Registration of Plant Protection Products in Japan

Plant protection products in Japan are regulated under the Agricultural Chemicals Regulation Act and approved if deemed safe in line with Good Agriculture Practice (GAP). Agrochemicals and biorationals are authorised strictly in aaccordance with their intended use, by specifying “application crop”, “application timing” and “application rate”. Farmers are only allowed to use plant protection products under the approved conditions of use.

Re-evaluation Programme

Until recently, agrochemicals in Japan were subject to re-registration every three years. However, the Agricultural Chemicals Regulation Act of December 1st, 2018 introduced a re-evaluation programme for active substances in the existing plant protection products available on the Japanese market.

The re-evaluation programme regulates the revision process by setting out clear timelines:

  • Plant protection products registered after enforcement of the amendment act require re-evaluation approximately every 15 years
  • Existing plant protection products are re-evaluated starting from 2021 according to a pre-defined priority order.
