Pilot knows he is spraying fungicide all day. Farmer Bob sprays Quilt. Farmer Joe sprays Headline. Farmer Fred sprays Approach. Pilot lands a dozen times to load, always in a hurry and is looking at his maps and such while the tank fills. Why is is so hard to believe that off the top of his head he can't remember specifically what he got loaded with at 10 am when he's sprayed 9 loads since on many different fields?
Sorry attempt at "excuses". Does not match OP description of "pilot had no idea what he was spraying until he talked to the coop."
