Using Insecticides In The Battle Between The
Farmer And The Insect
If a vegetable is planted there is a nearby insect just
waiting to eat it. This eternal dance between farmer and insect
has been going on for centuries.

Usually however it is that insect that wins.
Throughout the ages there has been a constant battle between
the gardener and those pesky insects. Early on farmers came up
with means to control or eliminate insect infestations. Many of
our natural insecticides that are in use today were developed
and utilized by our ancestors.
It was discovered through trial and error that certain
plants were natural insecticides and provided some relief from
insect infestations. Often these natural insecticides were
combined with certain minerals such as arsenic, copper and
sulfur. Due to their lack of chemistry skills as this was a
budding science these methods did not normally work well.
Considering it was all done by trial and error the majority
of the results were unsatisfactory because of ineffective
application methods or the ratios were off possibly. The
ancient Romans would burn a mixture of sulfur and plants that
are natural insecticides. Apparently they would walk through
the fields with this smoking mixture and it would kill
insects.
With their primitive chemistry skills newly found minerals
are often added to the plants that are natural insecticides or
they would add things like arsenic into honey and then use this
to kill and control ants. Unfortunately adding too much of one
thing and not enough of another, never makes for good chemistry
and the majority of these methods are either ineffective or
potentially dangerous to humans and animals.
Around the late 19th century it was common practice for
farmers within the United States to use sulfur, copper
acetoarsenite, calcium arsenate or arsenic to control insects
within their fields. Although, these were not entirely
successful methods, more than likely due again to chemistry and
application issues.
The big boom in synthetic insecticides began after World War
II. These new chemicals, especially DDT, where not only
inexpensive but highly effective. DDT was a broad-spectrum
insecticide. Because it was so effective it became enormously
popular and its use was wide spread. Unfortunately it was not
known until many years later the detrimental effects it had on
humans and animals. It has since been banned from use within
the United States.
Since then many synthetic insecticides have been banned or
the very least deemed unsafe. This is probably due to the
advancement of technology and the scientific communities'
ability to study the long-term affects of the synthetic
chemicals used. It is no wonder that we are turning back and
looking at what nature has to offer.
Natural insecticides are once again being put on the front
lines against insect infestations. Some forms of natural
insecticides never fell out of use; the use of nicotine in its
highly concentrated form has always been used as a natural
insecticide, as well as the use of Pyrethums. Although many of
the synthetic chemical insecticides were designed after their
natural counterparts. So here we are, almost full circle and
once again we're looking to nature to provide us with the means
to win in the battle of man vs. insect. Ironic isn't it?
