Sown area with peas (Pisum sativum L.) has increased during last years, because it is good source of protein for feeding. Diseases of peas’ seeds could be harmful, especially if seeds are infected with fungi that can produce mycotoxins. Pea diseases have not been investigated in Latvia yet. The aim of the present study is determination of seeds’ infection and identification of causal agents. Pea seeds’ infection was assessed using average samples taken at SIA Latvi Dan Agro laboratory and prepared by Latvian standard LVS270:2000. Samples were taken six times between 29 th of July and 7th of September 2014. Pure cultures of pathogens were obtained from seeds and infection rate was calculated. Pathogens were identified by morphological features of fungal colonies. Results showed that harvest time and rainfall affects pea seeds’ infection with pathogen the most. On 27th July infection level was only 9.5%, but on 7th of September it was 76.5%. Alternaria spp. and Fusarium spp. were determined as main causal agents of infection. It means that risk of contamination with mycotoxins exists.
