Technical Abstract: It is often difficult to extrapolate information obtained under laboratory conditions to the field. This is especially true in the case of translating reactions between microorganisms grown in a Petri dish with experimental antimicrobials, and using these experimental compounds in commercial applications. Often large volumes of fruit or other natural materials (e.g. leaf or wood tissues) are used for a virtually untested protocol and result in a large expenditure of time and materials. An intermediate method, where experimental compounds could be tested on a specific commodity without expending large quantities of either fruit or experimental compound, would be practical and economical. A method such as this was developed at the Citrus and Subtropical Product Labs in Winter Haven, and employs the use of a small experimental chamber in which pieces of natural materials (e.g. fruit) are tested with experimental compounds. These results are more analogous to what happens in the field than the laboratory dish.
