Abstract

  This study was conducted to evaluate an integration control strategy in controlling of tomato root knot nematodesby using resistant hybrids, the biological pesticide Verox, Nano-zinc oxide [ZnO NPs] and the chemical pesticide Velum under laboratory and field conditions. The results of the biocidal Verox at concentration of 2000 parts per million and ZnO-NPs at concentration of 4000 parts per million showed a significant decrease in the hatching of nematode eggs at a rate of 94.67 and 87.34%, respectively. compared to the untreated control treatment However The use of 400 ppm, 2000 ppm, and 4000 ppm of the nematicidal Velum prime reached 100%. On the other hands cultivars of tomato plants Samar , Meyameya and Maysaloun, significantly reduced the formation of root nodes and the level of infestation with caecilians compared to the control treatment. Maysaloun cultivar was the best among the other cultivars with a rate of root nodule formation of 0.14 and infection rate of 0.09.
