Submit ManuscriptTo assess the impact of Moringa and T. harzianum on managing Root Knot Nematode (M. incognita) in tomato and to ascertain the impact of combining Moringa and T. harzianum on (M. incognita) management in tomato, an experiment was carried out at the Ambo Agricultural Research Center in a greenhouse. Combinations of Moringa oleifera and T. harzianum were examined on plant parameters and M. incognita parameters on tomato plants at various concentrations of moringa plant extracts at(100%, 50%, 25%, 10%) and (1*104, 1*106, 1*108, 1*1010), respectively. The results showed that were significant variations (P0.05) on number of galls per plant, the number of egg masses per plant, final nematode population density per pot, and the reproduction factor among the treatments in terms of nematode population. Combined application of aqueous moringa plant extracts at S (100 percent) and T. harzianum at 1*1010spore/ml resulst showed the highest plant height 67.5 cm. The outcome showed those pots treated with aqueous moringa plant extracts S and T. harzianum 1*1010Spore/ml had the lowest mean reproduction factor (1.79) and population density (3588) compared to control. Pots treated with aqueous moringa plant extracts S/10 (10%) and T.harzianum 1*104Spore/ml had the highest mean reproduction factor and nematodes population density compared to the control. As a result, T. harzianum and M. oleifera could be utilized to combat M. incognita in the field. The findings of this study showed that test plants can lower nematode populations below economic thresholds and are easily accessible to farmers at no cost. Additional research is required to find new classes of bio-pesticides derived from natural plants that can take the place of the synthetic chemicals now in use.
