Phosphite for Cool-Season Turfgrass Management - On Demand

Author
John Dempsey, Ph.D.
Start Date
11/6/2018
Duration
90 Minutes

Research which has produced significant and novel data on the use of phosphite as a management tool in cool-season turfgrasses is presented by John Dempsey, Ph.D. During this 90-minute webinar, he covers what is phosphite, its development for turfgrass usage, its ability to suppress common turfgrass diseases such as Microdochium patch and Anthracnose, and its effect on turfgrass growth and development. Dempsey shows that the use of phosphite in a turf management program, will not only suppress disease incidence but increase the efficacy of turfgrass fungicides and lead to an enhancement of turfgrass quality.

After attending this program, attendees will be able to:

• Describe what phosphite is, how it’s taken up and translocated within turfgrass and understand the process by which it can reduce disease incidence.
• Understand how phosphite, despite not supplying a nutritional form of phosphorus can improve turfgrass quality and lead to growth enhancement.
•  Be able to judge if the incorporation of phosphite into their maintenance program would be cost beneficial for the facility they manage.
