The Chemical Pest Control
A pest is usually seen as an organism potentially hazardous to health
and is in competition with humans for space food or soil. Pesticides
are any chemical or biological agent that kills plant or animal pests;
herbicides, insecticides, fungicides, rodenticides, etc. are all
pesticides.
There are various types of chemical pesticides available such as
contact pesticides which are sprayed directly onto the crop,
systematic pesticides, which are sprayed on the crop but absorbed by
the leaves and transported through the plant, and residual pesticides
which are sprayed on the soil before the crop is planted.
An ideal pesticide should:
- Be specific-toxic only to the targeted organism
- Not persist- but be unstable enough to break down into harmless
substances and;
- Not pass accumulate along the food chain
I will now, using examples, assess the advantages and disadvantages of
using chemical pest control, then come to a conclusion.
Pesticides have been used for some time, and have been used in large
amounts in most parts of the world to try and control human diseases
however it has been debated whether or not they’re seen as ‘good’.
There are a number of major pesticides used throughout the world one
of which is Mercuric Chloride or more formerly known as Calomel. It is
of a white, grey or yellow colour and although previously used in
medicine as a laxative, Calomel is no longer used in medicine because
of the toxic risks of mercury poisoning, and is also banned in the
European Union.
It is liable to liberate hydrochloric acid under certain conditions;
however, since it contain...

Ramona the pest by Beverly Cleary is a silly, exciting and fun book to read. Ramona is excited about the first day of kindergarten. But when she gets there it isn’t what she thought it would be like. Ramona is distracted about another classmate’s hair and can’t wait any longer to touch her hair. Ramona gets in trouble a few times but then gets over it. Her sister Beezus (Beatrice) thinks that she is a pest and everybody in her neighborhood thinks she’s a pest. At first when she starts kindergarten she loves her teacher but when Ramona gets in trouble a few times she’s beginning to thinks her teacher doesn’t like her anymore.
We have cumulated a profit of $206 million over this period, second of the industry. Our goal of escalating profit has advised us to increase automation level and for cutting costs, which enabled us to have the margins of all products above 30% in 2019 and an average margin of 53.4% in 2024. Additionally, we invested to keep our products updated to the market trend with an attention to customer buying criteria. Moreover, starting from recent years, we run our full capacity with second shifts whenever the market need has a possibility to accommodate our production. To achieve a greater profit, we based our pricing strategy on the market movements in general by decreasing our price by $0.50 every year except for our Low End product-Acre.
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.
What is a pesticide?A pesticide is a chemical substance used to kill pests, especially insects. A pesticide is also refered to as a biocide. Most pesticides are applied in spray form but occasionaly you will see pesticides that are in powder or pellet form. Pesticides are used on a variety of things, anything from crops like corn, barley, and wheat, to plants like petunias, marigolds, and rhodadendrons, which are usually found in small gardens greenhouses, and even in your backyard.
Spinosad insecticide is an organic compound, produced by some bacteria microbes present in the soil that were first discovered surviving in rotting sugarcane rums (Thomas, 2001). It is made of two complex compounds spinosyn A and D. The compounds are very toxic to a variety of insects and less toxic to humans and some important insects beneficial in the farm such as bees. This insecticide was first discovered by Lacey and Goodfellow, in 1975.
...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
Instead of using pesticides in farming a better alternative would be biological control. This is when a natural predator is released into the crop growing area as a result the number of pests can be reduced.

The new chemicals which are produced to kill these strong pests and weeds may be more harmful to other plants and remove nutrients within the soil, in turn reducing the yield of agricultural crops. The benefits of these characteristics are seen in Argentina according to Pelletier (2010) as they use glyphosphate resistant soybean which allowed the comeback of this crop, as the soil was severely damaged from monoculture (The cultivation of a single crop in a defined area).... ... middle of paper ... ...
Biological Pest Control is Better than Chemical Control A pesticide is any agent used to kill pests or control the incidence of insect pests, plant pathogens and weed populations. Biological control is the control of pest and weeds using specially chosen living organisms or biological products, whereas chemical control is the use of pesticides or chemicals to kill or control pests. Predators or parasites are used to keep the pest population low. Insects move, leaving their enemies behind, so by introducing their natural enemies to the environment the number of pests and their effect on the surroundings decreases. The population of the enemy can be increased by mass production in a lab.
Household chemicals were created for a reason, but that doesn’t mean they can’t be harmful to your health. For instance, pesticides used on household lawns are now proven to cause neurological disorders. These include depression, mania, learning disorders, A.D.H.D, immune system defects and memory problems. Not proven yet, but the same chemicals play a big part in leading research for the c...
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.
