Abstract

ythium ultimum--Washington (State), Eastern. Chickpea--Diseases and pests--Washington (State), Eastern. Damping-off diseases--Washington (State), Eastern.
Legumes and large-seeded (Kabuli-type) chickpeas are highly vulnerable to Pythium damping-off when planted in cold, wet soil in the spring due to their thin seed coat and amount of fluid released during germination. Seed treatments including metalaxyl have been the silver bullet for protecting chickpea seed from Pythium damping-off. Recently in some notable cases, metalaxyl has been losing its effectiveness because Pythium species in Palouse soils are developing resistance to it.
