Özet:

 The root-knot nematode RKN, Meloidogyne incognita is one of the most widespread and economically damaging plant-parasitic nematodes PPNs. Due to the environmental drawbacks of synthetic nematicides, biological control agents offer a more sustainable alternative for nematode management. The present study aimed to investigate the efficacy of a bioproduct derived from Trichoderma harzianum Rifai Strain T22 in controlling M. incognita in tomato plants, utilising varying doses 30 g da-1, 40 g da-1, 50 g da-1. Additionally, the impact of this bioproduct on tomato development was examined. Abamectin treatment demonstrated the highest efficacy, achieving reductions of 67.28 in the root-gall index, 89.85 in the population of second-stage juveniles J2, and 81.28 in the number of egg masses, resulting in a reproduction factor RF of 0.83. The bioproduct at a dosage of 50 g da¹ resulted in a 30.17 reduction in the root-gall index, a 43.28 reduction in the population of J2, a 37.26 reduction in egg masses, and a RF of 4.65. In contrast, the bioproduct at 30 g da¹ was less effective, yielding reductions of 11.47 in the root-gall index, 22.76 in J2, 16.83 in egg masses, and an RF of 6.33, respectively. The bioproduct applications also significantly enhanced tomato growth, resulting in the highest increases of 22.73 in shoot length, 45.19 in root length, and 19.80 in shoot weight at a rate of 50 g da¹. In conclusion, T. harzianum-based bioproducts are effective for the integrated management of M. incognita, but future research should focus on optimising doses and testing different treatment combinations to further improve efficacy.
