A case study in measurement and analysis of disease gradients
(Association of Applied Biologists, 1995)
Effects of previous cropping and fungicide timing on the development of light leaf spot (Pyrenopeziza brassicae), seed yield and quality of winter oilseed rape (Brassica napus)
(1994-04)
Light leaf spot, caused by Pyrenopeziza brassicae, was assessed regularly on double-low cultivars of winter oilseed rape during field experiments at Rothamsted in 1990-91 and 1991-92. Previous cropping and fungicide ...
Dispersal of conidia of Ascochyta fabae f. sp. lentis from infected lentil plants by simulated wind and rain
(1994-02)
Splash was shown to be an effective mechanism for short-range dispersal of conidia of Ascochyta fabae f. sp. lentis, the cause of ascochyta blight of lentil. The dispersal gradients were well described by the power law ...
Spore dispersal and plant disease gradients : a comparison between two empirical models
(1987-03)
Power law and exponential models were fitted to 325 sets of observations which described decreases with distance in deposition of air-borne or splash-borne spores, or pollen, or in amounts of plant disease caused by fungi, ...
