Well .. it is at least one explanation, is it not?
Looking out of my bathroom window (the only one on that side of the house high enough to see over the hedge), I spotted these very odd .. well .. crop circles, I suppose. Leaving aside the possibility of aliens dropping in to say hello in a very idiosyncratic manner, I’m thinking that someone1 probably started to spray the wrong field with weedkiller – or maybe the right field with weedkiller instead of insecticide.
Either way, I doubt the farmer is terribly happy about the result. I mean, what happens now? If he harvests the rest of the field, surely he can’t allow any of the affected wheat into the food chain, and how on earth is he to make sure of that?
We rely too much on pesticides of one sort or another, I know that much.
