Abstract:

In this study, foreign herbs, densities and frequencies of occurrence found in Manisa and Muğla's almond production areas have been studied. Surveys; in 2017, in Manisa or Akhisar and Kula districts, in Muğla province Datça districts, in randomly selected fields, were carried out in two periods (summer and spring). In 28 gardens, 680 hectares of area were examined.

In the survey, a total of 62 species of foreign herbs belonging to 27 families were identified. 1 of these species are parasites (Viscum album L.), 13 are narrow-leafed and 40 are wide-leafed foreign herbs. In the province of Muğla: the highest of foreign grass density and frequency of appearance in large leaves of foreign herbs is Oxalis pes-caprae L. (18,57 pieces/m2; 60%), Raphanus raphanistrum L. (16,03 pieces/m2; 56%), Convolvulus arvensis L. (5,36 pieces/m2; 20%); Sorghum halepense (L.) from narrow leaves.  (8.72 units/m2; 38%) are in Cyperus rotundus L.

(18,57 units/m2; 45%), Crepis spp. (16.12 pieces/m2; 55) Matricaria chamomilla L. (15.19 pieces/m2; 65 %), Senecio vernalis (9.48 pieces/m2; 32 %), from narrow leaves Cynodon dactylon L. and Pers. It is found that there are (20,89 pieces/m2; 35%), Poa annua L. (20,5 pieces/m2; 31%), Bromus tectorum L. (18,57 pieces/m2; 28%).
