For these types of herbicide applications, two types of chemicals account for the majority of use. <br />• Glyphosate is the non -selective herbicide primarily used in the City's parks for spot <br />spraying. "Roundup" is a common Glyphosate brand people associate with this <br />chemical. Glyphosate is one of the most commonly used non -selective herbicides. <br />• 2,4-D (2,4-Dichlorophenoxyacetic acid) is the selective herbicide primarily used in the <br />City's parks for broadleaf control. There are many choices for selective control but 2,4-D <br />remains one of the commonly used and most effective herbicides. <br />Whichever application is used, all herbicides are applied in compliance with Environmental <br />Protection Agency (EPA) regulations. The City only uses herbicides that are legally registered by <br />the EPA and applied in compliance with EPA regulations. All City applicators are either licensed <br />or monitored by a qualified supervisor licensed by the Colorado Department of Agriculture for <br />applying pesticides. <br />Staff remains open to this discussion and potential changes to current practices and would like <br />the Board to be aware of trade-offs and past experience. <br />Staff recommends that past experiences have shown that modifications or incremental changes <br />to the current program have a better chance for long-term acceptance. In 2008, herbicide use <br />stopped for a period of time and shortly thereafter the community's reaction caused a reversal <br />of this action. This reversal occurred due to the community not supporting the trade-off <br />between reducing herbicide use and the resulting appearance of parks. <br />Next Steps: <br />After review and discussion by PPLAB, staff will review any recommendations for possible <br />adoption into current practices and report back to PPLAB as a staff update. <br />15 <br />
