hornbeam trouble

Trouble has started already!! the new leaves on one tree in my forest are turning blackand the buds on one of the single trees are doing the same...the book says spray with systematic fugunicide sp ?? what is the best to use???? THANK YOU Take care john

Hi John
I have battle some fungus here in Australia the last couple of years and it does sound similar to what happens with some of my hornbeams.
I found Bravo worked real well on Tridents and Kocide Blue extra worked well on the hornbeams. Frequent spraying is essential as I understand they both work as a protect ant. So it will stop it spreading to the new growth.
Don't defoliate as I found that the tree needed the strength to fight even from the damaged leaves. Defoliating killed the tree in some cases. Ever heard don't defoliate an un-healthy tree

Picture will be good.

Hi Moyogijohn

I use ready to spray Rosespray for fungiside, from the compagny " bayer"

Kind regards Yvonne

Thank you Yvonne,,,I will get the same thing today..i have to control this problem... REST TAKE CARE JOHN

Thank you also Brent..try to get this done take care john

It may be a bacterial infection. I use lime sulfur spray diluted as per the label (about 30:1). Try not to water the foliage when you water your trees.

Hi Moyogijohn

I do take care, the yamadoriseason is ower.

Jimlewis could very vell be right.

Kind regards Yvonne

brett i am sorry i misspelled your name last night...thanks for the tip not to cut the leaves...Yvonne i got the rose spray and started with it...Jim lewis i sprayed the trees and put them on the porch to control the water i will not spray the foliage when watering....thank you all take care john

Are you sure it's an infection? My Korean hornbeam is very sensitive to sunburn in the spring.
