92 GOLF COURSE MANAGEMENT 11.18 John Mascaro President of Turf-Tec International Presented in partnership with Jacobsen On one cool, 68-degree July morning, the material on top of this bunker sur- round startled the golf course superintendent. From a distance, he thought it was Pythium, but to his surprise, upon closer examination, it turned out to be early-morning dew on spider webs. One theory why this occurred is, on that morning, a large batch of spiderlings hatched at the same time and bal- looned, or kited, from a nearby area. This ballooning process is when spider hatchlings move through the air by releasing one or more threads of fine silk, called gossamer, to catch the wind, causing them to become airborne. This material can completely envelop trees, shrubs and, in this case, nearby grasses. The material was gone the next day, and the event has never re- peated itself. Photograph submitted by Patrick Kelley, GCSAA Class A superintendent at Abenaqui Country Club in Rye Beach, N.H., and 33-year association member. Spider facts were submitted by David Shetlar, professor emeritus at Ohio State University.

This irregularly shaped brown area on the No. 5 fairway was located very close to a wooded area, and when the superintendent saw the damage, he was determined to figure out what caused it. The superintendent solved the mystery while playing a round of golf. A golfer propping his leg on the back bumper of a golf cart had applied copious amounts of aerosol insect repel- lent to their legs as well as the turf. Since the golf cart partially shielded the turf, the results were a green area where the cart was parked and brown turf where the insect repellant was applied to the turf. The area recovered on its own in about five days without any additional inputs. Please note: The second photo is a re-enactment of the actual event, and no additional turf was actually harmed. Photograph submitted by Al Frantik, site manager at The Links at Spring Church in Apollo, Pa., and a 26-year GCSAA member. (photo quiz answers) PROBLEM PROBLEM (b) (a)
