• V.L. Weed Management
`Weeds' broadly refers to unwanted vegetation. Various methods of control include 1) planting of
desirable vegetation, 2) alteration of growth environment, 3) mechanical removal, 4) biological
control, and 5) chemical control. The method or combination of methods used depends on the
weed species, growth stage, location, regulatory designation (i.e. is it classified as noxious and if
so, is it on List A, B, or C), extent of infestation, and availability of the equipment or chemical for
control. It is not our intent to identify what methods will be used in every situation within this
permit. Doing so would only serve to limit BME's ability to adapt to unique situations.
Rule 4.18(5)(8) requires Division approval for use of 'persistent' pesticides. Non-persistent
pesticides such as 2,4-D and glyphosate (Roundup) do not fall into this category requiring specific
Division approval. Persistent pesticides approved by the Division for use at the Deserado Mine
include picloram (Tordon), imazapyr (Arsenal), imazapyr +diuron (Sahara), bromacil (Hyvar),
bromacil +diuron (Krovar), tebuthiuron (Spike), imazapic (Plateau), imazapic +glyphosate
(Journey), metsulfuron (Escort), and chlorsulfuron (Telar).
Tordon is used primarily for noxious weed control. Canada thistle is the primary target weed but
Tordon is also very effective on Russian knapweed, field bindweed, and black henbane. As a
'restricted' pesticide special licensing requirements apply to Tordon's use.
• Arsenal is used primarily for the cut stump treatment of saltcedar and Russian olive and for bare-
ground weed control around facilities. Foliar application to saltcedar and Russian olive may also
be effective for spot control of young plants and resprouts. Arsenal is also particularly effective in
controlling field bindweed. The vegetation control characteristics of Arsenal persist for several
years. This product will not be used for bare-ground vegetation management in areas scheduled
for reclamation within three years.
Spike, Sahara, Hyvar, and Krovar are used for bare-ground weed control. The vegetation control
characteristics of these products can persist for several years. Their use will be the control of
vegetation along railroad tracks, areas immediately surrounding flammable storage tanks and
electrical substations, and where vegetation may cause safety, fire, or structural integrity
concerns. These products will not be used in areas scheduled for reclamation within three years.
Plateau and Journey are used primarily for cheatgrass control. These herbicides are also
effective in controlling leafy spurge, whitetop, Perennial pepperweed, and Russian knapweed.
Further research and experience with these herbicides will help dictate how they will be
integrated into the revegetation program.
Escort and Telar are effective in controlling many annual broadleaved weeds, biennial thistles,
whitetop, and perennial pepperweed. These herbicides are particularly effective on members of
• the mustard family.
