Pythium Root Rot
(fungus - Pythium sp.): This disease is most serious with young plants growing under conditions of high soil moisture and cool temperatures. Infected roots become water-soaked and flimsy [Picture]. Not all of the roots of the plant become infected [Picture]. The plants will not usually die, but severe infection can result in small bulbs. The loss of a substantial amount of roots will lead to tip dieback. Planting on raised beds will minimize the impact of this disease.
