Abstract:
... Major studies on root knot nematode (Meloidogyne incognita) tend to focus on the nematode alone, but with not much attention to its synergistic association with bacterial or fungal pathogens co-inhabiting the crop rhizosphere. Nematodes pave the way for easy entry of these pathogens inside the host roots, forming a disease complex that causes enormous yield loss. Greater knowledge on the interacti ...

Abstract:
... Correct identification of species and pathotypes is must for eradication of potato cyst nematodes (PCN). The identification of PCN species after completing the life cycle is very difficult because it is based on morphological and morphometrical characteristics. Genetically different populations of PCN are morphologically same and differentiated based on the host differential study. Later on these ...

Abstract:
... Root knot nematode (Meloidogyne incognita) and soft rot bacterium Pectobacterium carotovorum subsp. carotovorum are major pathogens of carrot (Daucus carota) throughout the world, reducing both quality and quantity of marketable yield. Bacillus subtilis IIHR BS-2, a potential biocontrol agent, was evaluated against the nematode-bacterium disease complex in carrot under in vitro and field condition ...
