Key messages Winter oilseed rape provides a major benefit to UK agriculture Major benefit to farmers’ rotations Gross margin, spreads fixed costs and provides weed control Alternatives will result in loss of profitability Spring crops already viewed as less profitable and unacceptable options Farmers and agronomists must act now to ensure this valuable crop is still available Adopt best practice and participate in stewardship Protect water from herbicides and other pesticides

Oilseed rape active substances at risk Revision of 91/414/EEC Annex 1 listingWFD – chemical WFD - ecological cyproconazole prochloraz carbetamide napropamide propachlor quinmerac tau fluvalinate zeta- cypermethrin metaldehyde carbetamide clopyralid glyphosate metaldehyde metazachlor propyzamide carbendazim cyproconazole flusilazole glufosinate metconazole tebuconazole carbendazim chlorothalonil chlorpyriphos insecticides Home Back to map

Impacts on farming Weed and pest control Rotations Margins Home Back to map
26
Key losses 1 – black-grass control WFD – propyzamide, carbetamide, metazachlor Vital for control of black-grass 40% rape area affected Major impact on yield (36% yield loss) Equivalent to 280,000t loss production Home Back to map
27
Loss of black-grass control Key implications OSR yields could be reduced by up to 1.2t/ha Up to £390/ha in lost gross margin – 75% Yield loss from competition, increased herbicide costs Few alternative crops on heavy land Rotational implications are even bigger Additional cost in wheat - £300/ha More ploughing, delayed sowing, yield loss, increased herbicide costs Spread of work load and early entry for cereals lost NB where black-grass is a problem Home Back to map
28
Secondary Loss – up to £300/ha from winter cereal margins Two hits are greater than one! Primary Loss – up to £390/ha from current OSR margins NB where black-grass is a problem Home Back to map
29
Key losses 2 - slugs WFD & Annex 1 listing – Metaldehyde Already under scrutiny Complete crop losses a possibility if lost Typically 3.5% yield loss Replacements (methiocarb) available – environmental & cost implications Home Back to map
30
Loss of slug control Average yields could be reduced by up to 0.2t/ha Up to £60/ha in lost gross margin – 15% Alternative methods are more expensive Home Back to map
31
Other areas of concern Revision of 91/414/EEC – metconazole & tebuconazole Used as PGRs as well as fungicides Can provide additional 0.2 t/ha yield response in absence of disease. On individual crops this could cause losses of £60/ha Home Back to map
32
Alternative crops Heavy land suited to winter cropping Winter field beans Spring cropping Fallow Home Back to map
33
Rotational implications Main break crop in arable rotations In black-grass areas provides cleaning crop If black-grass herbicides lost & control reduced; Less favourable in black-grass infested fields Alternative break crops (beans, spring cropping or fallow) may be sought Increase in amount of ploughing to bury weed seeds Home Back to map

Carbon Emissions Emissions from; Production of raw materials (fertilisers, pesticides, seed) Fuel usage in transport of raw materials & final product Fuel usage in tractors & other farm operations Soils as a result of nitrogen application & residue incorporation From disposal of waste (plastics & packaging) Home Back to map
45
Carbon impacts of OSR production Large amounts of N applied High emissions involved in production of N N 2 O released as a result of application Nitrogen approximately = 50% of total emissions Home Back to map

Summary – winter oilseed rape has a… Farming Major benefit to farmers rotations Gross margin, spreads fixed costs and provides weed control Trade Positive effects on UK balance of payments Significant requirement for N and crop protection Environment Good crop cover in autumn to reduce nutrient leaching and soil erosion risks Value to birds by providing feed and nest sites Home Back to map
