Pre-harvest fruit drop was markedly reduced over a period of 15 weeks by foliar sprays of 2, 4-D and 2, 4, 5-TP applied in November at a concentration of 20 p.p.m. An increase in the rate of fruit drop following a frost on 31 January, 1966, was much greater with untreated trees than with sprayed trees. Fruit from the treated trees were lower in soluble solids and higher in acid than those from the controls throughout the experiment.
