What do you guys think about this fungus? It’s not tip blight. The tip of the foliage is still green, not dark green but very soft. The end of the branch turned brown and died. I think 80% of the tree is dead even though i treated it with copper fungicide twice, mancozeb once and hydrogen peroxide twice for root drench. Seem like it’s a Cercospora fungus but I’m not 100% sure.
