tailieunhanh - Identification of Alternaria alternata

The present study was on identification of Alternaria alternata which responable for Alternaria leaf spot in Asalio. The disease was found to be very severe in all Asalio growing areas causing heavy destruction. The main aim of this study clearly demonstrated that A. alternata is a primary pathogen in Asalio, causing a leaf-spot disease. Isolates of Alternaria sp. were collected from leaf spot disease infected samples of Asalio in the fields around Udaipur. | 2020 9 2 1011-1015 International Journal of Current Microbiology andAppliedSciences ISSN 2319-7706 Volume 9 Number 2 2020 Journal homepage http Original Research Article https Identification of Alternaria alternata 1 1 1 1 2 Poonam Kumari1 Amit Trivedi1 Sakshi Meena1 Akansha Deora1 Shivam Maurya2 department of Plant Pathology Maharana Pratap University of Agriculture and Technology Udaipur Rajasthan India department of Plant Pathology Sri Karan Narendra Agriculture University Jobner Jaipur Rajasthan India Corresponding author ABSTRACT Keywords Alternaria alternata identification ITCC_________ Article Info Accepted 08 January 2020 Available Online 10 February 2020 The present study was on identification of Alternaria alternata which responable for Alternaria leaf spot in Asalio. The disease was found to be very severe in all Asalio growing areas causing heavy destruction. The main aim of this study clearly demonstrated that A. alternata is a primary pathogen in Asalio causing a leaf-spot disease. Isolates of Alternaria sp. were collected from leaf spot disease infected samples of Asalio in the fields around Udaipur. The pathogen was isolated from sample on PDA media in slants. These cultures were sent for final identification to Indian Type Culture Collection Identification Culture supply Services Division Of Plant Pathology Indian Agricultural Research Institute New Delhi-110012 . These ciltures were identified as Alternaria alternata. Introduction Asalio is mainly affected by diseases like Alternaria leaf spot white rust. The Rabi season Asalio crop in India is commonly affected by Alternaria leaf spot. The disease causes extensive damage to the quality and quantity of the foliage and grains. If persistent cloudy and cool weather prevails the blight appears after flowering stage of the crop. Alternaria genus is the largest genus. It is distributed worldwide and has been reported on .
