病害

基質
Leaf rust of poplars, causing severe leaf damage and early defoliation on susceptible species and clones. Continued defoliation of successive flushes of growth predisposes trees to winter injury and dieback and can cause death of trees, especially nursery stock and trees 1-2 yr old. Reduction in incremental growth of timber occurs with susceptible varieties. Some damage can occur to the conifer hosts. It is often severe on Pseudotsuga menziesii and in nurseries Pinus spp. and Larix spp. can be heavily attacked [1]
