Methods of Weed Control
Weed Control Methods Overview
(using a combination of lecture
and visual aids):
Cultural Control:
Explanation: This involves changing
farming practices to reduce the
environment in which weeds thrive.
Examples include crop rotation,
selecting weed-resistant crops, and
proper spacing. Visual Aid: Show
images of crop rotations or cover
crops.
Mechanical Control:
Explanation: This involves
physically removing or cutting
weeds. Examples include mowing,
tilling, or hand-pulling. Visual Aid:
Show images of tillers or hand tools
used for weeding.
Chemical Control (Herbicides):
Explanation: The use of chemical
herbicides to kill or inhibit weed
growth. Discuss both selective and

CONTROL
Tilling:
Explanation: Tilling
involves turning the
soil to uproot weeds
and incorporate them
into the soil.
Visual Aid: Show
images of tilling
equipment (e.g.,
rototillers, plows).
Advantages: Effective
for controlling deeprooted weeds.
Disadvantages: Can
damage beneficial soil
organisms, lead to
soil erosion, and may
promote weed seed
germination if

Hands-On
Weeding:
non-selective herbicides. Pros and
Cons: Quick results, but concerns
about chemical runoff and harm to
the environment. Visual Aid: Show
images of herbicide application.
Biological Control:
Explanation: Using natural
predators or pathogens (like insects,
goats, or fungi) to control weed
populations. Pros and Cons:
Sustainable but may take time and
effort to manage. Visual Aid: Show
examples of biological control
agents.
Integrated Weed Management:
Explanation: Combining multiple
control methods for more effective
and sustainable weed management.
Example: Using cultural practices in
combination with herbicides or
biological control methods. Visual
Aid: Diagram showing integration of
multiple methods.
Mulching and Ground Covers:
Explanation: Using organic or
plastic mulches to prevent weeds
from getting sunlight or from
sprouting. Visual Aid: Show images
of mulched garden beds.
overdone.
Mowing:
Explanation: Mowing
cuts weeds at ground
level, preventing them
from flowering and
spreading seeds.
Visual Aid: Show
images of mowers
(e.g., push mowers,
ride-on mowers).
Advantages: Quick
and easy for
controlling weeds in
lawns and grassed
areas.
Disadvantages: May
need to be done
repeatedly to keep
weeds from
regrowing.
Hand-Pulling:
Explanation: Handpulling involves
manually removing
weeds from the soil,
usually by the roots.
Visual Aid: Show
images of hand tools
like hoes and weed
pullers.
Advantages: No
chemicals involved,
very effective in small
garden areas.
Disadvantages: Timeconsuming and laborintensive for large
areas.
Hoeing and Weeding:
Explanation: Using
hoes or other tools to
cut or scrape weeds
from the soil surface.
Visual Aid: Show
images of different
types of hoes (e.g.,
stirrup hoes, garden
hoes).
Advantages: Can
cover large areas
relatively quickly,
doesn't disturb soil
structure as much as
tilling.
Disadvantages:
Requires physical
effort and skill for
effective weed
removal.
Flame Weeding:
Explanation: Flame
weeding uses a
propane torch to burn
weeds, especially in
cracks or between
rows of crops.
Visual Aid: Show
images of flame
weeders.
Advantages:
Environmentally
friendly, quick, and
effective for killing
small weeds.
Disadvantages: Only
effective on young,
small weeds and
requires careful
handling to avoid
fires.
Pros and Cons of
Mechanical Weed
Control:
Create a table on the
board listing the
advantages and
disadvantages of each
method discussed.
Lead a class
discussion on when
each method might be
most useful. For
example, when would
hand-pulling be
better than tilling, or
when might mowing
be better than
hoeing?
G. Finding practical
applications of
concepts and skills in
daily living
Group Activity:
Divide the class into small groups
and give each group a different
scenario (e.g., large farm, home
garden, urban landscaping, etc.).
Each group discusses and decides
on the best methods of weed control
for their given scenario.
Encourage students to use the
methods discussed and weigh the
pros and cons for each.
Group Presentations:
Each group presents their chosen
weed control methods to the class.
Group Discussion /
Scenario-Based
Problem Solving:
Divide the class into
small groups and
give each group a
different scenario
(e.g., a large farm
with extensive weeds,
a small home garden,
a community park).
Ask the groups to
decide which
mechanical weed
control methods
would work best for
their scenario and
explain why.
Allow for questions and discussion
after each presentation.

I. Evaluating learning
Directions: Read each question
carefully and choose the letter of the
correct answer.
1.What is cultural weed control, and
how does it differ from other
methods of weed management?
A) It involves the use of chemicals to
kill weeds.
B) It focuses on modifying
farming practices to discourage
weed growth.
C) It uses biological agents like
insects to control weeds.
D) It focuses solely on the use of
physical tools to remove weeds.
2.How can crop rotation help in
reducing weed populations?
A) It limits the types of weeds
that can grow by constantly
changing the environment.
B) It uses herbicides to kill weeds
after every crop season.
C) It plants only one crop every year
to weaken weed roots.
D) It ensures weeds are watered less
frequently.
3. Why is selecting weed-resistant
crop varieties an effective cultural
method for weed control?
A) It prevents weeds from
competing with the crops for
water and nutrients.
B) It eliminates the need for
herbicides entirely.
C) It forces weeds to adapt, reducing
their growth.
D) It ensures that only the crops
survive, leaving no room for weeds
to grow.

the flowers and
seeds of weeds,
limiting their
ability to spread.
C) Mowing helps
fertilize the soil and
promote weed
growth.
D) Mowing provides
shade to prevent

V. REMARKS
VI. REFLECTION
Reflect on your teaching and assess yourself as a teacher. Think about your students’ progress this week. What works?
What else needs to be done to help the students learn? Identify what help your instructional supervisors can provide for
you so when you meet them, you can ask them relevant questions.
Teaching about different types of weeds was fun and practical. Students learned how weeds like dandelions,
crabgrass, and aquatic weeds affect gardens and farms. They connected the lesson to real-life examples of weeds
they see in their own yards.
