What are the characteristics of grey mould?

• In most cases, airborne spores from the grey mould cause the infection.
• Spores enter the plant through a wound or senescent tissue.
• The disease develops and spreads rapidly under humid cloudy conditions and when temperatures are below 20°C.
• Grey mould also develops at refrigerated temperatures causing post-harvest damages.
