Table 3 Effect of dry powder plant materials on M. incognita parameters and Rhizobium bacterial nodules number in pea roots system in pots, under greenhouse conditions

From: Application of dry powders of six plant species, as soil amendments, for controlling Fusarium solani and Meloidogyne incognita on pea in pots
