Leaf blight caused by Alternaria sp. is one of the most important and destructive disease of marigold causing severe yield loss in all marigold growing areas of Southern Tamil Nadu. The pathogen Alternaria sp. causing leaf blight disease was isolated from disease infected leaves by tissue segment method and the pure culture was obtained through single hyphal tip method. The isolates proved its pathogenicity on the marigold hybrid tall yellow. Molecular characterization of the isolate at genus…

Strategies for the Management of Leaf Blight Disease Caused by Alternaria alternata in Gloriosa superba (L.)

Leaf blight caused by Alternaria alternata (Fr.) Keissler is a severe disease of Gloriosa, causing severe yield loss in every part of Gloriosa growing areas of Tamil Nadu. The foliar pathogen was

In vitro antifungal evaluation of various plant extracts against leaf blight disease of Jasminum grandiflorum caused by Alternaria alternata (Fr.) Keissler

The effective plant extracts and oils screened for antifungal activity have potential to be developed as potent fungicides in organic farming.

Evaluation of Essential Oils against Early Blight (Alternaria solani) of Tomato

The fungicidal effect of some essential oils viz., Neem, Eucalyptus, Pongamia, Lemongrass, Thyme and Clove were evaluated against Alternaria solani causing early blight of tomato resulting in severe

Effect of pulsed magnetic field on seed borne pathogen and germination of tomato

Experimental results indicated that all the treatments were significantly different and the seeds treated for 20 and 25 days showed the minimum percent disease incidence with highest percent disease inhibition over control, and control recorded the minimum plant biometrics.

Cold Plasma Treatment for the Control of Alternaria solani causing Early Blight of Tomato

Nonthermal plasma is characterized by low energy of its heavy particles (ions, molecules), which means it does not damage thermally sensitive material, but its electrons reach sufficient energy to participate in plasma-chemical reactions.



Identification and characterization of Alternaria alternata (Fr.) Keissler causing Ceratonia Blight disease of carob (Ceratonia siliqua L.) in Turkey

The putative pathogen was pathogenic on the inoculated carob plants and was consistently re-isolated from the symptomatic plant leaves and thereby satisfying the Koch’s postulates.

Occurrence of Alternaria alternata causing Alternaria blight in pigeonpea in India

The phylogenetic tree based on rDNA-ITS analysis showed that the Alternaria alternata causing Alternaria blight in pigeonpea is very distinct from the other Alternaria isolate reported from different host.

Cultural, morphological, pathogenic and molecular variability amongst tomato isolates of Alternaria solani in India

Based on the pathogenicity, isolates of A. solani were rated as virulent or less virulent based on percentage disease incidence data, and most efficient amplification and polymorphism of DNA was found with random primer 5′-CGCGTTCCTG-3′.

Development of specific primers for detection and identification of Alternaria spp. in carrot material by PCR and comparison with blotter and plating assays

A PCR-assay based on the specific primers developed seems to be a good alternative for the deep-freeze-blotter method and plating on ARSA, especially when time is an important issue.

Status and symptomatology of Alternaria leaf blight (Alternaria alternata) of Gerbera (Gerbera jamisonii) in Kashmir valley

The pathogen associated with the disease was identified as Alternaria alternata (Fr. Keissler).

Marigold Leaf Spot Caused by Alternaria tagetica New to Japan

A mitosporic fungus isolated repeatedly from the diseased plants was identified as Alternaria tagetica and demonstrated to cause the disease, and the name “hanten-byô”, which means leaf spot in Japanese, is proposed for this disease.

Phologeny of Alternaria fungi known to produce host-specific toxins on the basis of variation in internal transcribed spacers of ribosomal DNA

It is suggested that Alternaria pathogens which produce host-specific toxins are pathogenic variants within a single variable species, A. alternata, which belongs to a monophyletic group together with A. alternateata.

Morphological and molecular identification of pathogenic fungal of post-harvest tomato fruit during storage

Three pathogenic fungi of tomato were separated by using transconjugate method and identified by morphological characteristics and internal transcribed spacers ribosomal DNA (ITS rDNA) sequence analysis and showed that FQ1 belong to Alternaria alternate, FQ2 belong toCladosporium and FQ3 belongs to Fusarium sp.

PCR and real-time PCR assays to detect fungi of Alternaria alternata species.

Easy to perform and interpret PCR and real-time PCR assays enabling fast and unambiguous identification of A. alternata pathogens are presented.

Introduction to Fungi

A fungus is a eukaryote that digests food externally and absorbs nutrients directly through its cell walls and is called saprotrophs (saprophytes, saprobes).
