Evaluation of ABG-9008 for Control of Nematode Damage to Golf Course Greens
Summary: A study was conducted on annual bluegrass golf course greens in three locations to evaluate the efficacy of two different formulations of ABG-9008 applied at two different rates for control of the damage caused by parasitic nematodes on turf. A significant (P<0.10) decrease in Criconemella populations was observed in one location, on one sampling date, but no other consistent trends towards improved turfgrass quality or reduction of parasitic nematode populations (including the ring nematode, Criconemella, the spiral nematode, Helicotylenchus, the root-knot nematode, Meloidogyne, and the stunt nematode, Tylenchorhynchus) were seen. Inexplicable, but significant (P<0.10) increases in the numbers of Helicotylenchus and Meloidogyne were observed at one location each following treatment with ABG-9008. Further lab and/or greenhouse studies may be required to understand the basis of these somewhat inconsistent results.
