Experiments with moist heat treatments of 'Chandler' strawberries at temperatures ranging from 99° to 115° F for durations of 20 to 100 minutes showed that fruit heated up to 104° F for 30 minutes were still judged marginally marketable. Although some decay can apparently be controlled with heat, it is doubtful that fruit can tolerate the amount of heat required for insect quarantines.
