Show your OSR some love. Spring clean weeds with Korvetto
 

14 February 2024

Spring clean your oilseed rape with Korvetto
As spring emerges after a tough, wet but 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.
Weeds Korvetto controls
Timing of Korvetto application is from 1st March during stem elongation up to before flower buds are visible above the canopy (BBCH 30-50) 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®.
