In blind seed disease, unfertilized or developing seed of susceptible grasses are colonized by the fungus Gloeotinia temulenta. Infection results in loss of seed germination. About 56 species of grasses are susceptible, including important forage and turf grasses such as ryegrass and tall fescue. The disease occurs in all areas of production of cool season grasses grown for seed.
