Other claims from this paper (9)
- Intervention effect Protected Populus trees of most clones were over 2 m taller after three seasons.
- Intervention effect Protected trees had diameters over 1–4 cm larger.
- Intervention effect Insecticide protection increased above-ground volume by over 20 dm 3 in one clone.
- Intervention effect Insecticide protection increased above-ground volume by at least 4 dm 3 in all other clones.
- Intervention effect Beetle defoliation caused a 50–73% loss of above-ground volume.
- Observation Defoliation impact differed among clones.
- Intervention effect The Populus deltoides clone 91 × 04‐03 showed the greatest growth response to chemical protection.
- Intervention effect Clone NM2 responded least to chemical protection.
- Recommendation The authors recommend chemical and cultural control to reduce herbivore impacts until resistant clones and natural enemies are better understood.
