PESTICIDES: BOON OR CURSE

An increase in population demands, an increase in food supply and with it increases the need for production of food sources. So as to stabilize the food supply rate, ways are found out to increase the cultivation of different crops. The use of pesticides too hikes when an increase in production of food is demanded.

The term pesticide covers a wide range of compounds including insecticides, fungicides, herbicides, rodenticides, molluscicides, nematicides, plant growth regulators and others.

Pesticides are used worldwide to manage agricultural pests. They kill and repel unwanted pests, but also cause harms to the environment in different ways.

The production of pesticides started in India in 1952 with the establishment of a plant for the production of BHC near Calcutta, and India is now the second largest manufacturer of pesticides in Asia after China and ranks twelfth globally.

If the credits of pesticides include enhanced economic potential in terms of increased production of food and fibre, and amelioration of vector-borne diseases, then their debits have resulted in serious health implications to man and his environment. There is now overwhelming evidence that some of these chemicals do pose a potential risk to humans and other life forms and unwanted side effects to the environment.

According to The Stockholm Convention on Persistent Organic Pollutants, 9 of the 12 most dangerous and persistent chemicals are pesticides. Highly hazardous pesticides may have acute and/or chronic toxic effects and pose a particular risk.

The high-risk groups exposed to pesticides include production workers, formulators, sprayers, mixers, loaders and agricultural farm workers. During manufacture and formulation, the possibility of hazards may be higher because the processes involved are not risk-free. In industrial settings, workers are at increased risk since they handle various toxic chemicals including pesticides, raw materials, toxic solvents and inert carriers.

The symptoms of pesticide poisoning can range from a mild skin irritation to coma or even death. Acute health problems may occur in workers that handle pesticides, such as abdominal pain, dizziness, headaches, nausea, vomiting, as well as skin and eye problems. In China, an estimated half million people are poisoned by pesticides each year, 500 of whom die. Pyrethrins, insecticides commonly used in common bug killers, can cause a potentially deadly condition if breathed in.

Another major problem associated with pesticide use is bioaccumulation and biological magnification. Bioaccumulation is when a substance builds up in the body because the body does not have the proper mechanisms to remove it. Many synthetic pesticides are not able to be broken down. Once they enter the body of an organism, they are permanently stored in the body tissue. The pesticides that accumulate in an organism’s body can cause harm to the organism or can be passed on to a predator.

Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants.

In India, the first report of poisoning due to pesticides was from Kerala in 1958, where over 100 people died after consuming wheat flour contaminated with parathion (Karunakaran, 1958).

According to WHO data, in 2012 an estimated 193,460 people died worldwide from unintentional poisoning. Of these deaths, 84% occurred in low- and middle-income countries. In the same year, unintentional poisoning caused the loss of over 10.7 million years of healthy life (disability adjusted life years, DALYs).

Nearly a million people die each year as a result of suicide, and chemicals account for a significant number of these deaths. For example, it is estimated that deliberate ingestion of pesticides causes 370,000 deaths each year. The number of these deaths can be reduced by limiting the availability of, and access to, highly toxic pesticides.

Pesticides can contaminate soil, water, turf, and other vegetation. In addition to killing insects or weeds, pesticides can be toxic to a host of other organisms including birds, fish, beneficial insects, and non-target plants. Insecticides are generally the most acutely toxic class of pesticides, but herbicides can also pose risks to non-target organisms.

10 samples of pesticides, insecticides fail quality check

Wed, 09 Aug 2017

BATHINDA: The Punjab agriculture department has issued notices to six companies manufacturing pesticides and insecticides after some samples failed the quality check. “Bains said the agriculture department was serious about the quality of pesticides and insecticides as the low quality products could cause loss to the cotton crop and hurt farmers’ interests. As many as 22 samples were collected from Fazilka, 27 from Bathinda and 51 samples were collected from Mansa and Muktsar. As per the Bureau of Indian Standards (BIS), samples have tolerance limit up to 10% to clear the quality check in the first category, 5% in the second category and 3-5% in the third category. Seven samples from Fazilka and three from Bathinda failed the inspection.

Eggs contaminated with ‘potentially harmful’ pesticide being sold in UK

Eggs contaminated with the ‘potentially harmful’ pesticide fipronil have been distributed in the UK, after warnings from the EU sparked panic across the continent.

Aldi and Lidl stores in Germany have already taken millions of eggs off shelves amid fears they have tainted with traces of the pesticide Fipronil.

EU bodies immediately notified food safety authorities in Britain, France, Sweden, and Switzerland after it emerged that eggs contaminated with the insecticide may have entered their territories.

Supermarket giant Aldi said it was a ‘purely precautionary’ measure and added that eggs sold in its UK stores were produced in Britain.

The Food Standards Agency has reassured buyers that the actual number of eggs sprayed with the insecticide in the UK is ‘very small’.

And the risk to public health is reportedly ‘very low’, the FSA added, although the World Health Organisation warns that the pesticide is moderately toxic.

The WHO considers fipronil to be moderately toxic, and says very large quantities can cause organ damage.

