Pioneer winter oilseed rape hybrids
|
Our Pioneer winter oilseed rape hybrid range for the 2025 season includes:
PT303: The first winter oilseed rape hybrid to offer growers in the UK and Ireland top level yields with built-in tolerance to Sclerotinia.
PT312: Provides a very high gross output yield with a very high oil content combined with turnip yellows virus resistance and Sclerotinia tolerance.
PT315: This hybrid has given a high gross output yield with a very high oil content. It combines pod shatter resistance with turnip yellows virus resistance.
Pioneer winter oilseed rape seed is available treated with LumiGEN® Premium or LumiGEN Insecticide Premium powered by Lumiposa™. Both options include the nutrient growth promoter Lumidapt Optima™ and the fungicide Scenic Gold™.

|
|
|
PT303 Protector® Sclerotinia is the first hybrid offered to UK growers with a claim for Sclerotinia tolerance. Its impressive disease package includes TuYV resistance, partial resistance to verticillium stem stripe and a score of 7 for light leaf spot and 6 for phoma.
It’s proven its reliability with a gross output of 101% for the UK on the 2024 AHDB Recommended List, with 101% in the East West region and 100% in the North region. Additionally, with the strong yields achieved in years when cabbage stem flea beetle activity was very high across much of the UK, PT303 has further proven its ability to deliver. This season, choose the UK’s all-round top performer.

Proven herbicides for oilseed rape weed control
|
|
|
|
Our goal is to support farmers to maximise the potential of their oilseed rape crops by providing proven, reliable herbicides. Click on the links below to learn more about our crop protection solutions.
Belkar®: Post-emergence autumn herbicide for superior control of broad-leaved weeds especially cleavers, cranesbill, fumitory, poppies and shepherd's purse.
Astrokerb®: Powerful dual-action control that is exceptional against blackgrass and key broad-leaved weeds such as poppies and mayweed.
Kerb® Flo 500: Long-standing consistent control of blackgrass and other grass and broad-leaved weeds.
Korvetto®: Wide-spectrum spring applied herbicide. Highly effective on a range of problem broad-leaved weeds, with outstanding control of key weeds such as cleavers, mayweeds and thistles.

Stewardship steps to consider before drilling and at establishment of your oilseed rape
|
With harvest just around the corner and planning for the next crops underway, we thought it would be useful to remind growers about some of the stewardship best practices that should be considered now, ahead of OSR drilling. Field selection, tramline placement and buffer zones should all be considered with the objective of keeping the active ingredient out of watercourses.
Our new Propyzamide Knowledge Hub goes “back to basics” on what propyzamide is, how it works, how to apply it to achieve the best outcome, and practical advice on how to use it responsibly. Click here to visit our Propyzamide Knowledge Hub. You can also earn CPD points by testing your knowledge about propyzamide here. BASIS points: 3 (1 CP; 1 E; 1 AP) and 2 NRoSO points.

Give extra support to your oilseed rape crop by stabilising nitrogen in the Autumn
|
A crop reaching its yield potential is underpinned by successful establishment. In oilseed rape we have seen evidence of improved autumn establishment from using Instinct® in the autumn, especially when used in conjunction with slurry and digestate. Our internal development trials showed yield responses of up to 7% and improved spring vigour in oilseed rape when Instinct is used in the autumn.
|
|
Instinct can reduce leaching by around 50% and reduce denitrification through greenhouse gases by 45%. This means nitrogen is kept in the soil for longer and is therefore available for the oilseed rape to use.
The product should be applied at a rate of 1.7L/ha, as close to the application of the source of nitrogen as possible – ideally within a couple of days either side, if not applied with the slurry or digestate. Instinct can be applied to a seed bed and incorporated or simply sprayed on as a surface application.
