A PREVENTATIVE APPROACH FOR
PROTECTING AGAINST HARMFUL NEMATODES
W
ith very few control
options on the market
for harmful nematodes,
many growers focus on preventive
measures to ensure they won't
have problems with root knot,
root lesion or other problematic
nematodes often present in soil
throughout the growing season.
Since nematodes can overwinter
underground in fragments
of vegetative crop roots, it is
important for growers to properly
prepare soil prior to spring
fumigation.
Preventing harmful nematodes
requires an integrated pest
management strategy, utilizing all
tools available, to manage current
nematode damaging populations.
To better understand the ideal
methodology for preparing soil
prior to fumigant application, we
talked with Dr. John Washington.
John is a plant pathologist with
an MS in nematology who works
with vegetative crops and orchards
around the world, with special
emphasis on soil fumigation and
soil health.
IPM strategy steps
for managing harmful
nematodes in vegetative
crops
To achieve quality results, here are
recommendations that vegetable
growers should consider when
protecting their crops from these
damaging organisms:
1. Test the soil. Take samples
and work with a quality lab
or local university to find out
what your field's nematode
pressure looks like.
2. Soil rip. After harvesting
crops at the end of the
season, use a field shank
to break up soil at least 10 "
deep.
3. Remove previous plant
material. Remove any root
debris, eliminating the places
where harmful nematodes
can survive through the
winter.
4. Thoroughly till soil. Ensure
that all clods are broken up

much colder winters. This
allows for great suppression
of damaging nematodes,
and does not delay spring
planting dates.
Fumigation timing and soil
health
For those in the northern U.S. with
a hard freeze or late spring thaw,
preparing the soil and treating with
fumigant in the fall offers the same
advantages as a spring application
in warmer climates. However, if a
Chloropicrin broadcast is planned
for pre-plant or if the field will
receive fumigant for the first time,
spring is an ideal time to apply.

to prepare soil for not only a
good seal for fumigation, but
also to promote young root
establishment.
5. Fumigate. Use a pre-plant
fumigant such as Telone™ II
in a broadcast application,
which can help prevent
future hotspots. Telone™
II can also be applied in a
dual application with other
fumigants, depending on the
historical weed or disease
pressure in the field be
treated. Dual applications
can save labor costs and
precious time. A Telone &
Chloropicrin combination
is also a winner for growers
concerned about harmful
nematodes and bacterial
issues - and an " ideal
combination " according to
Washington.
6. Ongoing IPM strategy.
Application of Telone™ II
should be done prior to
planting each season, based
on the concentration of
nematodes identified in each
field (or in the fall in areas
with colder temperatures).
Due to nematodes biology
and behavior, nematodes
are more active in the
upper several feet of soil
within warmer soils, which
supports a fall fumigant
application, especially with
northern states which have
About TeloneTM II
Telone™ II soil fumigant is a
preplant soil fumigant for control
of all major species of nematodes,
including root-knot, lesion, stubbyroot,
dagger, ring and cyst, plus
certain insect pests. Telone II is
injected into the soil as a liquid
and immediately converts to a
gas, ultimately creating a zone
of protection around developing
roots. As a fumigant, Telone moves
throughout the soil profile without
requiring water or incorporation
for movement. Learn more about
Telone at www.teleosag.com.
