Abstract Chilli fruits are commonly contaminated by Eurotimycetes fungus Aspergillus sp. Eurotiales Trichomaceae. This fungus produced white to lime green mycelium yellowish to green conidia which size is around 340.82661549. This study was carried out to investigate the effect of Aspergillus sp. on chilli seed germination. The seeds of the chilli variety MI green were obtained from DATC Jaffna for using this experiment. Chilli seeds were treated with Aspergillus sp. Trichoderma viride Aspergillus sp. Trichoderma viride Aspergillus sp. Neem extract and distilled water as control. Highest germination percentage were observed in T5 suspension of T.viride as 73 followed by 65 germination from T1 distilled water 44 from T3 suspension of Aspergillus sp. and T.viride then T4 suspension of Aspergillus sp. and neem leaf extract and T2 suspension of Aspergillus sp. showed the germination as 30 and 20 respectively. The growth inhibition percentage of Aspergillus sp. in presence of T. viride and T. harzianum were calculated by dual culture over control. The percent inhibition of radial growth of Aspergillus sp. was 55.35 by T. viride and 50.25 by T .harzianum in seven days after inoculation. Results show that T.viride was superior to T.harzianum in restricting the growth of Aspergillus sp. on dual culture in PDA.
