Brendon starts with ... Hi all, I have a mango tree that was planted last year. There are a few people with mango trees around this area planted in similar locations (Wollongong, NSW) and I have seen a fair bit of fruit on a number of them also so really wanted to get one. However the tree I planted a year ago has not grown at all (No new leaves or shoots). The old leaves have some kind of disease. However it did recently start to flower. The problem is the small leaves that are growing in the flower sections are all dying. I am not sure what is wrong with this tree and how to treat it. I recently sprayed with a copper spray as we have had leaf curl on other trees. You can see the rust-like spots on some of the larger leaves in the picture (it is on most of the leaves to some extent this is one of the worst that I took a photo of). Also where the flowers are it looks like there is a kind of sap. Any ideas what the problem is with this tree? If more pictures would be helpful please let me know. I have attached one of the flower (where you can the dying small leaf shoots), one of a larger leaf that exhibits the rust, and one of the tree as a whole. Thanks, Brendon.

David_WM says... Brendon, Mangoes don't really like winter in the southern areas. Overall the tree doesn't look too bad. I'd give it a spray with mangozeb / copper oxychloride like mentioned in the other thread that Denise mentioned. Let it set fruit and when the fruitlets are pea sized, cut off all the flowering panicles and then you should get a good flush of foliage. Sometimes if you cut off the flowers the tree just flowers again. Letting it set fruit seems to stop the urge to flower again. A light dose of flowers & fruit fertiliser is a good practice coming into the warmer season. It does not look like it is undernourished, so don't overdo the fertiliser. Strange that it didn't flush last year, maybe you got it just after the flush and it took the rest of the season settling in. | About the Author DavidWM1 Perth 3rd October 2012 1:31am #UserID: 7278 Posts: 30 View All DavidWM1's Edible Fruit Trees |

Brendon Costa says... Thanks for the information. I did have a look at that other enormous thread on mango disease. I didn't think any comments in that thread exactly matched what I was seeing (some were similar but I wanted to get an opinion from the pictures of the foliage). I have already sprayed with copper oxychloride as per the other thread. I might do so again soon as the packaging suggests multiple sprays. That advice sounds good. I will follow it and see if we can get a flush of foliage this year. Thanks, Brendon. | About the Author Brendon Costa Wollongong, NSW 10th October 2012 3:10pm #UserID: 7285 Posts: 4 View All Brendon Costa's Edible Fruit Trees |

dep1993 says... Brendon, it appears that I have the same issue as you do. I think it might be "Bacterial Leaf Scorch" I found what seems to be a good description in this link I provided in the bottom related to the symptoms displayed. My hypothesis is that if it is bacteria, perhaps it would be induced by the foliage getting wet to often. I could be wrong. https://plantdiseasehandbook.tamu.edu/food-crops/nut-crops/pecan/ | About the Author dep1993 Marble Falls, Texas 12th August 2019 3:43am #UserID: 20695 Posts: 1 View All dep1993's Edible Fruit Trees |
