They tried it this year, and surprise surprise, not all of the ones that were supposed to die actually died, (or didn't become sick enough to become sterile) resulting in some "artificial" DNA now wild in the breeding gene pool. It was supposed to be limited to sterile males or fathers that could only offspring sterile males. Actual impact TBD. But population did decrease significantly for months.
