Abstract

For the third consecutive year, sprays for aphid control applied to sugar beets planted at Davis, decreased yellows virus infection and substantially increased root production. Three sprays applied to beets planted in March, April or May, 1964, resulted in yield increases of 6, 9 and 5 tons per acre respectively.
