Abstract
A study was initiated to investigate powdery mildew disease on pepper during the growing season 2019/2020. Disease incidence scored 73, 85, 80 and 56% in Al-Mahmudiyah, Al-Yusufiyah and Al-Jadriya/Baghdad and Suwaira/Wasit, respectively. Morphological identification revealed L. taurica formed dimorphic conidia, lanceolate primary conidia and cylindrical to clavate secondary conidia. Conidiophores were straight, having short hyaline and unbranched baring single conidiospores. Sequence comparison of ITS region confirmed L. taurica shared 99% maximum nucleotide identity with sequences from South Korea (MH698492.1), Mexico (MG571545.1) and Australia (MT125857.1). To the best of our knowledge, this is the first molecular confirmation of L. taurica infecting pepper in Iraq.
