Chemical Control of Plant Diseases
in Alberta
Introduction
Plants, like other living organisms, are attacked by
many diseases that are caused by fungi, bacteria,
viruses, mycoplasmas and nematodes. The management
of plant diseases is based on four general parameters:
•
Exclusion (quarantine): a disease organism or
diseased plant material is prevented from entering
a country or disease-free area where the disease
could become established.
•
Protection: includes management practices that
can be used to protect plants from disease
organisms. Examples include proper sanitation,
chemical controls, adequate soil nutrient levels and
good soil drainage .
•
Eradication: involves the use of crop rotations
or the application of chemicals such as fungicides
to control plant disease.
•
Plant breeding: results in the development of
crop plants that have partial or complete resistance
to a specific disease or range of infectious diseases.
Chemical control of disease
In Alberta, fungal diseases of some field crops may
be subject to direct chemical control by fungicides. At
present, foliar fungicides are registered for a number
of significant foliar diseases including the following:
Sclerotinia white mould, alternaria black spot and
blackleg control in canola, cereal leaf diseases, foliar
diseases of potatoes and pulse crops.
