Single‐bath hot‐water treatment for the control of loose smut (Ustilago nuda) in cereals

SUMMARY The single‐bath hot‐water treatments for the control of loose smut in wheat and barley give satisfactory results over a range of time/temperature combinations. Thus the soaking period recommended for wheat ranges from 1 1/2–2 hr. at 120°F. (49°C.) to 5–6 hr. at 105°F. (41°C): for barley the range is from 1 1/2 hr. at 120 to 5 hr. at 105°F. The general relationship in these treatments may be expressed as t=k logh+c, where t= temperature, h= minimum no. of hours required and k and c are constants.
