Joint Task Force on Environmental Indicators Geneva, July 2011Norwegian surveys on pesticide use in agricultureby Svein Homstvedt and Ole O. Moss, Statistics Norway

Contents

  • Our northern advantages
  • Pesticide use for field crops
  • Pesticide use for greenhouses
  • The “PPP-gap” (PPP = Plant Protection Products)
slide2
Survey on the use of pesticidesGeneva 2011A complex business, but fortunately there are some Northern advantages
  • Few crops
  • Less PPPs than further south
  • System of record-keeping on farm level has been implemented
  • More obedient farmers?
  • Some experience gained
survey on the use of pesticides field crops geneva 2011
Survey on the use of pesticides– field crops Geneva 2011

Comprising the following field-crops:

  • meadows and pasture land
  • grain (barley, oats, spring wheat, winter wheat, oil-seeds)
  • potatoes
  • onions, common cabbage, carrots
  • strawberries, apples

The population was covering 97 per cent of total agricultural area

Survey on the use of pesticides– field cropsGeneva 2011Content of questionnaires(8 versions)
  • Preprinted: area of a particular crop
  • Number of parcels (with the corresponding crop)
  • Equipment for spraying
  • Main type of PPP used on each parcel
  • Detailed use of pesticides on the largest parcel
    • number and date of treatments
    • size of area sprayed
    • name of compound
    • dosage per decare

Survey on the use of pesticides– field cropsGeneva 2011http://www.ssb.no/emner/10/04/10/rapp_200642/Survey design – field crops
  • Sampling frame:All holdings applying for governmental grants – except holdings practicing mainly organic framing
  • Sample size 2008: 4300 (9.5 % of frame)
  • Sampling plan considering:
    • 12 types of crops – then 8 questionnaires!
    • 4 size group by agricultural area in use
    • both “generalists” and “specialists”
    • an estimated “toxic load factor - TLF” for each crop(TLF = load of pesticid pr hectar specified for each crop x area of the specified crop)
survey on the use of pesticides field crops geneva 2011 data collection
Survey on the use of pesticides– field cropsGeneva 2011Data collection
  • 2001 and 2003: postal
  • 2005 and 2008: postal and web reporting
  • Questionnaires sent out in November
    • based on the number of holdings applying for grants pr. July
    • preliminary results in July the year afterwards
  • Voluntary response
    • Incentive: Lottery(3 traveller’s cheques of ca 1000 US$ each)
  • Response rate ca. 70 per cent (after one reminder)
  • Quality surprisingly good

    • 2005: 1 700 man-hours
    • 2008: 1 700 man-hours (ca)
  • 50 per cent financial support by The Norwegian Food Safety Authorities

Survey on the use of pesticides– greenhousesGeneva 2011 Comprising the following crop groups:
survey on the use of pesticides greenhouses geneva 2011 survey design greenhouse
Survey on the use of pesticides– greenhousesGeneva 2011 Survey design – greenhouse
  • Sampling frame:All holdings with a minimum of 300 m2 of greenhouse area
  • Sample size 2008: 685 (100%)
  • Sampling plan:
    • Ranking the nine crop groups by the number of holdings
    • Sampling all holdings in the crop group with the lowest number of holdings
    • Sampling all holdings in the next group, deducting those already sampled
    • Etc.
