Group 2 herbicides will occasionally get trapped on
the tank wall by petroleum-based formulations or
adjuvants, resulting in tank residues. Add detergent at
0.25
L/100 L to the ammonia rinse to prevent this
situation from happening. The detergent breaks down
the petroleum coating to allow the ammonia access to
the Group 2 product.
What to Do if Results Are
Unsatisfactory
•
Ensure the choice of pesticide(s) was suitable.
Are the treated crops and pests listed on the
product label(s)?
•
Compare your method of pesticide preparation
to the product label(s) instructions.
•
Check for equipment malfunction – e.g. plugged
screens, nozzles worn or mixed type or size.
•
Compare your application techniques with those
given on label(s) – e.g. stage of growth or
development of crop and pest(s), ground speed,
pressure and incorporation.
•
Consider weather conditions at application time
–
several labels include cautions against
application during weather extremes – e.g. cold,
heat, drought.
•
Consider time since application. Some results are
not apparent for several days. Look for early
symptoms of the chemical taking effect.
•
If results are unsatisfactory, seek technical help.
Gather all relevant data, particularly evidence such
as photos or specimens. Record wind, rainfall, soil
moisture condition, crop variety, fertility, quantity
of material used, acres treated and temperature at
time of spraying.
•
Document everything in writing. If crop damage is
involved, submit a specimen for diagnosis. Disease
or insect damage can resemble herbicide injury.
Pesticides and the Environment
Responding to a Pesticide
Related Concern
The
Environmental Protection and Enhancement Act
prohibits any person from causing adverse effects
when using pesticides. Farmers who witness or suspect
a pesticide drift or runoff that could affect their family,
pets or livestock or cause an adverse effect to their
shelterbelt, crop or their land should take the
following actions to protect themselves and assist in
an investigation that may result at a later date:
•
Immediately request family members to go into
the home to protect themselves from exposure.
Close all windows and air conditioning units in the
home. If they have felt spray settle on them, they
should immediately remove clothing and wash
exposed skin. If any physical symptoms develop,
then they should seek medical assistance or call
the Poison Centre at 1-800-332-1414.
•
Pets should be removed from the immediate spray
area or area where drift has occurred.
•
If livestock are at risk, the applicator should be
asked to stop the application until the livestock
can be removed or conditions change so the wind
is blowing away from the livestock.
•
If drift has occurred in the farmyard, then outdoor
furniture and play equipment should be washed
before use and garden produce, berry and fruit trees
should not be harvested or consumed but should be
monitored for unusual growth or discoloration. If
the produce shows signs of damage, it should be
destroyed. If berries or fruit trees show signs of
damage, the berries or fruit should not be eaten. If
no signs of damage occur after one to two weeks
(
depending on the pesticide), then all produce,
berries and fruit should be washed thoroughly.
•
Record as much detail of the application equipment
(
colour and type of spray equipment; make, model,
licence plate number, company information off
nurse trucks; colour, distinguishing features, call
numbers on the aircraft). If possible, take pictures.
•
Write down everything regarding what was witnessed
including date and time of occurrence, weather
