http://www.durgan.org/URL/?Potatobug 15 June 2009 Colorado potato beetle (Leptinotarsa decemlineata) The ubiquitous potato bug appeared today. I found four adults and no eggs. Method of control is picking them off the vegetation,, since I have only about 70 plants. If the potato field is large chemical control is almost mandatory. http://www.durgan.org/URL/?FAKES Summary:P Potatoes 2009.
