| dc.description |
Five seedlots of Colorado blue spruce and three seedlots of Black Hills spruce
were sampled for Fusarium contamination. All seedlots contained some seed
and/or debris with Fusarium. Levels of contamination were greatly reduced by
treating seed with running water rinses for 48 hours or with chemical
sterilants such as sodium hypochlorite (bleach), hydrogen peroxide, captan, and
benanyl. All three species of Fusarium commonly isolated from seed, F.
oxysporum, F. solani, and F. tricinctum, were pathogenic to blue spruce
germlings after test tube inoculations. Reducing the amount of seed
contamination will help reduce future losses fran pre- and post-emergence
damping-off. |
