Abstract
Cotton yields have progressively decreased in many fields in Tulare and Kings counties in the San Joaquin Valley since 1960. Losses have been attributed to new races of Verticillium albo-atrum, potassium deficiency, and a change in tolerance to Verticillium wilt in the Acala 4-42 variety (grown exclusively in the San Joaquin Valley since 1954 because of its wilt-resistance).
