Pseudomonas syringae pv. Tomato causes bacterial speck in tomato crops, causing stunted growth, late fruit ripening, and yield losses. Pesticides are used to control this phytopathogen, which have been reported to be a source of soil contamination. Because the use of pesticides has increased and, with it, the negative impact, it is necessary to look for efficient and environmentally friendly alternatives. Electrolyzed water is an alternative to the use of pesticides as it has been shown to have an antimicrobial effect. It is produced by electrolysis of dilute solutions of NaCl in an electrolysis cell. The present work evaluated the effect of acidic and alkaline electrolyzed water on PstDC3000 cultures. The experiment was conducted in the agrobiotechnology and electrochemistry laboratory of the Technological Institute of Tepic in 2020. Treatments with acidic and alkaline electrolyzed water were applied for 1, 3, and 6 minutes. The results show total inhibition of PstDC3000 with acidic electrolyzed water treatment at minute 01. On the other hand, treatment with acidic electrolyzed water managed to reduce 26.9%, 42.16%, and 58.53% CFU ml-1 at minutes 1, 3, and 6, respectively. Finally, it was concluded that electrolyzed water affects the growth of PstDC3000 and that pH is a factor that influences its bactericidal activity.
