2. Agrochemicals:
Agrochemicals refer to a broad category of chemicals used in
agriculture to enhance crop production and protect plants from pests,
diseases, and weeds.
There are several types of agrochemicals, such as
Fertilizers: Fertilizers provide essential nutrients to plants.
Pesticides: Pesticides are used to control and manage pests.
Plant Growth Regulators (PGRs): PGRs are chemicals that influence
plant development and growth processes.

3. CHARACTERISTICS OF Agrochemicals:
Here are some key characteristics of agrochemicals:
Efficacy
Selectivity
Persistence
Mobility
Toxicity
Bioaccumulation

4. CHEMICAL PESTICIDES:
Chemical pesticides are substances that are used to control, repel, or
kill pests such as insects, weeds, fungi, and rodents.
Types of Chemical Pesticides:
Insecticides: Target and control insects.
Herbicides: Control weeds and unwanted plants.
Fungicides: Combat fungal diseases in plants.
Rodenticides: Kill or control rodents.
Molluscicides: Control snails and slugs.
