Prodiamine Application

Last week the Stadium staff performed our first application of Prodiamine on all maintained turf areas on the Stadium golf course. Prodiamine is a pre-emergent herbicide that is applied for the preventative control of many grass and broadleaf weeds that are commonly found in Bermudagrass. This pre-emergent comes in both a granular and liquid form. The majority of the application was in liquid form while more precise areas that could not be reached with the spray rig was applied granularly. It is important that we apply Prodiamine in the fall/winter months because of the mode of action of this particular pre-emergent. Prodiamine works by inhibiting the steps in plant cell division which are responsible for cell wall formation. Because of this mode of action we do not want to apply this herbicide in the spring or summer because we are trying to grow dense, lush stands of turf which would not be possible if their roots were being inhibited. In the fall and winter when the growth of the plant is slowed, the herbicide does not affect the turf itself as much. Approximately 90 days after our first application, (December) we will perform our second and final application of Prodiamine for the year.

Granular Prodiamine had to be walk spread around green surrounds, trees and heavily undulated areas where the spray rig could not safely apply the pre-emergent.
