Polygalacturonase Production by Sclerotinia Sclerotiorum, Causal Agent of Canola Stem Rot: Parameter Optimization Using Taguchi Approach
Submerged culture conditions for polygalacturonase production by Sclerotinia sclerotiorum (MR5) were optimized by Taguchi orthogonal array experimental design methodology. This approach facilitates the study of interaction of a large number of variables spanned by factors and their settings with a small number of experiments leading to considerable saving in time and cost for the process optimi...

متن کاملEpidemiology / Épidémiologie Epidemiology of sclerotinia rot of carrot caused by Sclerotinia sclerotiorum
The epidemiology of sclerotinia rot of carrot was investigated on carrot ‘Cellobunch’ during 1999 and 2000 in Ontario. Apothecia were first detected in the crop in early August to mid-September, after the carrot canopy closed and after 7–11 days with soil matric potentials between –0.1 and –0.4 bars and soil temperatures between 14 and 23 °C. Ascospores were first detected in mid-July to mid-Au...
متن کاملBiocontrol traits and antagonistic potential of Bacillus amyloliquefaciens strain NJZJSB3 against Sclerotinia sclerotiorum, a causal agent of canola stem rot.
Bacillus amyloliquefaciens strain NJZJSB3 has shown antagonism of several phytopathogens in vitro, especially Sclerotinia sclerotiorum. Both the broth culture and cell suspension of strain NJZJSB3 could completely protect the detached leaves of canola (Brassica napus) from S. sclerotiorum infection. In pot experiments, the application of strain NJZJSB3 cell suspension (10(8) CFU/ml) decreased t...
متن کاملEfficacy of Micro-Nutrients, Fungicides and Bio-Agents against Sclerotinia Stem Rot (Sclerotinia sclerotiorum) of Indian Mustard
Sclerotinia sclerotiorum (Lib.) de Bary is a broad range fungal pathogen which attacks more than 500 species of higher plants (Boland and Hall, 1994; Saharan and Mehta, 2008; Sharma et al.,, 2015a). The pathogen can cause serious losses in yield and quality on numerous important field and vegetable crops (Purdy, 1979). Stem rot of Indian mustard caused by S. sclerotiorum (Lib.) de Bary has beco...
