One of the factors that negatively affect the efficiency and quality of Egypt (Zea mays L.) is foreign herbs. In the fight against foreign herbs, integrated combat methods have been determined, and the economic damage threshold is the most important ring of it. This study determined the productivity losses and the economic damage threshold caused by Xanthium strumarium, which is a problem in the October areas of Tokat in the years 2014-2015-2016. It is also intended to reduce the amount of herbicide used for pigs in the eggs area in the province of Tokat to a minimum level and to use when necessary. Test random blocks are set in 5 wheels according to the test pattern. In addition to the external output control parcels 1, 2, 3, 4, 5, 7 and 9 pieces/m2 X. The parcels in Strumarium are created. The intensities created by controlling the parcels are preserved every day. After the Egyptian harvest, the Egyptian prices in the province of Tokat, the herbicide application costs were assessed and the economic damage threshold was calculated taking into account the current herbicide prices. According to the results obtained, the economic damage threshold of X. strumarium, which is a problem in the fields of the Tokat or Dada eggs cultivation, for the herbicite ARRAT (Tritosulfuron 25%-Dicamba 50%) was determined in 2014-2015-2016 respectively at 0.68, 0.28, 0.56 pieces/m2, INPUL 75 WG (Halosulfuron-methyl 75%), and 0.90, 0.53 and 0.81 pieces/m2 for the herbicite.
