abstract = {Predicting infections by Puccinia striiformis f. sp.
tritici, with sufficient lead times, helps determine whether
fungicide sprays should be applied in order to prevent the
risk of wheat stripe rust (WSR) epidemics that might
otherwise lead to yield loss. Despite the increasing threat
of WSR to wheat production in Morocco, a model for
predicting WSR infection events has yet to be developed. In
this study, data collected during two consecutive cropping
seasons in 2018–2019 in bread and durum wheat fields at
nine representative sites (98 and 99 fields in 2018 and
2019, respectively) were used to develop a weather-based
model for predicting infections by P. striiformis. Varying
levels of WSR incidence and severity were observed according
to the site, year, and wheat species. A combined effect of
relative humidity > $90\%,$ rainfall ≤ 0.1 mm, and
temperature ranging from 8 to 16 °C for a minimum of 4
continuous hours (with the week having these conditions for
$5\%$ to $10\%$ of the time) during March–May were optimum
to the development of WSR epidemics. Using the weather-based
model, WSR infections were satisfactorily predicted, with
probabilities of detection ≥ 0.92, critical success index
ranging from 0.68 to 0.87, and false alarm ratio ranging
from 0.10 to 0.32. Our findings could serve as a basis for
developing a decision support tool for guiding on-farm WSR
disease management, which could help ensure a sustainable
and environmentally friendly wheat production in Morocco},
