3.6.2.6 Noxious Weed Control <br />Trapper's noxious weed managemern plan may include appropriate cultural, mechanical, biological or <br />herbicidal control methods. In some cases, only one cornrol method may be warranted, while in other <br />cases a combination of cornrol methods may be appropriate. <br />The herbicides used in controlling broad-leafed noxious weeds at Trapper Mine include, but are not <br />limited to, KreniteS, Escort, Tordon 22K, Banvel, Arsenal, and 2,4-D (amine form). Herbicide may be <br />applied to the noxious plants during their post-emergence form in the spring, bud to early blossom stage <br />during the early summer months and/or during regrowth in the fall. Appropriate rates as recommended <br />by the manufacturer and the extern of yeary infestations regulate the amount of herbicide to be applied <br />in weed-infected areas at Trapper Mine. <br />Herbicides are applied with atractor-mourned sprayer, powered by tractor hydraulics, or equipment pro- <br />viding similar controlled application. <br />Reclaimed areas not yet seeded and supporting a substarnial noxious weed population may be disced, <br />mowed, sprayed, or otherwise destroyed. If noxious weed infestations occur on revegetated areas, <br />appropriate cornrol measures may be taken to control infestations (e.g. spot spray with appropriate <br />herbicide). Herbicide or other weed cornrol applications will not normally be applied to the first two <br />growing seasons after seeding to avoid unnecessary application and destruction of established target <br />natural plants. <br />The following plants may be considered to be noxious weeds at Trapper Mine: <br />Common name Sciern'rfic name <br />Leafy spurge Euohorbia esula <br />Canada Thistle Cirsium arvense <br />Musk Thistle Carduus nutans <br />Plumeless Thistle C. acarnhoides <br />Scotch Thistle Onopordum acarnhium <br />Perennial Sow Thistle Sonchus arvensis <br />Russian Knapweed Certtaurea repens <br />Spotted Knapweed Cernaurea maculosa <br />Diffuse Knapweed Ceutaurea diffusa <br />Yellow toad flax Linaria vulgaris <br />Dalmation toad flax L. genistifolia dalmatica <br /> or L. dalmatica macedonia <br />Hoary cress (white top) Cardaria draba <br />Field bindweed Convolvulus arvensis <br />3-77 <br />
