2018 Trial protocol
• GLP trials/ORETO standard
• Two winter wheat varieties: Skyfall and Leeds
• Three treatment regimes: – IPM – microbial seed treatment, conventional chemistry at high pest pressure, biopesticides at low pest pressure at standard
spray timings if needed
– Biological – microbioal seed treatment, biopesticides only at standard spay timings if needed
– Conventional chemistry – chemical seed treatment, conventional chemicals only at standard spray timings
– (no untreated)
• 6 replicates
• Randomised block design
• Three trial sites

Biologicals – a change in understanding contexts
soil ecology, plant ecology, landscape ecology, biology, microbiology,
genetics, microbial ecology, population biology, plant physiology, population
modelling, landscape modelling, population ecology, etc.………………
and maybe, sometimes, even chemistry
Biologicals – knowledge exchange
• Open days – at all three sites in 2017 and 2018
• Evening meeting in 2017
• Seminar – Great Yorkshire Show
• Website: www.crophealthnorth.co.uk
Education
Knowledge transfer to advisors, farmers, consumers, food suppliers, government, regulators:
• New technology – education/ costs/ value to business
• Understanding risks (or lack of risks?)
• New approach to crop protection – change resistance
Technology that can operate autonomouslyNext steps: integrating Biologicals with predictive diagnostics
