Growers must be proactive with their
disease-control plan every season if
they want to prevent white mold from
damaging their crops.
White mold can remain in the soil
over the winter, living in dark-colored
resting structures call sclerotia.
" When temperature and moisture
are right, spores are released from
the sclerotia and will infect the plant
blossoms. Usually this coincides
with row closure and full bloom, "
said Tye Shauck, Technical Service
Representative at BASF. " Those
infected blooms fall into the canopy,
where they continue to spread the
white mold pathogen. "
Therefore, it's crucial that growers
make the first fungicide application at
the right time to prevent white mold
from becoming a larger issue later.
The market standard for
control
Shauck recommends growers look to
the market standards to protect crops
against white mold. Endura®
is a FRAC group 7 and one of those
market standards. Endura fungicide
works to stop the energy centers of
white mold cells from functioning
properly; as a result, the cells die.

" Once the plants are wilting, most of
the damage is already done. Even if
you kill the pathogen, you will have
lost a significant amount of yield.
You can start to see symptoms 10-14
days after infection takes place, "
said Shauck. " By applying Endura
fungicide preventatively, growers
fungicide
stand a better chance of weathering
the season without white mold
crippling their crop. "
The right fungicide at the
right time
Growers should apply Endura
fungicide during bloom, which is
typically around row closure, to
control white mold as well as early
blight. They can also choose to
tank-mix chemistries that control
other pathogens. However, Endura
fungicide should be applied in
rotation with other chemistries, and
no more than two FRAC group 7
chemistries should be applied back
to back.
The first application is the most
important because Endura fungicide
works to protect the plant by
preventing infections and has some
residual activity. By applying early
and following up on applications,
plants are optimally protected from
white mold. " Don't wait too long for
sequential fungicide applications;
otherwise you will have a gap in
which you will not have residual
protection, " said Shauck.
After that initial application,
subsequent applications should fall
every 7-14 days at regular intervals
to continue to protect the plant.
Crop rotation can also help reduce
the threat of white mold. White mold
can survive in soil for years, and by
rotating crops, growers can further
reduce the risk that white mold will
become a problem.
