Diseases survey has been conducted by the end of April, period during which growth stages of wheat ranged from anthesis to physiological maturity. Prospected regions are Saïs, Gharb, Loukkos, and Zaïr plains, and also Rif and middle Atlas mountains. All along roads, we stopped every 15 to 20 kilometers to inspect bread and durum wheat fields. The data collected were host species and its growth stage, and incidence and severity of fungal diseases identified on the basis of symptoms. The results of this survey showed that the complex Septoria-Tan spot and Leaf rust were the most prevalent diseases in prospected areas. However, Stripe (Yellow) rust, Powdery mildew, Stem rust, Loose smut, and Root rot have been identified on some fields of both durum and bread wheat but with a prevalence (percentage of contaminated fields) and severity that varied from year to year.
