Effect of Ethephon, Diphenylamine, and Daminozide on the Incidence of Scald Development on ‘Cortland’ Apples1

Year: 1977

Type: article

Abstract: Preharvest sprays of (2-chlorethyl)phosphonic acid (ethephon) and succinic acid-2,2-dimethylhydrazide (daminozide) and postharvest dips of diphenylamine (DPA) were evaluated for their effects on scald development of ‘Cortland’ apples ( Malus domestica Bork.) The total number of scalded fruit and the severity of scald were increased in all years by ethephon treatments. Daminozide treatments reduced scald incidence and severity either alone or in combination with ethephon. DPA dips (2000 ppm) resulted in best scald control. It is postulated that advanced ripeness of the fruit due to ethephon contributed to increased scald incidence.
