This document discusses insecticides, pesticides, and their uses. It notes that insecticides are chemicals used to kill insects at home, and are applied via spray guns or aerosol bombs. There are three main types: phosphates, carbomates, and DDT. Pesticides are poisons used in farms to control pests like stemborers and improve crop yields of rice, corn, and sugarcane. Pesticides are grouped into herbicides, insecticides, and fungicides which respectively kill weeds, insects, and fungi. The document asks questions about insecticide and pesticide use and effects.

1. SCIENCE VI
Subject Matter:
Insecticides and Pesticides

2. Science Concepts/Ideas:
• Insecticide is a chemical poison used to kill harmful
insects at home, such as cockroaches and mosquitoes. It
is applied with the use of spray guns and aerosol bombs.
• There are three basic types of insecticides, namely:
phosphates (malathion), carbomates, and DDT (
dichlorodiphenyltrichlorothane)
• Pesticide is a poison used in farms to effectively control
pests such as stemborers. The use of pesticide improves
the yield of crops such as rice, corn, and sugarcane.
• Pesticide is grouped into three, namely: herbicide,
insecticide, and fungicide. Herbicide kills harmful weeds.
Insecticides destroy harmful insects in plants. Fungicide
destroys fungi.

3. Developmental Activities:
• How do you get rid of insects like
mosquitoes and cockroaches at
home?
• How do farmers make their crop
grow healthy?

4. How to use insecticides and pesticides
1. From what you observe, how do they
maintain the proper use of pesticides and
insecticides?
2. Who uses those chemicals?

5. Analysis/ Discussion:
• Do you use insecticide at home? What kind of
insecticide do you use? Is there any harmful
effect that you observe when using it? Who
use pesticide? Where do they use it? What
does pesticide do with the crops? Is there any
harmful effect in the use of pesticide?

6. .
• Mang Berto noticed that the new
leaves of his mango trees are falling
and the santol leaves have black
spots on them. What should he do to
protect his trees?

7. Evaluation:
1. Why are pesticides used by farmers? Give at
least two reasons
2. Why is insecticide used at home? Give at
lease two reasons.
3.Name the brands of commonly used
insecticides and pesticides.

8. Assignment:
• Interview a farmer. Ask him what is the best
pesticide for him and why he uses it.
