JChamb - 8/2/2024 08:37 Had my fungicide/insecticide on my corn sprayed with a drone. I was impressed, you could see the product getting all the way through the canopy. I feel like it did a better job than the helicopters I have used in the past but I can't say for sure until plants start to mature. The guy that did mine runs 3 drones, could do 100-120 acres/hour.
