Abstract

There are many treatments that have been used for postharvest diseases control in pineapple. An appropriate research need to be done to choose most effective treatment among all the treatments. This study was done to determine the most effective treatment to control postharvest diseases of pineapple. Treatments used were hot water dip treatment, waxing and fungicide application. Fruits were visualized to get to know whether the treatments influence their ripeness. The severity of diseases was determined through visualization by naked eyes and also detection of the presence of microbial colony. The presence of fungus and bacteria was determined from the colony that formed on PDA and NA media. Waxing was the most effective treatment to control post harvest diseases in pineapple compared to hot water dip and fungicide treatments. All treatments were very effective on the inner part of the fruits only but not on the shell part. Waxing not only controlled the diseases but it helped to delay ripening. More research about the control of post harvest diseases of pineapple should be done especially on waxing to better understand how they could control postharvest disesases in pineapple.
