Turf disease and stress resistance activators: Field work

Principle Researcher

Dr. Tom Hsiang, Dr. Paul Goodwin

Project Scope:

This project will test different defense activators on a variety of turfgrass cultivars in field studies to determine their effect on prevalent plant diseases such as dollar spot or fusarium patch and to modify the concentrations and timing needed for successful application. This will be accomplished through extensive field studies that would replicate actual use of a defense activator to induce resistance to plant pathogens. In addtion, lab tests will examine the efficacy of different activators on different bentgrass cultivars for reduction of drought, cold and heat stress. From the results of the field and lab studies, the researchers will use data collected to modify concentrations and application times and then test these recommendations again on different cultivars to see whether diseases such as fusarium patch and cool season stresses can be sufficently managed by defense activator agents. The results will provide recommendations for turfgrass managers on the choice of bentgrass cultivars and on improved turf disease and turf stress management practices.
