Phalaris species have excellent potential for cool season forage production in the southeastern USA but plant-parasitic nematodes have caused erratic performance on sandy soils. The objectives of this study were to determine prevalent plant-parasitic nematode species infecting Phalaris species and to measure the effects of these nematodes on total forage yield and distribution of yield. Forage production of three Phalaris cultivars, 'Siro 1146' hybrid (P. aquatica x P. arundinacea), 'AP-2' (P. aquatica), and 'Auburn' reed canary (P. arundinacea), was studied in a central Alabama field experiment on Cahaba fine sandy loam soil (Typic Hapludult, Fineloamy, Siliceous, Thermic). Forage yields were measured on untreated soil and on soil treated with methyl bromide (MB). Winter and early spring production of P. aquatica x P. arundinacea during the establishment year was increased 39% with MB above that grown on untreated soil, 71% for P. aquatica, and 232% for P. arundinacea.
