The occurrence and harmfulness of pest in field bean cultivated in pure sowing and in faba bean mixed with naked oat was evaluated in field experiment carried out in 2006-2008. Faba bean plants in pure sowing were more severely infested with Aphis fabae and Bruchus rufimanus than in intercrops. The cultivation method had only slight effect on the occurrence of pea weevil. It is recommended to sow faba bean in mixture with naked oat in organic farms.
