An overview of positive attributes of microbials depending on the organism: [...] colonize the roots and protect the crop during the entire growing season. Seed treatment increases the availability of plant nutrients in the root system [...] applied to the seed in a powder form or as a liquid. An even layer covers the whole seed. In this way, the beneficial ingredients are available to the seed when

  lesions on the stem. As the damage progresses, it causes darkening and rotting of the stem, resulting in the destruction of the cortex and the main root [...] resulting in longevity of more than five years in the soil, in a dry environment. Both the sclerotia and the mycelium are a source of inoculum, as the fungus [...] close to the surface of the stem. In favourable conditions, the sclerotia can germinate in two forms, hyphal or eruptive, causing infection in the plants

Finally, the whole plant wilts. Other symptoms are brown discolouration of the xylem vessels, which can be seen when the stems are [...] ascospores. In general, the life cycle of different Fusarium species is similar. Fusarium overwinters for many years in the soil, and on crop residues of infected

Conidia are produced on the infected leaves when [...] formed at the base of the leaf and the leaf sheath. They gradually extend and become brown and chlorotic and may merge.
