पेस्टीसाइड, इन्सेक्टीसाड्इस- रसायन विज्ञान, सामान्य विज्ञान Video Lecture | सामान्य विज्ञानं (General Science) for UPSC CSE in Hindi

hello friends this video on
environmental issues part 17 is brought
to you by exam feel calm no more fear
from exam so now the next objects which
I finished for you using crop
productivity that is insecticides and
pesticides
now with manuals and fertilizers what we
try to do is we try to improve the
quality of the soil we try to provide
more nutrient to the plants so the pluck
so that the plant can grow where the
plant can give more productivity so that
is our motto
but when we talk about insecticides and
pesticides our motto is different we
don't want anything to harm that plant
so we want to protect the plants that is
a motto so that is why we apply
insecticides to protect the plant from
insects we apply pesticides to protect
the plant from pests so that the crop
productivity is not harmed
now these insecticides and pesticides
can kill non-target organisms also so
that is one bee minute now why do we
give insecticides for example it is
suppose this is the plant okay and we
are spraying insecticides on this why
are we staying insecticides to kill the
insects which are harming this plant but
sometimes what happens is this
insecticide because insecticide is
nothing but some poisonous substance
which can kill that particular insect
now sometimes that poisonous substance
might be poisonous for some other
organism also so that is it can kill
non-target organisms as well excessive
use can lead to soil or water pollution
again well when we spray it all the time
if it directly or indirectly it should
go to soil now once it reaches the so I
have one hoop to swine because they are
nothing but harmful and poisonous
chemicals so when these chemicals reach
the soil it is going to affect the
organisms present in the soil it might
affect the composition of the soils it
might affect the soil textures of the
soil quality gets affected so this gives
to soil pollution no one is poison
soil it is very easy to reach water as
well because whenever there is soil
erosion the soil gets carried away and
it reaches the water bodies and was the
water pollution so here you can see so
the soil at the plant they are linked
very closely related right so this can
also adversely affect the food chain so
when I say that what my home is let us
suppose a spray this is I have on this
plaque right so from the plant very
easily gets into the soil so if it also
reaches the soil some part of the
insecticide of the pesticide in the soil
are present small insects and so on
walks like hawks
now this artworks are eaten up by bigger
insects so that is it get the boys
engaged inside the body builder insects
these enzymes might be eaten up by birds
so the poison actually enters the food
chain from one organism to another
organism it can destroy the soil
ecosystem because see in any ecosystem
if a poison or toxic substance enters so
obviously the ecosystem gets adversely
affected that is quite obvious so the
same thing happens here so ants a poison
reaches the soil spend is why the
ecosystem gets destroyed
so now considering all these pros and
cons what is advice these these is to go
for organic farming so what is organic
farming so organic farming is firing
with no chemicals for with minimum use
of chemicals now we cannot say that yes
we can do fine without using chemicals
absolutely but that is possible I didn't
say that is not possible
but looking either
kind of requirement which we have in
terms of crops so the amount of
production which we want so we have to
achieve that also so considering that
sometimes minimum use of chemicals is
required but what we I do is we can
avoid using chemicals as much as
possible so this type of filing is
called organic farming so you would have
observed in your neighborhood that if
you go to buy some organic vegetables or
organic fruits they are pretty more
expensive when compared into normal
foods and vegetable spend that's because
the normal fruits and vegetables are
with the help of insecticides pesticides
etc so they might have those chemicals
inside them but in organic farming you
are safe so they are all done without
use of chemicals so maximum use of
manuals in organic farming because
basically manuals and fertilizers they
do the same thing just that fertilizer
was being strong chemicals onion is more
effective than manuals
healthy cropping patterns so the way the
cropping is being done for example in
one season one crop is growing in the
other season some other crop is grown so
that they won't complement each other so
some proper walking patterns are being
followed so that crop productivity
increases thank you please visit
