Abstract :The aim of the study was to investigate the effects of different Abamectin formulations and concentrations (Abamectin 18 g L-1 EW, Abamectin 20 g L-1 SC and Abamectin 50 g L-1 SC) licensed in Türkiye on the suppression of Meloidogyne incognita infection on tomato and cucumber under climate chamber conditions. Tomato and cucumber seedlings were transplanted after soil application of 0.1 mL, 0.2 mL and 0.08 mL/30 mL concentrations of Abamectin 18 EW, Abamectin 20 SC and Abamectin 50 SC, respectively and inoculated. Sixty days later, the study was evaluated. The nematicidal activity of Abamectin varied depending on the formulation and concentration. Abamectin 50 SC, Abamectin 18 EW and Abamectin 20 SC applications suppressed gall formation by 100%, 78% and 16% in tomato and 100%, 75% and 19% in cucumber, respectively. EW formulation showed lower suppressive effect than SC formulation but higher suppressive effect than 20 SC formulation. Although both were SC formulations, significant differences were found in their nematicidal effects (p≤0.05). The highest suppressive effect in tomato and cucumber was observed in Abamectin 50 g L-1 SC application and it was determined that it had a positive effect on plant and root wet weight in tomato. It is important to conduct more detailed studies on formulation types and concentrations for Abamectin, an active ingredient used as an alternative against root-knot nematodes.
