The dilemma in using these powerful insecticides however is that they do not absorb in soil or water very easily, and thus are easily passed through different organisms and can eventually effect humans and other animals. If these chemicals were to get into a lake for example, and managed to be inhaled or eaten by fish, it could cause much death and disease, and if these fish were caught and eaten by humans,it could also be very dangerous. Mineral-based pesticides There are still some
effective biochemical pesticides that are very useful, and relatively
safe to humans and other creatures. Many of these are mineral-based
pesticides that are not as toxic as the power DDT, but are much safer
and still work well. One great counter to fungi is pure elemental
The seeds of the Pyrethrum plant are very effective "botanical pesticides," that are far less harmful than chemical pesticides.

The best botanical pesticides come from the pyrethrum plant, which is a type of chrysanthemum. The seeds of these plants contain a poison that is made into a dust, and can be sprayed onto plants. This poison also holds the chemical PBO, piperonyl butoxide, which does not allow insects to metabolize the toxin, effectively paralyzing them. However, this pesticide could cause some problems to water life in an aquatic area, so it is best used away from bodies of water.
A farmer sprays pesticides on his crops. In order to create
any successful society, there must be a strong agricultural backbone that
is able to produce enough food so that there is never a famine of any
kind. But, ever since there has been farming, there has been a war between
farmers and pests, and it is always imperative to have good BACK - HOME - BIBLIOGRAPHY |
