Improving strategies to control stem canker in the UK
(1999)
The fungicides difenoconazole, flusilazole + carbendazim, prochloraz + carbendazim and tebuconazole applied as two or four spray treatments at full or half dose gave good control of phoma leaf spot on canker-susceptible ...
Optimising fungicide timing for controlling light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in the UK
(Association of Applied Biologists, 1999)
Investigating the horizontal spatial spread of light leaf spot (Pyrenopeziza brassicae) of winter oilseed rape in the UK
(Association of Applied Biologists, 1999)
Relationships between regional weather and incidence of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape in England and Wales
(Association of Applied Biologists, 1999)
Effects of diseases on the growth and yield of winter linseed
(Association of Applied Biologists, 1999)
Optimising the use of fungicides to control stem canker of oilseed rape
(1999)
Ascospores of Leptosphaeria maculans infect leaves of oilseed rape to cause leaf spots, from which the fungus can grow to infect the stem. Yield losses due to early senescence and lodging result if the stem infections reach ...
Sampling winter oilseed rape crops to assess incidence of light leaf spot (Pyrenopeziza brassicae)
(Association of Applied Biologists, 1999)
Modelling the progress of light leaf spot (Pyrenopeziza brassicae) on winter oilseed rape (Brassica napus) in relation to weather criteria
(Association of Applied Biologists, 1999)
Conditions for infection of winter oilseed rape leaves by conidia and ascospores of Pyrenopeziza brassicae, causing light leaf spot
(1999)
The optimum temperature for infection of oilseed rape leaves by P. brassicae conidia was c.16°C; an increase of temperature above the optimum and a decrease of temperature below the optimum decreased infection by conidia. ...
Yield loss of winter oilseed rape in relation to severity of stem canker (Leptosphaeria maculans ) in the UK
(1999)
The relationships between yield loss and incidence or severity of stem canker in winter oilseed rape were analysed using data from experiments at Rothamsted in 1991/92, Withington in 1992/93, Boxworth in 1993/94 and ...
