Wheat stripe rust is one of several diseases that affect only wheat. It is caused by a fungus and is a problem in cool climates. Stripe rust appears as yellow powdery pustules in stripes parallel to the veins in the leaf. Outside the wheat-growing season, wheat stripe rust survives on plants such as barley grass and later blows onto growing wheat crops, infecting the young seedlings. Control measures include sowing resistant varieties and using fungicides.
