Soybean Rust:
What other crops might be affected by soybean rust?

The fungus that causes soybean rust has many different host plants including soybeans, green beans, dry edible beans, sweet clover, and kudzu. Kudzu is an important host because it may play a role in where the fungus survives in North America. At this point we know that soybeans and kudzu can be severely diseased and support large amounts of reproduction by the fungus. The degree to which other hosts will become infected and allow reproduction remains unclear. It is likely that the varieties within a given crop will vary in their susceptibility to soybean rust.
