A combination of control measures to reduce damage from “yellows” disease of sugar beets has resulted in yield increases of 42 per cent in the overwintering area of central California. The yield increases were made possible through earlier planting with suppression of sugar beet yellows through the use of a resistant variety, and aphid control.
