AuthorsI.K.A. Ibrahim and Z.A. Handoo
Abstract

The pathogenicity of root-knot nematode Meloidogyne incognita race 1(Mi1) and race 3 (Mi3) on rice (Oryza sativa L.) was studied in the greenhouse. Seventeen rice cultivars were tested for resistance to Mi1 and Mi3. The results showed that rice cvs Araby, Giza 159, Giza 170, Giza 171, Giza 172, Giza 177, Giza 178, Nahda, Sakha 101 and Sakha 102 were either susceptible or highly susceptible to Mi1. Rice cvs A95, IR1, IR22 and Japonica 47 were moderately susceptible to Mi1, whereas cvs IR28, IR459 and Philippini 24 were moderately resistant to Mi1. On the other hand, all the tested rice cultivars were either resistant or moderately resistant to Mi 3. Control of M. incognita race 1 on rice cv. Sakha 101 was studied in the greenhouse. Three tests were conducted to study the effects of soil treatment with some plant materials, stems of oyster mushroom (Pleurotus ostreatus), the biocontrol agent Bacillus thuringiensis, the bionematicide abamectin, and the nematicide fenamiphos on Mi 1 on rice cv. Sakha 101. All the applied control treatments were effective in reducing nematode infection on rice plants
