Volatilization represents an important transport process of pesticides for the environment. The clomazone physico-chemical properties indicate that molecule has the potential of volatilization. Therefore, for this study two experiments were carried with the objective of evaluating the species susceptibility: cucumber, melon, corn, sorghum and rice to different formulations of the herbicide clomazone in the vapor-phase. Glass boxes were used with the presence of clomazone formulations and plant species. The formulations used were Gamit 360 CS®, Gamit 500 EC® and Gamit Star®. As a main result it was conclude that among the species that were tested, independent of the formulation used, the lowest tolerance to clomazone herbicide in the vapor phase was sorghum, followed by corn and rice.
