[Effect of environment on the teleutospore viability of Ustilago coicis].
The teleutospores of Ustilago coicis can retain their germinating power under indoor dry conditions for about five years. They can survive the winter in the fields in Beijing. Increase of soil humidity could reduce the number of teleutospores in soil. Rotation is an efficient method to control the head smut of Jobs-tears and the rotation cycle is two years minimum.
