Available in PDF, EPUB and Kindle. Book excerpt: "Early-warning systems for plant diseases are valuable when the systems provide timely forecasts that farmers can use to inform their pest management decisions. To evaluate the value of the systems, this study examines, as a case study, USDA's coordinated framework for soybean rust surveillance, reporting, prediction, and management, which was developed before the 2005 growing season. The framework's linchpin is a website that provides real-time, county-level information on the spread of the disease. The study assesses the value of the information tool to farmers and factors that influence that value. The information's value depends most heavily on farmers' perceptions of the forecast's accuracy. The study finds that the framework's information is valuable to farmers even in a year with a low rust infection like that of 2005. We estimate that the information provided by the framework increased U.S. soybean producers' profits by a total of $11-$299 million in 2005, or between 16 cents and $4.12 per acre, depending on the quality of information and other factors. The reported cost of the framework was between $2.6 million and almost $5 million in 2005." [p.i].

Book excerpt: Plants are important for a permanent ecosystem, because in the ecological pyramid plants support all the other living organisms at the base. Very important organization is thought to be the integral process of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants. Accordingly, it is important to obtain more information about the knowledge concerning yield, biomass, and productivity in plants. Soybean is one of the main crops largely contributing to our life, which is thought to be connected to our ecosystem through the above-mentioned integral process. This book focuses on the soybean, and reviews and research concerning the yield, biomass, and productivity of soybean are presented herein. This text updates the book published in 2017. Although there are many difficulties, the main aim of this book is to present a basis for the above-mentioned integral processes of resource, transport, partitioning, metabolism, and production, which involves yield, biomass, and productivity in plants (soybean), and to understand what supports this basis and the integral process. It is hoped that this and the preceding book will be essential reads.
Download or read book Soybean Rust written by Laura Sweets and published by . This book was released on 2004 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: Asian soybean rust is a serious foliage disease that has the potential to cause significant soybean yield losses. Although Asian soybean rust was identified on soybean plants in Hawaii in 1994, the disease was not reported in the continental United States until the fall of 2004. The U.S. Department of Agriculture (USDA) released an official notice of the confirmation of soybean rust on soybean leaf samples collected in Louisiana on Nov. 10, 2004. Over the next few weeks the fungus was detected on plants from a number of additional states, including Missouri. Now that Asian soybean rust has been found in the continental United States, it is critical that anyone involved in soybean production be familiar with the disease and its identification and management. This publication will describe the history, symptoms, development and management of soybean rust.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Brazil is the first soybean producer in the world, and the largest exporter. In the 2019/20 harvest, the country produced about 124.85 million tons, representing 30% of world production. Global soy production for 2019/20 reached 337.9 million tons. Asian soybean rust (ASR) is the most pathogen on soybean in Brazil in nowadays. Target spot and Septoria leaf spot plus white mold complete these scenarios. ASR emerged in Brazil in 1979. The use of fungicides in the soybean crop in Brazil intensified after the master of 2002 with the resurgence of soybean rust, where the use of triazoles intensified. The massive sprays to pathogen control reached 3.5 sprays per season. In 2006, the first reports of loss of sensitivity of the fungus to the group appeared, notably for the fungicide flutriafol and tebuconazole used in many situations in a curative way or to eradicate the fungus. From that moment on, the productive system sought to use triazoles and strobilurins. In 2011 came the first reports of loss of sensitivity of the fungus in the group of strobilurins. This fact was due to the use of pyraclostrobin in the vegetative phase of soybeans without protection by multisite. That same year, the introduction of the active ingredients in copper oxychloride, mancozeb and chlorothalonil took place in Brazil. In 2015, the first carboxamides ((benzovindiflupyr) (solatenol and fluxpyroxade) associated in triple mode with triazoles and strobilurins were launched on the Brazilian market. Due to the specific mode of action in the metabolism of the fungus (biosynthesis of ergosterol (triazoles), mitochondrial respiration in the cytochrome oxidase enzyme complex - QOIs (strobilurins) and succin dehydrogenase - SDHIs (carboxamides), the need for their association in the sprayings was seen. To multisite (cuprics, dithiocarbamates and nitriles). For the sustainable management of the disease in Brazil, control strategies are recommended, such as the use of systemic fungicides, with a specific biochemical mechanism of action with the adoption of tank mix with multisite, adoption of cultural practices (sanitary emptiness) and sowing schedule and the use of varieties with quantitative resistance (partial or horizontal resistance). These measures will guarantee the sustainability of the culture and the useful life of systemic fungicides or specific sites.

Book excerpt: The potential outbreak of Asian soybean rust or ther devastating crop pathogens, either as an act of biowarfare or natural outbreaks is threat to food production and security in the U.S. and around the world. Asian soybean rust is a fungal pathogen that can cause significant yield loss in soybean. In areas where the pathogen is common, yield losses of up to 80% have been reported. This report summarizes the activities and results of a project initiated to evaluate the use NASA Earth science data for surveillance of soybean rust. Although soybean rust has since been found in the continental U.S., at the time of project initiation, rust was not an immediate threat to American agriculture. Thus, ground data were collected in Brazilian state of Mato Grosso near the city of Campo Novo do Parecis. Ground data was then used in conjunction with NASA Earth science data (specifically MODIS) in an attempt develop 1) a soybean crop-type classification; and 2) identify soybean rust.Temporal vegetation index products derived from MODIS were successfully used to develop a soybean crop-type classification for the study area. However, detection of the rust pathogen was difficult using available Earth science data, and suitable results were not obtained. Nonethe-lee, the results of this evaluation demonstrate that NASA Earth science data could make important contributions to surveillance programs trageting crop and food security.

Book excerpt: The use of Siamendments to manage plant disease incommercial soybean fields mayreduce production costs by reducing the number of fungicide applications. The time delay observed by soil Si amendment use may lead to ASR control practices that can benefit both, organic and conventional soybean production systems.
