Effect of rotation on colonization of field stubble by Fusarium species
This study identified Fusarium spp. naturally occurring on field stubble. Throughout the 4 years of sampling, seven Fusarium species were isolated from crop stubble. In 2002 and 2003 only the stubble of foundation crops of wheat and oat were colonized by Fusarium spp; low levels were isolated from pea and canola stubble in 2005 and 2006. No consistent pattern of colonisation was observed, suggesting that airborne inoculum, susceptibility of wheat to FHB, and favorable environmental conditions are important factors in epidemics.
