IRAC International held their 46^th meeting in the CropLife International offices in Brussels on 28^th – 31^st March 2011. This was our biggest ever meeting with 46 participants, including visitors from the European resistance action groups as well as IRAC representatives from around the world. The meeting consisted of a mixture of concurrent IRAC working group sessions, a meeting of the Executive Committee and an International review day. There was an excellent exchange of information with around 40 presentations made during the course of the 4 days. The existing elected officers, including Ralf Nauen as the IRAC Chairman were unanimously re-elected for a further year.
