“…Good progress has been made towards controlling clubroot through the use of chemicals (Cheah 1995;Cheah et al 1999), disease-resistant cultivars (Falloon et al 1997) and biological control (Cheah et al 2000a). We have also identified Brassica spp.…”

“…Streptomyces sp. (S99) which has been shown to give significant control of clubroot (Cheah et al 2000a) was also included in this trial. This isolate was cultured and grown in autoclaved crush maize in plastic bags for 4 weeks at 22°C.…”

Two glasshouse experiments and a field trial were carried out to evaluate the potential of brassica crops which contain high levels of glucosinolates for control of clubroot of brassicas Brassica rapa crops were grown for about 70 days in a field which was infested with Plasmodiophora brassicae In the first glasshouse experiment the leaf and stem of the plants were harvested chopped into small pieces and mixed with clubrootinfested soil in punnets Chinese cabbage seedlings were then transplanted into the punnets In the second glasshouse experiment soil samples were taken in punnets from plots where the B rapa crops had been rotary hoed and left to decompose for about three weeks Chinese cabbage seedlings were transplanted into the punnets In both experiments B rapatreated soil reduced (P

“…Several methods using chemical agents, agricultural pesticides, or antagonistic microbes have been developed for the control of clubroot disease (Datnoff et al, 1987;Cheah et al, 2000;Yeoung et al, 2003); however, as they entail chemical control every cropping season, these methods are costly and require a lot of manpower. Moreover, the effect of the control lasts only during the controlled season, allowing the disease to recur upon successive cropping.…”

“…Several strategies have been developed to reduce clubroot damage in the field. Among those are crop rotation with nonbrassica crops for at least 5 years, application of agricultural lime or soil amendments to raise soil pH above 7.2 (Dixon, 2009;Donald et al, 2006;OMAFRA, 2010b) improved drainage and avoiding production of susceptible crops on poorly drained sites (OMAFRA, 2010b), application of fungicides at seeding (Naiki and Dixon, 1987;OMAFRA, 2010b), use of biocontrol agents (Cheah et al, 2000(Cheah et al, , 2001and use of resistant cultivars. Synthetic fungicides and biofungicides are used in various parts of the world for clubroot management (Mitani et al, 2003;Suzuki et al, 1995), but only pentachloronitrobenzene (Quintozene 75 WP; AMVAC Chemical Corp., Newport Beach, CA) and fluazinam (Allegro 500F; ISK Biosciences Corp., Concord, OH) are registered for management of clubroot on brassicae vegetable crops in Canada (Howard et al, 2010;OMAFRA, 2010b).…”

Field trials were conducted to evaluate resistance to clubroot (Plasmodiophora brassicae, pathotype 6) in green cabbage (Brassica oleracea var. capitata) and napa cabbage (Brassica rapa ssp. pekinensis) at sites in southern Ontario in 2009 and 2010. The reaction of green cabbage cultivars Kilaton, Tekila, Kilaxy, and Kilaherb and the commercial standard cultivars, Bronco or Atlantis, were evaluated on organic (two site-years) and mineral soils (two site-years) that were naturally infested with the clubroot pathogen. In addition, fluazinam fungicide was drench applied to one treatment of the commercial standard cultivar immediately after transplanting. The napa cabbage cultivars Yuki, Deneko, Bilko, and Mirako (in 2009) and Emiko, Mirako, Yuki, and China Gold (in 2010) were evaluated only on organic soils (two site-years). At harvest, the roots of each plant were assessed for clubroot incidence and severity. Also, plant and head characteristics of the resistant green cabbage cultivars were evaluated at one site in 2010. The green cabbage cultivars Kilaton, Tekila, Kilaxy, and Kilaherb were resistant to pathotype 6 (0% to 3.8% incidence), but ‘Bronco’ was susceptible (64% to 100% incidence). Application of fluazinam reduced clubroot severity on ‘Bronco’ by 6% at one of three sites. Resistance was more effective in reducing clubroot than application of fluazinam. Plant and head characteristics of the resistant cultivars were similar to those of ‘Bronco’ treated with fluazinam. Napa cabbage cultivars Yuki, Deneko, Bilko, Emiko, and China Gold were resistant to clubroot (0% to 13% incidence), and ‘Mirako’ was highly susceptible (87% to 92% incidence). We conclude that the clubroot resistance available in several cultivars of green and napa cabbage was effective against P. brassicae pathotype 6.
