HYVAR® X-L herbicide is a water soluble liquid to be mixed
in water and applied as a spray for weed control in non-crop
and industrial sites. It may also be applied either undiluted or
diluted with water for the control of various species of brush
on industrial sites. HYVAR® X-L is an effective general
herbicide providing residual control of many annual weeds at
low rates and perennial weeds and brush at higher rates. It is
particularly useful for control of perennial grasses.
After mixing with water HYVAR® X-L is non-flammable,
non-volatile and non-corrosive to metals, except aluminum.
Use with aluminum spray nozzles or equipment is not
HYVAR® X-L is absorbed through the plant roots. Effects
are generally slow to appear and may not become apparent
until the chemical has been carried into the root zone of the
weeds by rainfall or irrigation. Moisture is required to activate
HYVAR® X-L in the soil. Best weed control results are
obtained when the soil is moist at application and rainfall or
irrigation occurs after application. Where limited rainfall
occurs during the period of active weed growth, HYVAR®
X-L usually will not provide satisfactory control of hard to
kill, deep-rooted perennial weeds, such as, Johnsongrass.
Degree and duration of weed control depend on: rate used,
weed spectrum, growing conditions at and following time of
treatment, soil texture, organic matter, soil moisture at the
time of treatment and precipitation following treatment.
Where a rate range is shown, use the higher range of rates on
hard-to-control species, fine textured soils and soils high in
organic matter or carbon. Use the lower range of rates on
annual weeds and other susceptible species, course textured
soils and soils low in organic matter or carbon. Refer to the
specific use sections of this label for rate ranges.
