| Abstract/Contents: | "The entomopathogenic nematode Steinernema scarabaei has shown exceptional efficacy for the management of white grub, the root-feeding larvae of scarab beetles. To improve predictability of S. scarabaei applications we studied the effect of 7 soil/substrate types and soil moisture levels on its efficacy and persistence. In laboratory and greenhouse experiments, S. scarabaei infectivity and efficacy was not strongly affected by substrate type but tended to be the highest in a loamy sand, did not differ significantly among sandy loam, loam, silt loam, and clay loam, and tended to be the lowest in highly acidic blueberry sand (pH 3.9) and a typical potting mix (69% OM). S. scarabaei persistence was high over the same range of soil types with a clear decline only aft 140 d at room temperature and without a clear effect of soil type. Only in the finest textured soil, clay loam, did S. scarabaei show a clear decline with about 50% less recovery than after 0 d. The effect of soil moisture levels ranging from saturated to very dry (-1 to -3,000 kPa water potential) on S. scarabaei infectivity was studied in a laboratory in 3 selected soils. In loamy sand, there was no strong effect of soil moisture. Even at -3,000 kPa 70% of the grubs were killed. In sandy loam and silt loam, the mortality and inefectivity were highest at -10 and -100 kPa, lower at -1 and -1,000 kPa, and the lowest at -3,000 kPa. This effect was stronger in silt loam than in sandy loam. In the same soils moisture levels of -10 to -3,000 had no strong effect on S. scarabaei persistence." |
