Used in yards, farms and parks throughout the world, Roundup has long been a top-selling weed killer. But now researchers have found that one of Roundup’s inert ingredients can kill human cells, particularly embryonic, placental and umbilical cord cells.

The new findings intensify a debate about so-called “inerts” — the solvents, preservatives, surfactants and other substances that manufacturers add to pesticides. Nearly 4,000 inert ingredients are approved for use by the U.S. Environmental Protection Agency.

Glyphosate, Roundup’s active ingredient, is the most widely used herbicide in the United States.  About 100 million pounds are applied to U.S. farms and lawns every year, according to the EPA.

Until now, most health studies have focused on the safety of glyphosate, rather than the mixture of ingredients found in Roundup. But in the new study, scientists found that Roundup’s inert ingredients amplified the toxic effect on human cells—even at concentrations much more diluted than those used on farms and lawns.

One specific inert ingredient, polyethoxylated tallowamine, or POEA, was more deadly to human embryonic, placental and umbilical cord cells than the herbicide itself – a finding the researchers call “astonishing.”

“This clearly confirms that the [inert ingredients] in Roundup formulations are not inert,” wrote the study authors from France’s University of Caen. “Moreover, the proprietary mixtures available on the market could cause cell damage and even death [at the] residual levels” found on Roundup-treated crops, such as soybeans, alfalfa and corn, or lawns and gardens.

Nitrate levels in organic lettuce are a fraction of levels found in conventional hothouse lettuces. Experts, however, say authorities are reluctant to showcase the benefits of organic farming.

Ari Kulmanen, an organic farmer from the town of Ikaalinen in western Finland, studied nitrate levels in lettuce because no official studies on lettuce nitrate content exist. His research showed sharp differences in the nitrate levels of organic and conventional lettuce.

”The nitrate levels for organic lettuce were 150 mg/kg. Conventional lettuce carried levels of over 3,500 mg/kg,” says Kulmanen.

In Finland conventionally grown produce is often presented as “near organic,” according to Jouni Kujala, a research director at Helsinki University’s Ruralia Institute.

“It seems as if Finnish authorities have not wanted to make conventional and organic segments compete for consumer choice,” says Kujala.

Agricultural Aromatherapy: Lavender Oil As Natural Herbicide

Could essential oils extracted from lavender be used as a natural herbicide to prevent weed growth among crops? Research carried out in Italy and reported in the current issue of the International Journal of Environment and Health suggests the answer may be yes.

Elena Sturchio of the National Institute of Health and Safety at Work in Rome and colleagues there and at the Department of Infectious and Tropical Diseases, and the Department Crop Production, at Tuscia University, in Viterbo, have investigated the inhibitory effects on weed growth of aromatic oils, or mixtures of phytochemicals, from plants such as lavender, Lavandula officinalis.

EU taps emerging talent for new organic logo

The European Commission has re-started the search for a new logo to appear on pre-packaged organic food, over a year after original designs were scrapped due to similarly to a supermarket’s logo. The 2007 EU regulation on organic foods (834/2007) provided for a new, common organic logo to appear on pre-packaged organic food sold in the EU, on a mandatory basis if it originates from the EU and on a voluntary basis if from outside. It was originally planned that the logo would start appearing on products this year. However the common logo that was drawn up was withdrawn in April 2008, after it was pointed out that it resembled the logo of Aldi supermarket. Moreover, it used the word ‘Bio’ – a term that is not associated with organics in the English language. The Read More…

Pesticides, fresh produce washing is not enough

Organic eating is proving to be more than a fashion. According to a recent U.S. report published by the Environmental Working Group (www.ewg.org) – a non-profit environmental-research organization – washing and rinsing fresh produce may reduce levels of some pesticides but are not sufficient to eliminate them. “There is growing consensus in the scientific community that small doses of pesticides and other chemicals can adversely affect people, especially during vulnerable periods of fetal development and childhood when exposures can have long-lasting effects”, the EWG report highlights.

