How can I identify potato plants affected by brown rot and bacterial wilt?
The symptoms of potato brown rot and bacterial wilt can vary, but there are some common signs to look out for. Infected plants may show wilting, yellowing, or browning of leaves. The tubers may develop a dark brown rot that is often accompanied by a foul odor.
