Abstract
Several natural compounds were evaluated for the control of Penicillium expansum on apples during green-ripe or ripe maturity stages and stored at ambient or cold temperature. Semipure or crude derivatives of Capsicum frutescens completely inhibited conidial germination of P. expansum at all concentrations. The crude derivative at 5.0 µg/L concentration reduced fruit infection. Overall, apples treated with chitosan at 1.0% had less infection at both maturity stages and storage temperatures. The extract of seed of yam bean stimulated disease incidence at both maturity stages and storage temperatures as compared to the remaining treatments. Hinokitiol was not effective in reducing fruit infection. During cold storage, the highest disease incidence was recorded after 8 week storage on apples treated with the C. frutescens derivatives, and after 16 weeks when treated with chitosan, hinokitiol, or the fungicide Mertec.
