Abstract

In a field experiment the efficacy of some medicinal and aromatic plant species namely, Damsisa, Marigold, Marjoram and Peppermint as intercropping and Castor bean, Lantana and Wild mint as soil amendments either alone or combined with two biocides (Blight stop and Clean root) against Fusarium oxysporum f.sp. lycopersici-Meloidogyne incognita disease complex in tomatoplants (Hybrid 85) was studied. All treatments had a positive effect on the reduction of disease severity, population of the fungus in the soil and nematode parameters (no. of galls, egg masses, developmental stages, nematode population in soil and its reproduction rate) with significant increase in plant height and fruits yield at the end of experiment. Combined treatments between biocides and each of the tested plant species effectively enhanced the level of disease reduction compared to each single treatment. Blight stop treatment plus any plant species tested was the most effective in decreasing disease complex than combined treatments with Clean root. Treatment of tomato- marjoram intercropping combined with the biocide Blight stop followed by combined treatment between marjoram and the biocide Clean root and wild mint-amended soil combined with Blight stop treatment were the most effective in this concern. Although, intercropping of damsisa and peppermint with tomato plants reduced severity of disease complex but affected plant growth and fruits yield to the lowest value.
