The USDA only permits very specific and highly restricted pest control substances to be used under the "organic" label [1]. So yes, they may still use pesticides, but they are miles away from the usual pesticides used in conventional farming. That stuff will literally kill you if you aren't careful [2]. Beware that there is a lot of misinformation out there targeting anything that dares to go against the conventional farming industry. Of course not all eco hippie alternatives are great, but the usual stuff out there is without question outright terrible in many cases.
