Monsanto Exagon: Field Performance and Observations

When selecting a winter oilseed rape variety, predictability is just as important as peak yield. The Monsanto Exagon variety has proven to be a reliable workhorse in our fields. As a population variety, it offers great flexibility, allowing us to manage our seed inventory without the annual overhead associated with high-cost hybrids. It is a straightforward, productive cultivar that doesn't require complex management to perform.

Disease Resistance and Crop Protection

The main challenge in our region is managing phoma and alternaria, especially in humid seasons. Exagon demonstrates solid natural resistance, which significantly reduces the pressure on our fungicide program. We have also seen excellent performance against sclerotinia and downy mildew, meaning we spend less on emergency chemical applications and more on routine maintenance. Its resistance to bacteriosis further stabilizes the crop development, ensuring a uniform stand heading into the winter.

Yield Potential and Economic Value

The oil content of 45–50% is a major selling point. The low erucic acid and glucosinolate levels (16–17 mmol) meet strict market requirements, ensuring our grain is always in demand at premium prices. In terms of yield, we consistently hit the 50–60 c/ha range, with our average performance landing around 55 c/ha. For a population variety, this is an impressive ROI, especially when combined with a reasonable nitrogen fertilization strategy.

Key Takeaways for Farm Management:

• Robust population type that reduces long-term seed costs.
• Built-in resistance to major pathogens like Phoma and Alternaria.
• High-quality grain metrics that facilitate easier contracting with processors.
• Consistent performance across varying field conditions.

Managing the Exagon variety is a simple process for the farm team. It is not overly sensitive to minor fluctuations in agronomic practices and responds well to standard management. If you are looking for a reliable, high-yielding winter rape variety that won't let you down in an average growing season, Exagon remains our top choice.
