Abstract

Aim: The study was aimed to identify the economically important and to indicate the distribution of faba bean and field pea diseases in four selected highland districts namely: Bore, Anna Sorra, Dama and Uraga of Guji zone.

Materials and Methods: The survey was made along the main roads and accessible routes in each surveyed districts at every 5-10 km intervals as per faba bean and field pea fields available. Five samples were taken in each faba bean and field pea fields by moving “W” fashion.

Results: The observed diseases were chocolate spot, ascochyta blight and faba bean rust for faba bean in order of their prevalence. The overall mean incidences of faba bean diseases were 99%, 98% and 21%, respectively. Mean severity scale of chocolate spot and ascochyta blight were 3.3 and 2.7 in their previous order. Those diseases were more sever in Anna Sorra followed by Bore and Dama districts. Based on mean severity faba bean rust was recorded 11.5%. Ascochyta blight and powdery mildew were the two identified diseases of field pea during survey. The mean prevalence and incidence value of ascochyta blight of field pea was 62.4% and 64.6% respectively. The severity of ascochyta blight was low with the mean value of 1.8.The occurrence and distribution of powdery mildew was very low with the mean incidence of 5.8%. Chocolate spot and ascochyta blight were the two most devastating and widely disseminated in the surveyed areas.

Conclusion: It was concluded that diseases are the most devastating agents from an economic standpoint and the most difficult to protection efforts. It is mainly associated with lack of detailed information of economically important faba bean and field pea disease that cause yield loss of the areas.
