Colletotrichum gloeosporioides sensu stricto, the causal agent of a leaf spot disease of Schefflera arboricola in Iran
Schefflera arboricola is a flowering plant in the family Araliaceae; its common name is dwarf umbrella tree. It is an evergreen shrub and a popular ornamental plant, commonly grown as an indoor plant. During a sampling in 2015, a new leaf spot symptoms was observed on S. arboricola plants in several greenhouses in the Hamadan province, Iran. Most of the plants were se...
متن کاملMolecular Phylogeny and Morphology of Mycosphaerella nawae, the Causal Agent of Circular Leaf Spot on Persimmon
In this study, the phylogeny and morphology of Mycosphaerella nawae (Dothideomycetes, Ascomycota) were examined using Korean and Japanese isolates, to establish the phylogenetic relationship between M. nawae and its allied species. Korean and Japanese isolates of M. nawae were collected from circular leaf spot-diseased leaves and were confirmed based on internal transcribed spacer (ITS) sequenc...

متن کاملGenetic variability of Paecilomyces variotii isolates causal agent of Die-back disease using rDNA-ITS and RFLP markers
Paecilomyces variotii is one of the most important causal agents of dieback disease in pistachio (Pistacia vera) gardens. The disease affects different parts of the tree, such as branch and trunk. Assessment of genetic structure in different populations of this species will lead to more useful management of pistachio dieback disease. In this study, genetic variation within samples of P. varioti...
متن کاملIn vitro Evaluation of Some Fungicides and Tea Extract Against Pestalotia sp. and Colletotrichum sp., The Causal Agents of Leaf Spot and Anthracnose of Azalea
The effect of five fungicides and tea extracts was tested against anthracnose disease and leaf spot of Azalea during summer (2015) at the laboratory in Rasht Branch, Islamic Azad University. Commercially formulated fungicides at 1000, 2000 and 3000 ppm concentrations and the regression of normalized growth rate were used to determine the EC50. The application of different fungicides on Pestalot...
