Wheat growers are being urged to manage risk by taking on board the lessons of the “challenging” 2023/24 season when making this autumn’s drilling and variety decisions.
According to Syngenta seeds technical manager, Matthew Bull, as well as the big challenges of delayed drilling and intense Septoria pressure last season, other issues such as stunted root growth in waterlogged soils also affected winter wheat.
Bull said it is important to take these and other risks into account when planning for the new season, and to adopt strategies to help mitigate them.
“Septoria is exacerbated by early drilling, so if planning to drill early this autumn, look for varieties that have shown reliable Septoria resistance,” Bull said.
“This isn’t a guarantee that Septoria won’t develop, but it can buy some time against the disease if fungicide sprays are delayed.
“Also, look for other variety characteristics that are important if drilling early, such as stiff straw. Earlier planting increases lodging risk as it encourages taller growth.”
For feed wheat growers in England, Bull said the variety Graham is a good option in first wheat and earlier drilling situations, with its robust Septoria tritici resistance.
Because it came from a French breeding programme, he said it has “unusual genetics” in the UK and its disease resilience has held up well.
“Also important, Graham is slow growing over winter with a prostrate growth habit and late to reach the stem elongation stage, which helps protect it against frost risk,” Bull said.
“In farm situations, Graham has outperformed what you might expect from its AHDB Recommended List (RL) ranking, and its early maturity can spread harvest risk.
“With later-maturing varieties that start grain-filling later, yield can be affected if hot summers cause crops to die off prematurely.”
Where fields are being drilled later this autumn, Bull said SY Insitor is a good feed wheat option, particularly as a second wheat.
It also has the highest yield figure on light soils on the AHDB RL, at 106%, making it a useful option for planting after root crops grown on these land types, he said.
“SY Insitor also roots well, which is important if drilling later and on light land. The almost ceaseless rain and waterlogged soils during the first half of the 2023/24 season resulted in a lot of shallow-rooted wheat crops, because they didn’t need to grow deep to find moisture,” Bull said.
“In these situations, a variety that naturally roots well offers added security if it later turns dry.”
