Pear trellis rust is a new disease for Connecticut in 2012. It is caused by the rust fungus Gymnosporangium sabinae. The disease is common in Europe and has been present in parts of Canada (British Columbia) since the 1960s and the Pacific Northwest since the late 1990s. It was reported in Ontario in 2007 and in Michigan for the first time in 2009. In 2011, pear trellis rust was confirmed in southeastern New York state. The disease is capable of causing losses in pear crops and impacting the health of ornamental pear trees.  Read more here>>>
