Two greenhouse experiments were conducted on eggplant to assess the impact of compost tea derived from plant residues namely rice hull (RHC), rice straw (RSC), tomato (TC), potato (PC), citrus (CC), and guava(GC) as well as city waste (CWC) compost on eggplant biomass and reproduction of Meloidogyne incognita and Rotylenchulus reniformis. Screened composts were introduced to plants as drenching application. Results indicated that percentage of increase in total plant fresh weight of eggplant infected with such nematodeswere more pronounced (P<0.05) with compost teas of RSW. Drenching the soil with RHC (Rf=0.7) and PC (Rf=0.9) were also effective in suppressing densities of M. incognita as well as number of galls, and eggs/ root. However, population densities and fecundity of R. reniformis were significantly reduced following the introduction of GC. Only, total phenol showed remarkable increment in plants treated with PC, GC and RSC compared to untreated inoculated plants.
