Reading about Lucerne as a living mulch, I had heard about issues with Verticillium in Lucerne when monocropped, particularly in the second year, is this soil type related or is the pressure somewhat allievated when its grown intercropped?
We grow lucerne as a forage crop for 5 years in the same place and have not had an issue. I think it comes in with the seed. Some varieties more resistant than others?
We wont go back to lucerne for 5 years in rotation.
