The share of live crown lost to fungal leaf blight, which hits blue gum hardest in its juvenile foliage during the wet establishment years before the canopy transitions to more resistant adult leaves.
Mycosphaerella and Teratosphaeria leaf blights routinely strip 10–30% of juvenile blue gum crowns in wetter years; sustained heavy defoliation can cut rotation volume materially.
DPIRD WA ↗Because photosynthesis lives in the crown, defoliation translates almost directly into lost height and volume. Tracking it through the susceptible early years tells you whether a genetic or chemical intervention is warranted before growth is permanently pegged back.
Silo pulls each of these from the sources the operation already uses, and keeps the figure current automatically.
Plant families selected for leaf-blight tolerance on high-risk sites.
Favour wider spacing and airflow to shorten leaf-wetness periods.
Monitor juvenile crowns through wet springs to time any response.
