This book was released on 2017 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tomato spotted wilt virus (TSWV) and late leaf spot (LLS), caused by Cercosporidium personatum, are important diseases affecting peanuts (Arachis hypogaea L.). One of the most promising ways to combat these diseases is with resistant cultivars created through the development of recombinant inbred lines allowing for the discovery of resistance genes. These mapping populations can be very large making phenotyping time consuming and difficult; the objectives of this research aim to increase the efficiency of phenotyping methods. Field experiments were conducted to compare genotypes from multiple mapping populations for resistance to the two diseases as well as evaluate the use of unmanned aerial systems (UASs) and their ability to increase efficiency when phenotyping TSWV and LLS. Juvenile plants were also evaluated for resistance to LLS. Results indicated that some populations showed more resistance to disease than other and UASs proved to be helpful in the phenotyping of mapping populations. Parental lines evaluated were also susceptible to infection by C. personatum at a very early age.

This book was released on 2019 with total page 450 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spotted wilt disease, caused by the thrips-vectored Tomato spotted wilt virus (TSWV), is an important disease affecting peanuts in the southeastern United States. Peanut Rx is a risk index that allows growers to determine and avoid combinations of production practices that are conducive severe spotted wilt epidemics. However, the intensity of spotted wilt disease varies among fields having the same risk category depending on location and year as documented in this study. To account for the variability in spotted wilt intensity, a 'thrips risk factor' was created based on location- and year-specific predictions of peak thrips dispersal from the 'Thrips Infestation Predictor Tool for cotton'. A 'modified Peanut Rx' was developed through the integration of the 'thrips risk factor' into the risk index which provided a better risk assessment than Peanut Rx. With it, peanut growers can directly account for the thrips vector in assessing their risk of spotted wilt in order to determine the suitable production practices that would help them avoid severe epidemics and yield losses.

Download or read book Thrips Biology and Management written by Bruce L. Parker and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 606 pages. Available in PDF, EPUB and Kindle. Book excerpt: Thrips (fhysanoptera) are very small insects, widespread throughout the world with a preponderance of tropical species, many temperate ones, and even a few living in arctic regions. Of the approximately 5,000 species so far identified, only a few hundred are crop pests, causing serious damage or transmitting diseases to growing crops and harvestable produce in most countries. Their fringed wings confer a natural ability to disperse widely, blown by the wind. Their minute size and cryptic behavior make them difficult to detect either in the field or in fresh vegetation transported during international trade of vegetables, fruit and ornamental flowers. Many species have now spread from their original natural habitats and hosts to favorable new environments where they often reproduce rapidly to develop intense damaging infestations that are costly to control. Over the past decade there have been several spectacular examples of this. The western flower thrips has expanded its range from the North American continent to Europe, Australia and South Africa. Thrips palmi has spread from its presumed origin, the island of Sumatra, to the coast of Florida, and threatens to extend its distribution throughout North and South America. Pear thrips, a known orchard pest of Europe and the western United States and Canada has recently become a major defoliator of hardwood trees in Vermont and the neighboring states. Local outbreaks of other species are also becoming problems in field and glasshouse crops as the effectiveness of insecticides against them decline.

Download or read book Virus and Virus-like Diseases of Major Crops in Developing Countries written by Gad Loebenstein and published by Springer Science & Business Media. This book was released on 2013-12-18 with total page 831 pages. Available in PDF, EPUB and Kindle. Book excerpt: It appears that a comprehensive and up-to-date book on the impact of virus diseases on the major crops in developing countries is now much needed, especially as there have been rapid advances in the biological and molecular characterization and detection of the pathogens and possible approaches for their control. On the other hand, the economic losses caused by many of these diseases are tremendous and much of the accumulated knowledge to diminish the crop losses has not filtered through, or cannot be applied. This book is focused on the important crops. Each chapter on a specific crop will include inter alia, geographical distribution, the viruses - symptoms, damage, detection - a brief description of the viruses concerned, and present and future ways for their control. Experts from India, Nigeria, UK, USA, France, Germany, Peru, Japan, Australia, Netherlands, Venezuela, Kazakhstan and Israel (many of them from the International Research Institutions) have contributed chapters to this book.
Download or read book Seasonal Occurrence and Epidemiology of Tomato Spotted Wilt Virus and Frankliniella Fusca (Hinds) (Thysanoptera: Thiripidae) with Emphasis on 3 Peanut Genotypes in North Carolina written by and published by . This book was released on 1904 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of the research has been to further the understanding of the seasonal occurrence of tomato spotted wilt virus (TSWV) and the insect vector, Frankliniella fusca, in relation to North Carolina peanut production. Emphasis was placed on 3 Virginia-type peanut genotypes, NC-9, NC-V11, and NC-12C, which were included in field and greenhouse experiments to determine relative disease and thrips levels and their interactions. These are components of a larger strategic goal to develop management strategies that can minimize future impacts of TSWV and be compatible with peanut production in North Carolina. Research was conducted to determine the winter, spring, and summer occurrence of F. fusca in NC peanut fields. Thrips movement in spring was significantly influenced by prevailing wind direction. No thrips were collected on sticky traps during days when maximum temperature did not exceed 18.7 C.F. fusca, caged with TSWV infected peanut plants in August, 1996 and sampled in March, 1997, were analyzed for the presence of TSWV by ELISA. A single thrips tested positive for the virus. In another experiment, three Virginia-type peanut genotypes were monitored for the incidence of TSWV symptoms and the presence of F. fusca at 3 locations in NC's peanut producing area. Overall disease incidence at the 3 locations was 6%. Of the genotypes, NC-9 ranked the highest in disease incidence (7%), followed by the genotypes NC-12C (6%), and NC-V11 (5%). F. fusca counts were greatest on NC-V11, followed by NC-9 and NC-12C. A comparison of the survival and reproductive success of F. fusca on TSWV infected and uninfected plants of the 3 genotypes was conducted under greenhouse conditions in NC. Effects of genotype and virus by genotype interaction were not significant. However, TSWV infected plants had significantly fewer adult and larval F. fusca than did uninfected plants.
