What can I spray on cotton to keep DEER out of the field. They are horrible this year.

Bullets. I'm with  *. We killed 28 early in the year. 22 turkeys, and some other stuff. Now time to kill more for the emerging fall crop. Probably kill that many again. hunters stay pissed off, but landowners don't halfway want hunters on land anyways, so I got unmanageable farms. Funny thing the ones with the least action are always leases for hunting. Most I've seen in a field (and my avg is 10 acre) was 105 turkeys at once beating cotton to death, 28 geese in a southern pea field eating seed, and 20 deer chowing down on yellow peas.
