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.

FEBRUARY UPDATE

As spring emerges, after a relatively mild winter, broad-leaved weeds have continued to emerge and are ever present. 

Poppies, mayweeds, cleavers and thistles can not only out-compete crops – left unchecked they can also cause harvest headaches and create a seed return to the soil which compounds the problem in future years.

A solid autumn programme will have kept key problem weeds at bay, but early spring is an important time to monitor the emerging burden in the field.

Korvetto^® has excellent activity on the weeds that steal yield and cause issues at harvest. It contains Arylex™ active - the same active ingredient used in autumn herbicide Belkar^® - in formulation with clopyralid.

Timing of Korvetto application is from 1st March during stem elongation up to before flower buds are visible above the canopy (GS30-50) and it can be used from 8-25°C in humid or dry conditions. Avoid treating the crop when it is under stress, especially when frost is expected. 

There are no following crop restrictions in a normal crop rotation and farmers are free to use 1 l/ha of Korvetto if they have applied a post-emergence herbicide in the autumn such as Belkar or Astrokerb^®.
