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
