Abstract
A pot experiment was conducted to evaluate the effect of applying copper oxychloride at a rate of 100 ppm and elemental sulphur at a rate of 100 kg/ feddan as a fungicides and/or Rhizobium inoculation for controlling faba bean root rot disease caused by Rhizoctonia solani and Fusarium solani. Nodulation, growth and N-percentage of faba bean shoots were also evaluated. The results were as follows:
In soil infected with Rhizoctonia application of the fungicides alone or in combination with Rhizobium inoculation increased seedling emergence compared to that infected with Rhizoctonia only. Infection of faba bean with Fusarium showed lower emergence percentage compared to soil infected with Rhizoctonai. Copper oxychloride or sulphur had negative effect on seedling emergence for controlling faba bean root rot caused by Fusarium solani. The most effective treatment in reducing infection % caused by Rhizoctonia solani was recorded in soil treated with copper oxychloride or elemental sulphur. RhizobiumInoculationin soil infected with Rhizoctonia solani or Fusarium solanidecreased significantly infection percentage. Application of copper oxychloride or combination of Rhizobium and copper oxychloride had no effect on the infection % with Fusarium solani. In faba bean plants infected with Rhizoctonia solani, application of copper oxychloride or sulphur with or without Rhizobium inoculation had no effect on nodulation status.
Concerning to the effect of Fusarium solani on nodulation status, the results indicated that infection with Fusarium had an inhibitory effect on the nodulation of faba bean even in the presence of the fungicides. There was a significant increase in dry weight of shoots in soil infected with Rhizoctonia solani and treated with copper oxychloride compared to control plants. Rhizobium inoculation also increased significantly dry weight of faba bean shoots. Application of the fungicides had no effect on dry weight of shoots in soil infected with Fusarium solani.
