A. alternata is the main postharvest pathogen of mangoes in Israel. The pathogen penetrates the fruit through lenticels during fruit growth and remains quiescent until harvest. During fruit ripening after harvest, the pathogen begins to develop, and black spots appear on the fruits resulting in reduced marketability. No preharvest treatments are applied in Israel to prevent postharvest diseases. Postharvest treatments are applied according to the climatic conditions in the area of the mango orchard. Fruits from orchards located in dry regions, where postharvest disease is low, are only water washed. However, fruits from orchards located in humid regions, where disease incidence is high, are treated with 900 micro g prochloraz/ml. A simple postharvest treatment was developed which involved a hot water spray at 50-60 deg C while the fruits were brushed. In several mango cultivars stored for 3 weeks at 14 deg , this hot water brush treatment reduced decay caused by A. alternaria to levels similar t
o those attained using prochloraz. When fruits were stored for longer periods of time, prochloraz was more effective than the hot water brush. The possible use of this treatment in the postharvest mango industry is discussed.
