Biology and control of Fusarium spp. on Douglas-fir (Pseudotsuga menziesii)

Creator:

Hoefnagels, Mariëlle Henriette, 1965-

Abstract:

Fusarium spp. are among the most important pathogens of Douglas-fir (Pseudotsuga menziesii) seedlings in bareroot nurseries. Currently the most effective disease control method is soil fumigation with methyl bromide. As methyl bromide is phased out, however, other disease management strategies may become more important. We explored two alternative approaches to...

Tree vigor and the susceptibility of Douglas-fir to armillaria root disease

Creator:

Rosso, Pablo H.

Abstract:

The main objective of this thesis was to determine the influence of tree vigor on susceptibility to Armillaria root disease. First, the effect of thinning, fertilizing and pruning on tree vigor of four young Douglas-fir (Pseudo tsuga menziesii var. menziesi,) plantations was explored. Tree vigor was calculated by measuring wood...
