Hi. From what I’ve learnt – plants do have a filtering system (more like a firewall). Systemic pathogens usually get in through stems or leaves not roots. This doesn’t stop root crops from having localised root pathogens … they just don’t travel very far upwards, generally speaking. I hope this helps & hasn’t put you off carrots & potatoes.
