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:

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.
In accordance with University policy and Guidelines,
i an Examiner may grant an extension of the due date of an
assignment in extenuating circumstances;
ii no assignments will be accepted for assessment purposes
after assignments or model solutions have been released
except in extenuating circumstances;
iii assignments submitted after the due date without any
extenuating circumstances will attract a penalty of at
most 20% of the assignment mark for each working day
late;
iv students who submit an assignment after the due date and
wish to claim extenuating circumstances, must provide
documentary evidence with the assignment explaining
the circumstances;
v the unit examiner shall consider a claim for extenuating
circumstances and decide on the outcome;
vi the decision of the Dean shall be final in any dispute
that may arise in the implementation of these guidelines.
