Growing Variety
• Medium-Rapid Autumn growth habit – suitable for drilling into 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 autumn if at all.
• 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.
• Pod Shatter Resistance reduces the risk of seed losses approaching and during harvest and will protect the crop where harvest is delayed
• Ensure the Green Area Index is accurately determined at the start of spring growth to guide appropriate nitrogen rates for optimal canopy size. Lodging risk with DK EXSTAR is low.
• Light Leaf Spot should be monitored but strong resistance reduces the risk of severe infections.
