FYI
It takes 7 years to accredit farm soil as Certified Organic. That's due to the fact some herbicides & pesticides do not 'disappear' in one growing season.
I applaud your question.
In today's world, retail goods come from world-wide sources where there are no bans on chemical use.
I wish you happy gardening.
