The document discusses pesticides and their classification. It begins with an introduction defining pesticides as toxic substances used to control bacteria, fungi, or insects that harm crops, plants, animals, or humans. Pesticides are often classified based on the type of organism they target. The document then discusses the need for pesticides to protect crops from pests and disease. It provides examples of common pesticide types including fungicides, herbicides, insecticides, and bactericides and describes their uses and targets. In summary, the document outlines pesticides, their benefits in agriculture, and their general classification categories.

2. Introduction
Pesticide, any toxic substance used to kill Bacteria, fungi, or insects that
cause economic damage to crop or ornamental plants or are dangerous
the health of domestic animals or humans. All pesticides interfere with
normal metabolic processes in the pest organism and often are classified
according to the type of organism they are intended to control.
(See herbicide; insecticide; fungicide; Bactericide

3. PEST
 Pest an insect or other small animal that harms or destroys garden plants, trees, etc
Needof Pesticides
 protect crops from insect pests
 Insect Eating and destroying crop
 Insects carrying disease

4. BENEFITS OF PESTICIDES
 Controlling pests and plant disease vectors
 Improved crop yields
 Human lives saved and disease reduced. Diseases controlled include
malaria, with millions of lives having been saved or enhanced with the use
of DDT alone
 Animal lives saved and disease reduced
 Tree/brush/leaf hazards Wooden structures protected
 using of pesticides in agricultural field to get good quality of food and
vegetables.
 pesticides help people to yield good food for them as well as source of
economy

6. Fungicide
 any toxic substance used to kill or inhibit the growth
of fungi. Fungicides are generally used to control
parasitic fungi that either cause economic damage
to crop or ornamental plants or endanger the health
of domestic animals or humans.
uses
 protect agricultural crops from spoiling
 prevent the spread of disease
 protect seeds from rotting in the ground

7. Herbicide
 an agent, usually chemical, for killing or inhibiting the growth of
unwanted plants, such as residential or agricultural weeds and invasive
species. Most herbicides are considered nontoxic to animals and
humans, but they can cause substantial mortality of non target plants
and the insects that depend on them, especially when applied aerially.

8. Insecticides
 Substances which are used to kill insects are called insecticides.
Insecticides have a wide application in the field of medicine,
agriculture, and industry. They have the potential to alter ecosystem
components majorly and are toxic to animals as well as humans.
Some insecticides become concentrated as they spread in the food
chain

9.  A bactericide is an application or
product that helps stop bacterial
infections in plants. There are
many commercially available
bactericides on the market;
some are designed for use with
outdoor plants, and others are
designed specifically for indoor
growing applications.
