PT303 Protector® Sclerotinia tops the 2022 AHDB UK Recommended List Pioneer's NEW Winter Oilseed Rape hybrid with tolerance to Sclerotinia is launched with the top position for yield in AHDB RL Candidate Trials. PT303 has gained National Listing and its results from the independent AHDB Candidate List trials have now been published. PT303 delivers the highest gross output yields in each AHDB region – including a UK region yield of 111%. It has consistently given top yields across multiple trial programs and provides tolerance to a disease that is associated with the increasingly common high rainfall events experienced in the UK. PT303 also combines proven TuYV resistance and multigenic Phoma resistance for a best in class overall disease resistance rating. What is sclerotinia and how does it affect oilseed rape? Sclerotinia is a soil-borne fungal pathogen, which can remain viable in the soil for up to 8 years. A single sclerotium produces 10 – 14 apothecia which in turn produce 10 – 14 million spores and it can affect many crops, including: oilseed rape, peas, beans, lucerne, carrots and potatoes (>400 host species). Sclerotinia is usually the main disease to impact OSR at the important flowering stage and in severe infections the yield impact can be over 50%! Although epidemics are uncommon, localised infections occur most years and the inoculum burden continue to build if infections are not controlled.
