Farmers in Wiltshire say crop circles people cut into their fields are damaging their trade and costing them up to tens of thousands of pounds.
Enthusiasts call it a 'spiritual phenomenon' but farmers are urging people to stop.
Of the 28 crop circles reported worldwide this year, three quarters have been in Wiltshire.
While this puts the county on the map, farmers like Tim Carson say there is a cost to farmers of having so many crop circles.
The damaged crops cost farmers business and they also have to pay to grow replacement product.
Farmers say that as the fields belong to them, nobody else should be trespassing and destroying their crops.
Some farmers are trying to use the formations to do good.
James Hussey, whose family have harvested in Wiltshire for a century, is charging people entry to see the crop circles in his field.
The proceeds will go towards buying radiotherapy equipment for Swindon.
Mr Hussey, whose wife Gill died of cancer three years ago, says the fundraising effort has so far been a massive success.
