Several areas of minor infestations of musk and Scotch thistle, hounds <br />tongue, and loco weed have been identified. <br />A cornbination of Banvil (dicamba) plus 2,4-D will be applied to the thistle rosettes before [he thistle bolts. <br />Rate of application, as recommended by CSU Cooperative Extension, is 0.5 quarts Banvel plus 1.0 quarts <br />2,4-D per acre. Mechanical control will be used after the terminal head is in tfte late flowering stage. The <br />cut debris will be gathered and burned to destroy any seed [hat has developed. <br />Hounds tongue is a biannual weed. 2,4-D (1.5 quarts per acre) will be applied to the rosettes during the <br />first year of growth. Plants in the second year of growth generally must be controlled by mechanical <br />means. <br />Loco weed generally has been found on undisturbed grass lands adjacent [o reclaimed areas. Roundup, <br />isopropylamine salt ofN-(phosphonomethyl) glycine, mixed @ 2.66 oz. per gallon of water, will be <br />applied directly on [he flowering plan[. <br />Please contact me if you need any additional information. <br />Sincyryly, <br />~~~ <br />Ronald G.
