Securing supplies of different sources of active substance technical materials for manufacture of Plant Protection Products can help agrochemical companies safeguard their production and supply. If supply issues were experienced with a technical material sourced from one manufacturing location, having alternative sources can help ensure an adequate supply to maintain PPP production.

It was wonderful to see so many of our clients, collaborators and friends at SETAC Europe in Copenhagen last month. For many of us it was the first chance in 2 years to get together in person. We hope you enjoyed it as much as we did!

There was a great spread of interesting scientific topics. One significant scientific advancement we noticed was the proliferation of TKTD modelling talks and posters beyond its usual home in the effects modelling session. This approach is starting to establish itself as a “go to” method for the future – a progression our ecotoxicologist Dr Alice Tagliati contributed too with two posters on the application of the approach in regulatory risk assessment.

Earlier this month saw the first new PPP active substance approval granted in Great Britain under the retained Regulation (EC) No 1107/2009.

The herbicidal active substance, cinmethylin, supported for approval by BASF plc, was formally approved in Great Britain on 7^th June 2022 following the Health and Safety Executive’s (HSE) risk assessment of the substance and conclusion that it is expected to meet the criteria for approval.

We have received a number of queries recently relating to the use of UK efficacy trials in support of EU product registrations post Brexit. The question arises due to the UK no longer being an EU member state, and therefore no longer participating in the EU plant protection product registration programme under EU regulation 1107/2009.

Well, you can rest assured - The UK is still geographically part of Europe, and as such remains included in the maritime zone under EPPOs ‘zones of comparable climate’ as described in EPPO guidance PP 1/241 – Guidance on comparable climates.
