The objective of this study was to determine the marketing structure of pesticides used in wheat production in Konya by using M-Firm Concentration Ratio (CRM) and Herfindahl-Hirschman index (HHI). The market shares of firms manufactured/imported pesticides were used in order to estimate CRM and HHI. The data on selling amount and selling price used in the estimation of market shares were obtained from the surveys conducted to pesticides dealers and from Konya Ministry of Food, Agriculture and Livestock Province and District Offices. CR4 of the biggest four firms, CR8 of the biggest eight firms, and HHI of the market of pesticides used in wheat production were estimated in research area as 66.29 %, 85.36 % and 1340.41 respectively. The high values of CRM and HHI, which are accepted as the measurement of the monopoly power, indicated that the market structure of pesticides used in wheat production was a oligopoly type of market structure in Konya.
