SDHI fungicides bind to the SDH complex and block the transport of these electrons, energy production is curtailed, and fungal growth is arrested (4). However, reduced sensitivity to SDHI fungicides has been reported for several pathogens in different cropping systems, including Botrytis cinerea in various fruit crops (Yin et al., 2011 and Veloukas et al., 2011); Alternaria spp. All the life stages of sting nematode (eggs, juveniles and adults) reside in the soil.
