Abstract: One of the phytosanitary problems limiting the production of the tomato crop (Solanum lycopersicum) at a global and national level is vascular wilting, which causes economic losses to the producer of up to 60%.Given the importance of this disease, the objectives of this study were to identify the causal agent of tomato vascular wilt and to find the effective chemical and biorational product for control under in vitro conditions.Samples of tomato plant stems were collected in the valley ofParacuaro, the causal agent was isolated and identified macroscopically and microscopically.For the in vitro tests, the treatments wereAzoxystrobin, Folpet, Thiabendazole, Benomyl, Mancozeb, Copper Octanoate, Larrea tridentata and a control, three doses of each treatment were evaluated: 100, 500 and 1000 ppm, in a completely randomized design with four repetitions.The causal agent was identified as Fusarium oxysporum f. sp.lycopersici (Fol).The determination of the special form and race of F. oxysporum was through the use of differential tomato plants (S. lycopersicum), which was identified as race 3 of Fol.In the bioassays, the best treatments were: Folpet, Tiabendazol and Benomyl in the three doses used (100, 500 and 1000 ppm) and Mancozeb and Folpet only in the medium and high doses (500 and 1000 ppm), statistically significant.
