Likewise, will anthracnose kill trees? In general, anthracnose diseases do not kill trees, but repeated infections can weaken trees to other problems. Some defoliation may occur, but refoliation with healthy leaves follows in warmer weather. Concentrate on boosting tree vitality, which promotes new growth.
Also asked, what fungicide is used for anthracnose?
The most effective fungicides for control are the protective fungicide chlorothalonil (e.g., Ortho Max Garden Disease Control), copper sprays (e.g. Bordeaux mixture), propiconazole (e.g. Banner Maxx), and the systemic fungicide thiophanate-methyl (e.g., Cleary's 3336, which is available for professional use only).
What does anthracnose look like?
