The pollen of Iva xanthiifolia can induce allergic diseases and it may become a serious source of allergens in Europe [d]. Recorded infesting sugarbeet fields in Serbia. In Hungary, encroaching Iva xanthifolia threatens spring-sown row crops, such as sunflower, maize and sugarbeet. It can also cause considerable damage to sunflower plantations in Hungary [1d].
