Bipolaris sorokiniana is a phytopathogenic fungus causing diseases of cereal crops such as common root rot, the leaf spot disease, seedling blight, and black point of the grain. Random-amplified polymorphic DNA (RAPD) assay was used to investigate the genetic diversity of 20 isolates collected from different cultivars in wheat-producing regions in Brazil. Seventy primers, with random nucleotide...

Pennyroyal (Mentha pulegium) leaves with small irregular or ellipsoidal necrotic spots were collected in a suburb area of Ardal city, Chaharmahal and Bakhtiari province Iran summer 2018. A fungal isolate was recovered from diseased tissue identified as Bipolaris sorokiniana based on morphological characteristics partial sequence the gpdh gene. In pathogenicity study, disease symptoms observed i...

The objects of research were the first leaves green seedlings spring barley (Hordeum vulgare L.) varieties Belarusian breeding − filmy (Magutny, Raider) and naked (Adamant). Seedlings different age (3, 5, 10 days old) infected with spores fungus Bipolaris sorokiniana (Sacc.) Shoem. a causative agent helminthosporiasis, analyzed 2 after infection. Varietal ontogenetic differences between cultiva...

In Australia, crown rot of cereals is predominantly caused by Fusarium pseudograminearum and culmorum, common root Bipolaris sorokiniana. graminearum an important pathogen causing head blight worldwide has also been reported to cause wheat. The comparative ability F. pseudograminearum, B. sorokiniana across a range winter cereal species requires investigation. glasshouse trials, we inoculated o...

abstract the root and foot rot of wheat is one of the important disease of wheat over the world. the root and foot rot of wheat observed more frequently in the resent years at khorasan province (northeast of iran). for investigation the causal agents, several samples were collected from wheat fields of north khorasan in 2007 and 2008. culture of diseased parts of plants on pda resulted. fusariu...

ABSTRACT Stenotrophomonas maltophilia strain C3 was evaluated for control of leaf spot on tall fescue (Festuca arundinacea) caused by Bipolaris sorokiniana. In growth chamber experiments, C3 inhibited conidial germination on leaf surfaces and reduced lesion frequency and percent diseased leaf area compared with nontreated controls. The amount of leaf spot suppression was related to the C3 dose ...
