Herbicides
Brush Controlled Rate and Timing
Apply in mid June to end of July
Brush controlled at 10.0 L/1000 L of water. Add 1 - 2 L of surfactant (Tween 20)
alder
beech
elm,
maple
pine
ash
birch
hazel
oak
trembling aspen
Brush controlled at15.0 L/1000 L of water. Add 1 - 2 L of surfactant (Tween 20)
large tooth aspen,
balsam fir
cherry
hemlock
white spruce
Note: Balsam poplar and cedar may not respond to treatment at recommended rates.
Registered Tank Mixes
None.
Application Information
Apply with high-pressure ground sprayers. Do not apply by air.
Water Volume
: 200 - 1200
L/acre.
Application Tips
Use sufficient water volume to ensure good penetration to wet stems and trunks of target brush as well as leaves and
buds. A non-ionic surfactant is required to control most conifers and to control the root suckering of deciduous brush.
Thoroughly clean all traces of Krenite from application equipment after use.
How it Works
Absorbed by leaves, stems and buds. Restricts bud development the following spring.
Expected Results
Response may not be observed until the following spring, particularly if minimum recommended rates are used or if
cool temperatures prevail when spray is applied. Susceptible treated plants fail to refoliate and subsequently die.
Restrictions
Rainfall
:
If rainfall occurs within 24 hours, effectiveness may be decreased.
Grazing
:
Do not graze on land treated with Krenite
Environmental Precautions
Do not directly apply to any aquatic habitats that are traversed by the right-of-way. Do not spray ditch banks, sites
that are adjacent to and surrounding domestic water supply reservoirs, supply streams, lakes or ponds.
Drift
:
Do not allow drift or spray mist to contact desirable trees, shrubs, or other plants, as injury may result.
Toxicity
Krenite has a low acute mammalian toxicity. Acute oral LD
50
(
rats) = > 5,000 mg/kg. Krenite is a moderate to severe
eye irritant.
Storage
Store in a cool, dry place.
