Pomegranate (Punica granatum L.) is one of the important fruit crops, nowadays is highly threatened by the wilt caused by Ceratocystis fimbriata. Eleven bioagents were evaluated in vitro against Ceratocystis fimbriata. Among the bio agents tested, Trichoderma harzianum, Trichoderma isolate 1 and Trichoderma isolate 5 recorded the maximum percent inhibition of mycelial growth (100%). It was found significantly superior to the rest of the bioagents tested. This was followed by Trichoderma isolate 4, Trichoderma virens, Trichoderma isolate 2 and Pseudomonas fluorescens. Whereas, the minimum parasitic activity was noticed in case of Pseudomonas putida (43.12%), Paecilomyces lilacinus (44.98%), Trichoderma isolate 3 (48.94%) and Bacillus subtilis (55.00%).
