Disease control in oilseed rape: Current insights and perspectives for next‐generation integrated pest management

Pest Management Science, EarlyView.
Winter oilseed rape in Europe suffers frequent pathogen losses. This review outlines key integrated pest management (IPM) strategies, rotation, residue and tillage management, optimized sowing, resistance, and targeted fungicides supported by forecasting.

ABA Is Required for Leptosphaeria maculans Resistance via ABI1- and ABI4-Dependent Signaling

Molecular Plant-Microbe Interactions, 2007
Abscisic acid (ABA) is a defense hormone with influence on callose-dependent and -independent resistance against Leptosphaeria maculans acting in the RLM1Col pathway.

Characterization of sirodesmins isolated from the phytopathogenic fungus Leptosphaeria maculans [PDF]

Journal of the Serbian Chemical Society, 2012
Pathogenicity of phytopathogenic fungi is accociated with phytotoxins, especially with their chemical nature and quantity. Sirodesmins are phytotoxins from epipolythiodioxopiperazines group, produced by fungi Leptosphaeria maculans that is a cause of ...

Genetic Relationship of Brassicaceae Hybrids with Various Resistance to Blackleg Is Disclosed by the Use of Molecular Markers

Current Issues in Molecular Biology, 2022
Brassica napus is an important oil source. Its narrow gene pool can be widened by interspecific hybridization with the Brassicaceae species. One of the agronomically important traits, that can be transferred through the hybridization, is the resistance ...

Experimental dissection of phenotypic variation for quantitative disease resistance in canola (Brassica napus) – Leptosphaeria maculans interactions

Pest Management Science, EarlyView.
This graphical abstract illustrates how quantitative resistance to Leptosphaeria maculans in canola is experimentally estimated through multi‐environment replicated trials measuring crown canker severity. Genotype, environment and pathogen sources feed into phenotyping, followed by variance partitioning using mixed models and beta regression to ...

Sensitivity of winter rapeseed (Brassica napus L.) to isolates of the fungus Leptosphaeria maculans (Desm.) Ces. et de Not

Plant Protection Science, 2002
The pure cultures of the fungus Leptosphaeria maculans were isolated from the rapeseed leaves collected in Moravia. Two isolates were collected on the basis of their ability to produce yellow colour.

Effects of temperature and maturation of pseudothecia of Leptosphaeria maculans and L. biglobosa on oilseed rape stem debris

, 2003
Effects of temperature on maturation of pseudothecia of Leptosphaeria maculans and L. biglobosa, closely related species which coexist on UK oilseed rape, were investigated.

Discovery and characterisation of succinate dehydrogenase inhibitor resistance in Plenodomus biglobosus (phoma stem canker of oilseed rape)

Pest Management Science, EarlyView.
SDHI resistance is reported and characterised for the first time in the oilseed rape phoma stem canker pathogen Plenodomus biglobosus (Leptosphaeria biglobosa). We investigate cross‐resistance patterns, associated SDH target‐site mutations, possible fitness costs, and consider the implications for disease and resistance management.

Efficacy of Blackleg Major Resistance Genes in B. napus in Germany

Pathogens, 2022
Leptosphaeria maculans is one of the major pathogens of oilseed rape (B. napus). It causes blackleg disease, which accounts for significant yield losses worldwide.

Effects of fungicides on in vitro spore germination and mycelial growth of the phytopathogens Leptosphaeria maculans and L. biglobosa (phoma stem canker of oilseed rape)

, 2010
BACKGROUND: Phoma stem canker, caused by the coexisting related fungal pathogens Leptosphaeria maculans (Des.) Ces. & de Not and L. biglobosa Shoemaker & H Brun, is a major disease of winter oilseed rape in the UK.
