Mango fruit ripen unevenly (forum)

Rae starts with ...
I'm posting on my dad's behalf. He needs help with his mango tree. His first aussie mango harvest was beautiful (each fruit average @ 1kg) however he saw his mangoes ripening unevenly in subsequent harvests. The fruit's ripened at stem end but totally green at the tip. so by the time the tip ripens, the stem end's rotten. how to rectify this? can anyone help? many thanks!

Hello Rae
That is a fair lump of a Mango

I'm thinking a couple of problems. Anthracnose, but I doubt it. I think the fruit is being stung if it is actually ripening at the stem end. Our fruit fly usually stings nearer the tip.

Does the fruit also ripen around the seed first as well. Can you see any small white crubs near the stem when you cut the fruit. I would cut the seed open as well as that is where I think you will find the grubs

I don't know what you have there to spray the fruit with, a systemic spray perhaps to deter the critters and kill the larvae. Spray weekly from when the fruit has set properly

Cheers

Most australian mangoes(eg kensington) are subtropical and struggle even in the wet tropics of Australia.Thet too much humidity and rain and need cool weather for flower initiation.Anthracnose is just one problem.Better to grow the excellent Thai types in equatorial and wet tropical places.

I think a lot of Queensland farmers will dissagree with you there Mike. The QLD Mango industry was first established in Bowen over 100 years ago who have provided the Mango varieties in the link plus many more, except for the Honey Gold [a Bundaberg/Childers variety]

You should have noticed the orchids west and south of Cairns that are mostly Kensignton and R2E2 now

Fair enough inland and elevated at Mareeba and Mitchilba where rainfall is less than 1000mm and frost is possible R2E2,kensington,the florida and californian ones do better than the humid (2000-4500mm) wet tropics lowlands. A kensington plantation would be better suited to the sunshine coast than the Tully to Daintree lowlands.
Dry tropics south of Ingham down to Briz would still be better I reckon.Calypso is also from down there.Nowher in Malaysia is anywhere near as cool and dry as Bowen and 'Bowens' from Bowen are way better than those from Daintree or Cairns.
