Herbicides
Water Volume
:
Fixed boom sprayer: 100 - 1,000 L/acre. Use enough water to uniformly cover the area to be treated.
Handgun: 646 L/acre.
Application Tips
If dense growth is present, results will be improved if vegetation is removed before treatment. Do not apply closer
than 1.5 times the height of nearby trees. Roots from large trees may extend well beyond the height of the tree and
may extend beneath areas to be treated. Be cautious where trees are in close proximity to the treatment site. Do
not apply to brush standing in water, lawns, walks, driveways, tennis courts or similar areas. Applying, draining or
flushing equipment too near feeding roots of susceptible vegetation may cause injury. Thoroughly clean all traces of
Hyvar from application equipment immediately after use.
How it Works
Bromacil is readily absorbed through the roots but much less readily through the leaves. Once in the plant, it inhibits
photosynthesis.
Expected Results
Susceptible plants become chlorotic and then die. Effects are slow to appear and may not become apparent until the
chemical has been carried into the root zone of the weeds by moisture. The degree of control and duration of effect
will vary with the amount of chemical applied, soil type, rainfall and other conditions.
Restrictions
Rainfall
:
Rainfall required to carry the chemical into the root zone where it is absorbed.
Environmental Precautions
Bromacil is slightly toxic to aquatic organisms, including fish. Do not apply directly to water or contaminate water
when cleaning equipment.
Runoff
:
Avoid contamination of aquatic areas as a result of runoff.
Leaching
:
Bromacil is known to leach through soil and has been found in groundwater as a result of normal field
use. Users are advised not to apply in areas where soils are permeable, particularly where groundwater is used for
drinking water.
Drift
:
All crops and ornamentals are sensitive to this chemical. Avoid drift to the desirable plants. A buffer zone is
required between the application site and sensitive areas.
Toxicity
Low acute mammalian toxicity. Acute oral LD
50
(
rats) = 2,000 mg/kg. Hyvar is a moderate eye irritant. Intake of
Hyvar can cause damage to lungs, liver, heart and kidney and can lead to a coma. May also cause blindness.
Storage
Hyvar X: Store in a cool, dry place. Hyvar X-L: Combustible, keep away from heat or open flame. Do not allow to
freeze.
