How to spot it
The boll rot disease is a fungal disease on bush, pole, and fire beans, which mainly distorts the pods. Typical are dark brown to black, sharply bordered and sunken spots with a pale center, from which pinkish spore masses ooze when wet. Infected pods are unsellable, and the fungus moves into the seed, carrying it into the next year.
Prevention
You plant only healthy, certified seed and choose resistant varieties. Never enter the beds when wet, because spores travel from plant to plant via damp foliage. After harvest, remove all plant residues, do not compost them, and observe a three to four-year crop break for beans on the same plot.
