This publication is a compilation of reports on all plant species and varieties that have been called either resistant or tolerant to infestation by the root knot nematode, Heterodera marioni (Cornu) Goodey, (formerly called H. radicola (Greef) Mueller). The purpose is twofold: to bring together all available information on the subject in condensed form for the use of growers, plant breeders, and other investigators, and to establish a basis for the contribution of further data. It must not be assumed that all of the plants listed here are recommended as resistant. They intention is rather to present technical source material, not only useful to those who need practical information on particular plants but also suggestive to future workers.

Ornamental trees, shrubs and flowers have always been extremely popular and in large demand. Whether in gardens or parks, common usage of alpines, bedding plants, cacti, cut flowers, house plants and pot plants, as well as herbaceous plants, ornamental grasses, shrubs and trees makes a definitive volume on their pests of essential value to entomologists and plant scientists. The fully revised and updated second edition of Pests of Ornamental Trees, Shrubs and Flowers follows up the successful previous edition with coverage of many new pests and highly detailed color photographs. The book opens with a review of the main features of insects, mites and other major pest groups. . Each major order and family of pests is considered in turn, with details of their status, host range, world distribution, diagnostic features and biology. Descriptions of the characteristic damage caused are also given. Contains coverage of more than 60 new pests and nearly 90 additional color photographs Discusses principles of pest control of ornamental plants, followed by sections on the various pests

Plant Parasitic Nematodes, Volume III provides a comprehensive discussion of the different advances in plant nematology. This includes biochemical techniques to taxonomy and innovation in transmission and scanning electron microscopy technology. It explains a broadened basis for understanding nematode physiology and behavior and the sensory mechanisms that govern nematode actions and plant host-nematode interactions. The book discusses the development of modern approaches to the evaluation and reduction of crop losses. The emphasis of this volume is on plant parasites and insights gained through research on other nematodes. In particular, the book explains the anatomical, developmental, behavioral, and genetic studies on the free-living nematode Cenorhabditis elegans, which is a widely used laboratory model for examining various biological problems. The information provided by various researches on C. elegans increases our understanding about the relevance of nematodes to general biological processes in higher organisms, including man. The book is divided into 19 chapters which cover the following concepts of plant nematology: biochemistry, cytochemistry, and genetics; morphology and function; host-parasite relations; and evaluation and control of crop losses. The present volume is an excellent reference for students, lecturers, and research professionals in plant parasitology and related fields.

This book contains 22 chapters, 2 appendices (of the nematicides and species mentioned throughout the book) and 24 colour plates covering all aspects of practical plant nematology in subtropical and tropical agriculture, including rice, cereals, sweet potatoes, root and tuber crops, food legumes, vegetables, groundnut, citrus, tree and fruit crops, coconut and other palms, coffee, cocoa, tea, bananas, sugarcane, tobacco, pineapple, cotton, other tropical fibres, spices and medicinal plants. It provides practical guidance on the methods of extracting, processing and diagnosing different plant and soil nematodes and on integrated nematode management. This book is intended for those studying and working in the area of crop protection.

Food Crop Production by Smallholder Farmers in Southern Africa: Challenges and Opportunities for Improvement evaluates traditional cultivation practices used by smallholder farmers, providing a synthesis of the latest information on increasing crop yield through adoption of research innovations. The book catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector including: management practices that reduce net carbon emissions; technologies that improve soil structures and conserve the natural resources base; means of empowering female resources along value chains; and government commitment to adopt policies that enhance agriculture productivity by encouraging farmers to use environmentally sound cultivation technologies. Traditional farming techniques often produce negative impacts on the environment and ecosystem resulting in outbreaks of diseases and pests. In addition to the region's recurrent droughts, these outbreaks of numerous diseases and pests, weeds and other invasive plants put thousands at risk of poverty and hunger, as well as malnutrition. This book presents enhanced agricultural production technologies for ensuring adequate food production, safety and nutritional quality for the population of Southern Africa and forms the basis for an increased SADC regional effort in food production through which financial and trade institutions can improve stakeholder capacities, encourage micro-enterprise development and enhance employment and regional trade. - Provides a critical synthesis of data and information for increasing crop yield through adoption of research innovations - Evaluates traditional and scientific interventions that address food security issues of the poor farmers in the region - Presents agro-ecologies of countries in the region and how they relate to various cultivation practices - Catalogs smallholder cultivation practices and recommends innovative strategies for improving the agriculture sector
