Seed Treatment - White Mold Management Practices

Seed treatments can prevent the spread of white mold inoculum in infected seed. This is particularly important for seed harvested from fields where white mold has been severe. Traditionally it has been thought that transmission can only occur if sclerotia are found mixed with the seed. Illinois researchers have found that seedborne mycelium, present without obvious symptoms of infection can be present in a significant percentage of seed harvested from infected fields. Treatment with commonly available seed treatment fingicides will eliminate the problem. Transmission of white mold by sclerotia can be a problem if seed has not been properly cleaned during conditioning. This is especially true for seed produced by the grower in his own fields.
