Silver Nano-particles (AgNPs) were evaluated for its possible effects on the incidence and severity diseases gray mold for tomato fruits caused by the Botrytis cinerea. Treatments were [(healthy tomato fruits (control), inoculated tomato fruits by Botrytis cinerea, healthy tomato fruit with silver nanoparticles and combination inoculated tomato fruits with Botrytis cinerea and silver nanoparticles). The obtained results were: (a) there aren’t incidences and severity diseases of gray mold in case of tomato fruits with silver nan particles during forty days, (b) the lowest incidence (0.3) and severity (1.5%) diseases were after thirty days of cold storage in case of treatment tomato fruits were treated with Nano–Silver + Inoculated. While, the highest incidence (0.6) and severity (7.5%) diseases percentages were after ten days of cold storage in case of treatment tomato fruits with inoculated by Botrytis cinerea, comparison with incidence (0.3) and severity (1%) diseases percentages were after twenty days of cold storage in case of un-treatment tomato fruits (control), (c) the highest (TSS) percentage of tomato fruits which treated by Nano-particles followed by un-treated samples (control). While, the lowest was sample which treated by inoculated + silver Nano particles, followed by inoculated samples by Botrytis cinerea after forty days of cold storage and (d) the highest pH value of tomato fruits which treated by Nano particles, followed by un-treated samples (control). While, the lowest sample which treated by inoculated + silver Nano particles, followed by inoculated samples by Botrytis cinerea after forty days of cold storage.
