 This observation led the ICPBR to designate this sowing practice as “poor farming practice” and to therefore encourage the rapid implementation of measures designed to solve this dust problem on a European level.Before the investigation of the incident was complete, the BVL suspended the authorization of eight seed treatment products on corn and canola.Upon completion of its investigation, the German Federal Ministry of Food, Agriculture and Consumer Protection “banned for a period of 6 months the planting of maize by means of negative pressure pneumatic machines for single grain delivery; this ban applies to maize seeds treated with clothianidin or with one of three further insecticides.” Germany reauthorized the use of clothianidin as a seed treatment on canola in June 2008 after the Julius Kühn Institute submitted its findings that equipment and sticker problems associated with corn seed treatments in Germany are not applicable to canola.
