Abstract

In contrast to results of previous years, May-planted beets became 44% infected with yellows and did not yield as well as March and April plantings in 1963 tests at Davis. Three sprays, for aphid control, applied to May-planted beets, increased production 9.5 tons of roots per acre, 5.3 more tons of roots per acre than beets planted in March.
