Abstract

Anyone who has ever planted a garden knows not only the rewards of beautiful flowers, fruit, and/ or vegetables, but also the disappointment when plants become diseased or damaged. Many factors cause plants to exhibit poor vigor, changes in appearance, or even death. Both abiotic (non-living) and biotic (living) factors can negatively impact plant heath. Disorders that result from non-living factors (such as nutrient deficiencies, over/under watering, temperature stress, and chemical damage) are discussed in subsequent chapters. This chapter focuses on those living organisms that cause disease: fungi, water molds, bacteria, viruses, nematodes, phytoplasmas, and parasitic plants.
