用地毯滚筒将除草剂涂抹在灌木的茎和叶上，对蜂蜜的防治效果进行了评价。瓦尔&nulosa(Torr.)Cockwell]在4个地点。无论在春季还是秋季使用，PI&ram(4-氨基-3，5，6-三氯烟酸)和elopyrnlide(3，6-二氯烟酸)在所有地点都能最大限度地杀死蜂蜜。在德克萨斯州南部干旱条件下处理的植物中，有38%的植物在德克萨斯州中部经历了最适宜的生长条件，在这些植物中，使用匹克灵处理的植物的死亡率(根部死亡)不等。根据治疗后第二个生长季接近尾声时的死亡率，氯吡虫酯的效果相当于或略高于pi&ram，而草甘膦[N-(膦甲基)甘氨酸]和三氯吡啶([(3，5，6-三氯-Z-吡啶基)氧基]乙酸]的效果通常较差。除草剂有效成分含量120g/L的药液比药效30g/L的药液效果好，但有时差异不大。与在密林中生长的较大的植物相比，铺着地毯的滚筒更容易控制小的、分布广泛的蜂蜜介体。
A carpeted roller, designed to wipe herbicide solutions onto brush stems and foliage, was evaluated for control of honey mesquite [Prosopis ~ulifora (Swartz) DC. var. &ndulosa (Torr.) Cockwell] at 4 locations. Pi&ram (4-amino-3,5,6-trichloropicolinie acid) and elopyrnlid (3,6-dichloropicolinic acid) top killed honey mesquite at all locations, whether applied in spring or fall. Mortality (root-kill) of plants treated with picloram varied from 38% of plants treated under drought conditions in south Texas to 97% of plants experiencing optimum growing conditions in central Texas. Clopyralid was equal to or slightly more effective than pi&ram, based on mortality near the end of the second growing season after treatment, whereas glyphosate [N-(phosphonomethyl)glycine] and triclopyr ([(3,5,6-trichloro-Z-pyridinyl)oxy] acetic acid] were usually less effective. Solutions containing 120 g/L of herbicide active ingredient were more effective than solutions containing 30 g/L, but differences were sometimes slight. Small, widely spaced honey mesquites were more easily controlled with the carpeted roller than larger plants growing in dense stands.
