Considering the importance of the tomato crop and the high costs for controlling Meloidogyne incognita with resistant cultivar or nematicides, it is necessary for the search of new alternatives to manage the root-knot disease. The homeopathy may be an alternative way of control, by inducing plant resistance. This study aimed to evaluate the influence of the homeopathic product Cina at dynamizations 12, 24, 50, 100, 200, and 400 CH (centesimal hahnemanian dilutions) on the number of root galls, eggs and second-stage juveniles (J 2 ) present in the roots of tomato and soil, as well as on the growth of tomato plants. The Cina demonstrated effectiveness in stimulating root development, once the results of root volume were higher in homeopathic treatments than those in the control. Cina 100 CH also favored the growth of the stalk diameter of the plants. However, the homeopathic product showed no nematostatic nor nematicide effects. The potentized Cina is capable to induce tomato growth besides the presence of M. incognita infecting the roots, with no nematotoxic effects.