Belgian and Dutch authorities are now investigating how the insecticide came into illegal contact with egg-laying chickens.

Bed Bugs – The Bloodsucking Parasites

Bed bugs are the nocturnal, reddish-brown insects. They are the pesky little pests of the size between 1 and 7 millimeters. These wingless creatures have dorsoventrally flattened bodies that allow them to hide in areas such as floor cracks, carpets, beds and upholstered furniture.

Bed bugs feed on the blood of humans and other warm-blooded animals as their only source of nutrition. In order to mature into adults, they must feed once during each of their immature stages. Adult females also need blood in order to produce eggs.

Bed bugs inject an anticoagulant along with saliva when they pierce skin for the meal. The anticoagulants are responsible to generate response in person’s body. The size of the bite depends upon the anticoagulants and the number of times a person is bitten.

Bed bug bite reactions don’t always appear immediately after you’re bitten and may take a few days to begin causing symptoms. However, not everyone reacts to bed bug bites in the same manner. Bite reactions are variable with the intensity increasing or decreasing depending upon the number of bites.

Bites are commonly found on the parts of the body that are more likely to be exposed to bed bugs during sleep – the hands, neck, face, shoulders, legs and arms. Bed bug bites are often grouped together in a small area and at times may occur in a line or a zigzag pattern. Bites normally look like small, flat or raised areas that may become inflamed, itchy, red or blistered.

Scratching bed bug bites and failure to keep the bites clean and disinfected may lead to a secondary infection that can cause further swelling and bleeding. Children, the elderly, and individuals with weak immune systems, particularly those who are bedridden, may develop secondary infections that result from bed bug bites.

The bites can be so harmful leading to infection and even death. Following are some recent evidences which prove that the tiny creatures are the great threat for society.

Jersey City woman found dead in home overrun with bedbugs
By Adam Hochron July 31, 2017 6:08 PM
First-responders tried unsuccessfully to resuscitate a woman police were told was found unresponsive in her home on Sunday morning.

When medics arrived at the home they needed to call in a hazmat team to deal with a massive bug infestation problem. In addition to the woman, five other people, including the woman’s parents and her daughters, lived at the home at the time she was found. She was declared dead at the scene.

The home was infested with bedbugs, and the infestation was so bad that a hazmat station was set up on Griffith Street to disinfect anyone who had gone inside the building. The Fios story also reported that the health department was called in to check on the home’s safety and to take whatever action against the homeowners was necessary

Parliament is infested with bedbugs and there’s ‘urgent action’ to clear them out

By Keiron Mccabe, 12:20, 21 JUL 2017

Pest-busters are taking urgent action to wipe out a bedbug infestation in Parliament. The blood-sucking parasitic insects were discovered this week in the Palace of Westminster and 7 Millbank, both home to MPs’ offices.

It is the latest in a series of pest related problems to beset Parliament, which spent £103,157 combating mice, flies, months, pigeons and gulls in the last year alone. Staff and MPs have been told to consult the NHS if they think they’ve been bitten.

Monitoring is underway to check if the bugs – which are notoriously difficult to remove – have spread to other areas.

Woman claims arm infection, blood disease came from a bedbug bite

By Megan Schuller, July 2, 2017

Johnson, 58, was bitten about a month ago and was hospitalized for several days, fighting the infection. Her left hand swelled to more than twice its normal size, and she complained of pain and tenderness in her arm.

Johnson recently returned to the hospital because of stiffness in her arm that alarmed her. She plans to see a blood doctor. She said she spends about $80 dollars a month on preventive measures to help keep the bedbugs at bay.

“I had to leave (the housing authority’s John C. Murphy building) because it was so bad. I was there for two years. It was bad there and here, People walk around all eaten up,” Johnson said. “People aren’t going to do anything about it. People are too scared to talk.” Johnson plans to eventually move out of the JFK building.

By going through the above evidences we come to know that there is an urgent need for actions to be taken against these blood sucking parasites. There are the conventional methods mostly used against the pest viz. fumigation, spraying methods, heat treatment, fungal treatment, vacuuming, etc. which are proved to be temporary, hazardous and ineffective solution.

We at CTech Corporation provide an alternative solution for the conventional methods against these pesky little pests. These products are based on green technology which gives effective solution. Our product TermirepelTM is an extremely low concern extremely low toxicity, non-carcinogenic and non-mutagenic compounds and non-hazardous insect/termite aversive. It combines the best of chemistry and green practices to give an environmentally safe product which keeps away effectively while at the same time guaranteeing safety to the environment, plants, animals and fragile ecosystems.

Our product is available in three forms viz. Masterbatch, Liquid Concentrate and Lacquer. The masterbatch of Termirepel™ can be incorporated in wires and cables which are used in domestic wiring. The liquid concentrate is mixed with paints in specific ratio while lacquer can be directly applied on the surfaces like wood, metal, concentrate, etc.

Our product is prepared by using the sense mechanism of insects. Our product creates fear in the insects mind by mimicking the feel of danger. It has some peculiar smell which makes the insect stay away from the application. The fear is passed on to the progeny. Thus the motive gets completed to get rid from the insects.
