In this experiment five fungicides;Roveral, Rizolex, Vitavax, Benlate, and Cabtan  with  seven   concentertions  for   each one (0, 25, 50, 100, 200, 400, 800  ppm) were used to control Fusarium solani in the laboratory    and   in   greenhouse   on  local  varieties  of  beans  for    longitiudinal fungal growth were taken at determined period. Results indicated that fungal growth was inhabited after 192 hr from incubation at conc. 200 ppm of Rizolex, at 400 ppm of captan and Benalte and at 800 ppm from Roveral and vitavax. Significant differences were noted between periods, fungicides and concenterations . In the greenhous expirements three concentrations for each fungicide were used. Results indicated that Vitavax gave the lowest pre – and post emergence seed death, followed by Benalte , Rizolex captan ahd Roveral respectively, significant differences were noticed between the time and the treatments. Results indicated that fungicides and concentrations had different effects on root length, fresh and dry weight of vegetative and root growth.
