Abstract:

New plant spray oils were applied in schedules of 1, 2, or 3 applications before and/or after bloom. There were more applications, as well as later applications, than required in normal pest-control programs. The response of apple trees was measured by counting the blooming buds and fruit on 500 spurs on each single tree plot. Covariance analysis of fruit on bloom revealed no significant difference for any source of variation resulting from treatments. It was concluded that the Superior oils would not reduce the number of fruit during the season of use or the number of blossoms set for the following year.
