This study was conducted in the period of growth of anason in the fields of organic anason cultivation in Burdur-Tefenni (June-July) in the years 2015-2016. Diagnosis, intensity and frequency of foreign herbs in organic anasons was the main objective of this study. In the 2015 survey, 82 foreign herb species were diagnosed in 28 families. In the field and on the edge of the field 50'sher species showed output. During the vegetation period of 2016, 94 foreign herbs were identified from 29 families. There are 71 species in the field and 58 species on the edge of the field. In the 2015 survey, Asteraceae (18 sp. Poaceae ( 9 sp., Brassicaceae (7 sp.) and Fabaceae (6 sp.) There were dominant families in the field. In 2016, Asteraceae (14 sp), Poaceae (14 sp), Fabaceae (7 sp), Apiaceae (6 sp) were the most species-containing families. According to the frequency of occurrence in the field, in 2015, Convolvulus arvensis (83%), Cynodon dactylon (58%), Chenopodium album (41%) were the primary species. However, on the edge of the field, Lactuca seriola (58 %), Centaurea solstitialis (52 %), Avena sterilis (47 %), Bromus spp. (%41) C. arvensis showed the highest frequency of occurrence. In 2016 in the field in C. arvensis (70%), Ch. album (%52), Chondrilla juncea (%41), Cy. The dactylon (37%) species were the species with the highest frequency of occurrence. The same year on the edges of the field L. seriola (58%), C. Solstitialis (52%) and A. sterilis (47%) have been dominant species.