Organically grown fruits and vegetables are not covered with synthetic fertilizers, anti-fungal treatments or radiation – and they’re not genetically modified. “Peeling also reduces exposures but valuable nutrients often go down the drain with the peel. The best option is to eat a varied diet, wash all produce and choose organic when possible to reduce exposure to potentially harmful chemicals”. Organic meat, eggs and dairy products come from more humanely raised animals that haven’t been pumped full of antibiotics or growth hormones. Another reason to support organic agriculture is that organic farms are generally smaller-scale and conservation-conscious, which means that they strive to reduce the impact of their practices on natural resources. Furthermore, many seem to maintain that organic food also tastes better. The Environmental Working Group suggests that switching to organic could start with just a few foods that are most often eaten. Here are the recommended seven foods to start with: Dairy products: Milk, yogurt and cheese are considered healthy bone-strengtheners, especially for children, but the additions of hormones and antibiotics undermine the simple goodness of commercial dairy products. Potatoes: Commercially farmed potatoes are among the most pesticide-filled vegetables, and they still contain residues after being washed and peeled. Meat (including poultry and eggs): Animal products can contain antibiotics, hormones and even heavy metals like arsenic that is used to prompt an animal’s rapid growth. Ketchup: Even besides the pesticide issue, research has shown organic ketchup has nearly double the good-for-you antioxidants of conventional ketchup. Apples: Apples are among the most pesticide-filled fruits out there. Coffee: Conventional coffee farming relies heavily on pesticide use and contributes to deforestation around the globe. Nuts and seeds (including peanuts and nut butters): Pesticides and fungicides are rampant in the production of these foods, and many varieties are bleached after harvest. The Environmental Working Group has developed the “Shopper’s Guide to Pesticides in Produce”, now in its fifth edition, which ranks 43 fruits and veggies according to their pesticide content. The Association suggests that it is better to choose the organic grown varieties of peaches, nectarines, cherries, strawberries, table grapes, apples, pears, peppers, lettuce, carrots – which register the highest level of pesticides when conventionally grown. On the contrary, onions, avocados, corn, pineapples, mangos, asparagus, peas, kiwifruits, cabbages, aubergines, papayas, watermelons, broccoli and tomatoes don’t contain in general worrisome levels of pesticides.

Which is a better strategy, specializing in one crop or diversified cropping? Is conventional cropping more profitable than organic farming? Is it less risky?

To answer these questions, the University of Wisconsin’s College of Agriculture and Life Sciences and Michael Fields Agricultural Institute agronomists established the Wisconsin Integrated Cropping Systems Trial (WICST) in 1990. This research is funded by USDA-ARS.

Systems ranging from species-diverse pasture and organic systems to more specialized conventional alfalfa-based forage and corn-based grain systems were compared at two sites in southern Wisconsin from 1993 to 2006.

Crop production analysis was published in the 2008 March–April issue of Agronomy Journal while this companion article focuses on the net returns and associated risk exposure of these systems. Full research results from this current study are presented by Chavas et al. in the 2009 March–April issue of Agronomy Journal.

“In our study we found that diversified systems were more profitable than monocropping,” explains Joshua Posner, University of Wisconsin.

Spreading Antibiotics In The Soil Affects Microbial Ecosystems

Antibiotics used extensively in intensive livestock production may be having an adverse effect on agricultural soil

In a presentation to the Society for General Microbiology meeting at Harrogate International Centre March 30, Dr Heike Schmitt from the University of Utrecht, the Netherlands described how antibiotics passed from the animals in manure that was then spread on farmland. Although higher organisms, such as earthworms, would only be affected at unrealistic concentrations of antibiotics, changes in soil bacterial communities have been found repeatedly using molecular microbiological techniques.

Bacteria involved in the nitrogen cycle, which replenishes nutrients in the soil, seem to be particularly affected. The effects persisted over several weeks and were still seen even when the antibiotics had broken down significantly. In addition the microbial population of the soil changed as fungi replaced the bacteria suppressed by the antibiotics.

West Bengal to go organic; plans to set up bio-villages

The West Bengal government, which is keen to spread organic cultivation, has resolved to set up one bio-village in each of the 341 blocks in the state in the next two years. The objective behind setting up bio-villages is to create role models for adaptation to organic farming. Already 75 bio-villages have been set up across the state up to 2007-08 since its launch in 2004-05. There was plan to set up another 64 biovillages in 2008-09. In these villages, work is in progress to train farmers on the proper use of bio/botanical pesticides and use of microbes and parasites to wage a biological warfare against prevalent pests and plant diseases. “Those villages, which have been selected as bio-villages are blessed with rain-fed irrigation and have achieved a 200% or more cropping intensity. Post-selection, the prime task is to make farmers aware about the adoption of bio-farming through a series of workshops, training and demonstration programmes,” said agriculture secretary Sanjeev Chopra. The agriculture department has decided to carry out the programme on a shoe-string budget. For this, it has submitted a proposal to the finance department, asking for just Rs 1 crore for each year, from 2009-10 to 2011-12. The money has been sought to provide training to farmers and supplying bio-inputs to them at subsidised rates or free of cost. As cultivation with organic inputs cannot be initiated overnight in areas that are already inflicted with chemical fertilisers and pesticides, the process starts with the implementation of cultivation with bio-inputs. Here, the thrust is on using Read More…

Herbicide drift, which occurs when pesticides “drift” from the targeted application area to a nearby non-targeted area, is a particular concern in Midwestern regions of the United States. In the Midwest, where the topography is relatively flat and large-scale farms and agriculture production facilities reside side-by-side with housing developments and woodlands, herbicide drift can have an impact on wildlife, livestock, timber production, and quality of life for human neighbors.


