What determines whether a given plant is a weed? - Answer A
weed is any
unwanted
plant
What are the two main goals of weed management? - Answer The primary
goal is to minimize weed competition and the other main goal is to limit
the weed's reproduction in order to manage the weed population in years
to come.
Distinguish grasses from broadleaf plants and herbaceous from woody
plants - Answer Grasses are considered monocots, meaning they have a
single seed leaf, they also have narrow leaves with parallel veins and a
fibrous root system. Broadleaf plants have two seed leaves and are
therefore called dicots, they have broad leaves with veins that form a net
patterns. Broadleaf plants can be further classified into herbaceous and
woody, where the woody plants have a thick layer of dense tissue called
bark, which herbaceous plants lack.
Describe the life cycles and propagation of annual, biennial, and perennial
plants - Answer Annual plants live for less than a year, they produce many
seeds in one growing season, and then die. Summer annuals winter as
seeds, and winter annuals winter as a low-growing plant, both summer
and winter annuals are easiest to control when they are small. Biennial
plants live for two growing seasons, they germinate from seed in the
spring or summer and winter as a rosette of leaves. They flower in their
second year, produce seeds and then die. Both annuals and biennials
reproduce only by seed. Perennial plants live for at least 2 years and
sometimes longer, they may reproduce by seed or vegetatively through
several different mechanisms.
What is needed to kill annual, biennial, and perennial weeds and when is it
easiest to do so? - Answer To kill annuals or biennials, you must kill the
whole shoot. Controlling these weeds with tillage or herbicides will kill
them plus stop seed production, which will reduce future weed problems.
The most effective way to kill perennials is to destroy the underground
vegetative structures by either repeatedly tilling the soil or by using a
herbicide that translocates to destroy all of the plant parts.
How should you time herbicide application with respect to a plant's life
cycle and which timing is most effective? - Answer All weeds may start as
seedlings and it is most effective to treat the plants at this stage because
less energy is required to kill the plants at this stage than at any other.
Biennials and Annuals are controlled by a fall or early spring treatment,
and perennials are controlled best with a fall treatment as well.

Questions With Correct
Answers!!
application of soil
herbicides? - Answer Soil organic matter and clay particles can adsorb
soil-applied
herbicides, meaning more herbicide will be required in these types of
soils because
the herbicide will be bound to the soil particles and will not be
available to be
absorbed by the
weeds.
How do you keep soil herbicides from moving off target? - Answer Do not
apply herbicides to areas where they may leach into groundwater, or run
off into water sources or cropping areas. Also avoid applying herbicides to
areas where desired tree and shrub roots may extend and DO NOT apply
herbicides to frozen soils.
How and when should you apply soil herbicides? - Answer Soil treatments
are commonly used when a site requires residual non-selective control,
such as electric transformer stations, rail ballasts and signpost bases.
They can be applied any time that the soil is not frozen, and some soil
applied herbicides need to be transported by rain to be absorbed by the
plant.
When are foliar sprays appropriate and not appropriate? - Answer Foliar
sprays are
not recommended for large brush because of the potential for drift.
Foliar sprays
should be operated from the ground close to the plant and can either
be applied
through broadcast or spot
application.
What are the factors in timing a foliar spray? - Answer Foliar treatments
can be made from the time the leaves are fully expanded until they begin
to turn color in the fall, but are most effective when applied to fully
developed foliage of an actively growing plant. They should be applied at
a temperature between 60 and 80 degrees F, and should have adequate
time to soak into to plant, thus applying right before it rains is ineffective.
How are adjuvants used most effectively? - Answer Adjuvants may be
necessary to
use for better absorption by foliage that is extremely
waxy or hairy.
What are the similarities and differences between foliar, cut-surface, and
basal bark applications? - Answer Foliar applications are put directly onto
the foliage of a growing plant. Basal bark applications are used to control
shrubs, canes and thickets or trees up to 5 inches in diameter and are

applied to the lower 18 inches of the stems. Cut-surface treatments are
used to control plants with thick bark or when they have trunks larger
than 5 inches in diameter at the base.
Define and explain "pesticide". - Answer A pesticide is any substance used
to directly control pest populations or to prevent or reduce pest damage.
Pesticides can range from anything such as an insecticide to a herbicide
to a fungicide.
What is the difference between organic and inorganic? - Answer Organic
means the
compound contains the element carbon, it does not mean it is
natural. Inorganic
means that the it is derived from minerals that occur
in nature.
What is the difference between the different types of pesticide names? -
Answer Chemical name: complies with accepted guidelines established by
chemists. Common name: normally appear on the label before or above
the chemical name and refers to an active ingredient.
Trade name: the name given by the manufacturer, appears in large
letters at the top
of the
label
Compare selective and non-selective herbicides: - Answer Selective
herbicides only harm certain plants and leave others unharmed. Non-
selective herbicides are toxic to most or all plants.
What are the uses and characteristics of contact and systemic herbicides?
- Answer Contact herbicides do not move within the plant, they are
sprayed on and only kill the parts of the plant they actually touch.
Systemic herbicides are absorbed through leaves or roots and then mover
or translocate within the treated plant.
What are the effects and uses of plant growth regulators? - Answer Plant
growth regulators do not kill plants, but are used to increase, decrease, or
change in some fashion the normal growth and or reproduction of the
plant. They may be used to retard plant growth and reduce the need for
other chemical or mechanical management measures.
Describe the function of inert ingredients: - Answer They do not possess
pesticidial activity but are added to improve application effectiveness,
safety, handling, storage or other characteristics of the final product.
