Effects of tillage regimes and herbicides onFusariumspecies associated with corn stalk rot

New agricultural practices in the Loess Plateau of China do not reduce colonisation by arbuscular mycorrhizal or root invading fungi and do not carry a yield penalty

“…Nearly all fungal species isolated from winter wheat root are pathogenic and some of them, such as Fusarium spp. and Rhizoctonia sp., cause serious root rot and aboveground diseases (Pankhurst et al 2002;Skoglund and Brown 1988). However, no disease symptoms were found in our study.…”

“…Soil-borne diseases caused by rootinvading fungi, such as R. solani and Fusarium spp., generate important reductions in crop yield worldwide (Skoglund and Brown 1988;Rovira 1986). These fungi can survive many years in soil and have a wide range of host plants, so that diseases caused by them are very difficult to control (Pankhurst et al 2002;Skoglund and Brown 1988). Tillage and residue management (including stubble retention and return of residues to the field) have been suggested to depress root rot disease caused by R. solani in some agricultural systems (Pankhurst et al 2002) but have contributed to an increase in disease severity in others (Roget 1995;Rovira 1986).…”

“…in disease-suppressive soils in South Australia (Rhizoctonia solani;Roget 1995;Rovira 1986) and in corn fields in Colorado, USA (Fusarium spp. ; Skoglund and Brown 1988). Soil-borne diseases caused by rootinvading fungi, such as R. solani and Fusarium spp., generate important reductions in crop yield worldwide (Skoglund and Brown 1988;Rovira 1986).…”

Biological detoxification of fungal toxins and its use in plant breeding, feed and food production

“…The severity of the problem is enhanced by introducing agricultural techniques that increase the infection pressure. The stimulatory effect of minimal tillage and wheat/corn succession on Fusarium blight, though sometimes obscured by weather conditions and other factors (Miller et al, 1998), is well established (Teich and Hamilton, 1985;Skoglund and Brown, 1988). In spite of this, minimal tillage practices are widely used for economic or ecological reasons.…”
