verticulum Wilt

[rhawes]

one of my japanese maple jubilee and it is a graft seems to have Wilt when should I use reliant systemic fungicide on it? should I wait until next year before it buds or use it more diluted on the whole tree? the instructions are a little confusing on what to do for maples please help anyone who has experience using this product!

Pictures would be useful : J. maples are prone to fugal diseases, some of them not very harmful (leaf spots), other more worrying but that can be controlled and cured (Pseudomonas), but verticilium is a killer.

Without more info, it's hard to give you an answer. No treatment will cure verticilium wilt. If it's verticilium wilt, there only one solution : burn it, and make sure all the trees around are quarantined. Most other fungal infections on maples can be cured with a copper-based product.

the leaves ends dried up and curled since I was afraid it would spread I cut off the dried ends now I have no idea what it could be and it seems to be growing leaves very slowly this spring any ideas? Maybe bacterial leaf scorch?

This can be a benign symptom that may have nothing to do with verticillum, fungal deseases, or nasty rotting attacks : once again, post photos, that would help a lot.

Sunscorch, overwatering, etc (then watch the soil mix), etc.

this particular maple had the same problem last year so it makes me think it is some sort of disease?
