Postsowing applications of the fungicide dicloran (Botran) caused stem injury to young blue spruce (Picea pungens Engelm.) seedlings in a Colorado forest nursery greenhouse. Initial symptoms for some of the affected seedlings included stunting, stem swelling, and twisting. Seedlings without conspicuous symptoms appeared to develop normally until later in the growing season, when they fell over or they became brittle and broke when handled during packing and shipping.
