ABSTRACT: Under conditions of stress, plants trigger defense mechanisms, not always effective in combating damages caused by external agents (noxas). Homeopathic preparations can contribute as tools which stimulate defense mechanisms when facing phytopathology agents. The study aimed to observe the effects produced by the homeopathic Sulphur on germination, rooting and increasing of soybean immunity (Glycine max), when exposed to fungal contamination. Preliminary study showed that the Sulphur 30CH medicine demonstrated an increase in Glycine max rooting. The experiment design in vases was completely randomized, with 3 replications and disposed on a 5 x 6 bifatorial arrangement, evaluating five cultivars of Glycine max, under the influence of Sulphur (0, 6CH, 9CH, 12CH, 30CH and 200CH). The stature of the plant, the length of the longest root, the fresh and dry masses of aerial parts and roots have been assessed. The results showed a positive response to treatment; some dynamizations incrementing the fresh and dry masses of aerial parts and roots, and there was a positive effect for the Mildew-infected soybean cultivarsin all the dynamizations.
