The aim of this paper is to give a state of the art approach to pesticides in the cultivation of beans, as a practice where the main active ingredient is Imidacloprid. It is important to understand that the application of any pesticide a process of interaction between it and the average starts, until it ends its effect disappears. Some pesticides according to their structure and physicochemical characteristics persist in the environment, thereby fostering the accumulation mainly in water and soil, so it is important to know the art study concerning the prevalence of the pesticide Imidacloprid in the main bean crop. According to the objective proposed in the literature search, the analysis that was found in the prevalence of Imidacloprid, we find that the qualitative methods were devoted to the realization of the self in vegetables. Which it is allowed sable that there are no studies of toxicity of Imidacloprid in Ecuador, mainly in the bean crop which is where this pesticide is applied. Imidacloprid residues were found in samples of plant squash, eggplant and okra, here's why it concluded that a cause of evil in practice management pesticide. It is recommended that pesticide residues, especially pesticides used today are to be monitored within Ecuador, regularly, s. para determine pesticide residues in child primary products for human consumption.
