Introduction

Pest control Pests are organisms that reduce the quality or yield of a crop or plant (Biology AS textbook, Indge, Rowland, Baker). Pest control uses various techniques to eliminate populations of specific pests to increase productivity of crops. The two most common methods are the use of Pesticides and Biological Pest Control. This essay will show how and why Biological Pest Control is favoured over the use of Pesticides. Biological Pest Control is the use of a specifically chosen organism to eat, kill, or otherwise harm a particular pest, and often referred to as 'natural enemies' according to the article Biological Control of Pest; www.smartgardening.com/Biological_Pest_Control.htm. These organisms may be predators, parasites, or a disease, which will attack the harmful insect. Biological Control is used as a programme usually in conjunction with Pesticides in PMI, once the effects of Biological Control show the dosage of pesticides is considerably lowered which works as an advantage for Biological Control. ...read more.

Middle

A famous example of the use of Biological control is that of the Ladybirds appetite for aphids, they are regarded as beneficial insects for controlling a variety of plant pests. A pesticide is a substance intended for preventing, destroying repelling or mitigating a pest. Pests can be insects, mice and other animals, unwanted plant, fungi, micro-organisms like bacteria and virus, as well as insects. The term pesticide includes herbicides, which kill weeds, fungicides target fungi that cause many plant diseases, and insecticides, used to combat insect pests. The few benefits of Pesticides are that they are specific to an organism so humans and beneficial organisms go unaffected by the use of pesticides. Pesticides are biodegradable, this means it will break down quickly in the soil, and it's chemically stable so it has a long shelf life. Pesticides start to work immediately once applied. Pesticides have to pass stringent safety tests before they can be applied, according to Biological Review Volume 10 and Number 2 November 1997. ...read more.

Conclusion

As stated by Chemistry In The Market Place 4th Edition, by Ben selinger. In conclusion the use of Pesticides is highly unethical for society, not only for the well being of humanity but all living species. The long-term damage done is far worse then the short-term benefits, economically, environmentally and socially. It is irresponsible to design pesticides which are fatal to the entirety of the natural world for the sake of making a profit. Scientific research should be used in order to find alternative methodology in Pest Control rather than developing new Pesticides. Therefore it is my opinion that Biological pest Control is far more advantageous than the use of Chemical Pesticides. In the future if Pesticides continue to have the same effect as they do today on the environment then Pesticides should either be banned or have stricter regulations imposed, as there is an alternative available, which is just as effective; Biological pest Control. ...read more.

    Pesticides were often used repeatedly over the course of many years consecutively. This would very often result in the pest becoming resistant to the pesticide.

    Secondly there are systemic fungicides e.g. propiconazole and benomyl. These have protective properties against fungal diseases. After absorption by plant roots, stems or leaves, systemic fungicides enter the xylem and phloem and are translocated to organs of the plant. As a result the fungicide is carried to all sites of fungal infection in the plants tissues.
