Define the term "Integrated Pest Management." List IPM tactics used in
turfgrass pest control.
Integrated Pest Management refers to the use of a combination of pest control
tactics. IPM programs use many types of techniques in a single plan or strategy
to reduce pests and keep their damage to an acceptable level. IPM tactics
include monitoring and early detection, sanitation, and cultural, mechanical
(physical), biological, and chemical
control methods.
What are some factors that influence the success of biological controls?
Biological control agents usually target specific pests. Biological control agents
must be able to move to - or be placed in contact with - the target pest. For
that reason,
application techniques influence success. Adoption of biological control
measures
usually takes careful planning and timing. Finally, biological control organisms
must be
able to tolerate conditions at the site. To be sustainable, they must persist from
season to season.
,What is biological control? Give one example.
Biological control involves using some aspect of the pest's biology to control
it. One example is the uyse of natural enemies, biological agents that control a
pest. Turfgrass managers can preserve or encourage natural enemies already
present in the system. Alternatively, they can introduce commercially
produced biological organisms.
Biological control also includes the use of pheromones or juvenile hormones to
control insects.
What is cultural control? List several cultural control tactics used in turf.
Cultural control measures disrupt the normal relationship between pest and host
in
order to prevent or suppress an infestation. Cultural controls make the pest
less likely to survive, grow, or reproduce. They can involve changing the turf
grass environment or its physical condition. Cultural control measures may
also change the behavior of a pest. In turf, variety selection and proper
establishment are basic cultural control measures.
Other practices employed in turf include thatch management and proper
mowing, watering, and fertilization regimes. Aerating soil and cultivation
practices that improve water infiltration (spiking, vertical mowing, or coring)
can help.
, What is mechanical control?
Mechanical controls use some mechanical device such as a trap or barrier to
control pests.
What is sanitation? Give two examples.
Sanitation is general cleanliness. Sanitation reduces the levels of pathogens and
other pests in the turf grass environment. Using pest-free seed, sprigs, or sod is
a sanitation strategy. Careful disposal of diseased clippings is another. So are
cleaning and
disinfecting tools and equipment, and taking care to avoid spreading disease by
foot traffic.
Why is the timing of a pesticide application important?
To be effective, pesticides must be applied correctly and at the proper time
and rate. In many cases, pesticides need to be used at a certain stage in a
pest's life cycle. Applying them too early or too late is a waste of time and
money. In addition, poorly timed
applications may pose a threat to the turf you intend to protect as well as
to other organisms and the environment.
Explain the difference between a preventative and a curative pesticide
application.
A preventative application is made before the problem appears. A curative
application is made after the problem is noticed.
