Ester.Its mechanism of action is the biosynthesis of the main phosphatide and fatty acid for inhibiting germ cell film component, mycelia is inhibited to grow,
The formation and sprouting of sporangium.Propamocarb category uptake and translocation fungicide can be absorbed simultaneously by root quickly when being used as soil treatment
It is conveyed upwards into entire plant；When acting on cauline leaf process, it can be absorbed and be distributed in blade by blade quickly, at 30 minutes
It is interior to play a protective role.
Disease caused by Oomycete pathogen is mainly downy mildew, and the zoospore travel speed of such germ is fast and quantity
Greatly, short incubation period, rapid onset after crop are infected, can occur repeatedly to infect again in a season of growth.In agricultural production, it applies
It is the most effective means of controlling plant diseases with chemical agent.But long-term continuous administration single variety fungicide or not scientific
Using pesticide, the drug resistance of disease is caused to get worse；Simultaneously as excessive result in environmental pollution and peasant using pesticide
The problems such as increase of drug cost, is unfavorable for the sustainable development of agricultural.Therefore, the compound medicine of efficient, low toxicity, low-residual is developed
Agent not only facilitates the drug resistance for delaying disease, but also can reduce dosage, save the cost, reduces the dirt to environment
Dye.
Inventor has made intensive studies the compounded formula screening of figured silk fabrics bacterium amine, finds figured silk fabrics bacterium amine and pyraclostrobin, alkene
Morpholide, iprodione, Propamocarb are compounded, and within the scope of certain compound proportion, are made to downy mildew with significant synergy
With.In actual use, there is preferable control efficiency to cucumber downy mildew, downy mildew of garpe.After further research,
Complete the present invention.

" the 7th part of farm-chemical indoor determination test rule fungicide: prevention and treatment cucumber downy mildew tests pot-culture method ".
5 various concentration gradients are arranged in single dose and each Mixed Pharmacy first, and (on the basis of preliminary experiment, bacteriostasis rate exists
It is set in the range of 5%~90% by geometric progression).Using pot-culture method, medical fluid is uniformly sprayed on blade face, to medical fluid natural wind
It is spare after dry.With spore suspension spray inoculation, then natural air drying moves to thermostatic chamber.Each 12h of daily continuous illumination/dark
Alternately, under conditions of temperature is 17~22 DEG C, 90% or more relative humidity, 7d~10d is cultivated.5 basins of every processing, 2 plants of every basin,
If blank control is repeated 4 times.When blank control disease leaf rate reaches 80% or more, incidence, every place are managed in classification investigation everywhere
Reason at least investigates 30 leaves.Grade scale are as follows:
0 grade: disease-free；
1 grade: lesion area accounts for 5% or less entire leaf area；
3 grades: lesion area accounts for the 6%~10% of entire leaf area；
5 grades: lesion area accounts for the 11%~25% of entire leaf area；
7 grades: lesion area accounts for the 26%~50% of entire leaf area；
9 grades: lesion area accounts for 50% or more of entire leaf area.
Disease index=[∑ (the disease numbers of sheets at different levels × opposite value of series)/(investigation total leaf number × 9)] × 100
Control efficiency (%)=(blank control disease index-chemicals treatment disease index)/blank control disease index ×
100
According to survey data, the disease index and control efficiency of each processing are calculated.Pass through preventive effect probability value and series of concentrations
Logarithm between linear regression analysis, find out the EC of each medicament50Value.

Pulvis) prevention and treatment cucumber downy mildew field trial, by with 150 grams/ha of 25% pyraclostrobin suspending agent of comparison medicament, 50%
250 grams/ha of dimethomorph wettable powder, 722 800 grams/ha of grams per liter propamocarb aquas, the different bacterium of 500 grams per liters
550 grams/ha of urea suspending agent, 50% figured silk fabrics bacterium aqueous amine dispersible granule effect be compared, demonstrate the medicament to cucumber downy mildew
Sick control efficiency and the safety to cucumber.
Trial crops are cucumber, and controlling object is cucumber downy mildew (Pseudoperonospora cubensis).Test
It is located at Yang Ling acrobatic skill town, experimental plot topography is flat, and soil is loam, middle fertility, pH value 6.9, during test in fertilizer and water management
Deng.See Table 5 for details for test medicine and dosage.Separately set blank control, 4 repetitions of every processing, every 30 square meter of cell, the random district's groups of cell
Arrangement.Using conventional spray-on process, leave dual sides are uniformly sprayed.
Investigation and statistical method: 10 days investigation state of an illness radixes after last time is administered, every cell take at 4 points at random, every tune
2 plants are looked into, the whole blades of every plant of investigation, every blade accounts for the percentage classification record of leaf area according to scab.Stage division:
0 grade: disease-free spot；
1 grade: lesion area accounts for 5% or less entire leaf area；
3 grades: lesion area accounts for the 6%~10% of entire leaf area；
5 grades: lesion area accounts for the 11%~25% of entire leaf area；
7 grades: lesion area accounts for the 26%~50% of entire leaf area；
9 grades: lesion area accounts for 50% or more of entire leaf area.
Disease index=[∑ (the disease numbers of sheets at different levels × opposite value of series)/(investigation total leaf number × 9)] × 100
Control efficiency (%)=(blank control disease index-chemicals treatment disease index)/blank control disease index ×
100
5 figured silk fabrics bacterium amine of table and pyraclostrobin, dimethomorph, iprodione, Propamocarb compounding prevention and treatment cucumber downy mildew test knot
Fruit
Field test results indicate that the above example of formulations treatment region reaches 80% or so to cucumber downy mildew,
Preventive effect is substantially better than comparison medicament treatment region, and preventive effect difference reaches extremely significant level.
Security survey to cucumber, cucumber growth safety, no phytotoxicity phenomenon occur for each test process after being administered 2 times.
To sum up, complex composition activity of the invention and bactericidal effect are not the active simple superposition of each effective component, with
Existing binary combination and single formulation are compared, and preventive effect is not only increased, and slow down disease drug resistance, reduce cost, improve life
Benefit is produced, and to Target crops safety.So the invention of this compound preparation has a very important significance society with popularization.
