Other claims from this paper (5)
- Intervention effect Precommercial thinning reduced cumulative pitch canker incidence to 64% versus 90–98% in other treatments.
- Intervention effect Thinning alone reduced cumulative pitch canker severity by 43%.
- Observation Positive thinning effects on disease occurrence and severity were most evident during severe outbreaks.
- Intervention effect Potassium plus micronutrients combined with thinning increased disease incidence by 50% relative to thinning alone.
- Mechanism The authors suggest silvicultural effects may involve physiologically active defense mechanisms, but the mechanism is unclear.
