Common dandelion (Taraxacum officinale) and field horsetail (Equisetum arvense) continue to be troublesome weeds in Wisconsin and are common in no-till fields. Two factors contributing to a resurgence of these weed species are reduced tillage and changes in herbicide programs in corn and soybeans. We have conducted on-farm trials on dandelion and off-farm trials on field horsetail for the past several years, the results of which will be presented here.
