    Abstract : The influence of five nursery field management treatments (soil cultivation, oxadiazon application, Lotus corniculatus companion crop, winter rye + Lolium perenne + Festuca rubra cover crop) on the incidence of stem cankers caused by Nectria cinnabarina on Gleditsia triacanthos var. inermis cv. Skyline was monitored in Minnesota. Although considered a stress related disease, field management treatments that reduced tree vigour decreased susceptibility to attack by N. cinnabarina while treatments which promoted vigorous growth increased susceptibility. The observed vulnerability of G. triacanthos trees to N. cinnabarina may be related to plant cold hardiness and subsequent winter injury to root and crown tissue as affected by nursery field management treatment. Moisture stress late in the growing season, resulting from root injury during the previous winter, mechanical root injury from cultivation, and high summer soil temperatures may have increased susceptibility to N. cinnabarina in G. triacanthos grown in bare soil field production systems. Moisture stress in late summer may not be reflected in plant growth, but may increase the susceptibility of G. triacanthos trees to attack by N. cinnabarina.
