The first half of this unit introduces students to fungi as one of the most important plant pathogens. The second half of the unit deals with the principles of plant pathology, taking examples from fungal and other pathogens. These studies provide a useful facet of learning for applied plant biology students.
The lectures and practical sessions on classification provide a basis for identification of fungi through further reference to the readily available literature. The plant pathology section includes the concept of a plant disease, basic causes of disease, host defence systems and disease resistance, environmental effects on disease manifestation, and symptomatology and control of plant diseases.
On completion of this unit students will be able to:

1 Students are required to actively participate in at least eighty
percent of the practical classes in this unit. A student must
obtain a pass (i.e. 50%) in both theory and practical components
of the unit.
2 In accordance with University's Assignment Extension Policy
(Regulation 5.9), the examiner of a unit may grant an extension
of the due date of an assignment in extenuating circumstances.
This policy may be found in the USQ Handbook, the Distance
Education Study Guide and the Faculty of Sciences' Orientation
Handbook for new on-campus students. All students are advised to
study and follow the guidelines associated with this policy.
3 Closed Examination: a closed examination is an examination where
the candidates are allowed to bring only writing and drawing
instruments into the examination.
