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 ...
Gibellina cerealis, an unusual pathogen of wheat
(1985)
The numbers of wheat plants infected by Gibellina cerealis in a long-term wheat and fallow experiment were recorded annually from 1935 to 1978. Infected plants were few in number and generally widely separated. Overall, ...
Construction of dispersal models
(Academic Press, 1985)
Role of wind and rain in dispersal of Botrytis fabae conidia
(1985)
Numbers of Botrytis fabae conidia dispersed in plots of winter-sown field beans in which chocolate spot developed were monitored with vertical cylinder and horizontal slide samplers exposed within crops for 3- or 4-day ...
Dispersal of Septoria nodorum pycnidiospores by simulated rain and wind
(1985)
The influence of wind on the splash dispersal of Septoria nodorum pycnidiospores was studied in a raintower/wind tunnel complex with single drops or simulated rain falling on spore suspensions or infected stubble with ...
