Quintec Fungicide
for Powdery Mildew
Quintec® fungicide, a unique product for control of powdery
mildew, offers benefits you’ve never experienced. If you’re
in the business of producing high-quality crops, Quintec will
be an important part of your powdery mildew management
program.
Quintec can be used on melons, strawberries, leafy
vegetables and peppers.
Superior Fruit, Foliage Protection
Re-adsorption
Desorption
University field trials show that Quintec provides superior performance
under high and low pressure situations. It controls powdery mildew for up
to 14 days, depending on rate. Commercial use since 2007 has shown
excellent powdery mildew control and has validated the university trial work.
Quintec has the unique ability to redistribute across leaf and fruit/
vegetable tissues after application, forming a protective barrier as it moves.
That redistribution process is not a substitute for proper coverage, but the
movement helps Quintec reach areas that are out of the direct line of spray.
Totally Unique Class of Chemistry
Quintec is the only member of the quinoline class of chemistry
(FRAC Group 13). Its active ingredient, quinoxyfen, provides a mode
of action unlike any other fungicide used in vegetables – making it
ideal for resistance management programs. Quintec is an excellent
rotation partner with other fungicide classes, such as sterol inhibitors
(e.g. Rally® fungicide), strobilurins and sulfur.
Excellent Crop Safety
Commercial use in all crops since 2007 has shown a high level
of crop safety. Quintec has been included in university trials since
1999 and there have been no issues with crop safety when applied
according to the label.
Worker & Environmental Considerations
Quintec was reviewed and registered under the U.S. EPA’s Reduced
Risk Pesticide Program. The product label carries the signal word,
“Caution,” the lowest human hazard signal word available.
Trial Results
Since 1999, Quintec has been included in dozens of university field trials in vegetable/fruit crops.
Those trials were conducted by university cooperators, independent researchers and Dow AgroSciences.
In those trials, Quintec was a consistent, top–performing product.
University Trials
n The 2009 Yuma Ag Center melon trial included 39 different fungicide treatments. The top
treatment, Quintec at 5 oz/A, zeroed-out powdery mildew on upper leaf surfaces.
n In the 2008 Yuma Ag Center melon trial, Quintec was (numerically) the top treatment on lower
leaf surface ratings.
n In the 2007 Yuma Ag Center melon trial, three programs that included Quintec zeroed-out
powdery mildew on upper and lower surfaces.

n A pumpkin field trial in Solano County in 2009 by UC Davis, Dept. of Plant Pathology evaluated
20 different fungicide programs. Researchers found that “Quintec applications at 4 oz/A gave
the best results with 0% upper leaf surface incidence and no observable colonies in the central
lobe of leaves.”
A similar trial was conducted in 2008 with eleven treatments. Researchers found that “maximum
disease reduction on the upper surface of leaves was achieved with Rally alternated with
Quintec.” Eleven fungicide treatments were evaluated.

n In 2002, a Santa Maria strawberry trial conducted by Dr. Doug Gubler showed Quintec as
(numerically) the top treatment based on percent disease severity on leaves. That trial included
three strobilurins and two sterol inhibitors.
n Quintec was the top treatment – based on percent disease incidence on fruit – in a 2004
university trial in Santa Maria strawberries. The trial was conducted by Dr. Doug Gubler and
included five other fungicide treatments.
n A 2006 UC Extension-Imperial trial in lettuce showed Quintec as statistically equal to the top
treatment in the trial. Thirteen different treatments were in that trial.

Rotate with Rally Fungicide
®
Rally® fungicide is labeled for powdery mildew in cucurbits, strawberries, leafy vegetables,
peppers and many other vegetable crops. Its locally-systemic activity provides protective, curative
and eradicant activity, making it especially valuable when crops are growing fast. Studies have
shown that Rally has the innate ability to move in the direction of new growth, meaning emerging
and expanding leaves are protected. As a member of the sterol inhibitor class of chemistry
(FRAC Group 3), Rally is an excellent rotation partner with Quintec.
