Growing Variety
• Medium-Rapid Autumn growth habit – suitable for drilling up to early September
• Seed rate should target an even plant stand of 25-30 plants/m2 in spring
• Double phoma resistance means phoma leaf spot thresholds for treatment may not be met until later in the autumn if at all.
• Light Leaf Spot should be monitored and treated as required.
• The medium-rapid autumn growth habit means a PGR may be required in early/mid October on very forward crops to reduce the risk of over development pre winter.
• The fast spring growth habit means PGRs should be considered on forward crops and fertile sites or those with a history of lodging along with appropriate nitrogen rates to avoid oversize canopies. Ensure the Green Area Index is accurately determined at the start of spring growth.
• Pod Shatter Resistance reduces the risk of seed losses approaching and during harvest and will protect the crop where harvest is delayed
Breeders view
“DK Exception selected as a Recommended List candidate for the East/West Region. It has given outstanding gross output over a wide range of UK and European locations. It features pod shatter resistance, double phoma resistance and very high lodging resistance. Initial work suggests that it has improved Nitrogen Use Efficiency (NUE).”
