Interaction between the nematodes Heterodera cajani, Meloidogyne incognita, Rotylenchulus reniformis and the fungus Fusarium solani on cowpea plants

Abstract

Effects of concomitant inocula of H. cajani (Hc), M. incognita (M₂) and R. reniformis (Rr) on cowpeas showed that more eggs, L₂ and cysts were developed in cowpea roots in the H. cajani alone treatment than in the three nematode pathogen treatments. The final cyst population –being, increased with the increase of inoculated larvae is positively correlated with the larval inoculate level of H cajani. With the exception of the treatment 1000Hc+ 4000 Rr, statistical more H. cajani L₂ population were extracted from roots of the concomitant nematode treatments than from the H. cajani single inoculated treatment