A study published in a recent issue of HortScience evaluated the effects of field corn herbicides on white oak seedlings. White oak, a popular landscape and forest species native to the eastern United States, has been suffering from an abnormality called “leaf tatters”, which give the leaves a lacy appearance. Leaf tatters in white oak trees have been reported in states from Minnesota, south to Missouri, and east to Pennsylvania. This problem is not just aesthetic; it can affect a substantial portion of a tree’s canopy, reducing the health of the tree. Leaf tatters make affected trees more susceptible to other stressors such as adverse environments, air pollution, and pests, and can make containerized oak seedlings unmarketable.

New Test For Detecting Fake Organic Milk

Scientists in Germany are reporting development of a new, more effective method to determine whether milk marketed as “organic” is genuine or just ordinary milk mislabeled to hoodwink consumers.
In the study, Joachim Molkentin and colleagues point out that organic milk has soared in popularity in many countries. Sales in Germany, for instance, rose by almost one-third between 2006 and 2007. Consequently, crooks may take advantage of the situation by marketing increasing quantities of fake organic milk. That situation created a need for better tests to detect the fraud.

To address the issue, the scientists developed a test based on an analysis of milk fat for the ratio of stable isotopes of carbon. They used it to identify milk samples from cows raised on feed containing a higher ration of maize. Such a feeding regimen is typical of conventional milk production.

More organic food production could help Africa: UN

Demand for organic foods will keep growing despite the world economic crisis, creating an opportunity for farmers in poor countries, the United Nations’ trade and development agency said on Monday.

In a research note, UNCTAD projected that sales of certified organic products would reach $67 billion in 2012, up from $46 billion in 2007 and about $23 billion in 2002.

“Even in this current economic crisis, where demand for most products is dropping fast, demand for organic products continues to grow,” it said.

Organic Weed Control: Scientists Serve Up Mustard Meal To Tame Weeds

Sinalbin, the same compound that gives white mustard its pungent flavor, could also prove useful in fighting weeds. Agricultural Research Service (ARS) studies suggest sinalbin and other compounds released into soil by applications of white mustard seed meals can kill or suppress certain weedy grasses and annual broadleaf weeds.

Agronomist Rick Boydston, with the ARS Vegetable and Forage Crops Research Unit in Prosser, Wash., is conducting the studies with plant physiologist Steven Vaughn, at the ARS National Center for Agricultural Utilization Research in Peoria, Ill. They evaluated the effects of three mustard seed application rates: half a ton, one ton and two tons per acre. Of the three, the one-ton and two-ton rates worked best in peppermint, reducing barnyard grass, green foxtail, common lambsquarters, henbit and redroot pigweed populations by 90 percent several weeks after application.

Human Hair Combined With Compost Is Good Fertilizer For Plants

Agricultural crop production relies on composted waste materials and byproducts, such as animal manure, municipal solid waste composts, and sewage sludge, as a necessary nutrient source. Studies have shown that human hair, a readily available waste generated from barbershops and hair salons, combined with additional compost, is an additional nutrient source for crops.

Although human hair has become commercially available to crop producers in the past couple years, it has not been proven to be an exclusive source of nutrients in greenhouse container production.

Vlatcho D. Zheljazkov, Juan L. Silva, Mandar Patel, Jelena Stojanovic, Youkai. Lu, Taejo Kim, and Thomas Horgan of Mississippi State University recently published a research study in HortTechnology designed to determine whether commercially available noncomposted hair waste cubes would support plant growth in horticulture crops as a sole source of nutrients.

The study compared the productivity of four crops: lettuce, wormwood, yellow poppy, and feverfew, grown in commercial growth medium using untreated control, noncomposted hair cubes at differing weights, a controlled-release fertilizer and a water-soluble fertilizer. Results showed that, with the addition of hair waste cubes, yields increased relative to the untreated control but were lower than yields in the inorganic treatments, suggesting that hair waste should not be used as a single source for fast-growing plants such as lettuce.

