Pea : Pea wilt
(revision date: 6/3/2014)

Pea wilt is caused by a fungus. Several races of the fungus occur and may cause different symptoms. Typically, plants are yellow, stunted, wilted, and often die. Plants affected by races 1, 5, and 6 may show downward curling of leaves and stipules. Stems are more rigid and brittle than uninfected plants. These plants may also show a yellowish to orange discoloration inside the lower stem and the root system. The root system otherwise appears normal. Race 2 causes a disease known as "near wilt". The general symptoms are similar to those described. In addition, foliage may show a grayish discoloration and the disease may result in yellowing and wilt of the plant. The internal discoloration caused by Race 2 is typically dark red. The root system of affected plants may show some decay.
