Pesticides are chemical substances used for mitigating pests.Biopesticides are biological pesticides, created by growing and concentrating naturally occurring organisms
and their metabolites including bacteria and other microbes, fungi,
nematodes, proteins, etc.
Biopesticides are specifically microbial biological pest control agents that are applied in a way akin to chemical pesticides.

Biopesticides are specifically microbial biological pest control agents that are applied in a way akin to chemical pesticides.
Biopesticides for use against crop diseases have raised
themselves on a variety of crops. For example, biopesticides
play an important role in controlling downy mildew diseases. Their
benefits include a pre-harvest interval ,
the ability to use under moderate to severe disease pressure, and the tendency to use as a tank mix or in a rotational program with other
registered fungicides.
A major growth area for biopesticides is in the area of seed treatments and soil amendments. Fungicidal and biofungicidal seed treatments are used to control soil borne fungal pathogens that cause seed rots, damping-off, root rot
and seedling blights. They can also be used to control internal
seed–borne fungal pathogens as well as fungal pathogens that are on the
surface of the seed. Many biofungicidal products also show capacities to
stimulate plant host defenses and other physiological processes that
can make treated crops more resistant to a variety of biotic and abiotic stresses.
Advantages-
- Harmful remnant are not visible.
- Will stay cheaper than chemical pesticides when locally produced.
- Can be worth conventional and effective than chemical pesticides on long term basis.
- It is biodegradable in nature.

- Unsuitable if a pest outbreak is an immediate threat to a crop as it is slow in its processing.
- High specificity which may require an exact identification of the pest/pathogen and the use of multiple products to be used; although this can also be an advantage in that the biopesticide is less likely to harm species other than the target.
The global market for biopesticide was valued at $1.3
billion in 2011 and is expected to reach $3.2 billion by 2017, growing
at a CAGR of 15.8% from 2012 to 2017. North America dominated the global
biopesticides market, accounting for around 40% of the global
biopesticide demand in 2011. Europe is expected to be the fastest
growing market in the near future owing to the stringent regulation for
pesticides and increasing demand from organic products.
