Wheat Rust Pustule

Wheat rust is caused by a parasitic fungus and can affect both the leaves and stems of wheat plants. In individual fields, the disease accounts for crop losses ranging from trace amounts to as much as 40 percent when weather conditions are favorable for fungus growth. Rust infections usually appear as yellow, orange, red, rust, brown, or black powdery pustules on leaves, young shoots, and fruits.
