Sphaerotheca fuliginea Causing Powdery Mildew of Cucumber—a New Record for Libyan Jamahiriya

Abstract

This paper presents, for the first time, the record of S. fuliginea in Libyan Jamahiriya as a causal organism of powdery mildew of cucumber in indoor and outdoor cultivations. Erysiphe cichoracearum DC., hitherto considered as the causal organism of cucumber powdery mildew, was not observed in included locations. This is also first report of occurrence of S. fuliginea on a cucurbit in the country. S. fuliginea is suggested to be recognised henceforth as causal organism of powdery mildew of cucumber in Libyan Jamahiriya.
