This study aimed to evaluate the effect of new alternatives for the control of tomato bacterial spot, with the use of sanitizing chlorine dioxide base, a biological formulated consisting of Bacillus subtilis and Paenibacillus lentimorbus and field covers phosphite. The test was conducted in the experimental area of the IF Goiano Campus Morrinhos using seedlings of hybrid BRS Seine. The experimental design was a randomized block design with four replications for each treatment for the evaluations were used the 10 central plants useful line. The experimental plot consisted of three simple lines of 5 m in length. The start of applications occurred within 14 days after transplanting with pressurized spray to CO2 with a flow rate of 300L ha-1, totaling 13 applications with an interval of 7 days of each other. The applications were carried out in isolated, combined and jointly with the chlorine dioxide product base, organic phosphite formulated and copper. The plants were inoculated with the bacterial suspension (Xanthomonas gardneri) at a concentration of 5x108 cfu / ml. Evaluations have begun to be carried out 7 days after inoculation accounting in total 8 reviews. Rotational chlorine dioxide or combined with phosphite copper and biological formulated alone are shown effective in controlling tomato bacterial spot. Thus, it is possible that they can compose a management program of the disease.
