Are you struggling with Silver Birch Tree problems in Australia? If you’ve noticed black spots forming on leaves, early leaf-fall or complete summer defoliation, the culprit may well be Birch Leaf Spot (Marssonina betulae). This fungal disease affects European birch species in Australia — especially Betula pendula ("Silver Birch") and cultivars like “Dalecarlica” and “Youngii”.
The fungus overwinters in buds and twigs, then spreads via wind-borne spores in spring. Early symptoms: small black spots that gradually merge into necrotic tissue; untreated trees can be severely defoliated, weakening them over successive seasons and inviting insect pests or secondary diseases.
We are seeking:
Plant pathologists or arborists experienced with birch and fungal control
Suppliers of effective fungicides, micro-injection treatments, or systemic disease control
Landowners with afflicted trees who want help diagnosing or treating
We offer:
Payment or equipment exchange
Collaboration for field trials & documentation
Networking opportunities in horticulture / arboriculture
Contact us if you can help rescue, treat, or prevent birch leaf spot in Australia’s silver birch populations.
