From 2001 onwards the MoA Classification Scheme included insecticides and acaricides but excluded nematicides, which are now addressed in a separate MoA Classification scheme. ⁵ Between 2005 ⁴⁸ and 2010 ⁵⁰ continued refinement of the MoA Classification Scheme led to the removal/reclassification of some Groups resulting in a reduction in the number of Groups.
