BIOLOGICAL CONTROL OF POSTHARVEST DISEASES BY COMBINING A SUGAR ANALOG WITH AN ANTAGONISTIC YEAST
Patent Number: 5591429
Docket Number: 11393
Serial Number: 8095552
Date Patented: 01/07/1997
Agency:
Agricultural Research Service
Issued:
December 7, 1996
Abstract:
The invention relates to post harvest preservation of fruit using a sugar analog (2-deoxy-D-glucose) and
an antagonistic microorganism (Candida saitoana). Synthetic fungicides are often relied upon to
control post harvest disease, but these are expensive and cause concerns over the health risk of such
chemicals. The inventors have discovered that C. saitoana and a sugar analog are effective in
controlling grey mold rot (Botrytis cinerea) in apples, blue mold or green mold on citrus fruit.
Harvested fruit is treated by dipping or spraying.
