I have had this problem with a horse that I wanted to catch. I ran him in a five acre field for five hours to tire him out. When he figured out that I wouldn't go away, and that standing was easier than running, it was only a matter of time, before I had a halter on him. However, like so many other posts here, this is a nice story that doesn't help you.
What I understand is that you have limited time and limited resources to complete this game of "catch." Your only choice is to restrict his ability to move. That's your only choice. It is obvious to you that the wire fencing is not going to restrict him, based on past performance. Also, you have said that this boy doesn't respect a trailer/box.
This is only my inexperienced opinion, but I see that you have two choices: rope him from another horse or build a pen in the field. Since you have already rejected the idea of roping, that leaves you to build a pen. This is you only choice. I have used this method of entrapment with good success, for goats, horses, and cattle.
You build your pen along one side of the existing fence, using the fence as a funnel to direct your horse into the pen. Then you move him, using body language and groups of people that you can gather. (I have done this alone.) I have used a pen that was built of five foot tall metal gate panels. (I wouldn't use wood because if the horse attempts break through, they very often succeed because of body weight. This would be more dangerous.) I have used a 20' X 20' pen as well as a 10' X 10' pen. Leave one panel open to allow you to close the "door" once the horse enters the pen. I have successfully used a rope tied overhead to pull the gate shut from a distance, but this is much harder because you have to drag the gate panel across the ground, making noise and scaring the animal, to get the door closed. There is danger in this method because the horse will perceive the threat of entrapment and attempt to escape by running over you or whom ever is attempting to close the gate. Cattle love to do this, so you must be very careful to avoid being run down.
If you have time, which I am not sure you have, you can do as others have suggested and feed all the horses in the temporary pen you must build to desensitize them to the presence of the new pen. However, it sounds as if you are out of time.
Considering the conditions that you have outlined, it would seem that this land owner is less than helpful and it sounds as if you are taking you horse out of that situation anyway, which would be good. I would consider hiring a cowboy to rope your horse, even if objected to by the land owner. If you're leaving, who cares what they think. Shoot, I'd figure out a time when that owner might not be present to witness your transgression and do it anyway. It would seem that this land owner doesn't care enough about your horse to provide safe field conditions that should at a minimum include shelter and weed control.
Hope you get it worked out.
