and water. These XXXXX factors may cause pest populations to increase or decrease
d d d d d d d d d d d d d
without influence from humans.
d d d d
Biological Control - Correct Answer - ....involves manipulating the natural enemies of
d d d d d d d d d d d
pests-those that kill and eat pests (predators), those that feed on but do not necessarily
d d d d d d d d d d d d d d d
kill pests (parasites), or those that cause diseases in pests (pathogens). You can
d d d d d d d d d d d d d
encourage and maintain high population levels of these natural enemies by using
d d d d d d d d d d d d
pesticides carefully or by releasing a pest's enemies into the target area.
d d d d d d d d d d d d
Cultural Control - Correct Answer - ....methods are the activities involved in taking care
d d d d d d d d d d d d d
of the plants, such as site selection and watering practices. These techniques can alter
d d d d d d d d d d d d d d
the environment around the plants to affect the pests that could be attacking them.
d d d d d d d d d d d d d d
Mechanical Control - Correct Answer - ....involves the use of equipment or manual
d d d d d d d d d d d d
operations to keep out or disrupt the life cycle of pests. Barriers that exclude pests
d d d d d d d d d d d d d d d
include fencing, plastic mulches, and row covers.

Host Plant Resistance - Correct Answer - ....Some plants can tolerate damage from
d d d d d d d d d d d d
certain pests or are unsuitable for pest development; this trait is known as xxxxxxxx.
d d d d d d d d d d d d d d
For example, the St. Augustine grass variety 'Floratam' is resistant to chinch bugs.
d d d d d d d d d d d d d
, Chemical Control - Correct Answer - ....involves the use of pesticides to destroy pests,
d d d d d d d d d d d d d
control their activity, or prevent them from causing damage. Chemical pesticides are
d d d d d d d d d d d d
often the quickest way to control pests and, in some cases, the only alternative.
d d d d d d d d d d d d d d
Plant Selection - Correct Answer - A critical step in pest control is to choose the proper
d d d d d d d d d d d d d d d d
plant or variety for the landscape. Choose all landscape plants according to their water
d d d d d d d d d d d d d d
requirements, shade tolerance, and susceptibility to pests.
d d d d d d d
Water - Correct Answer - Too much or too little xxxxx can damage or kill plants. Lack of
d d d d d d d d d d d d d d d d d
water causes leaves to wilt, droop and drop. Excess water in the soil forces out the
d d d d d d d d d d d d d d d d
oxygen that plant roots need to survive.
d d d d d d d
Fertilization - Correct Answer - Plants need 16 elements, which in horticulture are called
d d d d d d d d d d d d d
plant nutrients. The soil usually contains enough of these nutrients for normal plant
d d d d d d d d d d d d d
growth. Nitrogen is normally the most limiting plant nutrient. It constitutes the foundation
d d d d d d d d d d d d d
of most common fertilizers. The elements needed in tiny amounts are called
d d d d d d d d d d d d
micronutrients. The best way to determine how much and what kind of fertilizer that a
d d d d d d d d d d d d d d d
landscape needs is to take a soil sample.
d d d d d d d d
Mowing - Correct Answer - The primary cultural practice in turf management is xxxxx.
d d d d d d d d d d d d d
Good xxxxxxx practices enhance turf and can significantly help you manage pests. It
d d d d d d d d d d d d d
can improve turf color, density, root development, texture, and wear tolerance.
d d d d d d d d d d d
Thatch - Correct Answer - Thatch is the layer of undecayed grass between the soil and
d d d d d d d d d d d d d d d
green leaves of a turf plant. As old turf plants age and die, they decompose into finely
d d d d d d d d d d d d d d d d d
textured humus that becomes a part of the soil surface.
d d d d d d d d d d
Pruning - Correct Answer - A primary technique for producing a specimen plant is
d d d d d d d d d d d d d
xxxxxx. xxxxxx prevents and treats some diseases and helps keep some ornamental
d d d d d d d d d d d d
plants attractive. You must prune properly to prevent or minimize insect and disease
d d d d d d d d d d d d d
invasion. Do not make the cuts flush with a trunk or main branch. Instead, prune the
d d d d d d d d d d d d d d d d
limb outside the collar, which is the section of the branch where it joins to the trunk or
d d d d d d d d d d d d d d d d d d
main stem.

d d d d d d d d d d d
problem appears.

Reactive, or Curative Treatments - Correct Answer - Occur after you notice the pest or
d d d d d d d d d d d d d d
its damage. Then you can apply a pesticide that targets that specific problem.
d d d d d d d d d d d d d
Protecting Water Resources - Correct Answer - Do not use more pesticide than the
d d d d d d d d d d d d d
label directs.

d d d d d d d d d d d d d d d
link (such as a well) to groundwater.
