Odyssey DLX (cont’d)
Application Tips
Water soluble bags will dissolve better when kept intact; do not split bags. If agitation is stopped for more that 5
minutes, re-suspend spray solution by full agitation prior to commencing spraying again. Do not spray Odyssey DLX
if temperatures of +5
o
C or lower are forecasted within 3 days of application. Temperatures near freezing (below
5
ºC) will prevent optimum herbicide performance, as weeds are not actively growing. Apply when weeds are small
and actively growing, soil moisture is good and the crop is small enough to permit through spray coverage. During
periods of stress, plants are not actively growing and reduced weed control or crop injury may result. When grasses
are stressed due to drought, flooding, hot or prolonged cool temperatures (15°C or less) or coverage is inadequate,
unsatisfactory control may result. Initial transient crop yellowing may be observed after application, but this is
outgrown and should not affect yield. Use 50 mesh or coarser filter screens.
How it Works
Absorbed by foliage and roots. Disrupts plant metabolism causing growth to stop. Works best under good growing
conditions. Residual activity of small seeded, shallow germinating flushing weeds (not wild oats) expected until crop
flowering. Moist conditions result in better residual control.
Expected Results
Odyssey causes susceptible weeds to stop growing within 24 - 48 hours. Yellow striping and purplish or reddish
discolouration of the leaves may occur. Leaves begin to die in 3 - 10 days starting with the youngest and moving to
the older leaves. Death of the plant may occur in 1 - 3 weeks. Equinox is a systemic herbicide that causes growth
to cease within 48 hours. Young leaves will turn yellow within 5 - 10 days; some grasses will then turn reddish.
Necrotic spots will form on grass leaves.
Restrictions
Rainfall
:
Do not apply if rain is expected within 3 hours.
Grazing
:
Do not graze treated peas 60 days after application.
Pre-harvest Interval
:
After 60 days, field peas, CLEARFIELD canola and CLEARFIELD lentils can be harvested.
Re-cropping
:
Barley, CLEARFIELD canola, canary seed, chickpeas, durum wheat, field corn, field peas, lentils
(
incl. CLEARFIELD lentils), oats, and spring wheat can be grown safely the year following an application. Flax,
non-CLEARFIELD canola and sunflowers can be grown in the second year after an Odyssey application (e.g. if you
used Odyssey in 2010, you can grow non-CLEARFIELD canola in 2012). Research studies have shown that flax, non
CLEARFIELD canola and non CLEARFIELD sunflower may be safely planted two (2) years following ODYSSEY
WDG Herbicide application in all regions of Western Canada except the Peace River Region of Alberta and British
Columbia. In the Peace River Region, wait a minimum of 3 years and perform a field bio-assay the year prior to
planting canola. For other crops, call BASF at 1-877-371-2273. Conduct a field bioassay the year before growing any
crops other than those listed above. In case of crop failure, replant only to CLEARFIELD canola or field peas.
Environmental Precautions
Odyssey is highly toxic to non-target plants. A buffer zone of 14 metres is required between the downwind point of
direct application and the closest edge of sensitive terrestrial or aquatic habitats. DO NOT contaminate water supplies
or aquatic habitats by application or cleaning of equipment or disposal of wastes.
Runoff
:
Avoid runoff from treated areas into aquatic habitats.
Toxicity
Low acute toxicity. Acute oral LD
50
(
rats) = 5,000 mg/kg. Non-toxic to fish, birds and bees.
Storage
Store at temperatures above 5°C. Keep unused water soluble bags in resealed, original container. Keep packages dry
at all times.
