My name is Gav and I live in Sydney in a suburb called Rozelle. Rozelle is only 5 minutes from the CBD of Sydney. We bought the house we currently live in 3 years ago. The house is in a suburban street with a small front yard. There is a big tree in the front yard and around February of the first year we moved in it started producing huge fruits. I did some research and found out it was jackfruit. We had 30 Jackfruits in that first year. I am emailing to ask if I could ask you some questions about jackfruits. A lot of the jackfruits grow but the majority of them, when they are quite small, they start turning black and get a fur on them and fall off. I looked up on the internet what it might be and it seems to be called Rhizophus rot. I am wondering if you have ever heard of this and how you would treat it. I want to treat the fruit and look after it. Looking forward to hearing from you. Thank you. Gav.
I found several links that will help you with this fungus disease and treatment.
