Relating plant and pathogen development to optimise fungicide control of phoma stem canker (Leptosphaeria maculans) on winter oilseed rape (Brassica napus)
(2007-08)
In winter oilseed rape experiments at Rothamsted in 2000/01 to 2002/03 growing seasons, the severity of phoma stem canker epidemics in summer depended on the timing of phoma leaf spot epidemics in the previous autumn, and ...
Resistance to infection by stealth : Brassica napus (winter oilseed rape) and Pyrenopeziza brassicae (light leaf spot)
(2007-08)
Light leaf spot (Pyrenopeziza brassicae) is an important disease on winter oilseed rape crops (Brassica napus) in northern Europe. In regions where economically damaging epidemics occur, resistance to P. brassicae in ...
White leaf spot
(American Phytopathological Society (APS) Press, 2007-07-15)
Two weather-based models for predicting the onset of seasonal release of ascospores of Leptosphaeria maculans or L-biglobosa
(2007-06)
Weather-based models (Improved Blackleg Sporacle and SporacleEzy) to predict the date of onset of seasonal release from oilseed rape debris of ascospores of Leptosphaeria maculans or L. biglobosa, causes of phoma stem ...
Use of fungicides to control chocolate spot (Botrytis fabae) on winter field beans (Vicia faba)
(2007-04-05)
Less chocolate spot (% leaf area affected) developed on winter–sown field beans sprayed with benomyl than on untreated beans or beans sprayed with iprodione, prochloraz or thiabendazole. A single benomyl spray during ...
Comparison of Leptosphaeria biglobosa-induced and chemically induced systemic resistance to L-maculans in Brassica napus
(2007-04)
Brassica napus (cv. Madrigal) seedlings pre-treated with ascospores of Leptosphaeria biglobosa or foliar sprays of either acibenzolar-S-methyl (ASM) or menadione sodium bisulphite (MSB) were challenge inoculated with L. ...
The SECURE project – Stem canker of oilseed rape: : molecular methods and mathematical modelling to deploy durable resistance
(2007-03-26)
Modelling done during the SECURE project has demonstrated the dynamic nature of the interaction between phoma stem canker (Leptosphaeria maculans), the oilseed rape host (Brassica napus) and the environment. Experiments ...
Effect of spray timing of flusilazole on the incidence and severity of phoma leaf spot (Leptosphaeria maculans and L. biglobosa) on winter oilseed rape
(Association of Applied Biologists, 2007)
