Temperature, water availability and light are key climatic factors influencing the production of Fusarium. In terms of manipulating environmental conditions to control Fusarium spp. diseases, adjustment of soil temperature and moisture has been successfully applied in many countries (Katan 1981; Doohan et al. 2003). Although zearalenone is ubiquitous and toxic, it globally presents a potential danger for animal and human health only when it is absorbed in high amounts or over a long period of exposure (Zinedine et al. 2007). Small amounts of zearalenone act as stimulating factors for plant development, and can serve as plant hormone in induction of physiological processes. Thus, low zearalennone concentration in growth media may be useful to stimulate development of crops and to accelerate the flowering of winter plants, which can be an important factor in agriculture production in changing environmental conditions. A particularly interesting question for future research is the possibility of determining the optimal zearalenone concentration in soil (and in crops) to balance the toxic and favourable action of this substance on both plant development and animal health.
