| Post-harvest control of Botrytis in roses | |
| Commercial application of Methyl jasmonate (MJ) as a useful and environmentally friendly post-harvest control method for suppressing Botrytis cinerea in cut roses. A practical application of MJ consisting of simultaneous pulsing and spraying, was developed for growers handling conditions. Experiments determined that the optimal treatment was pulsing with 350 µM MJ and spraying with 500 µM MJ. This combined MJ treatment neither increased ethylene production in petals, nor it was phytotoxic. This MJ treatment effectively suppressed the development of Botrytis cinerea following both natural and artificial infection in a range of rose varieties. In yellow, orange and pink cultivars, the MJ treatment improved petal color by inhibiting color fading during vase life. S. Meir, S. Droby, B. Kochanek, S. Salim, S. Philosoph-Hadas.
