Pesticidal Plants

The global biodiversity and climate emergencies demand transformative changes to human activities. For example, food production relies on synthetic, industrial and non-sustainable products for managing pests, weeds and diseases of crops. Sustainable farming requires approaches to managing these agricultural constraints that are more environmentally benign and work with rather than against nature. Increasing pressure on synthetic products has reinvigorated efforts to identify alternative pest management options, including plant-based solutions that are environmentally benign and can be tailored to different farmers’ needs, from commercial to small holder and subsistence farming. Botanical insecticides and pesticidal plants can offer a novel, effective and more sustainable alternative to synthetic products for controlling pests, diseases and weeds. This Special Issue reviews and reports the latest developments in plant-based pesticides from identification of bioactive plant chemicals, mechanisms of activity and validation of their use in horticulture and disease vector control. Other work reports applications in rice weeds, combination biopesticides and how chemistry varies spatially and influences the effectiveness of botanicals in different locations. Three reviews assess wider questions around the potential of plant-based pest management to address the global challenges of new, invasive and established crop pests and as-yet underexploited pesticidal plants.

As in previous volumes, readers will find a multidisciplinary forum for communicating knowledge related to the botany, horticulture, and pharmacology of herbs, spices, and medicinal plants. While magical and mystical powers have been associated with these plants through the ages, continued investigations in such areas as production, nomenclature, uses, chemical constitution, and dynamics help elucidate the affiliated chemical and physical processes that contribute to their unique flavor, fragrance, pharmacological, and other bioactive properties. This collection of articles examines the potential of natural products as pesticides, the richness of the Chinese Pharmacopeia, the similarities of Eastern Asian and Eastern North American medicinal plants, the use of borage as a source of gamma linolenic acid, and the botanical nomenclature of medicinal plants.

This book has been mainly written for the research workers and students of various Universities, who are interested to use eco-friendly indigenous plant materials in pest management programme. The book provides a brief amount on different plants having pesticidal properties viz., plant taxonomy, geographical distribution, chemical constitutions and their structural formula, their mode of action, procedure for preparation and their safety to non target organisms. It is hoped that this book will be very useful to graduate/post graduate students of Agriculture as well as Basic science, researchers and extension workers. This book will be useful to environme- ntalists who are interested to minimize the use of synthetic chemicals in pest manag- ement programme and also for the pesticide formulation industries to develop newer molecules based on phytochemicals. Every attempt has been made to provide necessary information for students and researchers, which is hardly available in other books.

This work is a comprehensive information on the indigenous bioresources of North Eastern India with the scope of bioprospecting for discovery and commercialization of new sources and products and long-term ecological balance. The exploration, conservation and sustainable utilization of bioresources of world’s Megabiodiversity Hotspots are undeniable. North Eastern India is a recognised biodiversity hot spot where the evolutionary forces are at its optimum, making this region as centre of origin for many species. Although little bit exploratory studies have been conducted in this part of the globe but a scientific exploitation of the bioresources is almost lacking. Unscientific exploitation and overexploitation without proper knowledge of the bioresources may lead to imbalanced ecosystem of this mega diversity region. At the same time, very less exploration and exploitation will hamper biodiversity based development. Today, unscientific dramatic changes are underway in this region. Human activities are changing, degrading and destroying the bioresources in an unplanned manner. Scientific bioprospecting of the bioresources will boost the economy while ensuring conservation. This book offers comprehensive information about various levels of bioprospecting of the gene pool of this Indo-Burma Mega Biodiversity Hot Spot, the North East India, which is endowed with huge biodiversity potential for exploration and exploitation for the benefit of humankind. Also, this book highlights the less and merely explored part of the indigenous biodiversity of North East India with explanation towards their better sustainable exploitation for benefit of the people, economy and environment. The novelty of the book lies in expert coverage of the bioresources of this mega-diverse region including plants, microbes, insects etc. with provisions for their sustainable scientific utilization. This book portrays North East India as a melting pot of bioresources which are little explored and also those resources which are still to be explored. The book mainly highlights the bioprospecting approaches for North East Indian bioresources, and thus, it make itself a unique one in filling the knowledge gap that is there regarding the bioprospecting of the biodiversity of this special region on the earth. The book concludes by the ecotourism potential of this region. The target audiences for this book include biodiversity economists who are working on technology and bioresource management issues, and especially on biotechnology and biodiversity, development economists addressing the issues of bioresources in developing countries. These people may be in academia, in government, in non-governmental organizations and in private companies. The other target audiences group is policy scholars in government/public sectors who are interested in issues of biotechnology, IPRs, and biodiversity. In addition, scholars/experts in both development studies and resource management studies form another group of target audiences. Also, the book will be useful for the interaction between developed and developing nations regarding the issues of biodiversity and bioprospecting, as North Eastern India is the hub of Biodiversity.

Pest and disease management continues to challenge the agricultural community. The rise in new pest and crop problems juxtaposed with public concern over pesticide use and more stringent environmental regulations creates the need for today's agricultural producers to stay current with new technologies for producing quality crops profitably. Biological and Biotechnological Control of Insect Pests presents an overview of alternative measures to traditional pest management practices, utilizing biological control and biotechnology. The removal of some highly effective broad-spectrum chemicals, caused by concerns over environmental health and public safety, has resulted in the development of alternative, reduced risk crop protection products. These products, less toxic to the environment and easily integrated into biological control systems, target specific life stages or pest species. Predation - recognized as a suitable, long term strategy - effectively suppresses pests in biotechnological control systems. Biological and Biotechnological Control of Insect Pests covers these topics and more. It explores the current approaches in alternative solutions such as: biological control agents, parasites and predators, pathogenic microorganisms, pheromones, botanical insecticides, genetic control, genetic engineering of plants and biocontrol agents, and government regulations for biocontrol agents and recombinant DNA technology. This book will be a useful resource to entomologists, agronomists, horticulturists, and environmental scientists.
