Abstract

Sugar yields from sugar beets planted at Davis on May 2 last year averaged 50 to 90 per cent higher than yields from plantings made in March. The date of planting study linked the yield differences with unusually heavy aphid flights resulting in high levels of infection by a complex of viruses in the early planted beets. By mid-May, aphid flights had dropped to low levels and the later planted beets were relatively free of viruses.
