The experiment was carried out in Plant Protection Department, Faculty of Agriculture, Omar Al-Mukhtar University, to evaluate four Non Poison Chemicals. Two antioxidants (Hydro-quinone and Ammonium tartrate) and two growth regulators (Gibberellic acid and Naphtha-lene acetic acid)  were tested in vivo against grey mold of onion (Allium cepa) caused by Botrytis cinerea. The results showed that Gibberellins acid and Hydroquinone has highly significant effect on the rot area and disease severity of grey mold in storage and non storage onions. The rot area were recorded 8.4cm2, 10.4cm2 respectively compared with the control distilled water was 25cm2. Disease severity was decrease and it recorded (69.8%, 56.3% and 90%) in onion treatment with Gibberellic acid, Hydroquinone and distilled water. Disease severity also decrease when the time dipping is increased from 5 minutes to 10 minutes.
