An effective and potentially commercial reduction of cracking in sweet cherries is reported from experiments conducted on 5 sites over 3 seasons. The treatment, Cu(OH)2 at 200 g per 100 litres plus Ca(OH)2 at 3 kg per 100 litres applied at 3 and 6 weeks after full bloom, resulted in a significant and consistent reduction in the proportion of cracked fruits from susceptible cultivars after moderate crack-inducing rainfall.
