These pesticides listed above are chemical formulations intended for
preventing, destroying, repelling or mitigating their respective pest
group. It is also a mixture of substance that can be used as a plant
regulation, defoliant and desiccant, and it can kill potential
disease-causing organisms.
Pests are considered undesirable
and destructive because they are organisms that are harmful to us. Some
of these pests eat our crops, while some spread diseases. Herbs are
considered pest as well because they grow in the wrong places.
1.3HISTORICAL BENEFITS AND DANGERS
1.3.1BENEFITS
One may stand to ask, why can’t all the farmers just grow their food organically?
The
world population is 5billion and growing, of those about 700million is
undernourished. Over one-third of our food is lost to pest and without
pesticide incorporation; the losses will probably be even higher. So it
will be very difficult to feed the world organically. The answer
unfortunately, is that with current agricultural methods and
technologies, it is not possible to produce the quantities currently
needed for the number of people living in the earth surface. Pesticide
allows us to increase our harvest and feed more people.
In
addition to applications in agriculture, pesticides have many other
important uses. Many pests transmit diseases which are very dangerous to
us. For example, in the past, malaria was one a serious disease that
killed millions of people globally, to fight this problem, the use of
pesticide DDT was incorporated to kill mosquitoes which transmitted the
diseases. It was successful and the number of people who died from
malaria reduced drastically.
In the US, million of people
have allergic reactions to the cockroaches in their homes, pesticides in
insect sprays and baits helped reduced this problem a lot.
1.3.2DANGERS
Presently,
we are using more pesticides than ever. Although most modern pesticides
are much safer than their predecessors, a few of our commonly used
pesticides are toxic.
Researchers indicated that youngsters in homes
where household and garden pesticides are used are seven times as likely
to develop childhood leukemia. Of the 80,000 pesticides and other
chemicals in use today, 10% are recognized as carcinogeous. Farmers are
prone to certain cancers, including stomach prostrate and brain cancers
upon exposure to various kinds of toxic pesticides.
Another
NCI study found a link between breast cancer in women and elevated
levels of DDE, a metabolite of the pesticide DDT, in their fat tissue.
Women with the highest levels of exposure to DDT had four times the
breast cancer risk to women with the least exposure. In laboratory tests
where high doses of pesticides were given, researchers have observed
some significant health effects like genetic damage, reproductive
problems and possible links to cancer associated with pesticides.
As
pesticide issue is a very complex one, there is definitely a need for
certain pesticides in such areas as agriculture and disease prevention,
and yet there are also some obvious health risks from some of these
chemicals e.g. DDT. As a pesticide, DDT was first used during World War
II. It was first made in a laboratory in 1873 and also effective as an
insect killer that it was called the “atomic bomb†of pesticides. After
World War II, it was realized that DDT could be used on farms to control
some common agricultural pests. In addition, it was also used to
control certain insects which carried diseases like malaria and yellow
fever. By 1970, there were worries about DDT’s environmental and health
effects, as it is an extremely persistent pesticide. Finally in June
1972, the US Environmental Protection Agency (EPA) cancelled all the use
of DDT on crops and houses.

ABSRACT - [ Total Page(s): 1 ]In this production, it was aimed to review differences, abundance and effects of insects, to produce an environmental friendly insecticide and the judicious ways it can be used.Using laboratory and analytical methods which involves quantifying and reacting the chemical reagents. After test analysis, the insecticide was obtained by decanting method.The result of the product was tested for and the insecticide proved effective.In conclusion; the organophosphate chemicals used in this production tho ...
