I'm not getting ay benefit from your photos. Sorry, they don't show the wound itself in detail to determine what state of healing it may be in or if it's infected. Extreme well focused close ups are necessary to do that.
If you look at the puncture wound closely, and you need to try to get a glance at the crop sack puncture, as well, you will know that it's trying to heal if you see a raised rim of new tissue around the perimeter of the two wounds. This is called "granulation", and it means the wound is healing from around the edges toward the center.
That would be healthy and normal. But if you do not see this rim of new tissue, but instead see raw edges that may be red and swollen, and the wound seems to be as large as it was at first, then infection is underway and an antibiotic will be necessary.
Most crop injuries heal on their own with minimal care to keep it clean and free of bacteria. But you need to monitor the wound daily, not just clean and anoint it.
