Studies were conducted in a glasshouse to assess the biocontrol potential of the culture filtrates of the antagonists namely Trichoderma viride Pers. ex. Fr., T. harzianum Rifai, Paecilomyces lilacinus (Thorn.) Samson, Pseudomonas fluorescens Migula and Bacillus subtilis (Cohn) as soil application against Heterodera cajani Koshy on blackgram. The culture filtrate of B. subtilis caused maximum reduction in cyst and juvenile population by 95.2 and 94.3 percent, respectively followed by P. fluorescens and P. lilacinus.

The culture filtrate of B. subtilis caused maximum reduction in cyst and juvenile population by 95.2 and 94.3 percent, respectively followed by P. fluorescens and P. lilacinus.
