Classroom Module 1 (half day) – The principals of safe pesticide residue management
- EU legislation
- Worldwide legislation
- Derivation of MRLs
- ADI/ARfD/Toxicology vs Consumption
- Breakdown characteristics Koc, Kdr and impact of temperature and light on breakdown
- Metabolic pathways to activity, i.e. basic chemistry of how key fungicides work and where to find this information
- Plant structures and why residues are different in roots/fruit compared to leaves (in the same crop).
- Analytical procedures, with examples of how tests work for key pesticides e.g. OP’s and azoxystrobin and boscalid
- Quality control
- Field sampling
- Pack house sampling.
Introduction to pesticide legislation:
Classroom Module 2 (half day) – Optimising pesticide use for practical growing
- How to design a testing programme fit for purpose, and what are the costs involved.
- Case studies from industry. Examples of typical pesticides in use and their ‘watch outs', notably when they have long tails and why? E.g. Mancozeb, triazoles, azoxystrobin, boscalid, pyrethroids, OP insecticides.
- How agronomy protocols can be dictated by end customers and impacts on residues.
- How to look at pesticide use from POV of minimising pesticide residues, e.g. time of the season for application, dose rate decline curves and their dependences, application techniques, resistance development.
- How to design a process that flags and manages pesticide residue issues, e.g. call out when 50% MRL and how to call out and develop corrective action for MRL exceedances.
- Review of PRiF reports on crops, e.g. Roots, Lettuce and Kale.
- Consumer risk assessment:
- Link to food safety
- Using modelling tools to assess consumer impact of residues
