Abstract
Combination treatments with radiation at 200 or 750 Gy and hot water (53.degree. C) or hot 0.1% a.i. imazalil (53.degree. C)for 3 min were more effective than single treatments for control of anthracnose and stem-end rot of Tommy Atkins mangos [Mangifera indica] caused by Colletotrichum gloeosporioides and Diplodia natalensis or Phomopsis citri, respectively. Irradiation at 750 Gy inhibited development of ripe skin color and caused some browning and pitting of the skin. Effects of radiation on skin color and injury were partially offset when heat treatment preceded irradiation. Individual wrapping of mangos in shrink film resulted in increased decay and breakdown.
