Application Tips
Water soluble bags will dissolve better when kept intact; do not split bags. If agitation is stopped for more than 5
minutes, re-suspend spray solution by full agitation prior to commencing spraying again. Do not spray Odyssey if
temperatures of +5
o
C or lower are forecasted within 3 days of application. Temperatures near freezing (below 5ºC)
will prevent optimum herbicide performance, as weeds are not actively growing. 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
Susceptible weeds 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.
Restrictions
Rainfall
:
Do not apply if rain is expected in 3 hours.
Grazing
:
Do not graze treated canola, CLEARFIELD XCEED canola or cut for hay; sufficient data are not available
to support such uses. Field peas treated with Odyssey may be fed to livestock 30 days after application.
Pre-harvest Interval
:
After 60 days, bird’s-foot trefoil, canola, field peas, fenugreek (for seed uses only) and lentils
can be harvested. Only apply Odyssey once per year.
Re-cropping
:
Barley, CLEARFIELD canola, canary seed, chickpeas, durum wheat, field corn, field peas, lentils
(
incl. CLEARFIELD lentils), oats, spring wheat and XCEED 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
ODYSSEYWDG 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 drinking
water supplies or aquatic habitats by 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.
