Abstract/Contents:"Effective control of plant parasitic nematodes (PPNs) relies on accurate identification of the species and depth in the soil profile that species resides in. Understanding potential seasonal migratory patterns of PPNs, specifically the elusive Hoplolaimus spp., on golf putting greens is crucial to developing control methods that are useful and effective. Soil samples from varying depths were extracted on creeping bentgrass putting greens across Missouri that exhibited high counts of Hoplolaimus spp. populations in the past throughout the year to better understand the dynamics of PPN populations in the soil profile across seasons. Using a 1.9 cm. diameter soil sampler, five soil horizons were established with respective 5 cm. increments (0-5 cm., 5-10 cm., etc.) down to a total depth of 25.5 cm. A semi-automatic elutriator was used to process 100 ccs of each sample which was then poured into 50 mL plastic tubes and centrifuged at 2100 rpm for 5 minutes. Following centrifugation, the liquid layer was decanted, filled with water to level, and 20 mL of 40% sucrose solution was added. Samples were agitated and homogenized using a glass rod and vortexed for 4-5 seconds, the placed back in the centrifuge at the same rate to suspend nematode populations. The remaining liquid was poured onto a #500 sieve and the sediment was collect into new tubes for examination. One mL of solution was plated onto a hemocytometer for counting using unique morphological characteristics as keys for identification. This process was initialized in April and will be repeated in June, August, and October at each site to determine changes in population density at different depths in the soil profile throughout the year."
