Impact of Integrated Vegetation Management Practices on Green Antelopehorn Milkweed (Asclepias viridis Walter) in Right-of-Ways and Forages
by Thorne, Nolan Hendrix, M.S., Mississippi State University, 2018, 82; 10980086
Abstract (Summary)

Common integrated vegetation management (IVM) practices including herbicide and mowing applications on right-of-ways and forages were evaluated on green antelopehorn populations near Starkville, MS. Live stems in each plot were counted prior to treatment application and approximately one year after treatment (YAT). Analysis of the stem counts 1YAT indicated aminopyralid+metsulfuron, imazapyr, picloram+2,4-D, maximum rates of triclopyr ester or choline, glyphosate, imazapyr+aminocyclopyrachlor+metsulfuron reduced the number of green antelopehorn stems compared to the untreated. Aminocyclopyrachlor, aminocyclopyrachlor+chlorsulfuron, aminopyralid, aminopyralid+2,4-D, dicamba+2,4-D, foramsulfuron+iodosulfuron+thiencarbazone, fluroxypyr, hexazinone, metsulfuron, metsulfuron+chlorsulfuron, nicosulfuron+metsulfuron, sulfometuron, sulfosulfuron or low rates of triclopyr did not reduce the stem count 1YAT when compared to the untreated. Mowing timing and frequencies applications were initiated May through July and evaluated through August. Mowing early in the season increased milkweed stems one month after treatment versus late season mowings. Majority of milkweed plants developed mature seed pods and senesced by early August.
