Field studies were carried out in the years 2001–2003 on the susceptibility of 11 pea cultivars (Ametyst, Cyrkon, Diadem, Kujawiak, Kolia, Komandor, Perła, Piast, Rola, Set, Stig) to damage by larvae of pea moth. Pods of cv. Stig, Perła and Kolia were heavily damaged by pea moth, ranging from 9.2% to 41.7%. The lowest per cent of damaged pods was shown for the cv. Set (7.0%) in the year 2001; cv. Cyrkon (3.7%) in the 2002 and in cv. Ametyst (12.0%) in the growing season 2003. The average yield of pea cultivars ranged from 26.1 dt/ha to 35.6 dt/ha. Cultivars of semi-leafless pea produced the highest yields, and their average yield amounted to 33.4 dt/ha.
In the years 1992-1994, studies were carried out on the occurrence, harmfulness and chemical control of the broad bean weevil on broad bean crops at different dates. A maximum of the beetle occurrence on the plantation under study was noted in III decade of June and in I decade of July. Seed damages caused by this pest ranged from 31.3 to 45.7%. The best time for the broad bean weevil control on broad bean was in the stage of pod formation. The application of the insecticide Karate 025 EC at the rate of 0.3 dm³/ha caused limitation of seed damages, on the average, by 19. 7%, which gave a mean yield gain of 0.3 4 t/ha.
