Abstract
Blossom thinning and application of calcium influence storage life and apple fruit quality. Spray application of lime sulphur (4-5%) with olive oil (3%) and 0.05% synertrol oil as a surfactant at 75% bloom was most effective in reducing crop load with minimum leaf scorching and improved fruit quality in organically grown apple. Four spray applications of Biomin® calcium (3kg/ha) were highly effective in reducing bitter pit, scald and maintaining organic apple fruit quality.
