Application Information
How to Apply

Apply with ground equipment only. Do not apply by air.
Water volume
: 81
L/acre.
Application Tips
Do not apply to frozen soils or soils with less than 1% soil organic matter. Do not use on fields that will be seeded
to other crops within 24 months of application. Do not apply to slopes as soil erosion may occur. Best results are
obtained when Velpar is present in the root zone during active growth of the target vegetation. Symptoms usually
appear in herbaceous plants within 2 weeks after application under warm, humid conditions, while 4 to 6 weeks may
be required when weather is cool. If rainfall after application is inadequate to activate Velpar in the soil, plants may
recover from contact effects and continue to grow until sufficient rainfall moves Velpar into the root zone.
How it Works
A systemic herbicide readily absorbed through the roots and foliage and translocated upwards. Inhibits
photosynthesis.
Restrictions
Rainfall
:
Rainfall is beneficial for activation of product.
Grazing
:.
Do not apply within 30 days of harvest (cutting for hay) or feeding of forage or grazing.
Re-cropping
:
Information enabling specific recommendations for rotational crops and re-cropping intervals is
limited. Do not seed any crop following alfalfa that has been treated with Velpar L herbicide until a successful field
bioassay shows that the crop in question may be grown safely. A successful field bioassay means growing to maturity
a test strip of the crop across the field.
