Scientists make progress in fighting wheat rust
Scientists have been hard at work in recent years combating a significant disease of wheat. Stem rust is caused by a group of nasty fungal organisms that can infect wheat plants and devastate yields. In some cases up to 100 percent of the crop can be lost.
The battle between stem rust and agricultural researchers isn’t new. Sometimes the tide runs in one direction, sometimes in another.
