Mucor rot - chemical control

• There are no fungicides effective against Mucor.
• Treatment of water with chlorine (calcium hypochlorite) has been used in the USA either alone or as a pre-wash prior to fungicide application, to reduce inoculum levels of Mucor present on fruit surfaces and in water in flotation tanks and hydro-coolers.
• Trials at East Malling have confirmed the effects of chlorine – see Penicillium rot.

Avoiding fungicide resistance

• No fungicides are effective against Mucor.
