Secondary metabolite produced in some plants can provoke alterations in the development of other plants or even other organisms. The aim of this paper was to identify possible allelopathic effects and biologic control of Achatina fulica Bowdich with aqueous extracts of Morus rubra L. leaves. For obtaining the aqueous extract, we used previously dried leaves in concentration of 1g 10 mL-1. Five concentrations of each aqueous extract were tested (10, 30, 50, 70 and 100%) and compared to control (0.0%), distilled water. The aqueous extracts of Morus rubra showed up allelopathic potentialities on the seed germination and in the growth of the shoot and the root system of the tested species, considering that the reduction in the germination and initial growth increased with the rising of the aqueous extracts concentrations used and, in the biologic control, only in the final mass of A. fulica. The results indicated the existence of allelopathic effect, but not molluscicide of M. rubra.
