This invaluable resource introduces the eleven types of organism that cause
plant disease, ranging from higher plants to viroids and describes examples of
cash and staple crop diseases that have caused human catastrophes. Early
chapters cover serological and molecular techniques for the diagnosis of plant
pathogens, epidemiology, methods for estimating disease severity and its effect
on crop yields and techniques for limiting inoculum. Later chapters are
concerned with colonisation of the plant and symptom development and the
underlying biochemical and genetic factors that control these events. Finally,
the control of plant disease using a variety of techniques including genetic
modification is discussed. Modern diagnostic techniquesEpidemiology and the
measurement of
