Technical Abstract: The first report of Verticillium wilt in peanut was from Asia in 1937. The disease was reported in Australia in 1945 and in the United States (New Mexico) in 1985. It occurs in other peanut-growing countries, and although yield reductions of 60% have been reported in Argentina, it is not considered a serious worldwide production constraint. Verticillium wilt of peanut is found in all peanut-producing areas of the United States and has increased since 1970, but the disease is of economic importance only in New Mexico and Oklahoma. The occurrence of Verticillium wilt in Oklahoma in 1994 was widespread and severe in some fields. Data on yield losses in peanut in the United States caused by Verticillium wilt are not yet available.
