Pineapples

THE CHALLENGES OF TRANSPORTING PINEAPPLES

Pineapples are very susceptible to mold, especially on the crown or peduncle. Fungicides are typically used to control molds.

Exposure of pineapples to ethylene results in faster degreening of the shell.

Pineapples are chilling sensitive. Chilling injury appears as water- soaking of the flesh, darkening of the core, increased susceptibility to decay, and wilting and discoloration of crown leaves.

Shippers often use fungicidal treat- ments to control molds.

Mangos & Papayas

THE CHALLENGES OF TRANSPORTING MANGOS & PAPAYAS

Mangos and papayas are extremely valuable and sensitive commodities, and while in storage they are subject to Anthracnose and stem-end rot, as well as the detrimental efects of ethylene. In addition, because mangos and papayas are particularly susceptible to shriveling, humidity in storage must be kept high, which often leads to increased mold growth. Estimates for post-harvest losses run as high as 10–30% annually.

Grapes

THE CHALLENGES OF TRANSPORTING GRAPES

Grapes are very susceptible to decay, particular Botrytis cinea (gray mold).

Moisture loss affects grape appearance, especially rachis browning.

Shatter can occur during transportation and is exacerbated by ethylene.

Blueberries

THE CHALLENGES OF TRANSPORTING BLUEBERRIES

Blueberries are very susceptible to decay, particularly Botrytis cinerea (gray mold). In addition, temperature fluctuations resulting in condensation can accelerate mold growth and decay.

Blueberries are climacteric and respond to ethylene which accelerates aging.

Temperature management has a significant effect on blueberry market life.

Moisture loss affects blueberry appearance and texture, resulting in shriveling. Storage in high relative humidity alleviates this issue however it may lead to mold growth.

Avocados

THE CHALLENGES OF TRANSPORTING AVOCADOS

Avocados are sensitive to postharvest disease, particularly anthracnose (Colletotrichum gloesporioides) and stem end rots.

Ethylene causes ripening, softening, and internal discoloration. Soft fruit on arrival is a major issue in avocado transportation. Avocados are climacteric and sensitive to ethylene.

Avocados are sensitive to chilling injury and develop skin pitting and darkening, grey pulp, vascular browning, off odors and accelerated softening.

Citrus

THE CHALLENGES OF TRANSPORTING CITRUS

Citrus fruits are very susceptible to decay, particularly green mold (Penicillium digitatum) and blue mold (Penicillium italicum) which can easily spread from fruit-to-fruit. Traditional treatment includes fungicide application.
