Book Description
Recent Highlights in the Discovery and Optimization of Crop Protection Products highlights the most prominent, recent results in the search for safe and effective new crop protection products. With a focus on the design, synthesis, optimization and/or structure-activity relationships of new chemistries targeting insect, disease, weed, nematode, vector and animal parasite control, the book also includes recent developments in crop enhancement chemistries and new approaches to crop protection products. The inclusion of information on testing tools, green chemistry approaches, and the latest discovery tools, like modeling, structure-based design, and testing tools makes this volume complete. Based on key presentations given at the 14th International IUPAC conference on Crop Protection, May 19-24, 2019 in Ghent, Belgium, this book includes the many exciting new discoveries and findings reported. It is designed to inspire additional research and advancement in the field. - Based on science presented at the 2019 International Union of Pure and Applied Chemistry Conference on Crop Protection - Provides real-world perspectives on pesticide and disease control progress - Presents scientific developments from an international array of contributing authors

Book Description
Pesticides continue to provide an important tool in integrated pest management (IPM) programmes. Hitherto IPM programmes have had a strong bias towards insect control, but farmers need to control weeds, plant pathogens and other pest problems.This book follows the author's successful “pesticide application methods” by relating the equipment needs to the overall pest control requirement of major crops. It outlines the pest problems against which farmers are using pesticides and focusses on the details of the application techniques they need to optimise pesticide use.Much attention is now being given to genetically modified crops, but these do not necessarily avoid the use of pesticides. Some are engineered to be resistant to certain herbicides, so the use of these herbicides will still require careful application in order to minimise environmental side effects. Similarly, crops engineered for resistance to certain insect pest species may remain susceptible to other pests, thus emphasising the need for crop monitoring and careful use of any chemicals to avoid disrupting biological control.

Book Description
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

Book Description
PESTICIDE APPLICATION METHODS Pesticide Application Methods is the standard work for all those involved in crop protection. This fully revised and expanded edition provides up-to-date information on the different types of application techniques and how they should be used to ensure efficient and effective pest control. The third edition of this excellent book was published more than 10 years ago, since when a number of important developments have taken place. Examples include changes to legislation both in the EU and USA concerning water quality. This has an impact on how spray is applied and, more particularly, how the sprayer is designed to minimise quantities that remain in the equipment when spraying is completed, and in addition inform how and when the sprayer is cleaned. Concern about spray drift has also continued and has led to more research on how to reduce the amount of spray that moves downwind from a treated area. Important new information on this topic is included within the new edition. Professor Graham Matthews has been joined by two new co-authors to increase the breadth and depth of coverage in this updated edition of Pesticide Application Methods. This important new edition is a commercially significant reference tool and will be of great use and interest to all those working in crop protection, including agricultural entomologists and plant pathologists, pesticide scientists, advisors and consultants, large-scale growers, agricultural and horticultural scientists, agrochemical industry personnel including those involved in equipment supply and product formulation. Libraries in government and commercial research establishments, universities and agricultural colleges where agricultural and biological sciences are studied and taught should have multiple copies of this definitive book on their shelves.

Book Description
The hemlock woolly adelgid (HWA, Adelges tsugae Annand) is causing widespread decline and mortality of eastern hemlock trees (Tsuga canadensis (L.) Carr.). Stem injection of insecticide is widely used as a control measure, but its effectiveness depends on individual tree hydraulic characteristics. Recent work has shown that eastern hemlock daily water use is exponentially related to tree diameter, with smaller-diameter trees using significantly less water than largerdiameter trees. In this study we modeled daily water use for 20 eastern hemlock trees across a range of diameters. Based on expected daily water use and, thus, potential xylem transport of insecticide, we applied a dosage estimated to achieve a lethal and uniform xylem sap concentration of imidacloprid to half the trees (xylem transport treatment), and treated the remaining half based on the manufacturerrecommended dosage (MFR treatment), which is a linear function of tree diameter. At 4 and 56 weeks after treatment, we assessed all trees for the presence or absence of new shoot growth and live HWA population density. We found that both treatment dosages significantly reduced live HWA populations; however, 4 weeks after treatment, live HWA population density was 32 percent lower (LSMEANS) on xylem transport treatment trees compared with MFR treatment trees (treatment by time interaction, P = 0.006). Both treatment dosages also significantly increased the proportion of new shoot growth; however, over time xylem transport treatment trees had a significantly greater increase in new shoot production compared with MFR treatment trees. We conclude that dosages based on a xylem transport model not only significantly improved tree health more than the trees receiving the current recommended dosage, but also caused greater reductions in the live HWA population. Improving treatment dosages would reduce treatment cost, nontargeted effects, and would allow land managers to treat a greater number of trees.

Book Description
Food security is one of the primary themes of the United Nations’ Sustainable Development Goals. In this regard, agricultural engineering is considered the backbone of agriculture, and agricultural mechanization is considered a helpful way to enhance crop yield and farmers’ profitability. Technology in Agriculture presents research in the field of agricultural engineering technologies and applications in agricultural equipment engineering, biosystem engineering, energy systems engineering, and computers in agriculture. It provides an overview of recent advancements in agricultural engineering and examines key aspects of emerging technologies and their applications. In addition, the book explores modern methodologies such as artificial intelligence and machine learning for agricultural mechanization.
