Oilseed rape: from Hybrid to Harvest
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.

SEPTEMBER UPDATE: Growers are facing a split season: early-drilled crops with moisture are thriving, while others are only just emerging after recent rains. But with low cabbage stem flea beetle pressure and high soil temperatures, there’s still time to drill - and the world record OSR yield was achieved from a mid-September sowing!
Belkar® herbicide offers flexible post-emergence weed control tailored to crop growth stage. Apply 0.5 l/ha from 15th September once 90% of the crop reaches 6 true leaves (GS16), or 0.25 l/ha for smaller crops. It targets a wide spectrum of broad-leaved weeds - mayweed, fumitory, cranesbill, shepherd’s purse - and supports tank mixes with graminicides, fungicides, insecticides, and boron-based nutrition.
With OSR prices rising to £400/t, new high-oil varieties and strong gross margins, oilseed rape remains a profitable break crop.
But don’t forget to monitor slug pressure and apply pellets when thresholds are met.

Are you thinking ahead to your propyzamide applications later this season?
In line with best practice guidance from the Voluntary Initiative, simple steps should be implemented to help ensure that autumn and winter-applied products don’t reach watercourses. Learn more about propyzamide stewardship here.
