First, the withered leaves are become pale green in color, then brownish without the marginal portions of the leaflets. Do not use cut potatoes for propagation, since they can increase the incidence of the disease by up to 250%. Control root rot nematodes, because the wounds of the roots help the bacteria infect the crop. There is no treatment for the affected crop. The recent studies have highlighted some species of Pseudomonas fluorescens that appear to be very useful for biological control against Pseudomonas solanacearum.
