Impacting of Root-Knot Nematodes on Tomato: Current Status and Potential Horizons for Its Managing

Root-Knot Nematodes (Meloidogyne spp.) are very serious pathogen on tomato plants among the worldwide. They are widely distributed in soil and causes a highly economical losses for more than 5000 plant species. Therefore, many managements’ strategies are applicable to decrease their effectiveness such as resistant genotypes, soil solarisation and chemical control. Until now, chemical control is the most applied strategy for nematode management. Although nematicides are highly impacted for nematode suppression but environmentally not safety and very toxic. Consequently, several promising studies revealed that root-knot nematode (RKN) can inhibit nematode reproduction based on the susceptibility of their plant host. The plant effectors play a vital role during nematode infection and effect on plant response to nematode requirements. To understand well the relationship between nematode and their host, the molecular and immunolocalization methods illustrated some proteins which are expressed by plant genes involved in plant–nematode interaction. This chapter will focus on the latest status and future perspectives for nematode management.
