| The effects
of preharvest sprays of 1% calcium nitrate, 0.1% Topsin-M
[thiophanate-methyl], 0.1% Bayleton [triadimefon] and their combinations
on the storage quality of fruits of E. officinalis [Phyllanthus emblica
] cv. NA-6 were investigated. Treatment with 1% calcium nitrate + 0.1%
Topsin-M was the best followed by 1% calcium nitrate + 0.1% Bayleton
and 1% calcium nitrate. The lowest weight loss (11.09%) and decay loss
(14.43%) were observed in fruits given 2 pre-harvest sprays of 1%
calcium nitrate + 0.1% Topsin-M, this treatment prolonged shelf-life to
up to 20 days compared with 10 days in the control at ambient
temperature. Calcium nitrate-treated fruits had higher concentrations
of Ca than control fruits. Treatment with Topsin-M and Bayleton
controlled Penicillium oxalicum for 10 days and Aspergillus niger for
20 days and extended shelf life. |
