Oilseed rape is an integral part of the UK arable rotation, but it’s not without its risks and challenges. Corteva is committed to supporting farmers and agronomists to grow oilseed rape successfully.
This online hub will support you through the season. Bookmark this page and visit regularly for updates.
Stewardship considerations ahead of drilling:
As preparations for drilling begin, now is the ideal time to think about stewardship alongside crop establishment and weed control. The decisions made before and after drilling can play an important role in protecting water quality while ensuring effective crop protection throughout the autumn and winter.
When planning your oilseed rape crop, consider factors such as soil type, topography, cultivation strategy and direction of travel during establishment. These can all influence the risk of product movement and should form part of your stewardship planning.
Good stewardship starts with good planning. Taking a proactive approach now can help protect local watercourses and support the sustainable use of crop protection products.
We have a range of useful online resources that provide key stewardship information, including guidance for both before drilling and at crop establishment - check them out 👇

JUNE 2026 UPDATE - Pioneer® winter oilseed rape hybrids:
At Corteva, we offer a portfolio of high-performing Pioneer® WOSR hybrids, proven in UK and Ireland conditions and designed to deliver consistent yield, strong agronomics and valuable disease protection.
- PT303 – the first winter oilseed rape hybrid to offer growers top-level yields with built-in tolerance to Protector® Sclerotinia and partial resistance to Verticillium Stem Stripe, helping reduce the impact of key stem-based diseases.
- PT312 – delivers excellent gross output and very high oil content, combining Protector Sclerotinia tolerance with partial Verticillium Stem Stripe resistance and pod shatter tolerance for added harvest security.
- PT315 – a reliable, high-performing hybrid with very high oil content and pod shatter resistance, offering strong establishment and consistent performance across a range of conditions.
- NEW: PT322 – combines high gross output with exceptionally high oil content and strong disease defence, including Protector Sclerotinia tolerance, Turnip Yellows Virus resistance (TuYV) and enhanced stem canker resistance through LmS genetics.
Every Pioneer hybrid offers resistance to TuYV, supporting crop health and safeguarding yield potential.
Pioneer WOSR seed is available treated with LumiGEN® Premium or LumiGEN Premium Insecticide Powered by Lumiposa™. Both options include:
- Scenic Gold™ fungicide for early disease protection
- Lumidapt Optima™ nutrient growth promoter to support early vigour and establishment
The addition of Lumiposa provides seed-applied insecticide protection that enhances crop establishment, reduces early feeding damage and supports plant vigour. It is particularly valuable where early-season pest pressure, such as cabbage stem flea beetle or cabbage root fly, may threaten establishment.
Together, Pioneer genetics and LumiGEN seed treatments help establish healthy, uniform crops with the potential to maximise productivity.

Thank you for taking part in our 2026 OSR Survey!
A big thank you to everyone who completed our recent Oilseed Rape Survey.
The survey attracted responses from farmers, agronomists and applicators across a range of farming regions, providing an interesting snapshot of current and future OSR growing intentions, herbicide use and weed control experiences.
Many responses (nearly 90%) indicated that they intend to continue growing OSR next season, while others highlighted plans to maintain or increase their OSR area where conditions allow. Responses also reinforced the important role that effective weed control programmes continue to play in supporting successful OSR establishment and crop performance.
Corteva herbicides such as Astrokerb®, Belkar®, Kerb Flo 500®, Korvetto® and LaDiva® were all mentioned by respondents, with over 80% of respondents sharing positive experiences relating to weed control and programme performance. Over three-quarters of respondents reported using at least one Corteva OSR herbicide.
The survey also generated a wealth of practical feedback around challenges faced by growers, including changing seasonal conditions, difficult application windows and weed pressures. These insights help us to better understand the priorities of growers and advisers and will inform future technical content and communications.
Congratulations to Andrew Melton, who was selected at random as the winner of our luxury food and drink hamper, worth over £150!
