Stem rot caused by Sclerotinia sclerotiorum in many important dicotyledonous crops, including oilseed rape (Brassica napus), is one of the most devastating fungal diseases and imposes huge yield loss each year worldwide. Currently, breeding for Sclerotinia resistance in B. napus, as in other crops, can only rely on germplasms with quantitative resistance genes. Thus, the identification of quant...

Sclerotinia stem rot (SSR), caused by sclerotiorum, is a devastating disease of oilseed rape that may cause significant yield losses if not controlled cultural management strategies and fungicide applications. Studies were conducted to evaluate the efficacy different group fungicides as well biopesticide, including azoxystrobin, boscalid, fludioxonil, prothioconazole, tebuconazole, azoxystrobin...

Sclerotinia stem and root rot, caused by sclerotiorum, is considered to be an important soil-borne disease of over 400 plant species, including a wide range species for agriculture. In vitro in vivo sensitivity S. sclerotiorum several commercial fungicides biofungicides was studied. The highest efficacy achieved boscalid (98%) fluopyram (80%), the lowest B. subtilis-based product (5%). isolate ...

Pseudomonas sp. DF41 is a biocontrol agent capable of suppressing Sclerotinia sclerotiorum-mediated stem rot of canola. Using transposon mutagenesis, we identified two mutants with greatly reduced antifungal (AF) activity. The first mutant had an insertion in gacS, forming part of the GacS/GacA regulatory system. The second mutation was in a gene involved in lipopeptide (LP) synthesis suggestin...

AIMS To establish the modes of action of the antagonistic fungal strain Clonostachys rosea BAFC3874 isolated from suppressive soils against Sclerotinia sclerotiorum and to determine its potential as a biocontrol agent. METHODS AND RESULTS The antagonistic activity of C. rosea BAFC3874 was determined in vitro by dual cultures. The strain effectively antagonized S. sclerotiorum in pot-grown let...

Three damaging soybean diseases, Sclerotinia stem rot caused by a fungus sclerotiorum (Lid.) de Bary, Phytophthora root sojae, and cyst nematode (Heterodera glycines Ichinohe), are destructive to growth yield cause huge economic losses. Biocontrol is an effective way control diseases with the advantage of being environmentally friendly sustainable. To date, few reviews have reported these three...
