Abstract: A greenhouse experiment was conducted to determined the impact of threeorganic materials i.e. sesame grounded seeds and pigeon manure as pre-plantingapplications as well as salicylic acid as foliar spraying either alone or mixed withoxamyl at their half doses each on M. incognita infecting tomato plant cv. Alisacomparing with oxamyl at the recommended dose under greenhouse conditions(27±3oC). Pigeon manure alone or mixed with oxamyl at half doses overwhelmedother treatments in the increment values for total plant growth parameters andaccomplished the highest percentage reduction of final nematode population,(95.4%), number of galls (93.7%), and egg-masses (94.4%), respectively. It isinteresting to note that no significant deference between the three doubletreatments tested in plant length values that were amounted to 57.29, 57.29 and54.16% for pigeon, salicylic acid and sesame plus oxamyl each at their half dosescomparing to nematode alone. Nematode reproduction factors under the stress ofsesame grounded seeds, pigeon manure and salicylic acid solely or mixed withoxamyl at their half doses each in comparing with oxamyl were adversely affected.Such rates ranged between 0.07- 0.14 vs 2.41 for nematode alone. It was evidentthat N, P, K and OM concentrations were obviously reduced by nematode infection.All tested components specially pigeon manure plus oxamyl as pre-plantingapplication showed remarkable increase in N, P, K, and OM concentrationsexceeding those of nematode alone.
