Narrative:

I was contracted to spray on a local ranch. The field I attempted to spray, I made 2 passes of spray on the field, when another agriculture aircraft arrived and started spraying in the middle of the same field. I pulled up and out of the field I was spraying and circled around to observe the situation. The other aircraft kept spraying, so I retreated to our home base. The farmer said there were to be no other aircraft working this field at this time. I didn't see an incident occur, but we were in close proximity on the same field. The farmer contracted us to spray his field. The texas boll weevil eradication program decided to spray that field at the same time.
