Description Heterodera cajani is an important nematode pest of pegeonpea (Cajanus cajan (L.) Millsp.) in India. Forty-one H. cajani infested pegeonpea fields and H. cajani cultures maintained on pigeonpea at the ICRISAT Asia Center, Andhra Pradesh, were examined for presence of natural parasites of the nematode. The fungi Cephalosporium spp., Fusarium solani, Fusarium spp., Glomus spp., and gram positive bacterium, Pasteuria penetrans were found in cysts. Fusarium solani was the most commonly occurring fungus in eggs of H. cajani. On water agar, F. solani infected 70% of eggs in egg sacs. The numbers of eggs were reduced by 45–60% in presence of the fungus in greenhouse tests. Growth of pigeonpea cultivar ICPL 87 in H. cajani infested soil was improved by the presence of F. solani. The nematode reproduced in greater numbers in infested soil treated with 0.2% benomyl than in soil naturally infested with the nematode and the fungus but not treated with benomyl. The F. solani isolates recovered from H. cajani did not infect pigeonpea plants and were effective in suppressing H. cajani under natural conditions.
