Turf Program Overview

The primary goal of my extension and outreach program, which is funded by the Giustina Turf Endowment, is improving the environmental and economic sustainability of turfgrass management. Topics of interest related to this include, utilization of sustainable turfgrass varieties and cultivars, improving fertility and irrigation efficiency, and the use of pesticide alternatives. I will be involved with the development and implementation of integrated pest management programs designed to reduce pesticide use.
