Research Project: EFFECT OF PRE-HARVEST SPRAYS OF CARNAUBA WAX & OTHER NATURAL TREATMENTS ON FRUIT TO PROTECT THEM FROM INFECTION & MAINTAIN QUALITY FOR SALES

Location: Citrus and Other Subtropical Products Research

Project Number: 6618-41430-005-02
Project Type: Nonfunded Cooperative Agreement

Start Date: Mar 06, 2009
End Date: Dec 19, 2013

Objective:
Study the effects of new technologies applied pre-harvest to protect fruit from disease and postharvest decay, including studies with citrus canker and other emerging diseases, on tropical and subtropical fruit.

Approach:
Initially we will test these natural compounds in the laboratory on fruit pieces in specially constructed containers. These compounds will be new for these applications in Florida. We will check for phytotoxicity, efficiency of combating disease under laboratory conditions and ease of use. This work will be conducted in the microbiology labs at the Citrus and Subtropical Products Research Laboratory, Winter Haven, Florida. Information from this preliminary work will be used to study these compounds pre-harvest on fruits in the field in collaboration with grower cooperators. From these field tests, we will be able to see the efficacy of using these natural coatings pre-harvest to keep fruit disease free and ready for packing, shipping and sale. For work with citrus canker we will determine if these compounds reduce inoculum and instance of canker, and open markets for shipment.
