MARCH 2026 UPDATE - PIONEER® WOSR LINE-UP FOR 2026:
For 2026, the Pioneer winter oilseed rape portfolio is built around four proven hybrids and an exciting new expanded hybrid range. Each hybrid provides a distinct combination of yield potential, disease resilience and oil content to suit a wide range of UK and Ireland growing conditions.
- PT303: PT303 is the UK’s first hybrid to combine Protector® Sclerotinia tolerance with partial resistance to Verticillium stem stripe. With strong autumn vigour and TuYV resistance, it is designed to support reliable establishment and consistent performance where high late season disease pressure is a key concern.
- PT312: PT312 delivers very high gross output potential with a high oil content. It combines Protector Sclerotinia tolerance, pod shatter tolerance, turnip yellows virus resistance and partial resistance to Verticillium stem stripe. PT312 gives the grower a strong all‑round package that targets both yield and oil bonus opportunities.
- PT315: PT315 offers a robust agronomic profile with pod shatter resistance, TuYV resistance and high oil content. With excellent autumn vigour and a consistent output, PT315 provides a dependable option across a range of UK and Ireland drilling and harvest conditions.
- PT322: NEW for 2026! PT322 has a high gross output yield with a very high oil content – the highest in the Pioneer range. It combines Protector Sclerotinia Tolerance with turnip yellows virus resistance and is pod shatter tolerant. PT322 scores an 8 for stem canker resistance due to its combination of broad background genetic resistance and specific LmS genetic resistance.
The 2026 Pioneer WOSR portfolio delivers a clear choice of reliable, high‑performing hybrids to suit diverse UK growing conditions. With proven genetics and a strong new addition, it offers confidence for the season ahead.

FEBRUARY 2026 UPDATE:
Oilseed rape crops going into the winter were looking good with large canopies and good crop cover. However, following the cold spell and snow in mid‑January, crops have opened up in places.
As spring approaches, with more exposed soils and on-going pigeon pressure, there is increased potential for further weed germination.
Autumn conditions were generally favourable and crops are likely to have received a good autumn herbicide programme for both broad‑leaved and grass weeds. Even so, it’s still important to assess weed levels and plan spring treatments where required. With continued canopy opening, warmer temperatures and high moisture levels, spring weed flushes are likely.
It’s important to take a programmed approach to weed control and a spring application is part of that. Korvetto is a simple, reliable spring herbicide for winter oilseed rape, combining two proven actives to deliver strong, fast control of key broad‑leaved weeds. It is easy to use, gentle on the crop, and fits well into typical spring workloads.
Key benefits include:
- Wide‑spectrum control of the weeds that matter most, including cleavers, mayweeds, cranesbill, thistles, fumitory and poppies.
- Two actives working together for more consistent results and support for resistance management.
- Performs well in typical spring conditions, from cool mornings to warmer days.
- Ideal for tidying up fields in the spring, especially where autumn treatments didn’t go to plan.
- Korvetto® mixes well with a large range of products, especially those required for canopy management or crop nutrition.
- Korvetto is the most broad-spectrum option, with two active ingredients – Arylex™ active and Clopyralid.
