Viburnum Leaf Beetle (Pyrrhalta viburni) control http://www.durgan.org/URL/?XKTMT 17 September 2009 Viburnum Leaf Beetle (Pyrrhalta viburni) control This pest devastated my European snowball (Viburnum) bushes in the Spring of 2009. Originally from Europe and Asia, established breeding populations were first recorded in 1978 in the Ottawa-Hull area. Attempting to preempt an attack in 2010 spraying with a mixture of lime sulfur and horticulture oil was commenced. This is about the only commercial insecticide in my arsenal. Pictures depict the procedure undertaken. Does it work? Spring of 2010 will be the time for evaluation.
