Abstract
The present invention relates to the microemulsion of a kind of Tebuconazole and garlicin, in described microemulsion, effective ingredient is Tebuconazole and garlicin；Auxiliary agent is fatty alcohol-polyoxyethylene ether, N octylpyrrolidone, propylene glycol, silicone oil.The present composition has extraordinary prevention effect to powdery mildew of cucumber, the present invention utilizes the bactericidal activity of Tebuconazole and garlicin to have preferable synergism, effectively enhance the effect of the prevention to powdery mildew of cucumber and treatment, morbidity early stage dispenser instant effect, and the lasting period is long, on non-Target crops without impact.
Description
Technical field
The present invention relates to the microemulsion of a kind of Tebuconazole and garlicin, be specifically related to the microemulsion of Tebuconazole and garlicin for preventing and treating powdery mildew of cucumber, belong to technical field of pesticide.
Background technology
Tebuconazole belongs to triazole bactericidal agent, is sterol demethylation inhibitor.Tebuconazole be a kind of efficiently, wide spectrum, interior absorption triazole bactericidal agent, there is protection, treat, root out three zones, fungicidal spectrum extensively, the lasting period long.The features such as these product are used for preventing and treating sclerotinia rot of colza, and not only preventive effect is good, and have resistant to lodging, and production-increasing function is obvious.It is the efficient germicide sprayed for seed treatment or the face of Important Economic crop, can effectively prevent and treat the multiple rust of cereal crop, powdery mildew, net blotch, root rot, head blight etc..
Garlicin (Allicin) is a kind of organosulfur compound extracted from the bulb (Bulbus Allii head) of Liliaceae allium Bulbus Allii (Allium Sativum), exists in Bulbus Allii Cepae and other alliums.Formal name used at school GIUCOSinoate.Pale yellow oily liquid body.Boiling point 80-85 DEG C (0.2kPa), relative density 1.112(20/4 DEG C), index of refraction 1.561.It is dissolved in ethanol, chloroform or ether.Dissolubility 2.5% (quality) (10 DEG C) in water, its pH value of water solution is 6.5, has grease precipitate to be formed during standing.Can dissolve each other with ethanol, ether and benzene.Unstable to thermokalite, stable to acid.By in the bulb being present in liliaceous plant Bulbus Allii, the garlic aminoacid existed under big allinase effect, convert generation.Exist in the bulb of Herba Alii fistulosi.Having strong big garlic odour, taste is peppery.
The industrial crops cultivated areas the such as at present difficulty of prevention and cure of phytopathogen is increasing, on the one hand, along with the change of pattern of farming, melon fruits and vegetables progressively expand, and disease occurrence degree, occur quantity all to increase, and in preventing and treating, difficulty strengthens；On the other hand, the resistance of pathogen rises under lasting medicament selection pressure year by year, and the prevention effect of single dose is more and more weak, and control of plant disease faces significant challenge.
Summary of the invention
For the problems referred to above, the invention provides the microemulsion of a kind of Tebuconazole and garlicin, the present invention is effective, holding effect is long, to non-Target crops safety.
Technical scheme is as follows:
A kind of Tebuconazole and the microemulsion of garlicin, effective ingredient is Tebuconazole and garlicin；Auxiliary agent is fatty alcohol-polyoxyethylene ether, NOP, propylene glycol, silicone oil.
Further, each raw material components percentage in the present composition:
Tebuconazole 1%-50%, garlicin 0.1%-1%, fatty alcohol-polyoxyethylene ether 5%-10%, NOP 5%-10%, propylene glycol 1%-5%, silicone oil 0.1%-0.5%, deionized water supply 100%.
Further, each raw material components percentage in the present composition:
Tebuconazole 10%-40%, garlicin 0.1%-0.5%, fatty alcohol-polyoxyethylene ether 6%-9%, NOP 6%-10%, propylene glycol 2%-4%, silicone oil 0.1%-0.4%, deionized water supply 100%.
Further, each raw material components percentage in the present composition:
Tebuconazole 30%, garlicin 0.3%, fatty alcohol-polyoxyethylene ether 8%, NOP 9%, propylene glycol 3%, silicone oil 0.2%, deionized water supply 100%.
Compositions of the present invention is used for preventing and treating powdery mildew of cucumber；Insecticide-applying way is spraying；Dispenser period is their early stage；Annual spraying times is 1 or 2 time；Effective ingredient dosage of the present invention is 8 grams/ha-15 grams/ha, it is preferred that dosage is 9.3 grams/ha.
The present composition has extraordinary prevention effect to powdery mildew of cucumber, the present invention utilizes the bactericidal activity of Tebuconazole and garlicin to have preferable synergism, effectively enhance the effect of the prevention to powdery mildew of cucumber and treatment, morbidity early stage dispenser instant effect, and the lasting period is long, on non-Target crops without impact.

Test example 1 present invention prevention effect to powdery mildew of cucumber
1, test method
Test site, in Liaocheng of Shandong Province, is Fructus Cucumidis sativi for studying thing, and test sets every mu of comparison totally 10 process, often processes and is repeated 4 times, and random district group arranges, and plot area is 40 square metres.
2, control time and number of times
Before dispenser, after the 1st medicine after 7 days and the 2nd dispenser 7 days, 14 days, every community used diagonal 5 sampling, every some investigation 20 strains, investigates occurring degree by leaf classification, and calculating disease refers to and prevention effect.
Grade scale is as follows:
0 grade: anosis；
1 grade: lesion area accounts for less than the 5% of one-piece blade area；
3 grades: lesion area accounts for the 6%-15% of one-piece blade area；
5 grades: lesion area accounts for the 16%-25% of one-piece blade area；
7 grades: lesion area accounts for the 26%-50% of one-piece blade area；
9 grades: lesion area accounts for more than the 50% of one-piece blade area.
3, drug effect computational methods
Sick leaf rate (%)=sick number of sheets/investigate the total number of sheets × 100；
Disease index=∑ (the sick number of sheets × relative level numerical value at different levels)/(investigating the total number of sheets × 9) × 100
Prevention effect (%)=[disease index after disease index × treatment region medicine before 1-(blank district medicine)/(disease index before disease index × treatment region medicine after blank district medicine)] × 100.
4, poisoning investigation method
After dispenser, whether continuous 14d range estimation medicament has poisoning to crop.
