Sounds like the ants might have an aphid farm going on your okra. Try washing them off with dish soap and water. The ants eat the honey dew secreted by the aphids so you have to wash it off. You will prob have to do it every day or so till they give it up. You can also try setting out ant traps at the same time.
If you spray once or twice with malathion it will take care of the aphids and thus the ants. Harvvest the okra for one week as normal, but throw it on thecompost heap as malahion stays active a good while. Its better than spraying a bunch of times with sevin. Malathion works on any thing with aphids.
