Despite the research effort put into controlling pathogens, pestsand parasitic plants, crop losses are still a regular feature ofagriculture worldwide. This makes it important to manage the cropappropriately in order to maximise yield. Understanding therelationship between the occurrence and severity of attack, and theresulting yield loss, is an important step towards improved cropprotection. Linked to this, is the need to better understand themechanisms responsible for reductions in growth and yield inaffected crops.Physiological Responses of Plants to Attack is unique because itdeals with the effects of different attackers - pathogens,herbivores, and parasitic plants, on host processes involved ingrowth, reproduction, and yield. Coverage includes effects onphotosynthesis, partitioning of carbohydrates, water and nutrientrelations, and changes in plant growth hormones. Far from beingsimply a consequence of attack, the alterations in primarymetabolism reflect a more dynamic and complex interaction betweenplant and attacker, sometimes involving re-programming of plantmetabolism by the attacker.Physiological Responses of Plants to Attack is written anddesigned for use by senior undergraduates and postgraduatesstudying agricultural sciences, applied entomology, cropprotection, plant pathology and plant sciences. Biological andagricultural research scientists in the agrochemical and cropprotection industries, and in academia, will find much of use inthis book. All libraries in universities and researchestablishments where biological and agricultural sciences arestudied and taught should have copies of this exciting book ontheir shelves
