Chemical control of Rhizoctonia solani isolated from seed of local cultiver of bean (Phaseolus vulgaris)


  • Najah S. Zoology Department, Faculty of Science, Omar Al-Mukhtar University, Libya.



This study was carried out during the growing season 2005-2006 at Jabal AL-Akhder distric.Five fungicides were tested for control of Rhizoctonia solani which gave the highest infection level in pathological tests.

Chemical control was conducted in the laboratory using. five fungicides; Captan; Benlate; Vitavax; Rizolex and Rovral, in seven concentration 0, 25, 100, 200, 400, and 800ppm for eash fungicide and the means of the growth parameters were taken for four time Results showed inhibitior of fungal growth after 192 hours at the concentration of 25 ppm for benlat and 20 ppm for Rizolex, Rovral and Vitavax while it was 400 ppm with Captan .Significant differences were observed between fungicides, concentration and intervals interactions.

Result declasred the effects of treating P. Vulgaris local cultivar seeds with the last five fungicides for cotrolling R. Solanipre emergence seed death and post emergence seedling death were observed with Rizolex followed by Rovral, Benlate and Cabtan and finally Vetavax. significant differences were observed between intervals and between intervals and treatments.
