The Rural Voice, 1978-06, Page 21Health of Animals. Seaforth, reported that
if specific symptoms are listed and a pet
owner doesn't recognize the symptoms or
if the animal does not react in the
prescribed manner then the owner feels
that his pet does not have the disease. If
the animal acts out of the ordinary a vet
should be consulted.
The areas with the most recorded cases
are East WaWanosh, West Wawanosh and
Ashfield townships although other cases
have been reported throughout the county.
The scheduling of a rabies clinic in
Huron County is decided by Health of
Animals, the Huron County Health Unit
and the number of enquiries about having
a clinic, plus the number of diagnosed
rabies cases.
The cost of having a clinic is high and the
immunity gained from these immunization
shots lasts for dogs, between three and
four years. In cats, the immunity does not
last as long.
The only sure way to diagnose a rabies
case is to send the head of the animal in
question to the lab in Ottawa through
Health of animals in Seaforth and have it
tested.
Health of animals officer Dr. Thompson
pointed out that "It is too risky with
humans involved to go by diagnosis
without a lab result".
Weeds adjusting
to atrazine use
Atrazine. the weed killer that has helped
the spread of the corn industry in Ontario
in the last 10-1E years faces a new problem.
The first inkling of trouble came three
years ago when a Bruce County farmer
consulted crop scientists at University of
Guelph about an infestation of lamb's
quarter in his atrazine -sprayed corn field.
The weed killer had worked effectively
for more than 10 years and both the farmer
and Prof. John Bandeen of the department
of crop science found it difficult to believe
what was happening. But tests of the
Iamb's quarter seed confirmed the
farmer's fears.
About this time, Vince Machado
completed a PhD in horticultural science at
Guelph. working on the difference of
tomato varieties in genetic susceptibility to
nutrition which, like atrazine. is a member
of the triazine family of herbicides. He
continued at Guelph, working on the
problem of atrazine tolerance with
broad -leaf weeds in corn.
There was, by then. plenty to go on.
Farmers in four more counties reported
infestations of lamb's quarter in their corn
and there were later reports of broad -leaf
weeds such as redroot, pigweed, ragweed,
bird's rape and groundsel resisting the
herbicide in Ontario, Quebec and the
United States.
