Vibe) with 3.6 lbs. a.i. per gallon that use the same rate. REI:
12-hour to 18-day. PHI: 7-day. FRAC 03.
Nematodes
Northern root knot nematode (NRKN) has a wide host range,
including most broadleaf crops and weeds, but seem to have a
disproportionate effect on carrots resulting in large yield
losses if uncontrolled. Carrot cyst nematodes (CCN) are also
found throughout the region and only feed on carrots. Sugar
Beet Cyst Nematode (SBCN) will infect beets, radishes,
rutabagas, and turnips.
Non-Pesticide
Beet, Carrot, Horseradish, Radish, Rutabaga, Turnip |
Collect soil samples for nematodes in the fall and avoid fields
with high numbers. Prompt destruction of the finished crop
with tillage to rapidly breakdown tissue and displace
nematodes is an important method to prevent nematode buildup.
Anaerobic soil disinfestation (ASD) is an effective
sterilization method for greenhouse and high tunnel soils that
contain nematodes. For NRKN: rotate to a non-broadleaf
crop, such as grass grains or sweet corn for >3 years. For
SBCN: a late-summer, or early-fall cover crop of 'Defender',
'Concorde', or 'Control' radishes are effective trap crops for
SBCN.

K-PAM HL (5.8L) (metam potassium) Beet, Carrot,
Celeriac, Horseradish, Parsnip, Radish, Rutabaga, Turnip |
30-62 gals. per acre. Use high rates on muck, and lower rates
on sands. In the fall, when soil at 6 inches is above 50 F and
moist, place K-PAM HL or Sectagon K54 about 8 inches
beneath the surface through shank-injectors, or broadcast
sprayers directly in front of tillage tools to bury it. Seal with
soil packing or irrigation. Or, in the spring, it can be applied
through drip irrigation under unperforated plastic beds.
Before planting, allow product to dissipate for 1 week for
every 10 gals. per acre plus 1 more week. REI: 5-day. IRAC
08F, FRAC M03, HRAC NC. RUP.
Telone C-17 (L) (1,3-dichloropropene, chloropicrin) Beet,
Carrot, Celeriac, Horseradish, Parsnip, Radish, Rutabaga,
Turnip | Muck soils: Use C-17 formulation at 27.4-30 gals.
per acre, and C-35 formulation at 33-36 gals. per acre.
Mineral soils: Use C-17 formulation at 10.8-17.1 gals. per
acre, and C-35 formulation at 13-20.5 gals per acre. In the
fall, when soil at 6 inches is above 50 F and moist, place
Telone C-17 or C-35 about 8 inches beneath the surface
through shank-injectors, or broadcast sprayers directly in
front of tillage tools to bury it. Seal with soil packing,
irrigation, or plastic. Or, in the spring, InLine may be applied
through drip irrigation under unperforated plastic beds at 1320.5
gals. per acre on mineral soils only. Before planting,
allow product to dissipate for 1 week for every 10 gals. per
acre plus 1 more week. REI: 3-5-day. IRAC UN, FRAC NC,
IRAC 08B. RUP.
Telone II (9.85L) (1,3-dichloropropene) Beet, Carrot,
Celeriac, Horseradish, Parsnip, Radish, Rutabaga, Turnip |
Muck soils: Use at 25 gals. per acre. Mineral soils: Use at 912
gals. per acre. In the spring or fall, when soil at 6 inches is
above 50 F and moist, place Telone II about 8 inches beneath
the surface through shank-injectors, or broadcast sprayers
directly in front of tillage tools to bury it. Seal with soil
packing or irrigation. Or, in the spring, Telone EC may be
applied through drip irrigation under unperforated plastic
beds at 9-18 gals. per acre on mineral soils only. Before
planting, allow product to dissipate for 1 week for every 10
gals. per acre plus 1 more week. REI: 5-day. IRAC UN,
FRAC NC. RUP.
VAPAM HL (4.25L) (metam sodium) Beet, Carrot,
Celeriac, Horseradish, Parsnip, Radish, Rutabaga, Turnip |
37.5-75 gals. per acre. Use high rates on muck, and lower
rates on sands. In the fall, when soil at 6 inches is above 50 F
and moist, place VAPAM HL or Sectagon K42 about 8
inches beneath the surface through shank-injectors, or
broadcast sprayers directly in front of tillage tools to bury it.
Seal with soil packing or irrigation. Or, in the spring, it can
be applied through drip irrigation under unperforated plastic
beds. Before planting, allow product to dissipate for 1 week
for every 10 gals. per acre plus 1 more week. REI: 5-day.
