Testimonials
James Barlow - ADM
RGT Highrove stood out instantly!
Crops looked as good as they have done for long time, nice and even and all standing,” says director Martin Cook.
“But yields are not happening to the extent we expected or wanted, which seems to be a problem in this part of the country. I think the poor weather at the end of June and early July has been the main problem – wet weather from May onwards is never good for us, as the silts cope much better in the dry.”

Yields on the grade one silty loams are generally coming in around the five-year average of 10t/ha – the farm grows quite a few second wheats plus drill into November after roots.
The 18ha block of RGT Saki, drilled after potatoes on 9 October and grown for seed, was in line with that figure, despite high disease pressure in early summer.
“It looked fantastic right the way through the season, until we were hit by late Septoria, which resulted in high disease presence on leaf 1 and 2 and 15% on the flag leaf,” says Martin.

HOW TO OPTIMISE THE USE OF YOUR VARIETY
Sowing
Keeping seed rates up on lighter land will help tiller retention.
It’s a bit different to last year when crops had torrid time but produced yield from nowhere.”
Yields on the grade one silty loams are generally coming in around the five-year average of 10t/ha – the farm grows quite a few second wheats plus drill into November after roots.
The 18ha block of RGT Saki, drilled after potatoes on 9 October and grown for seed, was in line with that figure, despite high disease pressure in early summer.
Fertilizing
suspect Septoria was bubbling way in May and June but didn’t show. Then we had 70mm in June and almost as much in July. The resulting disease, together with low light intensity, hit yield and specific weight.
“Last year the Saki looked average at best but yielded 11.5t/ha, our best performer. It is at the top end when it comes to vigour – it seems to tiller out very well and looks to be very competitive. Will it still perform if treated right? Will you be growing it next year?
Agronomy
“Local untreated trials went from almost clean to covered in few days. In hindsight, our T2 wasn’t robust enough. We didn’t apply a T0 as it was cool and dry, and crops were late and clean. At T1 we applied Wolverine (fluxapyroxad + metconazole) at just under half rate, and stand by that.
“But the T2 went on late as crops were slow developing. We applied 1litre/ha of Revystar at the end of May. I do think this was a bit low, plus we really missed Bravo.
Harvest
The fully replicated trials tested several RAGT varieties containing the Bdv2 resistance gene and a range of widely grown commercial varieties under the toughest conditions.
Plots were sown in early September 2020 and inoculated with virus-laden aphids, four times in the autumn and four times in the spring. No aphicide was used.
Plots were scored weekly for disease symptoms from mid-April to produce a visual assessment score (see graph).
Tom Dummett, RAGT’s cereal and OSR product manager, says: “The Bdv2 material, which included RGT Wolverine, Europe’s first winter wheat with resistance to BYDV, and three pipeline varieties, showed no symptoms, apart from a few isolated traces of yellowing, which can occur under high pressure.
