Other Names:Also referred to as Covered Smut of wheat.
Description:Dark brown masses or balls of powdery spores replace the Wheat grains. These balls may force the glumes apart making them easier to see but they are often quite difficult to see in the head. With time the spores blow away leaving the naked stalk and a few glumes.
Biology:Requires cool (5-150C) and moist conditions for infection.
Life Cycle:Spores released from ruptured Bunt balls contaminate grain and soil. Under cool (5-150C) moist condition at planting the first leaf of the crop seedling is infected. The fungus develops and grows through the plant to the head where new Bunt balls are produced as the crop matures.
Origin and History:Distribution:
Management and Control:Sow crops early when temperatures are greater than 150C.
Thresholds:Very difficult to detect in the field. Zero tolerance levels for export grain.
