Description
Summary:The biological agent strain B8 of Enterobacter aerogenes , applied in June Of 1992,1993,1994, and 1995 as a soil drench at 6.7 × 10 9 colony forming units per tree, was evaluated for control of Phytophthora lateralis root rot of Lawson cypress ( Chamaecyparis lawsoniana ) trees. The test was conducted under field conditions in the city of Vancouver, British Columbia, on naturally infected Lawson cypress trees. Based on four years of observations, strain B8 of E. aerogenes controlled the disease and increased the growth of trees. This study showed the potential of strain B8 of E. aerogenes for biological control of root rot of Lawson cypress trees.
