Protect your OSR yield from the start for the best possible finish

OSR Autumn

OSR re-invigorated within the rotation

With grain prices 23% (£58/t) higher than this time last year, the value of OSR within the rotation is being re-invigorated. But careful consideration beyond just gross output should be assessed when selecting varieties.  For example, it is important to consider the impact a variety with inherently high oil content can have on your oil bonus, and ultimately the profitability of your OSR crop.

The impact of the increase in grain price, combined with selecting a variety with high oil content, is clear when examining income per hectare. InVigor 1030 (InV1030) has the highest in class oil content (47.1%), which combined with its high seed yield, means you can achieve an additional £526/ha, when comparing June 2017 with June 2016, an increase in income of 36%.

With that type of potential increase on offer, oilseed rape remains the most profitable entry for first wheat. But with the same pest and disease pressures as those that struck in 2016, variety decision making is more important than ever.

Growing OSR presents growers with numerous elements out of their control, and so it is important to focus on those elements that can be controlled. This means taking a more holistic view of variety decision-making, considering all agronomic characteristics of a variety, including autumn and spring vigour, as well as the variety’s seed yield and oil content, and how these will ultimately impact on oil bonus and overall income.

Get your OSR crop off to a flying start this autumn

Establishing a strong OSR crop can often be unpredictable with the challenges of controlling disease and pests and coping with changeable weather patterns, but there are many things you can do to give your crop the best start possible. The first consideration for a successful and profitable crop is variety choice. Choosing an InVigor hybrid which shows good early development and strong autumn vigour, will improve your chances of establishing a viable crop. Find out more about the benefits of hybrid OSR here.

Phoma is a widely known challenge for OSR and a priority disease to control by growers around the country, but light leaf spot needs to be a key focus too. Light leaf spot is as significant in OSR for reducing yields as Septoria is in wheat but it is often difficult to identify so we've developed some useful resources to help you identify light leaf spot and reduce the impact it has on your final yield. 

Another danger to establishment and yield is the peach-potato aphid (Myzus persicae), the main carrier of turnip yellows virus on to OSR crops. These critters can hit hard and reduce your final yields by up to 30% so it's important to monitor your crops for signs of these aphids colonising. You can find out more about controlling these pests here.

We can't control the weather, but we're here to help you get the best start possible for your OSR crop this autumn.

Top Tip 1

Drill into the right conditions.

Early sowing generally helps oilseed rape outgrow pest threats and ensures good crops going into winter, but only if there is adequate moisture to allow seedbed preparation and support germination. Avoid rushing drilling into very dry or cloddy seedbeds and be prepared to wait for suitable conditions – tailor cultivations to soil type and season. Most conventional varieties can be sown up to mid-September, while more vigorous hybrids can be sown through to the end of September. Later drilling may also help avoid the main flea beetle migration period.

The benefits of Hybrid OSR

Don't let TuYV-carrying aphids damage your yields

Peach-potato aphids (Myzus persicae) are the main carriers of turnip yellows virus (TuYV) onto OSR crops and AHDB monitoring suggests up to 72% of aphids are infected, meaning even small numbers of aphids can spread the virus widely. Young OSR plants are particularly vulnerable and AHDB estimates average yield losses from the virus of 15%, but these can be as high as 30%. Signing up to the AHDB ‘Aphid News’ email bulletins on Myzus persicae is a great way to keep informed of any aphid migrations.

AHDB monitoring also shows the UK field populations of Myzus persicae have very high levels of MACE and super-kdr resistance meaning carbamates and pyrethroids will be ineffective. Biscaya controls MACE and super-kdr resistant aphids so is ideal for your first spray in the autumn as soon as you see aphids colonising. Its fast knockdown activity means it stops aphids quickly, reducing the chance of infection being spread, with protection for up to 2 weeks.
