Status of False Smut of Rice in Gujarat

Biological Forum
False smut caused by Ustilaginoidea virens (Cooke) Takahashi is known to cause significant quantitative and qualitative losses in grain yield. In response to the destructive nature of the pathogen, a survey was conducted during the Kharif 2024 in Anand, Kheda and Ahmedabad districts of Gujarat.

Status of false smut of rice in different districts of West Bengal

Oryza-An International Journal on Rice, 2022
False smut of rice which was considered a minor disease of rice is presently spreading in most of the rice growing areas of the world causing reduction in yield and quality of the produce. West Bengal is the largest producer with largest area under rice in India.

INHERITANCE OF RESISTANCE TO LOOSE SMUT, COVERED SMUT AND FALSE LOOSE SMUT IN THE BARLEY VARIETY JET

Canadian Journal of Plant Science, 1962
The inheritance of reaction to single cultures of Ustilago nuda (Jens.) Rostr., Ustilago nigra Tapke, and Ustilago hordei (Pers.) Lagerh. was studied in the F1, F2 and F3 generations of crosses between the resistant barley variety Jet and the susceptible varieties Vantage and Plush.

Understanding and enhancing rice resistance to false smut disease

Journal of Genetics and Genomics
Flower-infecting fungi have caused many economically important diseases in crop production. The fungal pathogen Ustilaginoidea virens infects developing rice florets, causing false smut disease, which leads to reduced grain yield and quality, as well as contamination with mycotoxins that pose hazards to human health and food security.

Management of false smut of rice with new fungicidal molecules

Advances in Applied Research, 2016
Field experiments were carried out during thaladi season of 2012 - 2013 and 2013 - 2014 at Tamil Nadu Rice Research Institute, Aduthurai, Thanjavur, to study the effect of new fungicidal molecules on the false smut disease (Ustilaginoidea virens), incidence of rice. Foliar spray of Trifloxystrobin 25% + Tebuconazole 50% (0.4 g L"1) and Propiconazole 25

Rice false smut (Ustilaginoidea virens) in Egypt

Journal of Plant Diseases and Protection, 2004
Rice false smut (RFS) caused by Ustilaginoidea virens (Cke.) Tak. (Teleomorph: Claviceps oryzae sativae Hashioka) is a sporadic disease where rice (Oryza sativa L.) is cultivated. Rfs is a new disease in Egypt and appeared for the first time in the Nile Delta in 1997. This paper is the first record of Rfs in Egypt.

Study on identification of Rice False Smut based on CNN in natural environment

2017 10th International Congress on Image and Signal Processing, BioMedical Engineering and Informatics (CISP-BMEI), 2017
The widely distributed Rice False Smut(RFS) is one of the most harmful viruses for rice. However, it's identification methods are based on subjective judgment. In this paper, two methods are put forward to identify the RSF under natural conditions. One is the traditional ML(machine learning) classification method SVM (Support Vector Machine) combined ...

A candidate gene for the determination of rice resistant to rice false smut

Molecular Breeding, 2020
In recent years, rice false smut (RFS) has grown from being a minor to a major disease affecting rice productivity. The genetic basis of the host’s defense against RFS is currently under-researched. In this study, a rice variety Nanjing11 with stable resistance to RFS from years under naturally infected field condition was identified.

Plant pathology: The infection source of rice false smut fungi

Current Biology
Rice false smut, caused by the fungal pathogen Ustilaginoidea virens, is a devastating disease affecting major rice-growing regions. A new study reveals that exopolysaccharides secreted by rhizosphere Sphingomonadaceae bacteria break the dormancy of U. virens chlamydospores and facilitate root colonization.

False smut of rice: Epidemiology, impact, and management strategies

Agrica
AbstractRice is a global staple food for more than half of the world's population. It is the third most important crop grown after Wheat and Maize in the world. It is cultivated in more than 100 countries and is a significant component of the daily diet in many Asian countries. China, India, Bangladesh, Vietnam, Indonesia, Thailand, Philippines, Brazil,
