Brown rot (monilia): how to spot, prevent and treat it disease
How do you spot brown rot (monilia)?
A brown rot spreading across the fruit, with light brown cushions of spores on it, often in concentric rings. The fruit drops or stays on the branch as a dried mummy.
How do you prevent brown rot (monilia)?
The fungus overwinters in mummified fruit and in cankered wounds in the bark, so collect and remove every rotten and mummified fruit and cut out affected twigs. The infection enters through a wound, so a net against birds takes away the main door. In a cluster it passes from one fruit to the fruit it touches.
What works against brown rot (monilia)?
For the home garden there are no fungicides against brown rot. What is left is picking off and removing the mummies as they appear and choosing less susceptible varieties.
