Just because someone is old doesn't mean they know all facts.It hasn’t been scientifically proven but my neighbor is an old timer 4 th gen farmer and he swears by it. I used it on mine and it has at least prevented any worms. I think there’s something to it but you know , it’s truly one of those debatable topics especially if one wants to be all natural and use only organic materials. Thanks for you onsite Isaac 0![]()
