Girasoil is a corroborant obtained from sunflower seeds (Helianthus annus) through a mechanical pressing and subsequent filtration and dilution in water (emulsion) with high content of vitamin E. The raw material used has been obtained without the use of genetic modification techniques or genetically modified organism (OGM free). No chemical synthesis processes were involved in the production. Girasoil improves plant resistance against biotic and abiotic stress (Oidium neolycopersici). It reduces fungal growth and spore germination on treated surfaces. Besides, it modifies and devitalizes the
structure of the cell membrane. It has a fungistatic action carried out in a preventive way, blocking the growth of pathogenic fungi. It also acts against insect vectors of viruses and spiders.
