4. Fertilizer is any organic or inorganic material of natural or
Fertilizers synthetic origin that is added to a soil to supply one or more
plant nutrients essential to the growth of plants.
Mined inorganic fertilizers have been used for many centuries, whereas
chemically synthesized inorganic fertilizers were only widely developed during the
industrial revolution. Increased understanding and use of fertilizers were
important parts of the industrial Green Revolution of the 20th century. Eg:
NH4NO3and CO(NH2)2.
Those fertilizers which are derived from organic plant
Organic Fertilizers or animal matter is called as Organic fertilizer.
Eg: Urea, manure, compost, etc.

Fertilizers matter is called as inorganic fertilizer.
Eg: NH4NO3, Ca(NO3)2, KNO3, etc.

causing harm and interfering with the production, processing, storage, transport
or marketing of food, agricultural commodities or substances which may be given
to animals for the control of pests on their bodies. Also used as substances
applied to crops either before or after harvest to protect the commodity from
deterioration during storage and transport.
Herbicides, also commonly known as weedkillers, are
pesticides used to kill unwanted plants. Selective herbicides
Herbicide kill specific targets, while leaving the desired crop relatively
unharmed.
An insecticide is a pesticide used against insects.
Insecticide Insecticides are used in agriculture, medicine, industry and
the household.
Fungicides are chemical compounds or biological
organisms used to kill or inhibit fungi or fungal spores.
Fungus's are a tiny plantlike organism that gets its
Fungicide nourishment from other living or nonliving things. It can
cause serious damage in produce, resulting in critical
losses of yield, quality and profit.

Herbicides have widely variable toxicity. In addition
to acute toxicity from high exposure levels, there is
concern of possible carcinogenicity.

10. 2,4-DICHLOROPHENOXYACETIC ACID
 2,4-Dichlorophenoxyacetic acid is a
common systemic herbicide used in
the control of broadleaf weeds.
 It is one of the most widely used
herbicide in the world, and the third
most commonly used in North
America.
 In 1987, the International Agency for
Research on Cancer (IARC)
concluded that 2,4-
dichlorophenoxyacetic acid be
classified as a class 2B carcinogen -
"possibly carcinogenic to humans".
