Does anyone have any information on specific cover crops and positive
or negative effects on verticillium wilt? The SARE/ACE Project Summaries
mention a potato project in Idaho led by Jerry Stark finding that
"Sudangrass green manure grown prior to potatoes reduced Verticillium
wilt by 60% and increased potato yields by as much as 30% compared with
fallow treatments." Any other info?

The person who asked me is considering planting olives in a cotton
field that has a Verticillium problem, and he's looking for nonchemical
ways to reduce the problem first. He asked specifically about cover
crops, but I suppose other approaches would be of interest, too.
