Application Information
How to Apply
:
Ground applications only.
Do not apply by air.
Water Volume
: 40 - 223
L/acre.
Application Tips
Apply in sufficient water (40 - 223 L/acre) to wet all foliage during periods of active growth. Do not mix or store
in unlined steel (except stainless steel) containers or spray tanks. Do not use where roots from desirable vegetation
may extend into the treated area. Maintain a distance from desirable trees equal to at least twice the distance from the
trunk to the drip-line. Do not apply where runoff water may flow onto agricultural land.
How it Works
Absorbed by both roots and foliage of sensitive vegetation. Translocated throughout the plant including the root
system in both the xylem and the phloem. Non-selective. Plant stops growing shortly after application.
Expected Results
Plants stop growing within 24 - 48 hours. Yellow, purplish and/or red discolouration of the leaves may occur. The
growing point of the plant and the youngest leaves begin to die first, with symptoms eventually progressing to older
leaves. Chlorosis and tissue necrosis may not be apparent in some plant species until 2 weeks after application.
Complete kill of plants may not occur for several weeks.
Restrictions
Rainfall
:
Rainfall within 2 hours may decrease foliar activity. Rainfall does not affect root activity or the control of
non-emerged sensitive species.
Grazing restrictions
:
Do not graze the treated area or cut for hay.
Re-cropping Restrictions
:
Non-crop/non-graze applications only.
Environmental Precautions
Arsenal is toxic to non-target aquatic and terrestrial plants. Leave 20 metres from the downward edge of the spray
boom to sensitive terrestrial habitats. (Buffer zones for protection of terrestrial habitats are not required for use on
rights-of-way, including railroad ballast, rail and hydro rights-of-way, utility easements and roads). Do not apply
where runoff water may flow onto agricultural land as injury to crops may result.
Toxicity
Low acute mammalian toxicity. Acute oral LD
50
(
rats) 5,000 mg/kg. Non-toxic to fish, birds and bees.
Storage
Store above -12°C. Arsenal should not be mixed or stored in unlined steel (except stainless steel) containers or spray tanks.
