Organic Additives and Their Role in the Phytoparasitic Nematodes Management

Application of organic additives is an agricultural strategy for improving the physicochemical properties of the soil, the temperature and humidity conditions, soil structure which are valuable for plant development. Soil amendments like animal and green compost, undecomposed or deteriorated materials, plant extracts, essential oils, oil cakes and chitin, etc. are examples of organic additives. Plant parasitic nematodes cause greater damage to plants health. The application of organic additives is markedly important and can be used in the control of this tiny pest. PPN can survive in wide range of soil and multiply and incite significant losses to various crops. Also, organic additives may improve the soil conditions, such as temperature, pH, salinity, oxygen, etc. which are unsuitable for nematode multiplication. The outcome relies on many factors, such as the material used, the rate of use, the processing/composting of materials, agronomic practices, crop rotation and soil type, the climate, and other environmental factors.
