摘要

From 1975 to 1980, nearly 1,200 ha of hybrid poplars were planted in central lower Michigan for fiber packaging material. A study was undertaken to: (1) assess the impact of Septoria on the affected plantations and to determine if the trees could be carried to full rotation, (2) determine if disease severity of susceptible clones could be minimized by planting mixtures of clones with differing resistance to S. musiva, and (3) determine if pruning and sanitation could reduce disease severity within plantations.
