Managing Fungal Leaf Spots on Tabebuia Trees

Fungicide Options for Tabebuia Leaf Spot Control

Black spots on tabebuia leaves indicate fungal leaf spot. Remove infected fallen leaves; avoid overhead irrigation. For valuable specimens, consider fungicide sprays: protectants (captan, chlorothalonil/Daconil, copper, mancozeb) or systemics (myclobutanil, thiophanate-methyl, propiconazole). Timing is critical—apply at bud break and repeat per label. Large trees require professional equipment. Bacteria leaf spots need copper-based products.
