"All common problems suffered by Australian plants are covered as well as many that are not so common. Each pest is listed with its physical description, regional occurrence, host plants, habits and control methods. The emphasis is on natural rather than chemical control so that your plants and garden benefit from minimal ecological interference. You will find information on: integrated pest control; pest feeding habits; beneficial insects; parasitic plants; nutritional deficiencies and toxicities; spraying equipment."--BOOK COVER.
Over the last fifty years, there has been an increasing recognition that eucalypts are vulnerable to a wide range of diseases. They have suffered destructive epidemics, particularly of dieback caused by the cinnamon fungus in native forests, of foliar diseases and cankers in plantations, and of dieback of remnant trees on agricultural and grazing land. This has stimulated intensive research into the causes and management of diseases of the eucalypts. This work represents a comprehensive review of our current knowledge of the health and diseases of eucalypts.
Amateur and professional gardeners, horticulturists, commercial nurseries and students will find this book invaluable. Pests, Diseases and Ailments of Australian Plants is an authoritative reference on pests, diseases and nutritional disorders of Australian plants, with the authors beingacknowledged experts in this field. This book describes over 300 introduced and native pestsand diseases. To find out what pest or disease is causing a problem, simply check the chart for symptoms. Each symptom is cross-referenced to the text, with colour photographs and detailed line drawings of pests, insect life cycles and damage symptoms on plants to help identify yourproblem. All common and uncommon problems suffered by Australian plants are covered in this book, with each pest being listed with its physical description, regional occurrence, host plants,habits and control methods. The emphasis is on natural rather than chemical control sothat your plants and garden benefit from minimal ecological interference.
Plant bugs--Miridae, the largest family of the Heteroptera, or true bugs--are globally important pests of crops such as alfalfa, apple, cocoa, cotton, sorghum, and tea. Some also are predators of crop pests and have been used successfully in biological control. Certain omnivorous plant bugs have been considered both harmful pests and beneficial natural enemies of pests on the same crop, depending on environmental conditions or the perspective of an observer.As high-yielding varieties that lack pest resistance are planted, mirids are likely to become even more important crop pests. They also threaten crops as insecticide resistance in the family increases, and as the spread of transgenic crops alters their populations. Predatory mirids are increasingly used as biocontrol agents, especially of greenhouse pests such as thrips and whiteflies. Mirids provide abundant opportunities for research on food webs, intraguild predation, and competition.Recent worldwide activity in mirid systematics and biology testifies to increasing interest in plant bugs. The first thorough review and synthesis of biological studies of mirids in more than 60 years, Biology of the Plant Bugs will serve as the basic reference for anyone studying these insects as pests, beneficial IPM predators, or as models for ecological research.
The present book consist of 30 reviews on important pest and diseases of cash, cereals, oilseed, vegetables, fodders, fruits and pulses etc. Most of these articles have been prepared by authorities in their receptive areas. There is worldwide swing to the use of ecologically safe, environment friendly methods of protecting crops from pests and pathogens.
Studies in the Agricultural and Food Sciences: Plant Breeding for Pest and Disease Resistance presents a critical review of the development of resistant varieties of plant to pests and diseases. It discusses the economic impact of pests and diseases; the methods of controlling these pests and diseases; and the challenges being faced by a plant breeder. Some of the topics covered in the book are the general principles and methods of breeding for resistance; importance of parasite variability to the plant breeder; methods of testing for resistance; requirements for successful inoculation; production of resistant varieties; and economic importance of fungal diseases; and variability in fungal pathogen. Pathogenic fungi and fungal diseases are also covered. The control of fungal diseases by resistant varieties is discussed. An in-depth analysis of diseases in plants is provided. The characteristics of bacteria and bacterial diseases are also presented. A chapter is devoted to epidemiology of diseases associated with mycoplasma-like organisms and rickettsia-like organisms. The book can provide useful information to farmers, botanists, students, and researchers.
