Dwarf Butter Beans Wilt

Question

Each year I plant my dwarf butter beans in my plot they begin to wither at the time just before flowering. . . . I usually lose more than 50% of my plants and get hardly any crop. . . other crop plants in the plot seem unaffected during their growth cycle.

Answer 1

It sounds like they may have Fusarium Wilt. The ones that are not affected may be in uninfected beds. This article will explain more about it:
