 ===== Description =====
-Phyllosticta Leaf Spot is an aggressive fungal disease caused by the pathogen *Phyllosticta*. It is characterized by rapid progression, presenting as distinct fungal lesions or black spots on the epidermis of infected cacti. If left unchecked, it poses a significant threat to the infected plant and can quickly spread to surrounding collections.
+Phyllosticta Leaf Spot is an aggressive fungal disease caused by the pathogen *Phyllosticta*. Forms light brown to tan lesions with no particular orientation or pattern. Often the lesions are boarded by a darker brown line and pycnidia fruiting bodies are uniformly distributed. Lesion can generally grow larger than either Phoma or Phomopsis, easily confused with both. If left unchecked, it poses a significant threat to the infected plant and can quickly spread to surrounding collections.
-===== History & Origin =====
-The disease is a known pathogen within cactus collections. A notable documented case occurred in June 2026 when grower Mel Moe sought assistance for an aggressive infection, which was subsequently diagnosed by community expert Gee Bee.
 ===== Cultivation Notes =====

 * **Fungicide Protocol:** Apply systemic and contact fungicides. Alternate applications of thiophanate-methyl and azoxystrobin, or use Mancozeb, to prevent the pathogen from developing resistance.
 * **Substrate Optimization:** Verify that the media pH is within the appropriate range for Trichocereus and ensure the soil has excellent drainage.
-* **Nutritional Support:** Supplement the fertilizer regimen with additional calcium, magnesium (calmag), and potassium to bolster the plant's natural immune defenses.

Alternate apps. Isolate if it is spreading. Improve drainage and and consider adding a tad more calmag and potassium to your routine." |
