Quantitative Models for Germination and Infection of Pseudoperonospora cubensis in Response to Temperature and Duration of Leaf Wetness

PHYTOPATHOLOGY, 100(9), 959–967.

By: L. Arauz*, K. Neufeld*, A. Lloyd* & P. Ojiambo*

author keywords: cucurbit downy mildew; disease forecasting
MeSH headings : Cucumis melo / microbiology; Oomycetes / physiology; Plant Diseases / microbiology; Spores / physiology; Temperature; Time Factors; Water
TL;DR: Three response surface models based on modified forms of the Weibull function were evaluated for their ability to describe germination of sporangia and infection in response to temperature and leaf wetness duration and were used to construct risk threshold charts that can be used to estimate the potential risk for infection based on observed or forecasted temperature and Leaf Wetness duration.

EFFECT OF INTERRUPTED WETNESS PERIODS ON SPORE GERMINATION AND APPLE INFECTION BY BOTRYOSPHAERIA-OBTUSA

PHYTOPATHOLOGY, 80(11), 1218–1220.

By: L. Arauz* & T. Sutton

TL;DR: Conidia of Botryosphaeria obtusa were allowed to germinate in water for 4 hr at 24 C, were air-dried, and were rewetted following dry periods ranging from 0 to 8 hr and no increase in germ tube length was observed 4 hr after rewetting in any treatment. (via Semantic Scholar)

PROTECTANT AND AFTER-INFECTION ACTIVITY OF FUNGICIDES AGAINST BOTRYOSPHAERIA-OBTUSA ON APPLE

PLANT DISEASE, 74(12), 1029–1034.

By: L. Arauz* & T. Sutton

TL;DR: Reduction of radial growth of Botryosphaeria obtusa on fungicide-amended potato-dextrose agar medium was determined and six of the fungicides were tested for their protectant and eradicant activity against B. Obtusa. (via Semantic Scholar)

SIMULTANEOUS USE OF INFECTION CRITERIA FOR 3 APPLE DISEASES FOR TIMING OF FUNGICIDE SPRAYS

PHYTOPATHOLOGY, 80(11), 1212–1218.

By: L. Arauz*, T. Sutton & L. Pope

TL;DR: The feasibility of using criteria for infection by Botryosphaeria obtusa, Venturia inaequalis, and Gymnosporangium juniperi-virginianae on foliage of apple in a combined weather-based forecasting system for frogeye leafspot, apple scab, and cedar-apple rust was evaluated through computer simulation and in a field study.
