Common smut is caused by two fungi; Tilletia tritici and Tilletia laevis. Because it requires cool moist soil conditions, the disease is less of a problem on spring planted wheat than winter wheat. Common smut reduces wheat yields and grain quality. Wheat contaminated with bunt spores has a pungent, fishy odor and a darkened appearance.

Sandstorms -- also called duststorms -- are caused by strong winds blowing over loose soil or sand, and picking up so much of that material that visibility is greatly reduced. The widespread abundance of loose sand in deserts makes them the most common locations for sandstorms to form. In desert regions at certain times of the year, sandstorms become more frequent because the strong heating of the air over the desert causes the lower atmosphere to become unstable. This instability mixes strong winds in the middle troposphere downward to the surface, producing stronger winds at the surface.
