<em>Rhizoctonia solani</em> J.G. Kühn is a serious soilborne pathogen in chilli fields worldwide. This study examined the effect of biofumigation using arta (<em>Calligonum polygonoides </em>L.) and olive (<em>Olea europaea </em>L.) plant material on chilli growth and recovery of <em>R. solani</em> from chilli plants. The experiment was conducted under greenhouse conditions in potted soil amended with no plant material (control) or with plant material from <em>Calligonum and Olea </em>(olive leaves, or ash of olive leaves). Chilli was planted in the amended soils and inoculated with <em>R. solani</em>. Plant height, number of fruits , and frequency of recovery of <em>R. solani</em> from chilli were recorded. Soil amendment with <em>Calligonum</em> plant material resulted in the lowest frequency of recovery of <em>R. solani</em>. Moreover, <em>Calligonum</em> treatment increased dry mass and height of chilli plants compared to other treatments. Also, treatment with olive plant parts inhibited <em>R. solani</em> growth and enhanced growth of chilli compared to the control treatment. Thus, <em>C. polygonoides</em> and <em>O. europaea </em>are potental biofumigant plants to control <em>R. solani</em>.
