Uncontrolled Weeds Cause 70% Yield Loss

The Weed Science Society of America reports that yield loss for dry bean and sugar beet crops in weedy, uncontrolled plots is 70%. The long-term studies of dry beans and sugar beets determined that every dollar invested in weed management produced significant returns: an estimated $12 and $23 for growers of dry beans and sugar beets, respectively. The study found that the most troublesome weeds in those crops include common lambsquarters and kochia, as well as species in the pigweed (Amaranthus) and nightshade (Solanum) genera.
