Pesticides, as defined in the Agricultural and Veterinary Chemicals Code Act 1994 (Cwlth), is an 'agricultural chemical product?. More clearly, as www.epa.nsw.gov.au states, it is 'a substance or mixture of substances that is represented, imported, manufactured, supplied or used as a means of directly or indirectly?. Crop protection products manage pest organisms by biologically, chemically or physically affecting their metabolism and a way of they live. The term pesticide includes all of the following: herbicide, insecticide, insect growth regulator, nematicide, termiticide, molluscicide and so on.

Even though many far-reaching consequences have been reported by mass media and scholars so far, pest controllers are still being used as the main source of protection against pests. First of all, there is no denying fact that this type of method will make sure that there is a marked increase in the food production, as it helps the farmers over the world prevent their crops from being damaged by serious pets, and harvest as many tons as possible, resulting in more food supply and feeding the overwhelming majority of world population who are dying from world hunger. According to a recent research conducted by Namangan Agriculture Institute, 45 percent of total agricultural products harvested in the southern part of Namangan in 2016 resulted from pest controllers. As financial perspective, it is commonly viewed that those, who plant and harvest crops but also be harmed by pests, make a considerable profit, whereby they use pest controllers to kill and reduce the causes that pets make. What is being meant that the less oppression they face, crop-field owners, the more money they make, which in turn, the local well-being of the community in places where the world poverty is being experienced will be improved for sure. Last but not least, an underlying reason behind pesticide uses is that this practice is a guarantee of prevention of serious diseases. More specifically, not only some certain insects such as chewing and sucking pests can cause raising infection, but also they can create illnesses. Such diseases can cause plants to face extreme deterioration, as well as poison consumers. By the way of this practice, we can lessen the side-effect.

On the other hand, many critics point out that many drawbacks cannot be overlooked. First and foremost, it was thought that pesticides in natural environment would be in such a small quantity that there would be no risk to the environment and human beings? health, but it was/is ironical and it is an ill-hidden fact that some of the researches on food safety are carried out and funded by the pest controlling industries, putting all in the risk of faking data on pest researches and the idea concerning increased food production and improvements in the resilience of crops and plans is harming our environment. So, environmental risk can be minimized when a number of such risk factors such as persistence, mobility, none-target toxicity, the volume of use are close to zero level.

Degradation- is the time when pesticides eventually break down in the environment and how far it happens is dependent on the pesticides and environment. For even decades, DDT could remain in the soil with no breaking down, which this circumstance is considered that the farmland, where pest controllers are used, might be contaminated considerably. A scholar in Khiva claims he has information presenting that soil contaminated by chlorine resulted from pesticides is thirty times the permissible level. Before the 1970s when DDT was forbidden as a general agricultural insecticide in the Soviet Union and the United States, 78 aerodromes exploited by crop spraying airplanes in Khorezm and Karakalpakstan in the north-west of Uzbekistan were used to spray chlorine and other chemicals which still demonstrates health risks for the local field owners. 

Bio-accumulation- pesticides can accumulate or build up in body tissues or body fat of men or animals. This is called bio-accumulation, and if the body does not have a way of getting away pesticides, every time your body is exposed to pesticides more store in fat cells. The tiny amount of this type of the controllers in the soil and water can magnify into a significant hazard to predators at the top food chain. Besides, once pesticides have been evaporated, they can reach to water, where fish we usually feed on can be poisoned or it may reach to groundwater, where many farmland owners use for domestic use. 

In conclusion, I do believe that there are more negatives than things done so far for benefits. This is mainly because the way we live in and treat to nature has changed dramatically, leading to the extension of some living organisms. Instead of this, it had better use alternatives, especially natural predators against pests: nematodes and other useful insects. By the way of doing this, we can save expenditure on pesticides, and as well as the living environment.
