Abstract: | Chitosan-copper complex compared with chitosan alone enhanced suppression ofBotrytis cinerea rot development on four-true-leaf cucumber seedlings in controlled growth chambers. This paper constitutes the first report
of such enhancement. The optimal concentrations for the most effective suppression ofBotrytis development were 0.2 gl
−1 chitosan and 1.6 mmole copper. After 12 days’ incubation, marked and significantly better disease suppression was obtained
with chitosan-copper complex (75% suppression) than with chitosan alone. The chitosan-copper complex could be a very promising
decay control agent for use in both conventional and organic agriculture.
