Marestail has become a major weed for soybean producers in Kentucky and throughout a broader geographic range. Its small seed size makes this weed particularly troublesome for no-till soybean growers as seedlings can emerge from the soil surface. Its prolific, wind-blown seed can disperse far between fields and adjacent natural areas, while its extended emergence period also complicates timely and economical management efforts. In addition to all of these traits, glyphosate resistant biotypes are now widespread throughout the state. Thus, management tactics that integrate chemical options with cultural practices like the use of cover crops are desirable for this species. This project examines...
