@Arcadium, one year at the farm I did a lot of lactic acid bacteria foliar sprays and that seemed to work as I had zero rot all season. I commented on that once and an answer back was to just use a dilute milk solution which will have enough LAB to outcompete the mould. I still haven’t tried that but I might this year. My Overdose is being slow and the strain write-up from Divine suggests rot can be a problem. I’ll have to go buy some milk.
Hydrogen peroxide is a maybe in that it’s easy to overdo and cause real damage. Dilute milk sounds much more benign.
Mostly airflow is key prevention and is always better than a cure.
