Research was conducted to integrate preharvest disease control methods and postharvest practices to manage diseases, improve fruit quality, and extend the shelf-life of longans and rambutans exported from Hawaii. The main pathogens of longan and rambutans were isolated and identified as Lasmenia, Colletotrichum, Pestalotiopsis and Phomopsis. In vitro sensitivity of these pathogens to registered...

Broccoli (Brassica oleracea var. italica) is a vegetable that requires the application of postharvest techniques to extend its marketability. Controlled atmosphere and 1-MCP treatments are most used to extend the shelf life of broccoli and reduce post-harvest deterioration. The aim of this study was to evaluate the visual, physicochemical and functional changes of broccoli head samples stored a...

This presentation focuses primarily on recent developments in new technologies that have impacts on decay control. These technologies include 1-methylcyclopropene (1-MCP) and new preand postharvest fungicides. With the increasing use of 1-MCP in the apple industry, depending on varieties, many apples do not have to be drenched with diphenylamine (DPA) prior to storage. Because use of 1-MCP has ...

Laboratory studies were conducted to develop ultralow oxygen (ULO) treatment for controlling western flower thrips, Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae), on broccoli at a low temperature of 1 degree C. Complete control was achieved in 5 d at 0.003% oxygen. Oxygen level affected efficacy of ULO treatment. At a higher oxygen level of 0.03%, 6-d treatment killed -85% of ...

Considerable economic losses to harvested fruits are caused by postharvest fungal decay during transportation and storage, which can be significantly controlled by synthetic fungicides. However, considering public concern over pesticide residues in food and the environment, there is a need for safer alternatives for the control of postharvest decay to substitute synthetic fungicides. As the sec...

The modular design of plants enables individual plant organs to manifest autonomous functions and continue aspects of metabolism, such as respiration, even after separation from the parent plant. Therefore, we hypothesized that harvested vegetables and fruits may retain capacity to perceive and respond to external stimuli. For example, the fitness advantage of plant circadian clock function is ...

Pitaya is one of the most important commercial cactus fruit. Pitaya fruits are easy to get injury during postharvest handling and storage. Pre-harvest and postharvest calcium treatments have been used to maintain flesh firmness and extend shelf life of many fruits. The aim of this study was to evaluate the effects of calcium treatments on maintaining pitaya fruit quality during cold storage. Pi...
