Introduce the basics of plant pathology, providing a historical background and relevance to current plant issues.. Illustrate the difference between abiotic and biotic plant problems and the different organisms that cause plant diseases.. What’s the attraction?. Plants are a rich source of nutrients for many organisms including bacteria, fungi, protoctista, insects, and vertebrates…. Do plants have an immune system?. Plants do not have an immune system comparable to animals…. Year 9. . – The Knowledge – Science – . Spring . 2. 2. . Types of Disease. Types: . Bacteria – may produce poisons (toxins) that damage tissues and make us feel ill. Virus – can only survive inside our cells. They use our cells to reproduce causing cell damage.. What is a plant disease?. A plant . disease. is any abnormal condition that alters the appearance or function of a plant. It is a physiological process that affects some or all plant functions.

A science-based, vegetable seed industry initiative to standardize the identification of plant pathogen strains and races based on sets of host differentials and reference plant pathogen strains. Foliar application of various chemicals leads to alterations in the rhizosphere micro flora by changing the pattern of root exudates. . The pattern of the rhizosphere microflora i.e. numbers and species composition can be changed by various factors, such as:.
