Table 5 Percentages of reduction of number of the root-knot nematode, Meloidogyne incognita infecting cowpea, number of galls and percentages of increase in number of bacterial nodules as affected by three culture filtrates from Beauveria bassiana, Metarhiziam aniisopliae, and Paecilomyces lilacinus

From: Evaluation of the fungal activity of Beauveria bassiana, Metarhizium anisopliae and Paecilomyces lilacinus as biocontrol agents against root-knot nematode, Meloidogyne incognita on cowpea
