Wattle%20affected%20by%20fusarium%20wilt

We face a few challenges on our bush block - acidic clay hard pan soil, gum trees, and voracious wallabies. But our arch enemy is fusarium wilt.

This is a wattle tree we suspect is affected by fusarium wilt (Fusarium oxysporum), which is a fungal disease. You can see the rings of dark brown where the disease has entered the branch.
