Transcript

  • 1. Broom’s Barn Research Centre Farming Futures meeting Climate change Mike May Broom’s Barn Research Centre
  • 2. Agenda • Welcome – Clare Wyatt & Mike May • Climate change - Mike May - introduction - Eric Ober – water use - Mark Stevens – crop protection • Farm Walk • Summing up discussion with coffee • 16.45 finish Broom’s Barn Research Centre
  • 3. Climate change • Range of changes include • Drier and warmer(?) summers • Wetter winters • More extreme weather events (wind, rain, temperature • These affect most aspects of farming – e.g. cropping/land use, agronomy, rotations, energy, biodiversity. Broom’s Barn Research Centre
  • 4. Broom’s Barn Research Centre
  • 5. Broom’s Barn Research Centre
  • 6. Crop Protection under a changing climate Dr Mark Stevens Broom’s Barn Research Centre
  • 7. Effects of climate change (1) • Increased pest / disease survival • Changes in predator survival • Synchrony between pest & predator • Increase diseases in spring • More generations of pests per season. Broom’s Barn Research Centre
  • 8. Effects of climate change (2) • See more warm climate diseases/pests • Earlier incidence of current pests/diseases • Faster crop & weed growth • Increased risk of root rots • Harvest in wetter autumns? • Storage under warmer conditions? Broom’s Barn Research Centre
  • 9. Warmer springs & summers (1) • More generations of Beet Cyst Nematodes • Multiplication/season increases • Actions - Increase rotation length / avoid host crops - Consider trap crops in summer?
  • 10. Warmer springs & summers (2) Silver Y moth • Overwinter nearer UK • Actions - Greater vigilance - Treat if threshold reached - Action across host crops. Broom’s Barn Research Centre
  • 11. Warmer springs & summers (3) Red spider mite • Likes hot weather (>25°C) • Actions - Able to consider varietal tolerance. Broom’s Barn Research Centre
  • 12. Warmer springs & summers (5) Rhizomania
  • 13. Distribution of rhizomania in Europe 1952 Italy 1971 Yugoslavia 1972 Greece 1973 France 1974 Germany 1978 Czechoslovakia 1979 Austria 1979 Romania 1982 Hungary 1983 Switzerland 1983 Bulgaria 1983 Netherlands 1984 Belgium 1987 UK 1988 Spain 1997 Sweden 2000 Denmark 2002 Poland 1950 1960 1970 1980 1990 2000
  • 14. Climate change on rhizomania • Warmer springs & summers • Rhizomania inoculum levels in soils increase • Need to:- - Use tolerant varieties on infected or high risk fields (build up less on tolerant varieties) - Maintain adequate rotation - Control weed beet Broom’s Barn Research Centre
  • 15. Peach-potato aphid (Myzus persicae) Broom’s Barn Research Centre
  • 16. Warmer wetter winters (1) • Increased aphid survival • Increase in virus levels • Actions - Use seed treatments (new ones better persistence) - Ensure good hygiene (e.g. cleaner loader clamps, set- aside). Broom’s Barn Research Centre
  • 17. Comparison of predicted incidence of virus yellows with actual in East: 1965-2005 Percent crops infected with virus yellows 100 With pest management Without pest management 80 60 40 20 0 1965 1970 1975 1980 1985 1990 1995 2000 2005 Year
  • 18. Myzus persicae at Rothamsted 1965 - 2007 (2007 is shown in red) First suction trap record July r 2 = 0.793 June P < 0.001 May April -1 0 1 2 3 4 5 6 7 Jan - Feb mean screen temperature °C Broom’s Barn Research Centre Richard Harrington RRES
  • 19. Total numbers of Myzus persicae caught in 3500 water traps 2003 2004 2005 2006 2007 3000 Number of M. persicae 2500 2000 1500 1000 500 0 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 May June July Aug Week number Broom’s Barn Research Centre
  • 20. Virus Yellows - effects on yield Beet yellows virus Early June infection 50 40 Yield decrease (%) Beet mild yellowing virus 30 20 10 Beet chlorosis virus 0 BYV BMYV BChV
  • 21. Warmer springs & winters • Further actions - Seed treatments work - BUT need to protect them - Stewardship across crops - Rotate insecticides in rotation (e.g. potatoes, brassicas) - Reduce infection by good hygiene. Broom’s Barn Research Centre
