If your photograph is selected, you will receive full credit. All photos submitted will become property of GCM and GCSAA. This brown and thin turf is a result of ground pearls. For those of you who have never encountered these root zone-inhabiting pests, they are no treat. This golf course in Costa Rica has sand-capped paspalum fairways and, for some reason, ground pearls have become problematic in some areas — mostly in the trap fingers and on fairways. The superintendent's IPM program includes scouting and mapping. When the insect numbers reach an unacceptable level, the damaged sod is removed from these areas and an imidacloprid granular insecticide is incorporated into the soil before re-sodding. This must be performed before the ground pearls develop their waxy coating and stop feeding. In areas like trap fingers, the team has also re-sodded with zoysiagrass, which seems to be less appealing to the ground pearls and be more resistant to damage. The superintendent also reports, "If they get into my greens, I will be retiring and renting surfboards from a shack on the beach!"

PROBLEM B The marks on this putting green are obviously vandalism — graffiti, to be exact. Even though this quiz is easy to figure out, I had to show the photographs because I had never seen this type of vandalism before and neither had the assistant or the super- intendent. This golf course is located in southwestern Norway and is ranked seventh in the country; the superintendent has had to deal with minor vandalism from time to time over the years, but never anything quite like this. It appears that a foursome of graffiti artists decided to tag this golf green with their own brand of artwork. We cannot be sure if "Green Violence" is their gang name or a literal statement. The painted area was flushed with a hand-held hose, and then a wetting agent was applied and watered into the soil. Next, crew members used a mid-strength brush to gently remove some of the paint. These steps seemed to work: The grass didn't turn yellow or brown, and within two weeks it was back to normal.

We engineered a counter-balanced handle so the cutting reel sits true on the turf when you grab the handle. We put in password protected programmable controls so you can achieve a consistent cut regardless of operator. We rotated the Honda® engine 180 degrees so you get better balance in turns and easy access to the pull-start. We installed a true automotive differential so you get superior straight line tracking. WE PUT MORE INTO IT. YOU GET MORE OUT OF IT. We installed regenerative braking so you can control speed when mowing. We extended the mounting slots so you can adjust weight distribution to the front roller. We put in our Classic XPTM reel with 15-blades so you get the industry's best quality of cut. ECLIPSE2 ® 122F model shown We increased the maximum mow speed to 3.8mph and added a 15-blade reel so you can be more productive without sacrifi cing quality of cut. We put in our patented true fl oating head so you can cut the most undulated green without scalping. ©2012 Jacobsen, A Textron Company/Textron Innovations Inc.
