* With at least 2% organic matter
On dormant cane, a surfactant may be added to the spray
mixture to increase control of emerged weeds.
WEEDS CONTROLLED
VELPAR® DF is recommended for the control or
suppression of the following species in sugarcane crops:
* Suppression – a visible reduction in plant population and/or plant vigor
as compared to an untr
ea
ted area and generally not accepted as control.
USE PRECAUTIONS - SUGARCANE
Do not plant any crop other than sugarcane following an
application of VELPAR® DF.
Do not feed sugarcane forage to livestock.
Do not apply VELPAR® DF:
- Within 180 days of harvest in Hawaii.
- Within 234 days of harvest in Louisiana.
- Within 288 days of harvest in Puerto Rico.
- Within 234 days of harvest in Texas.
To avoid injury to sugarcane, observe the following
precautions:
- Do not use VELPAR® DF on cane that shows poor vigor
because of insect damage, disease, or winter injury, or
shows symptoms of other stress conditions such as
drought stress.
- Do not add a surfactant in applications unless otherwise
specified.
- Do not use VELPAR® DF on gravelly or rocky soils,
thinl
y covered subsoils, or coarse-textured soils (sands to
sandy loams) with less than 1% organic matter.
- Temporary chlorosis of the crop may result from
application over emerged cane. Applications during active
cane growth should be directed to cover the weeds and
soil while minimizing crop contact.
- Do not use VELPAR® DF on varieties known to be
susceptible to herbicides.
Extremely heavy rainfall after application may result in
poor weed control and/or crop injury, especially if the
application is made to dry soil.
