The term 'Banned Pesticide Apple' refers to the use of two chemicals, ALAR and TALC, which were used as pesticides on apples in the past but have since been banned due to their potential health risks. ALAR, or Aluminium Ammonium Sulphate, is a chemical compound used as a pesticide to control insects and fungi on apples. TALC, or Talcum Powder, is a mineral used as a pesticide to control mites and other pests on apples. Both of these chemicals have been banned from use on apples due to their potential health risks.
