The document discusses the current regulations for pesticide use in farming and whether they are sufficient for healthy living. It provides information on what pesticides are, the EPA regulations, types of pesticides and their effects, advantages and disadvantages of pesticide use, potential health effects, benefits of organic foods, and advances in technology that could reduce pesticide use. While pesticides improve food production and quality of life, the EPA approval process is slow and pesticides can damage the environment and health, especially for sensitive groups. More research into alternatives is still needed to establish effective regulations that protect both public health and agriculture.

Pest control refers to the regulation or management of a species defined as a pest, usually because it is perceived to be detrimental to a person's health, the ecology or the economy.
The principal objective of a pest control is to protect crops by maintaining the attack of the pests and diseases at an acceptable level.
There are various methods of pest control
they are basically non chemical methods and chemical methods

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

1. Pesticides
Are the current Government
regulations for pesticide use in
farming sufficient for healthy living?
Bonnie Gallea
February 17, 2012
2. What are Pesticides?
• Insecticides- Chemical substances used
to kill insects
• Herbicides- Chemical substances used
to kill weeds
• Fungicides- Chemical substances used
to kill fungus
• Rodenticides- Chemical substances
used to kill Rodents
4. EPA testing is done by toxicologists
overseen by lawyers.
A pesticide is banned
when it:
• Poses an unreasonable risk to humans or
the environment.
• Has a common active ingredient with others
that are toxic.
• Has high exposure risk- one time or multiple
times.
5. More Regulations…
• The EPA also lists how a pesticide is
to be used, how often it can be used, and
any protective clothing or equipment needed.
• The EPA re-evaluates active ingredients in pesticides
every 15 years.
• They have the power to place a pesticide on restriction
if there are questions. However, those restrictions
don’t stop the use entirely.
• The EPA requires over 100 different studies and tests
before approving a pesticide.
• Pesticides are regulated by both the States and the EPA.
6. Chemical Pesticides
• Organophosphate , Carbamate , Pyrethroid - all affect
the nervous system of insects
• Amino Acid Inhibitors, Photosynthesis
Inhibitors, Synthetic Auxin, Growth Regulators, Cell
Division Inhibitors- all categories of herbicidal
pesticides
• Mancozeb, Tricyclazole, Carbendazim, Hexaconazole,
Metalaxyl , Benomyl just some of the contact fungicides
(kills when sprayed on the surface) and systemic
fungicides (absorbed through the plant) that exist.
Over 1 billion tons of pesticides are used every year
8. • Currently 900 commercial pesticides
are approved for conventional farming.
• Toxic in large quantities.
• Accidental food contamination.
• Can damage crops trying to protect.
• Reduction of beneficial organisms.
• Changes the natural balance.
• Drifts to contaminate livestock.
• Ground water contamination.
• Resistance of crops do to overuse.
10. • Endocrine Damage-
thyroid, hormonal, reproductive, and
metabolism
• Cancers
• Nervous System Damage
• Liver Damage
• Irritation to Skin and Eyes
• Vomiting, diarrhea, slow heart rate
• Birth Defects
Most health risks are associated with farm workers or
improper use although many studies have been done
that support endocrine damage to children from
exposure to pesticides in food.
12. • Reduced deforestation-better crop yield less land
needed.
• Reduction in fertilizer used- less fossil fuels
• Pesticides enable farmers to till less (less weeds)
in turn causing less soil erosion.
• Food production has increased
20-50% over the last 40 years.
• Less water needed to produce crops.
• Disease control-from insects, fungus,
and toxic weeds.
• Protecting livestock from insects and rodents.
• Cost effective-more money for the farmers, better
prices in the grocery store.
14. • New testing is being done to determine if
foods are grown organically or
conventionally. They test
nitrogen and oxygen content.
• Independent researchers funded
by the U.S. and other governments are testing
pesticides for endocrine disruption as well as
other health risks. The EPA’s testing is
limited in scope.
• New techniques in pesticide free farming are
being tested around the world.
16. Billions of dollars are spent every year for
organic food and what are their benefits if any?
• Nutritionally, conventional and
organic foods are the same.
• 20 organic chemicals are legally
used in the production of organic
foods, the quantity of which is not recorded. Although
natural, many of these chemicals still have risks.
• Because manure is often used instead of fertilizer there is
a higher incidence of pathogens, such as E.coli.
• Organic yields are much less therefore more land would
be required.
• Consumers pay more without actually getting more.
18. • Green Pesticides- biodegradable, safe, natural
methods are being explored. Some use cow’s
urine, plant leaves, shellac, sucrose, and even
yeast to maintain and improve crops. These
would be less toxic to humans, animals, and
the environment.
• Transgenic Crops- genetic
engineering is being used to build
crops, making them disease
resistant, able to stand up to
fertilizer better, create deeper root
systems, and increase yields.
Lowering the need for pesticides.
20. Are the current Government regulations for pesticide
use in farming sufficient for healthy living?
• There is substantial evidence that pesticides
improve our quality of life, allowing many
people around the world access to an
abundance of healthy food.
• Pesticides have been proven to reduce the need
for fertilizers and to stop deforestation,
increasing production and lowering the risks to
global warming.
21. Are the current Government regulations for pesticide
use in farming sufficient for healthy living?
• Disease control is an important aspect of
pesticides also. The Black Plague and the Irish
Potato Famine are both linked to thousands of
deaths and could have been prevented with
pesticides.
However…
22. Are the current Government regulations for pesticide
use in farming sufficient for healthy living?
• The EPA’s process of placing a pesticide on
restriction for months or even years before
making a determination of it’s toxicity creates
potential health hazards.
• Pesticides can damage the environment as
much as they help, changing the natural
balance and reducing the beneficial organisms.
23. Are the current Government regulations for pesticide
use in farming sufficient for healthy living?
• Organic food is an option for some but not for
all, cost and availability are prohibitive. They
still have traces of pesticides, some of which
are legal, and their nutritional value is virtually
identical.
• The health risks associated with pesticides are
substantial especially for those who are young
or sensitive.
24. Are the current Government regulations for pesticide
use in farming sufficient for healthy living?
• Chemists and geneticists are working to
improve our pesticides as well as our crops
grown. Much more research and development
needs to be done in this area.
Finally…
• The government regulations designed to keep
us safe work far too slowly. We need to
continue to push for better options.
