The effects of paclobutrazol (PBZ) on growth, yield and anatomical structure of peanut plant infected with pod rot pathogens were investigated.  Treatments with PBZ at 250 and 500 ppm decreased plant height but increased shoot dry weight, number of branches and pegs per plant, 100 pod weight (g) and 100 seed weight (g).  Soil infested with either Fusarium solani or Rhizoctonia solani reduced all above mentioned parameters.  R. solani was more virulent than F. solani on plant growth and yield.  Treatment with PBZ at 250 and 500 ppm partially reduced the injurious effect of soil infested with either F. solani  or R. solani.  PBZ at high concentration (500 ppm) was more effective in this respect. Anatomically, the most striking anatomical changes occurred in the infected stems and carpophore with R. Solani are complete destruction of the epidermis, severe plasmolysis in the cortex followed by hydrolysis or dissolution of cell components and degradation of the primary cell walls leading to cell separation and some area of cortex tissue.  In addition, dissolution and degradation of cell components accompanied with breakdown and separation were found in some regions of pod shell and the cotyledons.
