During a week of almost back-to-back Hutton periods, Scottish Agronomy has found a wave of active blight foci in Scottish crops.
Conditions were blight conducive throughout Scotland’s potato growing areas for the last week of July with spores present and active, Farmers Guardian reports. According to Scottish Agronomy’s Eric Anderson this marks the start of a heightened period of risk.
“This week we’ve submitted two samples from volunteers and four from crops to the AHDB ‘Fight Against Blight’ service. So far this season blight’s been a non-event but it has now kicked off big time.
“To keep on top of it growers need to step up frequency of inspection and be ready to adapt programmes to regain control.”
Where active foliar blight is found in a crop, Scottish Agronomy recommends products or mixtures with both anti-sporulant and tuber blight activity.
