Abstract

Formulations of superior oil applied to the developing buds and bark of ‘Delicious’ apple trees in the greenhouse inhibited bud break and growth. Bud break was significantly affected by oil concn, viscosity, and unsulfonated residue (UR). Total fresh wt of shoots was adversely affected by increasing concn and decreasing UR. Severity of bark injury increased with decreasing viscosities and increasing concn.
