This is a disease that can be found on most turfgrasses, although zoysia may be the most severely affected. The rust develops orange or brown pustules on the leaves. If you get enough of these on a leaf, the plant’s ability to manufacture food is reduced and the turf thins out.
Asparagus spears are usually harvested before extensive rust symptoms appear. Symptoms are first noticeable on the growing shoots in early summer as light green, oval lesions, followed by tan blister spots and black, protruding blisters later in the season. Rust can infect many different kinds od plants. Treatment is the same for all.
