Farmer in Canada I worked for paid the crop sprayers to fly over his beans a few times one night to stir up the air to stop the frost.
That is something they tend to do in N America. OK if nobody else wants the planes for the same job. Other countries use the frost fans that Cornish tones mentioned above. The idea is to cause sufficient turbulence to disperse the frost, or, ideally, use the fans to pull down the warmer air and raise the temperature enough. Not really feasible on a few thousand acres of cereals though.
