Early sowing prompts high biomass

20 Apr 2018

Jorin Grimsdale and his brother run the family business, Mountfair Farming, an agri-business specialising in contract farming & farm management services in the Scottish Borders & North Northumberland, based near Duns.

This year their Real Results Circle trial crop is Grafton, a first wheat, after vining peas. Mr Grimsdale said, “as we come out of early spring, the crop is looking even and well. It hasn’t been affected by the cold spell as it’s well established. It is quite a forward crop with good biomass. It had a Green Area Index (GAI) of 0.55 in early March.”

There are, as yet, no disease issues with the crop. Mr Grimsdale said, “Septoria tritici and yellow rust are the main disease threats we have to consider when planning our T1 spray programme. We do take Eyespot into account, however, in this situation it is lower risk than a second cereal.”

At T1, currently it is likely to be Adexar (epoxiconazole and fluxapyroxad) at 1l/ha + 1l/ha chlorothalonil (CTL), although it is still early in the season so this may change. This will cover the main diseases and with a high yield potential, manages the risks. With quite an early sowing and high biomass there will be an expected higher level of disease in the crop.

However, if it transpires that disease pressure is low, then the Adexar would be replaced and used at the T2 timing. We would always have the higher spend at the T2 timing anyway as this is where there is the highest response to fungicides and the highest return.”
