2010年1月29日 · The occurrence of a blight disease caused by an Alternaria species on wheat [Triticum spp.] was first recorded by Kulkarni (1924) from Maharasthra and by McRae (1924) from Bihar, India. It was reported from Uttar Pradesh (India) by Mehta (1950) and from Andhra Pradesh (India) by Bener (1960) .

Alternaria triticina is a fungal plant pathogen that causes leaf blight on wheat. A. triticina is responsible for the largest leaf blight issue in wheat and also causes disease in other major cereal grain crops.

2006年4月25日 · Initial alternaria leaf blight symptoms consist of small (< 1 mm), oval, yellow lesions, irregularly scattered on the leaves. As the lesions enlarge, they appear irregular and dark brown to grey, surrounded by a bright yellow margin.

Leaf blight has caused serious damage on wheat [Triticum spp.] crops, particularly in eastern and central parts of India. It is now considered to be one of the most important foliar diseases of wheat grown in the major states of India (Nema, 1986).

•Leaf blight of wheat via Alternaria triticina is “one of the most important foliar diseases of wheat in India”. •Infection can lead to a 46-75% weight reduction of individual grains with yield losses reaching 60%. • In the 1960s, India saw widespread, heavy wheat yield losses due to …

Leaf blight (Alternaria triticina) is major disease in irrigated areas of MP. Given the significance of wheat leaf blight, a field investigation was done employing various fungicides and plant extracts to study their comparative efficacy in controlling foliar blight and yield of wheat in the field.

Management of leaf blight complex of wheat (Triticum aestivum) caused by Bipolaris sorokiniana and Alternaria triticina in different agroclimatic zones using an integrated approach. Indian Journal of Agricultural Sciences, 78(6):513-517.

2019年3月16日 · Alternaria alternata, ubiquitous pathogen on several foodstuffs, and A. triticina, known to be among the causal agents of wheat leaf blight in different geographic areas (Mercado Vergnes et al., 2006), both resulted the predominant species associated with grains, although other species of the Alternaria and Infectoriae sections have been ...

Alternaria spp., including Alternaria triticina and Alternaria alternata, cause black point disease in wheat, characterized by black discoloration on seeds and reduced seedling vigor. These pathogens thrive in high humidity and moderate temperatures, leading to significant reductions in

Leaf blight of wheat is caused by the fungus Alternaria triticina. This fungal disease infects wheat species and a small number of related cereals. Infection occurs through seed borne transmission, planting into infected soil, or from infested crop residues, where rain splash or leaves coming in direct contact with the soil leads to infection.
