Book excerpt: Citrus production is one of the world's largest agricultural industries. Surveys of the occurrence of nematodes attacking citrus show they are present in all citrus-growing countries of the world. The first report of and association between a nematode and citrus appeared in 1889 (673), but it was not until the discovery in 1912 of Tylenchulus semipenetrans Cobb, 1913, on the roots of citrus trees in California (965) that a nematode was found to cause a diseased condition of citrus later called slow decline.

Download or read book Potato Production Worldwide written by Mehmet Emin Calıskan and published by Academic Press. This book was released on 2022-10-22 with total page 492 pages. Available in PDF, EPUB and Kindle. Book excerpt: Potato is a crop grown on all inhabited continents of the globe. It is included in the top five crops of the world, used as staple food in several countries, and the number of people daily consuming the potato may surpass one billion. Despite the high quantities of seed potato produced worldwide, there are yield gaps due to challenges such as abiotic stresses, pests, climate change and poor production practices. A region-wide critical analysis of yield declining factors can help formulate management strategies that can improve potato yields. Bridging yield gaps in potato will ultimately ensure the role of this crop in securing current and future food security. Potato Production Worldwide presents information on this global crop from its history, morphology, and taxonomy to the growth and development of the potato crop, including the latest strategies in addressing today’s biotic and abiotic challenges. This book identifies the reasons for yield gaps in various potato production regions of the world, as well as presenting the best production practices, pest management strategies and approaches to deal with climate change from the perspective of potato production. Chapters provide important insights into potato production cultures and approaches in the major potato production countries. Potato Production Worldwide will be a valuable resource for researchers, scientists and students seeking a comprehensive view of successful potato production. Provides comprehensive information on the origin, history, taxonomy, morphology, ecophysiology, growth and development of the potato Addresses production practices, including irrigation, nutrient management, harvesting and post-harvest techniques Explores the impact of Abiotic stresses (drought, chilling, salinity etc.) and their management

Download or read book Environmental Impacts of Microbial Insecticides written by Heikki M.T. Hokkanen and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 275 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological pesticides are increasingly finding therr place in IPM and increasing numbers of products are making therr way to the marketplace. Particularly in China, Latin America and Australia, implementation is proceeding on a large scale. However, in the USA and Europe, registration procedures for insect pathogens to be used for insect control have been established that requrre low levels of risk, resulting in costs of retarding the implementation of microbial agents. This book provides a review of the state of the art of studies on the envrronmental impact of microbial insecticides. It originates from a Society for Invertebrate Pathology Microbial Control Division Symposium .. Assessment of envrronmental safety of biological insecticides", organised in collaboration with the EU-ERBIC research project (FAIR5-CT97-3489). This symposium was initiated by Heikki Hokkanen and Chris Lomer, and was held at the SIP Annual Meeting in 2001 in The Netherlands. The emphasis in this book is on large scale use of microbial agents for insect control, demonstrating how this use has been proceeding with minimal envrron mental impact. This book is intended to be of use to regulatory authorities in determining whether further studies in eertain areas are necessary and how to conduct them if needed, or whether sufficient information has been collected already to permit fuH registration of many of these biological control agents.
