 For the years as of 2000, the specified maximum HCB concentrations in chlorothalonil differ considerably from pesticide to pesticide – in some cases despite the EU-regulation, the values differ from year to year for the same pesticide. For the year 2000 an interim value was calulated by linear interpolation. (170 mg/kg).  For the years as of 2000, the specified maximum HCB concentrations in chlorothalonil differ considerably from pesticide to pesticide – in some cases despite the EU-regulation, the values differ from year to year for the same pesticide.

-According to information from the BVL (October 2020, personal communication), the maximum content of HCB in chlorothalonil was increased from 10 to 40 mg/kg in the products "AMISTAR Opti" and "CREDO" due to subsequently applied for active substance sources.  Likewise, an additional potential active substance source (production site) was also reported retroactively. For the years 2001 to 2017, the value of 40 mg/kg (for the reporting 2022) is used for the maximum content of HCB.+According to information from the BVL (October 2021, personal communication), the maximum content of HCB in chlorothalonil was increased from 10 to 40 mg/kg in the products "AMISTAR Opti" and "CREDO" due to subsequently applied for active substance sources.  Likewise, an additional potential active substance source (production site) was also reported retroactively.

 For the years from 2018 onwards, the information from the authorisation holders (Syngenta Agro, 2015) is used for the maximum concentration of 10 mg/kg, as only the product “AMISTAR Opti” was still on the market. For the years from 2018 onwards, the information from the authorisation holders (Syngenta Agro, 2015) is used for the maximum concentration of 10 mg/kg, as only the product “AMISTAR Opti” was still on the market.

 The following chart give an overview of the emission trend of HCB (see Picture 1). HCB emissions were fully recalculated up to 1990. HCB emissions are mainly dominated by the share of chlorothalonil. According to the BVL (2021a), a possible explanation for the increase in HCB emissions from 2005 onwards would be the re-approval of "Bravo 500" in December 2004 against Septoria in wheat and then for the first time against Phytophthora in potatoes. The following chart give an overview of the emission trend of HCB (see Picture 1).

 It is possible that the first "sell-out" took place in 2014, as the end of approval for "Bravo 500" was originally 30.04.2016 with a sales deadline of 30.10.2016 and a phase-out period for users until 30.10.2017. It is possible that the first "sell-out" took place in 2014, as the end of approval for "Bravo 500" was originally 30.04.2016 with a sales deadline of 30.10.2016 and a phase-out period for users until 30.10.2017.
-The end of the EU active substance authorisation for chlorothalonil was later extended to 31.10.2018 and again to 31.10.2019, and with it the authorisations for the plant protection products in Germany. With the Implementing Regulation (EU) 2019/677 23), the BVL revoked the last three approvals for plant protection products containing chlorothalonil on 31 October 2019. A sell-off period until 30 April 2020 applied((cf. BVL; 2021c: https://www.bvl.bund.de/SharedDocs/Fachmeldungen/04_pflanzenschutzmittel/2019/2019_06_19_Fa_Widerruf_Chlorthalonil.html)). Often, in the last years before the end of the approval, the remaining stocks are brought onto the market, which leads to higher sales than in previous years.+The end of the EU active substance authorisation for chlorothalonil was later extended to 31.10.2018 and again to 31.10.2019, and with it the authorisations for the plant protection products in Germany.
