A myriad of recently released cultivars of creeping bentgrass with more desirable agronomic characteristics are available. Traditional conversion involving the use of non-selective herbicides or soil fumigants is costly and time consuming. Interseeding has been proposed as an alternative conversion method. Interseeding is a method of conversion where seed is sown into an established grass sward. The goal is for the introduced cultivar or species to become the major component of the sward over time.
