Focus on weed control in spring cereals

With a large backlog of on farm activities to contend with following a miserable autumn and winter, once drilling of spring cereals is over, growers should turn their thoughts to spring weed control as a priority.

Spring barley has the potential to reach quite high levels, if weather allows drill to get moving. Although the basic principles of weed control may be carried over from winter cereals, Corteva advises some fine tuning to programmes may be necessary to ensure maximum efficacy in spring crops.

Spring barley will race through growth stages once temperatures rise, so growers should be ready to take out weeds early to prevent any competitive effect on yield and problems at harvest.
Product choice and application timing are two important decisions that farmers will need to consider. A residual application this spring is unlikely, due to time constraints, so growers should plan a robust broadleaf weed control programme.

Arylex™ active (found in Pixxaro® and Zypar®) can be applied early season from three leaves, all the way through to growth stage 45 in winter and spring cereals.

Both products deliver outstanding control of key difficult weeds commonly found in spring cereals, including cleavers, poppies, cranesbill, chickweed, bindweed and of course the Achillies heel of sulfonylurea chemistry – fumitory.

For maximum control, weeds should be treated early, when small and actively growing, this way yield robbing weeds can be taken out before they start to compete with the crop.

Activity on Polygonum species can be boosted by adding a sulfonylurea herbicide such as Harmony® M SX® to the mix. Arylex chemistry comes with a wide range of tested tank-mix compatibilities, including PGR’s, fungicides and other herbicides, allowing growers to make the most of limited spray opportunities and apply the tank-mix of their choice.

Following crop choices are not limited by the use of Arylex products either, giving growers the greatest choice of planting options the following autumn, with no cultivation restrictions.

Drive a profitable yield with Univoq™ fungicide

Recent winter wheat field walking has supported the view that the wet weather over winter has led to significant levels of septoria in crops and the current rising temperatures are increasing the levels of yellow rust. Therefore broad spectrum fungicide product choice is going to be vital this season at both T1 and T2.

Whether tested in the field or across independent trial sites, Univoq fungicide has shone brightly as a unique solution for broad-spectrum cereal disease control and leading yields.

Robust in the face of septoria and rusts, the coformulation of the novel Inatreq™ active molecule in combination with prothioconazole is optimised by Corteva Agriscience’s patented i-Q4™ formulation.

The result is a unique fungicide with no cross resistance to other chemistries, enhanced spray retention, and the ultimate in coverage, penetration and uptake. Univoq provides lasting protection for your crop, laying the foundations for higher yields.

But don’t just take our word for it. Read what users had to say:
 
Septoria suppression in Suffolk
Suffolk farmer Oliver Pipe opted for Univoq in 2023. Farming on the edge of Ipswich he applied Univoq to winter wheat at the T2 timing and winter rye at T1.

“Using Univoq was a decision I made with my agronomist as to what would give us the most bang for our buck. It was one of the top-performing products and definitely the most competitively priced.”

“When we applied it there wasn’t much disease to clear up, so the Univoq just quietly got on with its job and the crop stayed green. Yields were good – there are so many variables you don’t know if it’s down to any one thing in particular, but if you’ve kept it green you know it’s going to be alright.”

A fifth year of reliability for Northamptonshire grower
Andrew Mahon has used Univoq for five seasons running as it “does what it says on the tin.” He grows 350 ha of wheat and last year used Univoq across 300 ha.

“We went for a lightweight T1, preferring to spend our money at T2. Most of these varieties have a pretty good disease profile, with reasonable scores for septoria and some inherent resistance.”


Best options for septoria disease control in wheat
In case you missed the article in Farmers Weekly on 16 February, here’s what was said:

“The most effective fungicide for controlling septoria in wheat has been found to be Univoq, which is slightly ahead of SDHI-azole combinations, according to independent trials carried out by crop consultant NIAB.”

“The picolinamide-azole combination shows the best curative activity against wheat’s most damaging disease, which gives it an edge over other broad-spectrum fungicides…”

The product has been the best for septoria control in the two high disease pressure years of 2022 and 2023. Read more here.
