Background: Downy mildew caused by Plasmopara halstedii is one of the most devastating diseases of sunflower worldwide. So far several dominant resistance genes designated as Pl have been identified and their molecular markers linked to these genes are available. However, no information on the resistance genes is available in Iranian lines. Objective: In this study, the presence of three map-b...

Susceptibility to diseases of economically important grapes is critical the evaluation germplasm recommended for commercial production and development sustainable systems. In 2018–2019, cold-hardy grape cultivars including ‘Brianna’, ‘Crimson Pearl’, ‘Itasca’, ‘Louise Swenson’, ‘Marechal Foch’, ‘Marquette’ ‘Petite ‘St. Pepin’, ‘Verona’ were evaluated on non-treated vines susceptibility downy mi...

Plant diseases and pests cause a large loss of world agricultural production. Downy mildew is major disease in grapevine. Conventional techniques for plant evaluations are time-consuming require expert personnel. This work investigates novel sensing technologies artificial intelligence applications assessing downy grapevine under laboratory conditions. In our methodology, machine vision applied...

In November 2018 severe downy mildew infection was observed on summer savory plants in Kermanshah Province, Iran. Leaves infected displayed chlorosis-browning the upper surfaces and abundant dark gray-brown sporulation of asexual morph lower surfaces. Based morphological characteristics molecular analyses using ITS-1 ITS-4, species identified as Peronospora saturejae-hortensis. The nucleotide s...
