Root knot nematode infections promoted by agricultural practice modifications in Vietnam and the impacts on rice production

In this study, we analyzed the reasons that could explain the unusual proliferation of PPN and its observed impacts on rice in Hai Duong Province, Vietnam. Three main hypotheses were tested: (i) A pest (nematode) highly aggressive to rice was emerging, (ii) Farmers used rice genotypes highly susceptible to nematode infections, and (iii) Modification of the farmer practices lead to the proliferation of the pest.
