This research was conducted to determine the effect of different doses, which are the most common use as seed chemicals on the germination values of the seed in sunflower and corn cultivars. The research were carried out accordance with the 3-factor randomized plots experimental design in Limagrain Group / Bursa seed laboratories. Aprin XL 350 ES fungicide for sunflower in the study; 0, 200, 250, 300, 350, 400 ml and Cosmos 500 FS insecticidal; 0, 300, 400, 500, 600, 700 ml and the Maxim XL 035FS fungicide; 0,50,75,100,125,150 ml and Gaucho FS 600 insecticidal; 0,400,500,600,700 and 800 ml for corn was applied in doses. Sprayed seeds were stored for 10 days and 180 days and germination trials were conducted. According to the variance analysis results; at the end of the 10-day storage period for sunflower, the pesticide x dose interaction was statistically significant at the level of 5%, and at the end of the 180-day storage period, it was statistically significant at the level of 5% in for doses. According to variance analysis in Corn, after 10 days of storage period, cultivar and dose applications were statistically significant at 1% level, while cultivar x pesticide interaction was significant at 5%. After 180 days of storage, 1% significance was detected in all applications. As a result of the study, it has been determined that the germination values of Aprin XL 350 ES over 300 ml dose routinely applied in sunflower are negatively affected, and that this is not the case in Cosmos 500 FS application. The best dose was found to be 300 ml for Aprin XL 350 ES and 600 ml for Cosmos 500 FS. In corn, the most suitable pesticide dose varies according to cultivars and it is determined that both pesticides applied to the seed decrease the germination rate of corn in increasing doses.
