This study investigated the effect of credit access on cocoa farmers’ willingness to pay for EU-approved pesticides in Osun and Ondo State, Nigeria. A multi-stage sampling procedure was employed to select 240 cocoa farmers for the study. Data collected were analyzed with the aid of descriptive statistics, contingent valuation method and logit regression model. The results for the entire respondents showed average values of 46 years for age, 23 years for years of experience, 7 persons for household size, and 8.54 hectares for farm size.  The majority (83.3%) of the farmers used Redforce. Given the current standard mean price of N365 per litre, the majority (62.5%) of the cocoa farmers are willing to pay 25% (price between N 365 – N 466) more on the actual price of the EU-approved pesticides. Logit regression estimates showed that gender, age, marital status, education, extension visit, access to credit, household size, farm size, and quantity of pesticide used significantly influenced cocoa farmers’ willingness to pay for EU-approved pesticides. This study concluded that credit access is an important variable affecting cocoa farmers’ willingness to pay for EU-approved pesticides. This suggests that policy strategies aimed at improving the cocoa farmers’ willingness to pay for EU-approved pesticides must consider their credit access. Based on the findings of the study, it was recommended that Government and agricultural-related organisations should provide credit to farmers to boost their willingness to pay for the approved pesticides.
