Home My WebLink About022 - Appendix S - Weed Control - Baxter 80 January 30, 2026 Gallatin County Weed District 903 N Black Bozeman, MT 59715 RE: Weed Management Plan: Proposed Diamond 8 Sports Complex. Property description and planned use. The 80-acre subject property is located south of Baxter Lane and north of Oak Street, Bozeman Montana. Access to the property is off either Baxter or Oak via farm access. If approved for development, an extension of Laurel Lane from the south will border the property’s east side. The property is a currently undeveloped and consists of a former hay field and wetlands. A running ditch or small unnamed creek bisects the field from northwest to southeast. Patches of cattail and dense Canada thistle grow adjacent to the ditch in low lying marsh and wetlands. Some brush and small trees can be found adjacent to the creek at the south end of the property. Noxious Weeds Noted: Locations of specific weeds have been noted on the map image at the end of this document. The site survey was conducted on January 29th, 2026 and there was no snow to impede weed identification. Portions of the hay field were found with dense grass and few weeds. On the mown interior areas of the field, we found a few patches of musk thistle; sometime individual plants and some areas with small infestations of a few plants. There were no large infestations noted. Canada Thistle was prevalent primarily in the native area/wetlands along both sides of the creek. Some were scattered with musk thistle along the west fence line. Small patches and individual plants were noted in the hay field on the southwest corner of the property. A large patch of Common Tansy was found in the very northeast corner. 90 % of this tansy is on the adjacent property with some spreading onto the target property. (noted on the map) This area of tansy is small relative to the entire property and no other tansy was noted. Some hoary alyssum was found in the tall native grass along Oak Street on the southeast corner. (noted on the map) A section of the center of the interior, running north to south and about 20-30 yards wide was heavily infested with kochia and wild mustard. Prickly lettuce was also found scattered on the property. These are not noxious weeds and are not targeted unless within areas treated for noxious weeds. Environmental Considerations & Herbicide Selection. In consideration of the varieties of noxious weeds found and some low-lying wetlands adjacent to the ditch we recommend the use of Corteva’s Chaparral herbicide. Chaparral is very effective on the noxious weeds present on the property and can be safely applied to water’s edge. Herbicide will be applied at an application rate of 3.3 oz/acre with Amine 24D @ 1Qt/ac and a non-ionic surfactant such as Liberate with a 15 gallon per acre diluent rate. Application Plan: A combination of hand spot spraying and broadcasting will be required to cover the property. Small patches and individual weeds will be hand sprayed as will wetland areas close to the ditch. Larger infestations in the hayfield on the south end and will be broadcast using an ATV and 70 gallon pull behind sprayer. An estimated 28 acres will require broadcasting with the balance spot sprayed. The application will be completed between June 1st and June 15th.
