Interactions between the oomycete Pythium arrhenomanes and the rice root-knot nematode Meloidogyne graminicola in aerobic Asian rice varieties by Verbeek, R. E. M., Banaay, C. G. B., Sikder, M., De Waele, D., Vera Cruz, C.M., Gheysen, G., Höfte, M., Kyndt, Tina

“…The delay in establishment and development of M. graminicola becomes stronger with higher P. arrhenomanes infection pressure. Our data indicate that P. arrhenomanes antagonizes M. graminicola in the rice root and that the plant benefits from this antagonism as shown by the yield data, especially when either of the pathogens is present in high levels…”
