Q. What are three kinds of non-point source pesticide pollution? | A. The three kinds of non-point source pesticide pollution are runoff, run-in and leaching. Runoff occurs when rainfall or irrigation rates exceed the rate at which water can be absorbed into the soil. When runoff occurs, pesticide residues can be carried off the field and into surface waters. Run-ins is the transport of pollutants to groundwater by a direct route, such as through a sinkhole or an abandoned well. Leaching occurs when contaminants are carried through the soil with excess water that percolates below the crop root zone and into the groundwater. Leaching is most common in sandy, permeable soils.

species? Q. What type of pesticide containers are accepted for recycling? You must have a free copy of Adobe Acrobat® Reader for viewing PDF files, please visit Adobe. Resources found at Clemson University

Q. Define economic injury level in livestock pest control.
A. Economic injury level in livestock pest control means the
lowest number of pests that will cause damage equals the cost of preventing
that damage.
Q. How might lack of sanitation affect pest control?
A. Sloppy feed handling and overfilled watering facilities create
breeding areas for flies.
Q. What are reasons for difficulty in controlling livestock
pests?
A. Difficulty in controlling livestock pests may be caused by
poor understanding of the pest's biology, application in the wrong
place, or at the wrong time or inattention to label mixing and use
directions.
Q. Explain ways to prevent or reduce pesticide accidents.
A. Methods to reduce pesticide accidents include following label
instructions and storing pesticides safely.

Q. What is a convenient way to control horn flies?
A. A convenient way to control horn flies is through the use
of backrubbers.
Q. How do face fly adults feed on cattle?
A. Face fly adults feed on cattle by consuming tears, saliva
and nasal mucus.
Q. What area of cattle should be treated when using sprays to

Q. What are some biological control agents for flies?
A. Parasitic wasps, predatory beetles, and parasitic beetles
are biological control agents of flies.
Q. What should the minimum air temperature be when using knockdown
treatments for fly control?
A. When using knockdown treatments for fly control, apply when
the flies are relatively inactive and there is a minimum air temperature
of 70 °F.
Q. Why should manure spraying not be done routinely?
A. Manure spraying should not be done routinely because it destroys
beneficial mites and insects and it increases likelihood of insecticide
resistance.
Q. What type of fly are backrubbers most effective for?
A. Backrubbers are most effective for the control of horn flies.
Q. When is chemical control of horse flies most effective?
A. Chemical control of horse flies is most effective when dust
bags and backrubber oilers are used on the back and upper body.
Q. How should an insecticide be used when blow fly larvae attack
animal wounds?
A. An insecticide should be used to treat the infested wounds
and surrounding skin when blow fly larvae attack animal wounds.
Q. At what pressure should louse control sprays be applied?
A. Louse control sprays should be applied at 200-250 psi unless
otherwise specified.
Q. How many pairs of wings do ticks have?
A. Ticks do not have wings.
Q. 'Ear canker' in cattle is caused by what type of tick?
A. 'Ear canker' in cattle is caused by spinose ear tick.
Q. What are some nonchemical aids to tick control?
A. Reducing rodent population in pastures, reducing shrubs and
trees in pastures, and late-spring burning of pastures, where allowed,
are all nonchemical aids to tick control.
Q. Insecticidal ear tags will help control what kinds of ticks?
A. Insecticidal ear tags will help control spinose ear tick
and the Gulf Coast tick.
Q. What are some dairy insect management techniques used to
control pests of dairy cattle?
A. Proper construction, screening and caulking, and chemical
insecticides as well as sanitation practices are dairy insect management
techniques to control pests of dairy cattle.
Q. Horn fly control insecticides are most effective when applied
on what part of the animal?
A. Horn fly control insecticides are most effective when applied
on the back line and upper sides of the animal.
Q. Why are dust bags not effective against face flies?
A. Dust bags are not effective against face flies because the
animals tend to duck under them.
Q. Stable fly control insecticides are only effective when applied
to the legs and belly as what form?
A. Stable fly control insecticides are only effective when applied
to the legs and belly as sprays.
Q. What is the basis for all other control measures for stable
flies and house flies?
A. Rigorous sanitation, including frequent manure disposal is
the basis for control of stable flies and house flies.
Q. What are types of nonchemical control measures for fly control
on dairy operations?
A. Parasitic wasps, electrocutor traps, and sticky traps are
types of nonchemical control measures for fly control on dairy operations.
Q. What objects may residual sprays in dairies be applied to?
A. Walls and fences are places where residual sprays in dairies
may be applied.
Q. What type of mange represents a severe skin disease and is
quarantinable?
A. Psoroptic mange is a severe skin disease and is quarantinable.
Q. How do black flies (turkey gnats) feed?
A. Black flies feed by lapping eye secretions.
