About birch polypore
These keep showing up on the large birch log - third or perhaps fourth year. I made an adhesive bandage out of a strip of the pore layer and cut up two of the fruit bodies to use to make mushroom paper. Using my hand constantly, the bandage has remained in place for a couple of hours.
Symptoms to watch for
Treatment options
Fungicide Application
Apply systemic or contact fungicide at the first sign of infection. Repeat applications may be needed during wet weather. Follow label rates and timing.
Sanitation and Pruning
Remove and destroy all infected leaves, branches, and fallen debris. Improve air circulation by thinning dense canopy growth. Sterilize pruning tools.
Soil and Moisture Management
Ensure proper drainage, avoid overwatering, and apply mulch to reduce soil splash. Many fungal pathogens thrive in persistently wet conditions.
