Investigation of chemical and biological fighting possibilities of tomato bacterial wild disease

Bacterial Wilt Disease caused by Clavibacter michiganensis subsp. michiganensis causes significant crop losses in tomato plants in economic terms. In this master's study, environmentally friendly microbial fertilizers (SS-Stomafix, Bio-Ag and SS-Super Root), two disinfectants (chlorine dioxide and hydrogen peroxide) and a licensed copper preparation in tomato were used in Kocide (35% copper hydroxide equivalent to metallic copper) in this disease control. The suppressive effect on tomato plants was investigated with a pot experiment in a glass greenhouse. In addition, the effect of these preparations on the total bacterial flora in tomato green parts was also revealed. Among these applications, Bio-Ag, a biological control product containing 14 different types of antagonist bacteria, was determined to be the most effective and most successful application by suppressing Bacterial Wilt Disease with a 51.07% rate. Following this, SS-Super Roots and SS-Stomafix applications were determined as other effective applications and the disease was suppressed by 35.70% and 35.17%, respectively. Copper hydroxide, chlorine dioxide and hydrogen peroxide applications were evaluated as ineffective applications since they were in the same group as the positive control. As a result, it was determined that microbial fertilizers have the potential to be used in the biological control of Bacterial Wilt Disease in tomato plants.
