Answers:
PHOTO A: The green depressions on the first cut of rough are a result of excessive levels of plant growth regulator. While applying a PGR to this golf course, the spray rig’s nozzle and nozzle body were knocked off during transport, producing a steady flow of PGR from the damaged boom. Since the fairways were creeping bentgrass, they showed no real damage from the high rates of application; in fact, the areas turned dark green. However, the Kentucky bluegrass rough areas that received the same high rate of PGR experienced substantially slowed growth and turned brown in a straight line, also causing the green depression.

PHOTO B: The holes in this brand new bentgrass golf green were created by hailstones and not a golf lesson gone terribly wrong. An intense hail storm in El Reno, Okla., produced golf ball-sized hail that riddled the golf course and greens with hundreds of thousands of quarter- and half-dollar-sized holes. This very energetic superintendent decided to take one green and put range balls in each large hole to show the vast number of hailstones that fell and they damage they caused. The top photo shows the results of his efforts, and the bottom photo shows the actual hail damage. Photo courtesy of Michael S.
