Plant parasitic nematodes are obligate agricultural organisms that cause significant economic losses and damage to many plant species worldwide. Most of the plant parasitic nematodes can damage the roots of their hosts, while a very small number of them can damage the above-ground parts of plants such as leaves, flowers or seed. As a result of the feeding of plant parasitic nematodes on the roots, the ability of the plant to adsorb water and nutrients decreases. They damage the host plant by causing wounds on the plant roots and some microbial diseases with the stylet they use during feeding, by forming brown spots on the root and swelling or rotting of the tubers on the above-ground parts of the plant. Plant nutrients have an important place to overcome the damage of plant parasitic nematodes. Nutrients can reduce or increase nematode populations. This effect depends on the nutrient element and the source of nutrient used. Plant nutrition and plant parasitic nematodes interaction have generally shown that nitrogen, phosphorus, and potassium. The form in which the nutrient (ammonium or nitrate) is present has a greater influence on the severity of nematode attack than the amount of nitrogen present. It is stated that the use of ammonium is better than nitrate in reducing the plant parasitic nematode population. Phosphorus has direct microbial activity against pathogens as well as the ability to stimulate plant defense mechanisms through the production of phytoalexins. Adequate plant nutrition with potassium is thought to reduce disease occurrence due to increased resistance to the penetration and development of pathogens. A balanced application of macro and micro nutrients to the soil is the best way to ensure that the plant can withstand the damage caused by nematodes. In this study, the information obtained about the effects of the use of some plant nutrients in fertilization against plant parasitic nematodes has been reviewed.
