Abstract

In 1989, the USDA began experimenting with cattail management to reduce sunflower damage caused by blackbirds. Dense stands of cattail, which often hold large numbers of blackbirds in late summer and early fall, were thinned with glyphosate-based herbicide. Based on promising results from initial research, a statewide cattail management program was started by the USDA in 1991.
