Golf course superintendents are continually being asked to maintain optimal playing conditions with reduced budgets. Correct implementation of certain cultural practices can often discourage weed infestations resulting in less revenue being spent on herbicide application. Cultural practices can also increase the effectiveness of herbicide applications. Jim Brosnan, Ph.D., will provide an overview of cultural practices that can discourage weed infestation in warm- and cool-season golf course turf. This 90-minute webcast also include results of research studies evaluating effects of cultural practices on herbicide performance.
