Sunscald has been appearing in some fields in many areas. Sunscald occurs when plants are ripening during periods of heat or other stresses. The main symptom is purpling on the stems and pods. The purpling is an abiotic stress response and does not cause yield loss. The purpling is likely due to higher levels of anthocyanin pigment and a lack of chlorophyll in the naturally senescing tissue and often shows up more in some varieties than others. Confirm sunscald by checking the underside of the pods or branches (areas not exposed to the sun) for normal pod colour.
