SE IL | I’ve always heard 2-3 for drones and planes. Will be interesting to see some side by side comparisons if someone can make some accurate ones for fungicide. Maybe newer fungicides are different but I always understood that fungicides are not systemic, they do not translocate, and thus are only going to protect the lead area they touch. So in my mind it’s like gramaxone, liberty, PPO burners back when they worked; you need full coverage of the leaf to kill the weed. With these you need high water volumes to make sure coverage is complete. 15 gpa is usually said to not be enough, you need 20. How aerial applications can get the same coverage with 2gpa is something I’m not convinced of yet. Of course the actual volume of true product (fungicide in this case) is the same for Ariel and ground applied. You can get nozzles to apply very fine droplets at 10 gpa with a ground sprayer, so why wouldn’t it be enough and we are always told 20? Kind of my rambling thoughts. | |
