Abstract: Plant protection is extensively engaged in conversation with organic growers both National and world level, yet organic agriculture faces the same plant-parasitic nematodes (PPNs) issues as conventional farming. The main motto and basis of organic agricultural system is to maintain the health of soil and its food web. Along with maintaining soil fertility, the farmers also want to maintain good microbial population required for nutrient recycling. This makes the application of organic matter in the form of composts and manures that will decrease the pest populations and incorporation of cultural practices like crop rotations. It also helps in addition of nutrients to the soil. The ultimate goal of organic agriculture is to improve the plant health; hence amending the soil with organic matter is the basic factor for soil ecosystem management, which directly or indirectly increases the crop yields. In organic farming systems, nematodes are becoming a hindrance in the profitable productions and it is very difficult to control in these systems, as chemicals are not supposed to be employ. Worldwide estimates of crop losses are about 12.3 % annually of food and fiber, due to nematodes. Different studies had conducted on organic and conventional farming systems. It has proved that genera of plant parasitic nematodes attacking organic farming are similar to that in conventional farming. Such as, root knot (Meloidogyne spp.), cyst (Heterodera and Globodera spp.), and reniform nematode (Rotylenchulus reniformis). Therefore, in this review article, we discussed different management strategies for PPN management in organic farming.
