A rain tower and wind tunnel for studying the dispersal of plant pathogens by rain and wind
(1986-12)
The rain tower/wind tunnel complex at Rothamsted consists of a rain tower (height 11 m, cross-section 1 m2) linked to the upwind end of a wind tunnel (length 12 m, cross-section 1 m2), which may be operated in either an ...
Factors affecting the germination of Septoria nodorum pycnidiospores
(1986-09)
Most pycnidiospores of Septoria nodorum were released from pycnidia into water in 30 min, more than 50% being released in 10 min. The viability of pycnidiospores in aqueous suspension, assessed by germination on a selective ...
Effects of rainfall intensity and duration on dispersal of Rhynchosporium secalis conidia from infected barley leaves
(1986-06-30)
Simulated rain of two intensities was allowed to fall for 30 min on to barley leaves infected by Rhynchosporium secalis. The resulting splash droplets were collected on horizontal pieces of fixed photographic film. Most ...
Effects of irrigation and benomyl treatment on chocolate spot (Botrytis fabae) and yield of winter-sown field beans (Vicia faba)
(1986-03)
In 1976-7, 1977-8 and 1978-9 plots of winter-sown field beans, either irrigated in June and July or unirrigated, were treated with one or more sprays of benomyl or were untreated. The amounts of chocolate spot on field ...
Effects of leaf age, inoculum dose and freezing on development of chocolate spot (Botrytis fabae) lesions on field bean (Vicia faba) leaves
(1986-02)
Botrytis fabae spore suspensions containing c. 1, 10, 102, 103, 104, 105, or 106 spores/ml were used to inoculate 5, 17 or 30-day-old field bean leaves. The percentages of the leaf areas covered by, chocolate spot lesions ...
Spore dispersal in splash droplets
(Cambridge University Press, 1986)
Water is the solvent for metabolic processes, it participates directly in many biochemical reactions and has a vital skeletal function. It also plays a key role in the behaviour and spread of fungi. The chapters of this ...
The development of eyespot (Pseudocercosporella herpotrichoides) lesions in winter wheat crops
(1986)
The development of eyespot (Pseudocercosporella herpotrichoides) lesions on main shoots of plants in winter-sown wheat crops in 1981/82, 1982/83 and 1983/84 was studied by recording the incidence and penetration of leaf ...
Spore dispersal in relation to epidemic models
