Deskripsi
Leaf-crumple, a virus disease of cotton—first observed about 1948 in the Coachella Valley—has been found in the Imperial, Borrego, Mexicali, and Yuma valleys and in the Gila Valley up to a point well east of the town of Roll, Arizona. However, neither the leaf-crumple virus nor its insect vector has been seen in the San Joaquin Valley.
