GREAT LAKES EXPO NEWS
Focusing on tart cherries, peaches at EXPO
GREAT LAKES
FRUIT, VEGETABLE & FARM MARKET
Tart cherry and peach growers each
have a dedicated session on Wednesday
morning of the Great Lakes Fruit,
Vegetable & Farm Market EXPO to
be held Dec. 10-12 in Grand Rapids,
Michigan. Researchers will present
information about maximizing efficiency
in chemistry applications for peaches and
susceptibility of tart cherries to spotted
wing drosophila, among other details.
Norm Lalancette is an Extension
specialist in tree fruit pathology located
at the Rutgers Agricultural Research
and Extension Center in Bridgeton,
New Jersey, with ongoing peach studies
in Georgia. The goals of his studies are
to figure out what the most efficient
and effective uses of pesticides and
fungicides are with peaches. He works
to prevent fungicide resistance and to
eliminate peach scab and brown rot.
In order to discover the best chemical
rotation to prevent common peach
diseases and pests, Lalancette repeats
the studies for several years to ensure
weather patterns such as heavy rains
won't impact the findings.
" What rate is
the lowest rate
we can use for
effectiveness?
What is the timing
for the biggest
benefit at harvest?
We're trying to
narrow it down
little by little to be
more efficient, "
Lalancette said.
His session will focus on timing
most efficient for peaches in Georgia. He
will present several years' worth of data
to attendees so they can feel confident in
making the changes he suggests.
In addition to key information about
NORM
LALANCETTE
and materials for best coverage on
peaches before, during and after
harvest, regardless of rain volume that
season. Lalancette suggests that all
peach growers should attend and that
regardless of the region, growers will be
able to take away valuable information
about pesticide and fungicide use, plus
learn to have more consistent brown rot
control each year.
Besides resistance management and
timing sprays for the best results at
harvest, Lalancette will discuss the correct
materials at the right rate to teach growers
what years of testing have shown are the
disease management in peaches that
growers need to hear, tart cherries
will take the focus of a session led by
Christelle Guedot, fruit crop entomologist
and assistant professor and Extension
specialist at the University of Wisconsin,
Madison's Department of Entomology.
Guedot studies several varieties of tart
cherries and how and when spotted wing
drosophila lay eggs and hatch into larvae
at each growth stage.
Her
presentation
will include
research in tart
cherries such as
Montmorency,
Tibetan and
Carmine Jewel,
plus others.
Each cherry
was collected at
specific growth
stages, from green,
pink and red. The flies were allowed to
interact with the cherries, and she noted
CHRISTELLE
GUEDOT
when they laid eggs, when they were
hatching and overall growth stages. " The
timing when they are ripening is the
most important, " Guedot said.
Tart cherry growers will learn about
when each cultivar is susceptible to
spotted wing fly infestations. This
information is especially important since
spotted wing flies were at record highs
during the 2019 season in Michigan.
" Since we have all the samples, we
came up with models to show why flies
might be most active and what is the
coordinating trap catch, " Guedot said.
Lalancette encourages growers to
attend EXPO. " There will be lots of
interaction between growers that aren't
growing the same things. You might
learn things you don't normally learn on
your own, " Lalancette said. Plus, EXPO
is where growers can stay abreast of the
latest research.
Guedot is looking forward to having
one-on-one conversations with growers
between sessions or at meals. " It's one
of the best venues in the Midwest. The
research is focused on what the Midwest
is facing, " Guedot said.
