Plant Pathology Overview

What is the primary focus of Plant Pathology?

Which of the following is NOT a physiological activity of a healthy plant?

Which of the following represents a way in which pathogens cause disease in plants?

What is a key objective of studying plant pathology?

Which of the following describes a mechanism by which pathogens weaken plant tissues?

Plant Pathology (Phytopathology)

Phytopathology is the science of plant diseases, aiming to improve plant survival.
Derived from Greek "Pathos" (suffering) and "logos" (study), it involves studying plant disease nature, development, and control.

Healthy Plant Physiological Activities

Normal cell division, differentiation, and development
Water and nutrient uptake from soil
Photosynthesis for food synthesis
Xylem and phloem transport of water and food
Metabolism of synthesized materials
Reproduction

Pathogen Impact on Plants

Pathogens disrupt plant processes using various mechanisms:
- Utilizing host cell contents
- Causing cell death or metabolic disruption via enzymes, toxins, and growth regulators
- Weakening tissues by nutrient loss
- Disrupting food, mineral, and water translocation

Objectives of Plant Pathology

Investigating biotic (living), abiotic (non-living), and environmental factors causing plant diseases.
Studying pathogen mechanisms in disease development.
Analyzing plant-pathogen interactions within the environment.
Developing disease control methods to minimize losses.
