Zusammenfassung: | The efficacy of the combination of Burkholderia cepacia
B23 with 0.75% chitosan and 3% calcium chloride
(CaCl2) as a biocontrol treatment of anthracnose disease
of papaya caused by Colletotrichum gloeosporioides, was
evaluated during storage. The growth of B. cepacia B23
in papaya wounds and on fruit surfaces was not affected
in presence of chitosan and CaCl2 or combination
throughout the storage period. The combination of B.
cepacia B23 with chitosan-CaCl2 was more effective in
controlling the disease than either B. cepacia B23 or
chitosan or other combination treatments both in
inoculated and naturally infected fruits. Combining B.
cepacia B23 with chitosan-CaCl2 gave the complete
control of anthracnose infection in artificially inoculated
fruits stored at 14 oC and 95% RH for 18 days, which
was similar to that obtained with fungicide benocide®.
Moreover, this combination offered a greater control by
reducing 99% disease severity in naturally infected
fruits at the end of 14 days storage at 14 oC and 95% RH
and six days post ripening at 28±2oC, which was superior
to that found with benocide® or other treatments tested.
Thus, postharvest application of B. cepacia B23 with
chitosan-CaCl2 as enhancers represents a promising
alternative to synthetic fungicides for the control of
anthracnose in papaya during storage. KCI Citation Count: 4 |
