Cut my first tomato today, a hybrid variety but it had this rot with a couple of moth looking bugs on it. I just cut around it. Should I be concerned if it keeps happening. Any help identifying the problem would be appreciated.
It split, then secondary rot set in. No need to spray, etc.
Agree it is just splitting that has scabbed over. Search 'splitting' here for all kinds of info on what causes it and how to prevent it.
