Climatic conditions in 1980 and 1981 were correlated with the incidence and severity of aflatoxin in maize at nine locations in the USA. Regression equations were developed that explained 80 to 89 % of the variability of aflatoxin incidence and severity. The incidence of aflatoxin was primarily relate1562d to average high humidity in July and average minimum temperature in August. The relevant variables in a second equation were the number of weeks exceeding 32 dg. C. for weekly maximum temperature, and the number of weeks in which average weekly high humidity exceeded 95 %. The severity of aflatoxin was related to July average maximum temperature, August average minimum temperature and July average high humi
