Wheat residue decomposition was related to survival and inoculum potential of Fusarium graminearum Schw. (F.g.), causal agent of wheat scab.
Inoculated wheat residue was placed on the soil surface, at 7.5-10 cm and 15-20 cm deep in chisel plowed plots and 15-20 cm deep in moldboard plowed
plots, in October 1997 at Crookston, MN. Residue was sampled from April through November, 1998 and 1999. Stem/node pieces (1.5-cm) were plated on
PCNB agar and subsequently, colonies were transferred to carnation leaf agar to assess F.g. survival. Inoculum potential was assessed by ascospore counts
from stem/node pieces incubated at 100% RH for perithecial formation. Buried residue decomposed faster than that on soil surface, and F.g. survival
was inversely related to decomposition rate. F.g. colonization was significantly reduced by 8 mo. in the soil. Colonization of other Fusarium
spp. increased over time. Ascospores of F.g. were still produced on some residue pieces after 23 mo. in/on soil. Data from this research may assist in
developing effective management of F.g. infected residues. |
