This study, which deals with seed and soil borne plant pathogens and compost, will be a source for isolating biocontrol actinomycetes. The aim of this study was to isolate potential antagonists from different composts and examine their activity against seed and soil borne fungal pathogens with special emphasis on controlling fusarium wilt of tomato. In addition, primary screening of potent isolate was performed under in vitro condition; further secondary screening under green house conditions was also performed for the control of fusarium wilt
