There were some plant diseases on potato, wheat, corn, bean and animal diseases such as feed refusal, weight loss, death of cattle and sheep as well as chicken mortality in northwest Iran. Infected plants were collected and cultured in PDA as common medium and Peptone PCNB Agar (PPA) as selective medium for Fusarium species after surface sterilization with sodium hypochlorite. Several Fusarium species were isolated from samples counting potato tubers, wheat, corn, plant residues and animal feeds in the fields and storages. Actually, Fusarium species were the major pathogens causing significant diseases on potato, bean, wheat, corn, rice and alfalfa as the key human food and animal feed in that areas. Study showed most plant and animal diseases especially chickens mortality were attributed to feeding infected plant straw and contaminated feeds in considered areas. Mycotoxin producing species including F. solani, F. oxysporum, F. graminearum, F. moniliformei, F. sambutinum, F. culmorum and F. equiseti were dominant recognized isolates. The common Fusarium mycotoxins such as zearalenone, moniliformin and fusaric acid have been also discovered from these species. The results put emphasis that Fusarium contamination of feeds or foods can be capable of the harmful consequences on animal and human health.
