The effect of abamectin (Streptomyces avermitilis, Abamax®) and plant activators (harpin and Lactobacillus acidiophilus) singly or in combination was tested against Meloidogyne incognita on tomato under controlled conditions. The experiment was established 5 days after transplanting of 35 days of tomatoes. ProAct Plus® (Harpin, 0.15 g/l), ISR-2000® (L. acidophilus, 1 ml/l) and Crop-Set® (L. acidophilus, 0.6 ml/l) were applied to the leaves by spraying, while Abamax® was applied to the soil. Nematode inoculation (1000 second juvenile larvae (J2)) was planned 72 hours after the first application of activators. The activators were applied to tomatoes 2 more times with 14 days intervals. After sixty days, plant height and weight, root height and wet weight, number of galls and egg masses, gall index, J2 soil density and lignification of leaves, stem and roots were evaluated. While the gall index was 4/0-5 index in plants treated only with nematodes, it was found to be 1.2/0-5 index in Abamax®. While 1.6 was found in Proact Plus®, 2.0 was detected in ISR2000® and Cropset®. No galls or egg masses were found in ProAct Plus®+Abamax®, ISR-2000®+Abamax® and Crop-Set®+Abamax®. The positive effect of abamectin alone on plant development was found to be higher than plant activators. Root wet weight increased significantly in Abamectin and plant activator combinations. Plant activators caused an increase in lignification and the highest level was found in Proact Plus®. Lignification was higher in combinations with Abamectin. The highest lignification was in Abamax®+Proact Plus®. The combinations of activators with abamectin may be a potential antagonism strategy against root knot nematodes.
