DK Exsteel THE RECOMMENDED ALL-ROUNDER DK Exsteel is DEKALB's latest EX variety with podshatter and double phoma resistance

•Rapid Autumn growth habit – suitable for drilling up to mid 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 but high resistance reduces the risk of severe infections.
•The rapid autumn growth habit means a PGR may be required in early/mid October on crops early sown or on fertile sites to reduce the risk of over development pre winter.
•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 Exsteel is low but there may be a benefit from PGR use to optimise the canopy structure.
•Pod Shatter Resistance reduces the risk of seed losses approaching and during harvest and will protect the crop where harvest is delayed.
