12 October 2026, London: FMC Agro has secured UK approval for two new formulations of its insecticide active ingredient cyantraniliprole, extending the chemistry’s reach into potato and carrot production, according to the October 2026 update of the UK Pesticide Guide (UKPG) database maintained by the British Crop Production Council (BCPC), published on October 5, 2026.
The update lists Preza 10 OD, a 10 percent cyantraniliprole formulation, approved for use on potatoes up to the point before first berries become visible. A second formulation, Benevia 10 OD, also built around cyantraniliprole, received approval for use on carrots, though the BCPC database notes that the product label had not yet been received at the time of publication. Both approvals fall under Great Britain’s pesticide authorisation framework, which is administered by the Health and Safety Executive’s Chemicals Regulation Division (HSE/CRD); BCPC’s UKPG compiles and republishes CRD’s approvals data as the industry’s standard reference, and that compilation is the source for this update, since CRD’s own register could not be queried directly for this specific monthly batch in the time available.
Cyantraniliprole is not a new active substance in the UK, where it is already approved under other brand names for several horticultural uses. The news here is incremental but commercially relevant: two additional formulations targeting potatoes and carrots, two of the UK’s largest field vegetable crops by planted area, give growers another tool against lepidopteran and other foliar pests without requiring a fresh active-substance approval process.
The October update also carried a broader slate of changes across the UK market. BASF added three products built on mefentrifluconazole, a triazole fungicide it has been expanding aggressively: Revysense, a straight 97 g/l mefentrifluconazole formulation pending confirmation of marketing intent, and two combination products, Yanila and Stelya, which pair mefentrifluconazole with prothioconazole and replace earlier BASF plc registrations, with approvals extended to September 30, 2029. Syngenta added Miravis Era, a Great Britain-only combination of prothioconazole and the newer active pydiflumetafen, aimed at cereal disease control, also pending label and marketing confirmation. Sharda Cropchem registered two formulations of deltamethrin, Phobii Grain Store Pro ULV and a related EC version, specifically for stored grain and pulses, approved through December 2030 and February 2029 respectively. Life Scientific, a specialist in post-patent generic registrations, added a lambda-cyhalothrin product (Tarak) and a pyraclostrobin product (LS Pyrac).
A significant share of the remaining October entries were parallel or duplicate registrations rather than genuinely new chemistry: Adama’s Piotrol and Impelos mirror a BASF azoxystrobin-mefentrifluconazole mixture already on the market, Clayton’s Tonus duplicates an existing pyriproxyfen registration with an extended expiry date, and Fine’s Kudos does the same for a prohexadione-calcium product. These filings reflect the UK’s active secondary-registration market, in which companies register equivalent versions of already-approved products, often with longer expiry windows, rather than true innovation.
