively preventing sac fungus, basidiomycetes and can partly know
Microbial plant disease, particularly to uncinula necator, false smut, take-all, powdery mildew, rust, root rot, banana
Leaf spot has outstanding prevention effect.
It is used as three Fluquinconazole of active component (II), chemical name：(2RS, 3RS) -1- [3- (2- chlorphenyls) -2,3-
Epoxy -2- (4- fluorophenyls) propyl group] -1H-1,2,4- triazoles belong to one of novel triazole bactericidal agent.Its active component leads to
The synthesis for suppressing germ ergosterol is crossed, the formation of germ cell membrane is hindered, and to fungal enzyme (14-dencthylase)
Activity also has very high inhibition effect, compared with the bactericide being currently known, can more effectively suppress the generation of disease fungus.Simultaneously
Epoxiconazole can also improve the chitinase activity of crop, cause the contraction of fungi haustorium, suppress germ intrusion, improve crop pair
The immunocompetence of disease.Epoxiconazole energy effectively preventing Cereal damping-off, powdery mildew, eyeprint disease, banana, green onion garlic, celery, dish
Leaf spot, powdery mildew, the anthracnose in rust, and grape, white rot etc. on the crop such as beans, melon, asparagus, peanut, beet
Disease.
At present, active component (I) nitre benzene bacterium ester is a kind of new type bactericide of LG-DOW Yi Nong Co., Ltds exploitation.Nitre
Benzene bacterium ester shows there is special efficacy to the fungal disease based on powdery mildew through field control effectiveness test result.Have 36% on the market at present
Missible oil and 18% suspending agent (with Fluoxastrobin) have registration；The epoxiconazole, Cyproconazole and Fluquinconazole of next active component (II)
There are missible oil, microemulsion, aqueous emulsion, suspension seed-coating agent, suspending agent, wettable powder and water dispersible granules etc. single common on the market
Agent and a variety of formulations of built agent.But nitre benzene bacterium ester and the composition pesticide that epoxiconazole, Cyproconazole and Fluquinconazole are compounded are domestic and international
Also there is not been reported.
The content of the invention
It is an object of the invention to provide in the bacterium ester of benzene containing nitre and triazole bactericidal agent epoxiconazole, Cyproconazole and Flusilazole
One of compounding for binary active ingredient composition pesticide.
The technical scheme adopted by the invention to solve the technical problem is that：
