Pests were monitored on linseed crops in Hertfordshire, Cambridgeshire and Bedfordshire from 1987 to 1990. Adult flea beetles (Aphthona euphorbiae and Longitarsus parvulus) caused severe injury to seedlings; their numbers ...
Philip Herries Gregory 1907-1986 : pioneer aerobiologist, versatile mycologist
(1997-09)
Philip Gregory pioneered aerobiology as a topic for research, drawing together inputs from many disciplines to contribute to better understanding of fungal spore dispersal, plant disease epidemiology, and allergy. In ...
Effect of wind on the dispersal of oospores of Peronosclerospora sorghi from sorghum
(1997-06)
The effect of wind on the dispersal of oospores of Peronosclerospora sorghi, cause of sorghum downy mildew (SDM) is described. The oospores are produced within the leaves of aging, systemically infected sorghum plants. ...
Sampling bioaerosols in plant pathology
(1997-04)
Bioaerosols of interest in plant pathology are comprised principally of the air-borne or splash-borne fungal spores or bacterial cells which disperse many plant diseases. Plant pathogen inoculum is mostly sampled out of ...
Temperature and Effects of Seed-borne Botrytis cinerea or Alternaria linicola on Emergence of Linseed (Linum usitatissimum) Seedlings
(1997-04)
Experiments were done at temperatures from 5 to 20 degrees C to investigate the effects of infection of linseed seed (cv. Antares) by Botrytis cinerea or Alternaria linicola on seedling emergence and to study transmission ...
Effects of temperature, cultivar and isolate on the incubation period of white leaf spot (Mycosphaerella capsellae) on oilseed rape (Brassica napus)
(1997-04)
When leaves of oilseed rape (cv. Cobra) were inoculated with conidial suspensions of Mycosphaerella capsellae (white leaf spot) and incubated in controlled environments, the lag period from inoculation to the appearance ...
