Abstract: Abstract Agronomy is seriously stuck by pest and diseases; as a corollary, massive quantities of synthetic pesticides are used in agriculture with many harmful effects of non-target entities. This study planned to rate pesticide risks to earthworms using pesticide risks in the tropics to man, environment and trade (PRIMET), a pesticide risk model in the mono-modal equatorial agroecological zone of Cameroon: the case of the Tiko plain along the Cameroon coastal line. Data on pesticide application scheme, pesticide persistence in the soil (DT50soil) and pesticide ecotoxicological properties (LC50 and NOEC) were gathered and inputted one after the other into PRIMET to find the predicted exposure concentration (PEC), no effect concentration (NEC) and exposure toxicity ratio (ETR = PEC/NEC). For ETR 100, there is a Definite Risk. For acute risk, independent on the pesticide category, the majority (91%) of pesticides were predicted to pose “no risk” to earthworms. In the chronic risk category, more pesticides were predicted to exhibit risk as compared to acute risk. The insecticide category had significantly higher (p
