Brief Project Summary:

Weed control is becoming a larger issue in South Dakota with the emergence of herbicide-resistant weeds. Herbicide resistant and difficult to control weeds are causing yield loss and significant management costs to soybean farmers. Project objectives include: surveying growers to determine new and old weed problems; establishing demonstration plots to provide today's best options for weed management; examining Palmer amaranth biology and competitiveness; studying the interaction of drift rates of auxin-type herbicides on nodulation and nitrogen fixing ability in non-resistant soybean cultivars; and determining if nigrogen application can mitigate yield loss.
