The spraying of wheat etc with Roundup isn't usual practice but is done in certain circumstances.
The wheat has already stopped growing and is drying off at that stage so the Roundup doesn't affect it's growth.
Not a practice I'm enthusiastic about, but I know farmers who say that the resulting lack of weeds etc in the harvested grain improves storage quality etc.
I've eaten Ground elder in the distant past - we steamed it and incorporated it in mashed potatoes, like a sort of champ, and also in a minestrone-type soup. Quite edible but not an outstanding flavour, but my reasoning was that if it became aware that we actually wanted it to grow it was more likely to do the opposite
However, we moved house before the trial came to an end!
