We describe a novel method of fungal slide preparation named "agar block smear preparation." A total of 510 agar block smears of 25 fungal strains obtained from culture collections, 90 QC fungal strains, and 82 clinical fungal strains from our clinical microbiology laboratory, which included a total of 137 species of yeasts, molds, and thermal dimorphic fungi, were prepared and examined. In con...
Stenocarpella maydis is the most prevalent ear rot pathogen of maize (Zea mays) in South Africa, the United States, and other countries. Infection and ultrastructure of propagules of S. maydis in maize were observed by light, scanning, and transmission electron microscopy. Two-celled conidia of S. maydis were found in the tissues of husk and kernels. Mycelia colonized inter- and intracellularly...

Aim of study: Septoria tritici blotch (STB), caused by the fungus Zymoseptoria tritici, is one most important wheat diseases worldwide, affecting both bread and durum wheat. The lack knowledge about interaction with Z. together limited resources resistant material, have led to a rising threat for cultivation, particularly in Mediterranean Basin. In Spain, STB has increased its incidence last fe...
ABSTRACT The development of Didymella rabiei on debris of naturally infected chickpea was investigated in four chickpea-growing areas with different climatic conditions in Spain during 1987 to 1992. D. rabiei extensively colonized chickpea debris and formed pseudothecia and pycnidia. Differentiation of pseudothecial initials occurred regularly across experimental locations by November, 1 month ...
در این پژوهش واکنش 18 رقم گندم نان در برابر پنج جدایه از پنج استان کشور پس از تیمار بذری با سه سطح 0، 75/0 و 1 میلی مولار سالیسیلیک اسید در مقابله با قارچ Mycosphaerella graminicola در مرحله گیاهچه مورد بررسی قرار گرفت. نتایج حاصل از تجزیه واریانس داده ها نشان داد بین ارقام، جدایه ها، سطوح اسید سالیسیلیک و برهمکنش های رقم – جدیه و رقم- غلظت اختلاف معنی دار وجود دارد. هفتادوهشت درصد ارقام مورد ب...
