Interactions of Fusarium species during prepenetration development

► Fusarium spp. have preferred temperature for germination and germ tube growth. ► Fusarium spp. germinate with more than one germ tube per conidium cell. ► Presence of nutrients fastens conidia germination and germ tube growth of Fusarium spp. ► Interactions among Fusarium spp. during early stages of growth are competitive. ► Macroconidia producing fusaria are more competitive than microconidia producers.
