Organic which usually refers to organic produce are from cleaner farming practises which does not involve or restricts the amount and type of pesticides and fertilisers used in the farming process. It is usually processed without the use of irradiation, industrial solvents or synthetic food additives. However the definition internationally is different and there isn't any institution to govern the practice - so generally, a cleaner and better farming practice
Organic fruits and vegetables basically means the produce are grown without the use of pesticides, synthetic fertilizers, sewage sludge, genetically modified organisms, or ionizing radiation.
