Oilseed Rape

We know that growing oilseed rape can be challenging so we have gathered together everything you need to know about oilseed rape here. From establishment to harvest we can provide insight about crop management and protection to help maximise yields.

What's happening in oilseed rape in September

Despite the summer drought conditions, the rain towards the end of August came at just the right time. Most of the country’s oilseed rape was drilled by the beginning of September, with only a few late-drilled exceptions remaining.

In September, pay careful attention to how the crop is establishing and any factors such as pests and weeds that may be impacting growth. If growing multiple varieties on-farm, compare progression in the early stages, above and below ground, as this could help inform next season’s variety decision-making.

Priorities this month (location dependent):

  •  Assess weed risk and monitor for cereal volunteers
  • Monitor pests and if necessary consider control options  




What’s happening in oilseed rape

With most of the oilseed rape harvest completed, attention turns to the 2018/19 season. Variety decisions will need to be finalised, remembering that a vigorous and resilient hybrid variety may be necessary for establishment, given the extremely dry summer conditions.

Careful consideration towards cultivations will also be vital. For example, minimum tillage will reduce the likelihood of weeds and cereal volunteers. Rolling after drilling will be critical to ensure good soil to seed contact too.

Priorities this month (location dependent): 

  • Assess weed and volunteer risk
  • Prepare seed bed
  • Finalise variety choices and establishment method


What’s happening in oilseed rape in May

The long awaited warm weather in mid/late April caused an intensive period of growth in oilseed rape across the country. Most crops were one step ahead of the pollen beetle migration, although some fields badly affected by pigeon damage and the Beast from the East may not have been so lucky.

Now attention turns to protecting and enhancing the potential held within the crop for an effective return.

Priorities this month (location dependent):

  • Flowering sprays for Sclerotinia control
  • Monitoring seed weevils
  • Management of light leaf spot


What’s happening in oilseed rape in June

The flowering period for most oilseed rape crops has passed, with crops now moving on to pod development. As June traditionally tends to be a quieter month for oilseed rape, now is a good time to start thinking about variety selection for the 2018/19 cropping season.

Remember that while establishment conditions were kind this season, conditions in the 2016/17 season were much more challenging. To overcome these challenging conditions it is worth considering a resilient, highly vigorous variety.

Priorities this month (location dependent):

  • Monitor crop development
  • Plan pod sticker and desiccation approaches
  • Consider variety choices for 2018/19 season 


What’s happening in oilseed rape in July

Oilseed rape crops will benefit from the increase in temperature as plants continue to develop seeds within the pods. During this time, it is important to regularly assess seed maturity in order to best time pod stickers and crop desiccation.  

Now is a good time to finalise variety decision-making for the coming season, remembering that a resilient, vigorous variety will stand you in good stead should establishment conditions be a challenge in the autumn.

Priorities this month (location dependent):

  •     Assess seed development
  •     Apply pod stickers if necessary
  •     Attention to detail on desiccation timing
