(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 ...
Effects of rainfall intensity and duration on dispersal of Rhynchosporium secalis conidia from infected barley leaves

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 ...
