I’m fed up with talking about the weather, but I can console myself with the fact we have grabbed every opportunity so far and progress is not too bad.Aerial spraying for blight as ground conditions worsen
NEARLY 1,000 acres of blight–threatened potatoes were sprayed by helicopter in south west Lancashire this week as ground conditions became impossible for wheeled spraying equipment.
The specially-adapted helicopter, which normally sprays only bracken, was contracted in by agronomy and agrochemical company County Crops.
Managing director Mike Forshaw said if ground conditions did not improve, it might be necessary for some growers to use the aerial spraying service again.
Only three products are now permitted for aerial use – this week the Lancashire crops were sprayed with a benalaxyl and mancozeb mix.
More than two decades ago, low potato prices and severe operational restrictions on aerial spraying brought about its demise but the current cost of around £30 an acre, set against this year’s anticipated potato prices – and the investment already in the crops – has made it a worthwhile gamble to try and stave off the disease.
