Crop safety
:
Applications of Achieve Liquid Gold to non-tillered crops exposed to 4°C temperatures before or
after spraying should be avoided to prevent the possibility of crop injury. Tillered cereal crops may incur injury if
Achieve Liquid Gold is sprayed within 48 hours of freezing temperatures.
How it Works
Achieve is a systemic herbicide that is absorbed through the leaves and translocated to the growing points within the
plant where it starts killing the susceptible grasses. Thorough coverage of the foliage is important for consistent grass
control. Mextrol 450 contains two components, bromoxynil and MCPA. Bromoxynil is a contact herbicide inhibiting
respiration and photosynthesis of the susceptible weeds. MCPA is a systemic herbicide absorbed through foliage and
roots and is readily translocated to the actively growing regions of the plant.
Expected Results
Grassy weeds: growth stops in 48 hours. Young shoots turn brown in 7 - 8 days. Complete death of plant will take
2 - 3
weeks. Broadleaf weeds: small burnt spots on the leaf can appear within hours; death takes up to two weeks.
Poor results may be expected as a result of poor coverage or poor penetration through canopy.
Restrictions:
Rainfall
:
No effect 1 hour after application.
Grazing
:
Immature cereal crops may be grazed, harvested or cut for hay 16 days after treatment. Mature straw may
be fed to livestock. Do not feed or graze underseeded forage crops in the year of treatment.
Pre-harvest Interval
:
Immature cereal crops may be grazed or cut for hay 16 days after treatment. Grain may be
harvested 60 days after treatment. Mature straw may be fed to livestock. Do not feed or graze underseeded forage
crops in the year of treatment, sufficient data are not available to support this use.
Re-cropping Restrictions
:
Do not replant treated areas to tame oats or corn for at least 4 weeks after application.
Other Crops: none.
Environmental Precautions
Do not apply to any body of water. Avoid drifting of spray onto any body of water or other non-target. Do not apply
within 15 m by ground and (50 m by air) of non-crop areas. This includes fish-bearing waters, wetlands (potholes,
sloughs etc.) and wildlife habitat (hedgerows, rights of way, etc.).
