Test the Efficiency of Magnesium Oxide Nanoparticles in Rhizoctonia Solani Fungus Control in Eggplant

This experiment was carried out at mycotoxin laboratory, plant protection Department, College of Agriculture to test pathological ability of Rhizoctonia solani fungus on eggplant and study efficiency of magnesium oxide nanoparticles to control of the pathological fungus R. solani in the culture media PDA at laboratory. The results showed that R. solani pathological fungus isolation gave high rate infection on eggplant seeds compared with the control sample ( without fungus addition) where the rate of infection by the fungus (in germination index) in which the germination ratio without fungus presence was 97.33 % and it was with fungus treatment 12 %. The results showed also effect of MgO nanoparticles in inhibition of the pathological R. solani fungus at 1 %, 2 % and 3 % compared with the control sample, and the inhibition rates were 96.33 %, 100 % and 100 % respectively where the MgO nanoparticles affected greatly and reached to 100 % in the pathological R. solani fungus inhibition on eggplant seeds.
