Effect of BioSave(R) and carnauba wax on decay of cranberry.

An experiment was conducted on 15 October 1998 to determine the efficacy of the biological fungicides BioSave 110, BioSave 1000 (both containing Pseudomonas syringae), and carnauba wax on decay control of stored cranberries (Vaccinium macrocarpon). Fresh cranberries were sprayed with BioSave at 3 x 108 or 1 x 109 cfu/ml, and sprayed or not sprayed with carnauba wax. The cranberries were stored at 13 deg C. Disease development was recorded after 4, 8, and 16 weeks. Coating with carnauba wax consistently resulted in lower disease incidence than uncoated treatments. Coating with carnauba wax resulted in decay percentages of 17.1, 26.4 and 41.9% at 4, 8 and 16 weeks, respectively, compared with 20.7, 30.9 and 56.1% in the un-coated control. BioSave 110 reduced total decay during the 16 weeks. BioSave 1000 was effective only during the first 8 weeks. There was no significant difference between the application rates used. The best treatment, BioSave 110 with carnauba wax, reduced the total decay by 60

, 42 and 33%, after 4, 8, and 16 weeks, respectively.
