Any substance that is used in order to kill, drive away, or control a pest is labeled as a pesticide. Pesticides are released everywhere within our environment for better or for worse. There are many chemicals involved in the makeup of pesticides. One short list of these chemicals include: Aldrin, Atrazine, Chlordane, Chlordecone, DDT, DDE, DDD, Endosulfan, Endrin, Heptachlor, Hexachlorobenzene, Methoxychlor, Methylene Chloride, and Toxaphen. Pesticides are used most noticeably in fields, homes, schools, roads, and forests. These toxins can and do linger in our soil, our water, and our air leaving them polluted and harmed. Pesticides are one of the few toxic and poisonous substances allowed to be released into our environment with the sole purpose of harming and killing livings organisms. These pesticides can be broken down into four general classifications; herbicides, fungicides, rodenticides, and insecticides. Herbicides are used against unwanted plants by farmers and pretty much anyone who own a lawn or garden. An example of these unwanted plants would be weeds, which are common everywhere including yards and gardens. Fungicides are used to control plant diseases that could infect and harm crops. They can also be used on wood to prevent it from attracting wood rot. This practice is common amongst construction workers building homes and other structures. Rodenticides are used to control rodents that have the ability to ruin stored food and carry harmful if not deadly diseases. The most common example of this is when a building is sprayed against rats and other rodents. Insecticides are used both on and off of farms to fight insects that cause damage to crops. They can also be used to kill mosquitoes and other germ carrying in...

...down a slope to another location. Spray drift, however; happens when pesticides being sprayed gets caught in the wing and carried off target. Leaching is when soil that contains traces of pesticide moves through a larger body of water. Last but not least volatilization takes place when a liquid form of pesticides changes phase of matter into a vapor state and is carried through the air to places it should not be. This process is very similar to the process water in a puddle goes through when t is evaporated. The third way pesticides are moved is degradation. This is also known as the breakdown of the chemicals that makeup pesticides. Just like when pesticides are transferred there are multiple ways that pesticides can broken-down. They can breakdown microbialy, which takes place by microorganisms like bacteria breaking down the pesticide. They can also be broken-down
The Everglades used to be a very beautiful tourist attraction, but have been largely affected by the existence of pesticides. However, the majority of pesticides is not specifically targeting the pest only but they also affect non-target plants and animals during their application. The Effect of pesticide runoffs on the Everglades is destroying one Florida’s major tourist attractions due to the cultivation of sugar cane just to mention one of those responsible and creates a loss of natural habitat, water pollution, and threatens existence of wildlife. Many pesticides are not easily degradable; they persist in soil, leach to groundwater and surface water and contaminate wide environment.
There are many issues regarding the raising and producing of various livestock animals, and the use of pesticides on various types of crops. The movie Food.Inc does a good job explaining these issues, but in a very biased way. It makes agriculturists look like terrible people, when this is not the case.
When pesticdes are sprayed on crops, where do the pesticides go after they are applied to the crops? They soak into the ground where the roots can pick up the pesticide.That further proves my point that pesticides soak into the ground.
The spinosad insecticide is very active and effective in controlling insects and pests. It acts on both contact and ingestion by an insect. The insecticide is subjective to the stages of life of an insect such as larvae or adult stages and the insect species. The insecticide mode of action is through the neural mechanism. It affects the neural transmissions and processes of an insect. Spinosad is applied to field crops during the entire growth process as specified. It is applied to crops such as flowers, vegetables, fruit trees and also cereals. Some flower farmers spray their crops before harvest to rid them off harmful insects (Kole, 1995). Farmers use spinosad insecticide to kill harmful insects that destroy their crops and spread diseases lowering the yield. It is also used to control storage pests that destroy cereals stored in bins. Quality food produce is another reason for the applying the insecticide.
Have you ever thought about how your fruits and vegetables are grown? How about which ingredients are put into bug sprays and insecticides to ward off those pesky insects? Look no further because author Rachel Carson looks deep into the many environmental issues caused by pesticides and herbicides in her New York Times best-selling novel, “Silent Spring.” “Silent Spring” is a collection of studies which were performed in an effort to educate others about the harmful things occurring everyday to their foods and every-day environment in hopes of giving them a wake up call. This novel is thought by many to be a revolutionary novel that forced people to take notice of the harm being caused in their world, many of which people were unaware of. After discovering the results of these chemicals, it really makes one wonder, is the luxury of being insect free really worth all of the consequences?
The book starts with a foreword that highlights the motivation for having written the book. The book has a table of contents organized into seventeen chapters that highlight the different effect of the use of pesticides to the ecological system within the earth surface. The book is chronologically organized into chapters that flow and express a single idea for the writer. This organization has given the book much readability regarding the flow in its content and format to a
A question commonly associated with the word insecticides is, what are they? Well I have the answer, insecticides are chemicals that are used to eliminate insects. In the agricultural industry, insecticides are classified into different categories,and the most used is carcinogenic. A carcinogenic insecticide is a substance or agent producing or causing cancer. This is just one of the reason that I believe there are more cons then pros when dealing with a insecticide.. When I was a kid , I can remember my parents taking me and my brother an apple orchard and picking apples. I couldn't wait to eat them until I got home, but we couldn't eat an apple because of what insecticides could be on the apple
The use of chemicals in weapons dates back thousands of years, from poison arrows to poisonous fumes. However chemical warfare took a new approach during World War I. The first large scale attack was chlorine in april 1915. World War II brought on a entire new spectrum of chemical weapons and many countries obtained large stockpiles.1There are four different categories in which chemical weapons are organized based on what the effects are. The first category is blister agents which cause blistering of the skin. The second category is choking agents which cause the airway passages in the victim's throat to close resulting in death. The third category is nerve agents which causes damages to the victims nerves. The most recent uses of chemical weapons was on august 21, 2013 in Damascus ,Syria which resulted in numerous casualties.2
...ortation of plants, fruits, vegetables, and animals. Indiscriminate pesticide use kills the good with the bad. Long term and wide spread pesticide use poisons underground water sources, which, in turn, poison plants, animals, and humans. And, finally, by our uninformed actions, new super races of pests continue to evolve and create even greater dangers than the original.

