Book excerpt: With a changing global climate, plant pathologists must understand the impact aberrant weather events may have on the development of plant diseases. Fungal plant infections are largely dependent on temperature and precipitation, climate parameters that are predicted to change more in this century. Venturia inaequalis causes apple scab, one of the most destructive apple diseases of temperate growing regions. Temperature and precipitation drive apple scab infections and forecast models, which guide growers in efficient, effective fungicide applications. In some recent years in the Northeast, these models have failed to accurately predict when ascospores of this fungus are available to cause primary infections, prompting more fungicide intensive management. Identifying cause(s) of model failures will restore confidence in them, enabling growers to reduce fungicide use. As technology becomes an increasingly important component of on farm decision-making, so does educating new farmers and agricultural students in the benefits of Integrated Pest Management and challenges associated with models early on in their college educational experience. This research attempts to identify reasons for ascospore maturity model failures, determine to what degree critical ascospore maturity parameters have changed and create a tool that educators may use to engage undergraduate students in the complexities of Integrated Pest Management research and modern farming. It will more specifically do the following: 1) Dry periods will be analyzed to determine if frequency and duration are increasing, causing the fungus to mature over a longer period of time than models currently estimate. 2) Degree-days during fall and winter will be examined to estimate what effect a warming climate may have on ascospore and tree development, and ultimately apple scab occurrence. The research will use lab and field observations to track the development of V. inaequalis ascospores, the source of primary apple scab infections. These observations will be compared to infection events and spore maturation forecasts from models currently used by apple growers in the Northeast. 3) A case study developed for publication in American Phytopathological Societies' Plant Health Instructor will provide early career college students with an introduction to forecasting models, Integrated Pest Management and the challenges associated with climate variability.

Available in PDF, EPUB and Kindle. Book excerpt: Alternaria blotch of apples emerged in the late 1980s in North Carolina threatening the nations seventh largest apple producing state. Alternaria blotch, causal agent Alternaria mali, has since spread throughout the entire Southeast apple growing region. Alternaria blotch proved to be difficult to control with the management programs in place at the time. Filajdic et al developed a weather-based disease-forecasting model to aid in the timing of fungicide applications to manage the disease. However, this model was based on the use of iprodione (Rovral), which never became fully registered for use on apples. The purpose of this project is to improve the prediction of the onset and progression of Alternaria blotch to aid in the timing of fungicide applications. The ability of four Alternaria models for predicting the occurrence of Alternaria blotch was examined over three growing seasons. Five sites across the apple production area of Henderson County, North Carolina were established to track disease progress and collect weather information. The data collected on-site were compared to the output of the disease models generated from on-site weather data as well as geospatial satellite based weather data. The initial results of the project show that none of the examined models exhibit a strong correlation with either the onset or the progression of the disease. However, examining the individual disease model attributes revealed key information about the disease progression. The detailed model analysis suggests that the initial inoculum level, in addition to the increasing susceptibility of the host, most readily influences the progression of the disease over the course of a growing season. The traditional approach of plant disease model validations is usually limited in scope to counties, states, or regions. With the possible threat of bio-terrorist attacks on our nation's agricultural system, the ability to create and validate models on a national scale is of paramount.

