Pesticides are substances used to destroy organisms that are harmful to cultivated plants or animals. The document discusses the main types of pesticides - insecticides, herbicides, fungicides, and rodenticides. It provides examples of each type and how they are used. The benefits of pesticides include improving crop productivity and protection. However, pesticides can also negatively impact human health, the environment, and other organisms if misused. The document concludes with recommendations to prevent exposure to harmful pesticides.

A substance used for
destroying insects or other
organisms harmful to
cultivated plants or to
animals.

Pesticides are
classifies into
many classes
depending on
different criteria.
But some of the
subclasses of
pesticides are-
Types of Pesticides

4. 1.Insecticides
 Insecticides are substances used to kill
insects.
 They include ovicides and larvicides
used against insect eggs and larvae,
respectively.
 Insecticides are used in agriculture,
medicine, industry and by consumers.

5. 2. Herbicides
 Pesticides which are used to destroy unwanted weeds
in the crop are called herbicides.
 Selective herbicides kill specific weeds and leave the
desired crop unharmed.
 Some plants produce natural herbicides.
 Herbicides are widely used in agriculture.

6. 3.Fungicides
 There are many fungi which are responsible for
producing plant diseases. Chemicals which destroy
such fungi called as fungicides.
 Ex. Bordeaus which is mixture of lime, CuSO4 and
H2O.
 Fungi can cause serious damage in agriculture
resulting in losses of yield, quality and profit.

7. 4.Rodenticides
 Rodenticides are pest control chemicals which are
used to kill rodents (Rats/Mice).
 Rodents are usually difficult to kill with poison
because there feeding habits are like scavengers.
 They will eat small bit of something and wait, and if
they don’t sick, they continue.

8. Use of Pesticides
 Improving productivity
 Protection of crop losses
 Vector disease control
 Quality of food
 Other areas- Transports, sport complex,
building

9. Health effects of pesticides
The short-term adverse effects pesticides
exposure on human health are-
 Stinging eyes
 Rashes
 Blisters
 Skin irritation
 Blindness
 Nausea
 Dizziness
 Diarrhea and death

10.  Pesticides can contaminate
soil, water, turf, and other
vegetation.
 In addition to killing insects
or weeds, pesticides can be
toxic to a host of other
organisms including birds,
fish, beneficial insects, and
non-target plants.

11. Prevention from harmful pesticides
There are six main way to prevent us from pesticides these are: -
1) Buy organic and locally grown fruit and vegetables.
2) Wash fruits and vegetables before eating.
3) Know which fruits and vegetables have higher levels of
pesticide residue.
4) Grow your own produce.
5) Use non-toxic methods for controlling-insects in the
home and garden.
6) Have a ‘no shoes’ policy in your home.
