Efficacy Testing of Seed Treatments with Isotianil and HiCFU against Clubroot Disease
Clubroot disease, caused by the protist pathogen Plasmodiophora brassicae is an emerging threat to cruciferous crops including oilseed rape (Brassica napus L.). Most of the current commercial rapeseed cultivars are highly susceptible. The pathogen builds up rapidly on susceptible crops and can also persist in soils as resting spores for more than 20 years when a suitable host is absent. Effective practical control options despite resistant cultivars are currently still lacking. In greenhouse trials over an experimental period of three years different concentrations and combinations of two biocontrol agents were investigated for their efficacy to reduce clubroot on different oilseed rape hybrids as well as different isolates of P. brassicae.
