Abstract/Contents: | "Preplant fumigant nematicides have traditionally been used to control Meloidogyne spp. and Mesocriconema xenoplax in peach in the Southeast. In recent years growers have faced economic hardships, making it difficult to afford costs associated with these chemicals. Finding an alternative to control these nematodes is warranted. Greenhouse trials were conducted to evaluate the susceptibility of E+ and E- tall fescue grass to M. incognita and M. xenoplax. Fescue lines evaluated included, i) Jesup EI (E+, wild-type endophyte present), ii) Jesup EF (E-, no endophyte present), iii) Max-Q (E+, but non-ergot producing endophyte), and iv) GA-5 (E+). Peach was included as the control. Nematode reproduction criteria were used in evaluating fescue susceptibility. Peach supported greater (P < 0.05) reproduction of M. incognita and M. xenoplax than all fescue lines. Differences in reproduction were not detected among the fescue lines for either nematode. All fescue lines were either poor or nonhosts for M. incognita and the endophyte does not appear to effect nematode reproduction. In contrast, M. xenoplax reproduction was detected in the fescue lines. An initial test evaluating Max-Q for susceptibility to M. hapla indicated that Max-Q did not support M. hapla reproduction compared to a tomato control. These results provide useful insights into the potential use of tall fescue grass as a preplant alternative to chemical control of Meloidogyne spp." |
