Oilseed Extra is a unique concentrated foliar formulation designed to rapidly boost the nitrogen content of oilseed rape crops during the critical pod and seed development stages.

It is formulated with magnesium, sulphur and a micronutrient complex of manganese, zinc, copper and molybdenum to maximise the yield response. The formulation also includes crop safeners to minimise any risk of scorch plus a biostimulant to maximise crop response.

Magnesium is an important nutrient for oilseed rape as it helps transport photosynthesates in the plant and is a component of the enzyme rubisco, which facilitates oil production in oilseeds. Copper and molybdenum have also been shown to increase oil content when applied post flowering, at the Oilseed Extra timing.


Use Oilseed Extra to boost yield in oilseed rape.

Apply 200 l/ha, for best results apply early morning or late evening and add a further 100l/ha water.

The spray tank should be filled with Oilseed Extra whilst maintaining constant agitation. Add water to correct dilution and continue to agitate before spraying.


Do not apply in adverse weather conditions or when crop is under stress.
HGCA work recommends application of foliar N any time between mid-flowering and two weeks after the end of flowering.

Petals do not absorb nitrogen, so applications to flowering crops can mean much of the nitrogen is not utilised. One of the main drivers of the responses is the prolonging of growth as the pods fill and the seed matures, so later application (after all pods are set) is more effective.
