Figure 1 shows areas with noxious weed infestations <br />that were treated in 2005. Canada thistle (Cirsium arvense) and Houndtongue (Cynoglossum <br />officinale) were the primary tazget species, however, Yellow toadflax (Linaria vulgazis) was <br />treated in Parcel 003. The applied herbicide consisted of a tank mix of 0.5 gallons of Tordon 22K <br />and 0.5 gallons of 2,4-D with 50 gallons of water. Control areas were sprayed in June and, then <br />again in September. A spot spray gun was used to concentrate control activities on target azeas, <br />reducing potential impacts to adjacent desirable vegetation. The weed control areas will continue <br />to be monitored in 2006 for effectiveness and necessary retreatment. <br />Hydro-Environmental Solutions, Inc. <br />P.O.