As time has progressed, there has always been an overarching need for high amounts of crop production throughout the world. With the rapid rate of population growth, the need for crops and other sources of nutrients is only increasing. In order to meet these high demands and increase yields, farmers and other agriculturalists have started implementing the use of pesticides. These chemical mixtures are being used in order to prevent, destroy, repel or mitigate any pests from destroying growing crops. However, using pesticides on crops can create massive amounts of pollution, negatively affect an individual’s health, and can spark biodiversity loss within an ecosystem. According to Michael C.R. Alavanja, “Over 1 billion pounds of pesticides are used within the United States (US) each year and approximately 5.6 billion pounds are used worldwide”. With all this in mind, it is clear that pesticides should not be made available to farmers and agriculturalists, and should
Pesticide is a chemical used to prevent, wipe out and control the pest problem in agriculture. The use of pesticides have become a common practice around the world, and used almost everywhere, such as agricultural fields, homes, park and school, and so on. Most pesticides are insecticides, herbicides and fungicides that have distinct purposes. Insecticides are used to control insects; herbicides are used to destroy plants; fungicides are used to prevent molds and mildews. Most commonly pesticides contain highly toxic chemical such as Acid copper chromate (ACC), Acephate and Chlorpyrifos, and so on. One of example of insecticides, Chlorpyrifos, sprays widely on a variety of food and golf courses in order to control pests in a cornfield. However, “Chlorpyrifos can cause cholinesterase inhibition in humans; that is, it can over stimulate the nervous system causing nausea, dizziness, confusion, and at very high exposures (e.g., accidents or major spills), respiratory paralysis and death.” (EPA GOV) In the market has thousands of products are similar as Chlorpyrifos.

Organic farming has mushroomed drastically in importance and influence worldwide from its modest beginnings in the first half of the last century. Organic farming is production of food and livestock without the use of herbicides, pesticides, weedicides, fertilizers or genetically modified organism and use natural resources such as manure and compost instead. In other words, it is a production system which maintains the quality of soil ecosystem as well as human beings. According to IOWA State University, “the chemicals were not used for farming before World War 2. A number of munitions used in farming have contributed to field of agriculture. For instance, ammonium nitrate used as ammonium nitrate fertilizer”.
