Not to my knowledge. I can't see any difference. I think the really important part is to get a product down where it's needed, in the lower canopy. A lot of these fungicides do not really move too much.
Fungicides are very local, systemic, or some of them are even just contact fungicides, so it's important to get them down in the bottom of the canopy. This pathogen will show up first in the lower part of the canopies, so we need to get good coverage and penetration. You can get that by airplane or ground rigs, as long as you follow the recommendation and labels. – Palle Pedersen
