Application Tips
When weeds are under extreme drought stress or showing effects of excessive moisture, control can be reduced or
delayed. Weed escapes may occur under prolonged stress conditions or low fertility. Do not apply to weeds stressed
for more than 20 days due to lack of moisture as unsatisfactory control can result. Ensure uniform spray coverage
over the entire area of target weeds.
How it Works
Clopyralid is a growth regulator type of herbicide. It is primarily absorbed through the foliage and is translocated to
all parts of the plant causing leaf and stem twisting and yellowing and then death. MCPA is a systemic herbicide for
broadleaf weeds, which is translocated throughout the plant causing rapid undifferentiated growth, which usually
results in the death of susceptible weeds.
Expected Results
Weeds start to twist after spraying; then, plants turn brown and die. Difficult to control weeds such as Canada thistle
and wild buckwheat stop growing, change colour to dark green and then turn yellow before they die. Death may not
occur for 14 - 21 days after application. Some weak Canada thistle regrowth may occur by end of season.
Restrictions
Rainfall
:
Do not apply if rain is expected in 6 hours.
Grazing
:
Do not cut or graze treated fields of wheat, barley, oats or flax within 7 days after application.
Pre-harvest Intervals
:
Do not harvest wheat, barley, oats or flax within 60 days after application or within 7 days
after application when harvesting for forage. Withdraw meat animals from treated fields at least 3 days before
slaughter.
Re-cropping
:
Fields previously treated with Curtail M herbicide can be seeded to wheat, barley, oats and rye
(
not under-seeded to forage legumes), canola, corn, field peas, flax, forage grasses, mustard, sugar beets or can be
summer-fallowed in the following year. Do not seed to field peas for at least 10 months following treatment. Very dry
soil conditions following application can result in a risk of injury to field peas grown in rotation. If severe drought
conditions are experienced during the months of June to August inclusive in the year of application, delay seeding
field peas an additional 12 months (total 22 months following application).
