Mango Leaf Problems (forum)

Justin starts with ...
Can anyone identify the problems in my young (2 years in the ground) mangoes?

1. New growth is pale (almost white) with a few blemishes. Normally the new growth is red.
2. Leaves are breaking down from the mid-ribs.

This is occurring on 2 different mangoes, but in the same area. First problem is with R2E2 seedling. Second is with a grafted Royal Red. Posting together as they may be related.

Thanks.

Re the mango problems . Try spraying several times with zinc sulphate at 1.5 to 2 grams per litre and 3 grams /litre Epsom salts and 2 grams/itre of urea to make it stick .. I use 2 tablespoons of each in my knapsack that is 16 litre to fill line .. It saved my citrus and improved mango out of sight .. If u have a marginal zinc problem and marginal magnesium problem do not use phosphorus until u improve zinc availability . And I have given multiple sprays of this mix in a day and a few times a week . Suggest u try it first and see how it goes . No dramatic results but see improvements over weeks . U can use on curcubits too. Zinc spray works on lack lustre plants and urea is to help I stick . read internet about zinc and try it . Also lack lustre passionfruit like this brew and apply as u see fit .
as a footnote if u suspect a zinc problem spray 1gram/litre mix and urea is also used .Lack lustre plants respond

Thanks for that, I will definitely try it. I did wonder about zinc deficiency and applied some trace elements around the root zone and watered in. The R2E2 has responded well, the Royal Red not at all. My other suspect is anthracnose. But I'll try the zinc for awhile and see what happens.