Book Synopsis Plant Disease Forecasting Systems by : Dilip Kumar Chakrabarti
Download or read book Plant Disease Forecasting Systems written by Dilip Kumar Chakrabarti and published by Springer Nature. This book was released on 2023-05-10 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focus on creating popularity and interest in modeling, derivation of equations for plant disease forecasting or construction and use of Web-based Expert Systems among plant pathologists. This book covers descriptions of many historic plant disease epidemics, various forecasting systems and methods of their construction, instruments required for study of plant disease epidemics, widely used commercial forecasting systems and present global scenario of forecasting. In the human history plant disease epidemics have brought unsurmountable misery many a times. Still breaking out of epidemic in any time in any part of the world is a stark reality. The panic spraying of chemical pesticides is not a panacea. Only the IPM technology may give relief. This technology if backed by the disease forewarning system may yield the desired results. Hence, an in depth understanding of plant disease forecasting system and its successful implementation may bring the global food security. This title provides a useful background for all students, practitioners, and researchers interested in the field of epidemiology, food security and agriculture sciences.
Book Synopsis Experimental Techniques in Plant Disease Epidemiology by : Jürgen Kranz
Download or read book Experimental Techniques in Plant Disease Epidemiology written by Jürgen Kranz and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most books on epidemiology have treated the subject from a statistical, mathematical or computer applicational point of view. However, experiments must be performed first to provide the data for models which in turn can then be proven by further experimentation. This mutual interplay of theory and empirics gives epidemiology its scientific thrust and charm. This book provides a choice of methods for varying applications and objectives, covering all important aspects for the designing of experiments. Furthermore, the reader is supplied with solutions to his experimental problems and many "tricks of the trade". The newcomer to the field will also profit by this methodology guide.

Download or read book Biorational Tree Fruit Pest Management written by MartÃn Aluja and published by CABI. This book was released on 2009-01-01 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the human impact upon the environment becomes more apparent and severe, the need to develop agricultural techniques that cause minimal damage to the environment has increased. This is particularly the case in the area of pest management, where integrated pest management (IPM) strategies have become a fundamental component of plant protection. Focusing on insect pests of tree fruits and combining behavioural research with crop protection applications, this book emphasizes the importance of environmentally sustainable approaches in an agroecosystem. Both experimental and applied topics are discussed, including the conceptual framework of IPM, functional and behavioural ecology of a pest, host detection mechanisms and monitoring tool development, as well as pest management case studies. Representing a comprehensive discussion of tree-fruit pest management, from the evolution, ecology and behaviour of insect pests to the implementation of applied biorational programmes, this will be essential reading for researchers as well as commercial growers and extension agents.

Download or read book Apples written by Rafiya Mushtaq and published by CRC Press. This book was released on 2022-12-30 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to polymorphism, apples have extraordinary diversity. Depending on variety, apple fruits can differ in color, shade or size; apples even can be oval or pear-shaped. There are more than 10,000 varieties of apple, which vary in taste, shape, juiciness, texture, color, firmness and other qualities. For these reasons, apples have been diversely studied, and many improvements have been made such as the introduction of high density cropping; rootstock breeding; or varietal development. Therefore it is important to understand and document the production methods adopted and implemented in recent times for harvesting maximum benefits of the crop. Apples: Preharvest and Postharvest Technology documents production practices along with detailed illustration on varieties, rootstocks, important cultural practices and post-harvest management. This book will serve as a complete guide for apple production from farm to fork and will help students, scholars, researchers and scientists working in this domain. The book will also help growers all over the world to understand best practices for apple production, to harvest maximum yields, and in turn, to increase their returns.

Available in PDF, EPUB and Kindle. Book excerpt: Among the Horticultural Crops, Fruits and Vegetables (FV) are of primary - portance as the key source of essential components in an adequate and balanced human diet. FV have supported largely the daily food requirement of mankind since ages and even before man learned to grow cereal crops systematically. Over the years, growing FV has been the mainstay of rural economy and has emerged as an indispensable part of agriculture world over, offering farmers a wide range of crops in varied topography and climate. In certain parts of the world, FV are the major dietary staple. Apart from being a rich source of vitamins and minerals, this sector also contributes significantly in economy of the region or the nation. The increased income from per unit area of FV is far ahead and can not be compared with that of cereal crops. A recent survey by the Economist revealed that the world population has - creased by 90 % in the past 40 years while food production has increased only by 25 % per head. With an additional 1. 5 billion mouth to feed by 2020, farmers worldwide have to produce 39 % more. Looking at the load of the future food requirement, the global increased production of FV during last few years has absorbed the additional food requirement and accordingly the eating habits are also changing and shifting - wards more consumption of these commodities worldwide.
