Evaluation Of Fungicides For Control Of Botrytis Blight Of Container-Grown Redwood Seedlings

Botrytis blight caused by Botrytis cinerea (Fr.) Pers., is a common and damaging disease of container-grown coast redwood, Sequoia sempervirens (D. Don) Endl. The disease also can be severe in field-grown redwood, giant sequoia, Sequoiadendron giganteum (Lindl.) Buchholz, Douglas-fir, Pseudotsuga menziesii (Mirb.) Franco, and other tree seedlings (1). Benomyl provided excellent control of the disease (2) but this fungicide is no longer effective in many locations because tolerant forms of the fungus have developed. However, there are other contact fungicides that will provide protection and that are useful in controlling the disease on other crop plants. This trial was designed to test the efficacy of these fungicides in controlling the disease on redwood seedlings.
