"Fusarium cannot be effectively stopped with fungicides," Ohm says.
"I think controlling fusarium in the future will require a combination
of host resistance and some fungicidal application."
The fusarium research is expected to continue for another 5 to 7 years,
but Uphaus says preliminary results have already identified several
strains that are resistant to fusarium.
Ohm has noted another benefit.
"The wheat in the misted area was several inches taller than in the
non-misted area of the nursery," says Ohm, who estimated a yield rate
of 100 bushels per acre, compared with a 60-bushel rate in the non-misted
wheat.
Thousands of different genotypes are represented in the nursery plot
at the agronomy farm, but that is only a portion of Ohm's fusarium research.
Test plots are also being grown throughout Indiana's varied soil and
climate types. Ohm monitors other test plots near Evansville, Woodburn
(east of Fort Wayne), Wabash, Romney, Vincennes and at the Pinney-Purdue
Ag Center near Valparaiso.
