The Effects of Keithia Blight on Outplanting Performance of Western Redcedar Container Seedlings at Two Reforestation Sites in British Columbia--Preliminary Results

The significance of various infection levels of Keithia blight on 2+0 container western redcedar seedlings after outplanting is examined. Increasing levels of Keithia infection had a negative effect on height and root collar diameter but did not impact survival. Site climate humidity appeared to contribute to the continued severity of the disease. Seedlings sprayed at the recommended nursery rate and timing with mancozeb were larger and had less disease.
