The procedure of management is different in respect of the principal component: (a) Eradication or reduction of inoculum. INTRODUCTION TO THE INTEGRATED DISEASE MANAGEMENT (IDM): The integrated disease management (IDM) involves the need based use of pesticide only when the disease incidence reach economic threshold levels and this will promote the build up of many bio-control agent in the crop ecosystems. Much like diseases of humans and other animals, plant diseases occur due to pathogens such as bacteria, viruses, fungi, oomycetes, nematodes, phytoplasmas, protozoa, and parasitic plants. (c) Prevention through legislation (i.e., keeping the pathogen away from the host) by quarantine, etc. They do, however, produce symptoms such as ringspots, mosaic pattern development, leaf yellowing and distortion, as well as deformed growth. The biological agents that causing diseases to plants are known as pathogens. This type of management pro­gramme to control plant diseases is called Integrated Disease Management i.e., IDM or Integrated Pest Management i.e., IPM. What remains unclear is if; 1) plants pre-exposed to a short period of repetitive MS can prime defence responses upon subsequent challenge with necrotrophic pathogens, 2) MS mediates plant immunity via jasmonic acid (JA) signalling, and 3) a … PLANT DISEASES 2. Goals / Objectives General objectives are (1) to identify and evaluate potentially important diseases to include pathogen identification (etiology) and disease biology regarding occurrence, development and spread, and (2) to evaluate disease management practices.
