Pesticides alter water quality and affect stakeholders in Turbio River basin, Mexico. The aim of this study was to identify local practices and perceptions regarding the management of pesticides in San Francisco, Purísima del Rincón, and Manuel Doblado, municipalities of ​​Guanajuato. A cross-sectional survey was carried out with 69 agricultural workers, suppliers, and institutional representatives from September to November 2021. The results were analysed descriptively to identify the substances and impacts most frequently reported by stakeholders. The quantification of the impact on health and the environment for these substances was added. Insecticides like cypermethrin, lamda-cyhalothrin, chlorpyrifos, fenvalerate, and malathion, in addition to the herbicides topramezone, 2,4-D, glyphosate, and paraquat, were widely used. These were rated as low to moderately hazardous to health and high to very high hazardous to environment, according to the impact assessment results. Handling practices indicate that almost 50% of farm workers dose based on the label of products, 98% report that they protect themselves only with basic elements, and 48% report symptoms of acute toxicity (dizziness, vomiting, and intoxication), eye or skin irritation, and respiratory sensitivity. Future actions such as adequate training, safety and hygiene awareness, container disposal, and transfer of knowledge to local decision makers are necessary to reduce risks to health, to the environment, and to agricultural production.
