There is an increasing demand for sustainable agricultural practices producing safe food. These farming technologies rely on techniques such as crop rotation, green manure; compost and biological pest control to maintain soil productivity and control pests. The use of manufactured fertilizers and pesticides, plant growth regulators, livestock antibiotics, food additives, and genetically modified organisms is excluded or strictly limited. However, in order to convert land previously used in common agricultural practice and prepare it for organic management practice, efficient technologies are needed. Furthermore, organic farmlands are exposed to dangerous xenobiotics through distinct pollution drift effects such as wind driven pesticide containing dusts and xenobiotic containing rains. From these compounds the most outstanding problems are related to the following two groups of pollutants: POP (Persistent Organic Pollutants) compounds (e.g. dioxin, DDT, HCH) and PAHs (Polycyclic Aromatic Hydrocarbons) (e.g. benzpyrene) which are recognized as being directly toxic to biota. Therefore a continuously detoxifying technology is needed in the course of organic production. Farmers running low-input agricultural production increasingly face with the problem of soil-borne pests. The key of pest control is establishing and maintaining the microbial community structure in a disease suppressive state. Organic agricultural production requires reliable pathogen management that in the past has been difficult to obtain. New approaches of the biological control may provide new tools for these farmers. Challenging these problems, the main objective is the development of an optimized, fungal-based product and technology which is able to the quick transformation of the problematic groups of xenobiotics to less toxic or nontoxic compounds in organic farmland soils, able to suppress plant pathogenic fungi in the rhizosphere and trigger the plant systemic acquired resistance system.
