Use a glyphosate based herbicide and make sure it has a surfactant or sticker additive. For small emergent weed 'stands' a very good product it called Shore-Klear Plus. Plus meaning there is surfactant added to the product. Late summer fall is a very good time to spray the cattails for good systemic action and an effective kill rate. The leaves should turn yellow and then brown in 7-10 days. The dying cattail leaves are easiest to cut and remove before the leaves are completely brown.
