John Mascaro's Photo Quiz Answers from page 17
THE BROWN TURF is a result of an army worm infestation. This year has been particularly bad for army worms in the Eastern United States and on a Friday afternoon, this sports turf manager observed a slight browning on the turf near the warning track on this 419 bermudagrass baseball field. By Monday morning at 7 am, the sports turf manager returned to the area and found that the army worms had eaten most of the right field. A bifenthrin insecticide was applied and the army worms began curling up within 30 minutes after spraying. The following day the sports turf manager applied a 21-0-4 turf fertilizer with 0.067% Acelepryn insecticide. It is unclear where the army worms came from although the field and sur- rounding area were rebuilt about 2 months before the infestation and large rolls of straw were brought in and used to stabilize the banks behind the field. Since army worms show up in large num- bers but eat mostly bermudagrass leaves, the damage was largely superficial and grew out fairly quickly after the pests were controlled.
