The expressive increase in the production chain occurs together with the objective of producing food with lower levels of chemical residues and higher product quality. One of the natural mechanisms of plant defense, induced by eliciting activities, is the biosynthesis of phytoalexins, That are secondary metabolites produced by the plant at the site of infection and can be used for pest control. This work aimed to induce the production of phaseolin in common beans using eugenol as an elicitor, as it is already known for its fungicidal and bactericidal actions. The applied methodology was adapted and is based on chemical and analytical techniques aiming the phaseoline induction in the bean plant through the eugenol elicitor agent. Once induced, the phaseoline was extracted in ethanol ethanol and read on a 280 nm UV-VIS spectrophotometer. After the use of eugenol (0.3%) in the bean plant, the production of phaseolin was 4.22 times higher in this treatment when compared to the negative control (water) and 3.45 times higher in relation to the positive control (Bion®). According to the results obtained, it was confirmed that eugenol has an elective action on the bean plant, as it induced the production of phytoalexin phasolin.
