The Golf Course Superintendents Association of America (GCSAA) is to fund four new research projects at universities across the USA.

The projects will receive a total of $170,064 (£136,000) from a GCSAA Foundation block grant with an additional $117,500 (£94,000) in matching funds from participating GCSAA chapters and the Oregon Turfgrass Foundation.

The four projects that will be funded are:

• Comparing wetting agent application strategies for efficacy and longevity in sand-based putting greens; by Wendell Hutchens PhD, University of Arkansas.

• Suppressing dollar spot through adjustment of leaf surface pH; by Paul Koch PhD, University of Wisconsin.

• Effects of moisture management on annual bluegrass weevil movement, oviposition, larval survival, and turfgrass damage; by Benjamin McGraw PhD, Pennsylvania State University.

• Influence of nitrogen rate on growing degree-day models for plant growth regulator reapplication interval on annual bluegrass putting greens; by Alec Kowalewski PhD, Oregon State University.
