Plant Pathology Science

 Pomegranate is an important fruit crop which is attacked by several pests and pathogens. Diseases caused by nematodes are of economic importance. The root knot nematodes (Meloidogyne spp.) causing considerable yield losses in pomegranate.  Root knot nematodes are sedentary endoparasite that are basically parasites of the roots, produces knots on root which cause weak root function in the absorption and transfer of water and nutrient. Above ground symptoms include dwarfing the plants, yellowing and reduction of foliage, falling leaves and yield losses. Under favorable temperature and moisture, eggs are hatching and second stage pathogenic juveniles are released. The management strategies are including sanitation, construction of nursery in healthy areas, annual plowing of garden, drip irrigation, soil solarization, organic amendment of soil and strengthen the trees.
