Last fall I seen 2 crop dusters spraying together in a 1400 acre field for Bertha army worms. It was foggy when they started and I don't know how they didn't crash. I have heard when they spray our canola that if they don't come back with flowers on their tires they are flying to high. Not sure if that's just an exaggeration or not. With our 100 foot sprayer doing 18 miles per hour I sprayed 20 acres in the same time the crop duster did 160 ac across the road.
