Spreading the risk for growing oilseed rape

The loss of neonicotinoid seed dressings has made growing oilseed rape extremely challenging for many growers. However, if you can get a crop of oilseed rape established there are very limited alternative break crops that offer the same same gross margin to farm businesses.

The breeders recognise the issues of establishing oilseed rape on farm and are now offering establishment schemes with certain varieties to spread the financial risk to the grower if the crop fails. Variety's available on establishment schemes:

  • DK Exstar (DEKALB Hybrid)

  • BLAZEN (KWS Conventional)

Both DK Exstar and BLAZEN are good yielding varieties, offering a strong agronomic package and have good autumn vigour.

RGT Beetleblocker:

With OSR becoming a more challenging crop to establish, various techniques have been tested to try and reduce the impact of flea beetle on emerging crops. Trials carried out by Semences de France last year have led to the creation of RGT Beetleblocker, which can reduce the number of flea beetle in a crop by up to 75%.

RGT Beetleblocker combines RGT Blackmillion OSR , Fenugreek and Berseem Clover together in one homogenous mixture that can be sown in a single pass. The fenugreek gives off an odour which repels the flea beetle and, along with the berseem clover, also fixes nitrogen which will be available to the OSR crop as it grows. The key to getting the most out of this product is early drilling, giving the companion crops plenty of time to get established. This should be planned for 7 to 10 days earlier than you would normally drill your OSR. Trials carried out by Semences de France last year have led to the creation of RGT Beetleblocker, which can reduce the number of flea beetle in a crop by up to 75%.
