CC&V: 2015 Weed Management Report <br />with Dalmatian toadflax and common mullein towards the top of the slope around the buildings <br />and pipelines. Isolated patches of musk and Canada thistle were found throughout the treatment <br />area with the majority of the musk thistle being found on the eastern half of the treatment area. <br />Yellow toadflax was scattered throughout all the areas treated. Scotch thistle infestations were <br />identified along the eastern most part of the road that provides access through the Phase 5 area, <br />however; infestations were few and isolated All treatments were performed using 150 foot hose <br />reaching out from each side of the UTV, however; the mid-section of the slope was difficult to <br />reach due to inaccessibility of our UTV-mounted spray rig. There was a total of 4.5 acres treated <br />with the primary herbicide mixture within the Phase 5 area. <br />ALTMAN STOCKPILE <br />Treatment to the Altman stockpile was performed on September 29-30 and included all areas in <br />between the roads surrounding the stockpile. The Altman stockpile has good growth of native <br />perennial grasses with a few trees and shrubs also present. The most prevalent noxious weed <br />species treated was Canada thistle, with patches identified throughout the entire treatment area. <br />The northern end of the area near the drainage way was the most infested with several large patches <br />of Canada thistle being identified and treated. The roads at the top and bottom of the pile provided <br />good access to the treatment area using the UTV spray rig. There was a total of 2.5 acres treated <br />with the primary herbicide mixture. The mixture was adjusted by increasing the rate of Telar XP <br />herbicide to 1.5 oz. /acre to treat the perennial species Canada thistle. Increasing the rate will help <br />kill the extensive root system that has established with each Canada thistle patch. The herbicide <br />will translocate into the root system and persist in the soil which will reduce the amount of new <br />rosettes seen emerging in the spring. <br />BAITMAN TOPSOIL STOCKPILE <br />The Baitman topsoil stockpile was treated on September 30 and October 1. This area was accessed <br />by the Victor cemetery road which allowed access to the trail near the stockpile. The UTV mounted <br />spray rig was used along the trail leading around the base of the topsoil stockpile to access noxious <br />weeds from the toe of the slope. The road to the top of the topsoil stock pile provided access for <br />the UTV to treat the wide spread infestations. The treatment area was infested with common <br />mullein and was the primary targeted species. Common mullein treatments were focused on the <br />rosette stage only, as most of the plants had already produced flowers and seed. The east facing <br />slope on the stockpile was the most infested with nearly 80% cover of noxious weeds in some <br />locations. The perimeter of the eastern slope infestation was targeted to contain the infestation of <br />common mullein and prevent further spreading to adjacent areas. Furthermore, the eastern slope <br />was inspected and treated to help reduce the number of rosettes emerging from the seed bank. The <br />drainage way below the highway on the western side of the topsoil stockpile was infested with <br />Canada thistle. The entire length of the drainage way from the road to the fence line was inspected <br />and treated for Canada thistle. Yellow toadflax and Dalmatian toadflax infestations were sporadic <br />and treated throughout the area. A total 2.5 acres were treated with using the primary herbicide <br />mixture. The mixture was adjusted to help increase adhesion of the herbicide to the common <br />mullein rosettes by increasing the rate of Induce surfactant from 16 oz. / acre to 20 oz. /acre. The <br />pubescence on the leaves of common mullein plants make it difficult to treat because the herbicide <br />and water solution tends to bead up and run off the plant cuticles, thus making it difficult for the <br />plant to absorbed the chemical. Increasing the surfactant rate reduces water's surface tension and <br />spreads the herbicide solution over the leaves allowing plants to absorb the herbicide. <br />Habitat Management, Inc. 3 December 8, 2015 <br />
