New CRD Efficacy Crop Guide: Potato

Date: 5 June 2019

The new guide on the “Interpretation of efficacy data requirements for the authorisation of a plant protection product in potato (SOLTU) in the UK” helps applicants in interpreting current efficacy data requirements and relevant EPPO standards. It also provides information on UK agronomy, relevant UK targets and trial numbers, if seeking for a UK-only authorisation of outdoor applied products in potato. Post-harvest treatments are not covered.
The document contains UK specific details on potato production, such as information concerning planting and harvesting timings and crop rotation. Furthermore, it provides valuable information regarding the potato market, planted areas and varieties in the UK. Very useful is also the detailed description of major and minor UK pests (insects, nematodes, slugs), diseases and weeds, the number of required trials and extrapolation principles.
