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 ...
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 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 ...
Spore dispersal in relation to epidemic models
(Macmillan, 1986)
Effects of water potential and temperature on the development of eyespot lesions in wheat
(1985-08)
Growth of Pseudocercosporella herpotrichoides on potato dextrose agar at water potentials from -0.5 to -6.9 MPa was optimal at 20°C. At 12 and 20°C, six isolates of P. herpotrichoides grew more rapidly at -0.5 to -2 MPa ...
Epidemiology and control of chocolate spot (Botrytis fabae) on winter field beans (Vicia faba)
(1985-06)
Dispersal of Botrytis fabae spores and the development of chocolate spot lesions were monitored in crops of winter-sown field beans during the 1980/81, 1981/82 and 1982/83 seasons. The greatest numbers of B. fabae spores ...
Dispersal of Septoria nodorum pycnidiospores by simulated raindrops in still air
(1985-04)
Simulated raindrops, diameter c. 3 or 4 mm, fell 13 m down a raintower onto suspensions of Septoria nodorum pycnidiospores, depth 0.5 mm, or infected straw pieces. Splash droplets were collected on pieces of fixed photographic ...
