Download or read book Using Microbial Seed Treatment to Control Seed Rot and Damping Off in Chile Caused by Rhizoctonia Solani written by David Michael Hebert and published by . This book was released on 2017 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chile (capsicum annuum L.) is a major cash crop grown in New Mexico for its edible and ornamental pods. Its farm gate value in 2014 was approximately $38 million. Rhizoctonia solani (RS) is a soilborne fungal pathogen that causes seed rot and damping off in chile, leaving bare patches in affected fields. Under no management, plant infection in a field increases over time. Extreme cases necessitate replanting of fields, increasing production costs. This study characterized the virulence of RS isolates recovered from chile and rosemary and used the most virulent isolate to evaluate the efficacy of selected microbial seed treatments. RS-susceptible chile seeds (var. New Mexico 6-4) were surface-disinfested in 10% sodium hypochlorite solution for 15 min and either pre-germinated (PG) or not pre-germinated (NPG). Microbial experiments were two-way factorial treatment structures with complete randomized block design. Data were subjected to ANOVA. Microbial seed treatments consisted of combinations of 0.5% solutions of two species of Bacillus, 1% suspensions of four species of arbuscular mycorrhizal fungi in the genus Glomus, two species of Trichoderma and water only. After microbial treatment, PG and NPG seeds were placed into petri dishes or soil that was either infested with RS or not. Shoot length and fresh weight were collected 30 days after sowing treated NPG seeds and a disease rating scale was developed to quantify the level of infection in treated PG seeds every 4 days for a period of 12 days. In all tests, there was no seed rot or damping off in control treatment due to RS (non-treated and non-inoculated NPG or PG seeds). Conversely, all treated NPG and PG seeds in RS-infested soil and petri plates containing RS displayed severe symptoms of seed rot and damping off. None of the microbial treatments reduced seed rot or damping off caused by the extremely virulent isolate of RS used (RS AG-4, HGI). Lesions on seedlings grown in RS-infested soil were re-cultured and tested on fresh PG seeds, where symptoms and signs of seed rot and damping off reoccurred and pathogen was re-isolated.

Download or read book Diagnosing Hemp and Cannabis Crop Diseases written by Shouhua Wang and published by CABI. This book was released on 2021-08-18 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hemp and cannabis, both belonging to Cannabis sativa, have emerged as some of the most valuable crops because of their multiple functionalities - industrial, medicinal, and recreational uses. Like all other crops, they are at risk of diseases and pests. In certain cases, an entire hemp field can fail due to unexpected disease. As a new and highly regulated crop, research on Cannabis crop diseases is scarce, and the science of plant diagnostics is not well covered in the literature. Taking hemp/cannabis as a model crop, the book illustrates how to diagnose a disease problem and how to manage it effectively. It presents real disease cases encountered during crop production, and explains methods of diagnosis, both in the field and in the lab, in order to find out the cause(s).
Download or read book Diversity in Barley Hordeum vulgare written by R. von Bothmer and published by Elsevier. This book was released on 2003-07-03 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic diversity is one of the main resources sustaining human life. Food security largely depends on the availability and utilization of this diversity, which is of strategic importance for countries and companies. Conservation and utilization of biodiversity is thus currently an urgent area of global debate and concern. Barley is a major crop in the world used for food, feed and malt, and with a wide religious and ethnic importance. The crop was domesticated in Neolithic time in SW Asia and spread rapidly under cultivation to new areas. Nowadays it is one of the most widespread and widely adapted crops grown under contrasting edaphic conditions. Adaptations to new environments, different agricultural practices and selection for different uses have further added to the complex diversity pattern. Is it at all possible to give a complete picture of the diversity in a crop or wild species? Are we, by adding new technologies, only revealing parts of the diversity? Do different sets of data show similar or conflicting pictures of genetic diversity? Will the large genome size reduce the role of barley as a model organism in these current sequencing days? Or, are there still major reasons to continue to work with this beautiful crop? The aim of this book is to cover the complex issue of diversification in time and space in a single crop: barley. Leading scientists from various fields describe the entire variation pattern in different sets of characters and an attempt is made for a synthesis to a holistic picture. The book proposes ways to use the achievements of diversity studies in future research and breeding programmes.
Download or read book Pythium written by Mahendra Rai and published by CRC Press. This book was released on 2020-01-28 with total page 328 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pythium is one of the most important phytopathogens causing significant damage to agriculture, forest, and nurseries, etc. It is an unseen enemy of the root zone of various plants and hence considered as "hidden terror" for a number of plants. An accurate diagnosis and identification of Pythium causing various infections in plants is very important because it is often confused with several other fungi. Pythium infections are difficult to control once they have set in. Therefore, its effective and ecofriendly management is of paramount importance. In addition, there are many reports on Pythium causing infections in human beings and animals. The present book on Pythium focuses on various aspects which mainly include pathogenesis, technological developments in detection and diagnosis, and its management. Key Features Includes identification of Pythium spp. by traditional and molecular methods Deals with different diseases caused by Pythium spp Describes the role of Pythium in mammalian diseases Incorporates various management strategies Discusses emerging role of nanotechnological tools for the management of Pythium diseases
