for disrupting plant establishment and growth. To avoid development of weed <br />resistance to a particular herbicide through repeated use over prolonged periods of <br />time, GCC will use a combination of chemical methods. These methods include the <br />use of herbicides and plant growth regulators with different modes of action in <br />rotation, tank mix or in sequential applications. Also, herbicides will be applied at <br />the manufacturer's recommended treatment concentration to prevent development <br />of plant resistance. <br />The entry of herbicides into surface waters will be prevented, with adequate buffer <br />strips being used when application occurs in proximity to water bodies. If herbicide <br />use becomes necessary within riparian corridors, hand application on specific <br />targets will be employed with products approved for riparian application. <br />1.4 Education <br />GCC will educate field personnel in weed identification, and accepted control and <br />eradication methods and practices. Field personnel will be familiarized with the <br />Plan to encourage compliance with weed management program goals. An <br />important part of the education process is the safe use and storage of pesticides, <br />including restricted entry intervals and record keeping. If weed control contractors <br />are used on the project, GCC will closely supervise their compliance with the Plan, <br />including safe and proper use of herbicides and appropriate disposal methods. <br />1.4.1 Pesticide Safety <br />Successful IPM begins with an understanding of the target plant species and the <br />environment within which it grows. Next the herbicides physiologic affects on plant <br />growth and development must be understood. Understanding a pesticides chemical <br />nature is also important in minimizing impacts to non-target species, the applicator, <br />GCC Red Rocks Mine 8 03/03/03 <br />
