This study was conducted in the years 2015-2016, in the Egean region, with the aim of determining the species, density and frequency of foreign herbs in the production areas of marul, maydanoz, dereotu, roca, tere, nane, semizotu, fissleugen from the leaves eaten vegetables. In 155 fields in 907.92 hectares, survey studies observed the representation of the area. Foreign grass species in winter and summer productions in these areas have been identified separately. The detection of foreign grass species in winter October was carried out in February-March, while the detection of species in summer October was carried out in July-September.

In winter in October: the most intense Stellaria media (L.) P. Beauv from wide-leafed foreign herbs. It is the most density of the bromus tectorum L. in the narrow-leafed foreign herbs, it is the most density of the bromus tectorum L. in the narrow-leafed foreign herbs, it is the most density of the portulaca oleracea L. in the summer, it is the most density of the narrow-leafed foreign herbs, it is the most density of the cyperus rotundus L. in the narrow-leafed foreign herbs, it is the Echinochloa crus-galli (L.) P. by Beauv.It was found to be observed. The number is the most common in winter production of the S. media and P. Annua species; in summer production of the P. oleracea and C. rotundus species.
