,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.
What are the effects of soil texture and organic matter content on 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.
