Abstract:
Ascochyta fabae is a major parasite of faba bean causes ascochyta blight disease. Two controlled
condition experiments were conducted to study the temperature effect on mycelial growth and sporulation of
A. fabae, 5 days after incubation. The maximum average of mycelial growth was 75 mm on 5 days and
sporulation was 24 × 103 conidia ml 1 and mycelial growth was increasing by 15 mm day 1, were recorded at
22°C. The least values of these parameters were obtained in 26 and 30°C. Such parameters were linearly
increased with temperature to maximum and declined progressively in both reaction evaluation tests. The two
evaluation tests indicated
