Distribution details in Poland
Pest status declared by NPPO: Absent, pest no longer present (2014-10)
From CABI Disease map 041 (2009): Absent, pest no longer present
In 2013, Italy intercepted infected maize seeds from Poland. Investigations showed that these seeds originated from a Polish operator who had imported sweet corn seeds (cv. Golden Bantam) in 2007 from France and then reproduced them on his own farm in order to sell them for the production of sprouts. Following the interception by Italy, all infected maize seeds were used for animal feed and the production field was placed under quarantine. All other maize seed lots produced by the farm concerned were tested and all results were negative. The NPPO of Poland considers that this incidental finding will not lead to establishment, stressing that the main disease vector, Chaetocnema pulicaria, does not occur in Poland and that the climatic conditions are unsuitable for the disease (NPPO, 2013).
From January 2012 until June 2014, 201 maize seed samples were collected across the country and tested. All results were negative. Based on these negative results, the unsuitable climatic conditions for the bacterium prevailing in Poland, the absence of the main insect vector (Chaetocnema pulicaria), the NPPO concluded that the bacterium does not occur in Poland (NPPO, 2014).