Let us bend the rules, say organic farmers

Organic farmers have asked the Government for permission to take a “holiday” from strict organic standards in an attempt to survive the recession.

The drastic move by organisations including the Soil Association follows a dip in sales of organic produce and fears for the future of Britain’s 5,000 organic farmers.

Sales of organic food slumped 10 per cent in the 12 weeks up to the end of November, according to the latest figures from the consumer researchers TNS. Overall food sales over the same period were up 6 per cent.

Organic certification bodies, including the Soil Association, the country’s biggest campaigner for organic food and farming, asked Hilary Benn, the Rural Affairs Secretary, last week for approval to relax the rules for an indefinite period. They want their members to be able to use conventional animal feed instead of organic food concentrate, which costs double. Average organic feed prices are £320 a tonne compared with £160 a tonne for conventional feed.

The plan, which is also supported by Organic Farmers & Growers and the Organic Food Federation, would still oblige farmers to follow other organic tenets such as low stocking densities, minimum use of antibiotic treatments on animals and no use of fertilisers. But they would give up the right to label their food “organic”. The aim is to give farmers some leeway during the harsh economic climate.

GMO Contamination in Mexico’s Cradle of Corn

Raise the alarm for Mexican corn’s biosecurity: a molecular study conducted by Mexican, American and Dutch researchers demonstrates the presence of genes from genetically modified organisms (GMO) among the varieties of traditional corn cultivated in the remote regions of Oaxaca State in the southern part of the country, even though the Mexican government has always maintained a moratorium on the use of transgenic seed.

The results of this study incite the experts to demand much more restrictive protective measures. “Old time” agriculture as practiced in Mexico – where wind-blown pollination of corn is the norm and where peasants are in the habit of exchanging their seed – seems to aggravate the risk of rapid GMO contamination.

An article that details their conclusions should be published in the next edition of the review, “Molecular Ecology.” It was written by Elena Alvarez-Buylla of the Institute for Ecology of the Autonomous National University of Mexico (UNAM), with the collaboration of a dozen other scientists.

Their work could relaunch the controversy that was unleashed in 2001 by a highly controversial article in the magazine, “Nature,” the authors of which, biologists David Quist and Ignacio Chapela from the University of California at Berkeley, revealed that criollos (traditional) corn from the Oaxaca region – one of the cradles of that cereal – were contaminated by Roundup Ready (RR) and Bt genes, property of the American company Monsanto.

GM Restrictions: A Boon to the European Livestock Sector?

Several feed organisations in the EU have warned of the dangers posed by a lack of soya supplies, writes Rachel Ralte reporting for ThePoultrySite.

A report prepared for a consortium of trade associations including FEFAC, COCERAL and UECBV by Cardy-Brown & Co Ltd. entitled Impacts of EU Unauthorised GM’s on the feed & livestock sectors focuses primarily on one of the most critical issues facing today’s European livestock and feed sectors – the consequences of a loss of soybeans and soybean meal (SBM) due to the release of the much anticipated herbicide-tolerant genetically modified (GM) seed technology marketed under the brand name, RoundUp Ready 2 Yield (RR2Y).

It is a well-known fact that the new technology bears significance to all sectors, including dairy, egg production and aquaculture. However, the gravity of the situation can be best illustrated by taking into account the pig and poultry industries.

The EU is the largest importer of soybean meal. However, when China stepped into the limelight as the world’s most significant importer of whole beans and soybean oil, Europe’s market leverage has dwindled to a certain degree. Read More…

The growing markets for organic products in the US and Europe hold good prospects for Indian farmers and exporters.
The global organic market reached a size of $40 billion in 2007 and is growing by about $5 billion a year. It has the potential to rise to 600 billion euro. The US emerged as the largest consumer of organic products in 2007 at $21.2 billion, including $20 billion alone for organic food and drinks. According to the Organic Trade Association (OTA), sales of organic products in the US are likely to increase to $25 billion in 2008. The area under organic farming is gradually increasing as the Farm Bill 2008 assures to increase the spending on the organic sector from $20 million to $112 million. Germany emerged as the second largest market for organic products in 2007 at 5.3 billion euro.

My Fear

My dear friend Color Pencil invites me to write about my fear.

I am a man in my late 20s. I have great position for continue my study; a wide circle of friends and life is good. My main fear is about environment. All these issue is my fear and I just thinking to resolve these problems. The major environment and resource issues—population growth; climate change; agriculture and food supply; our fisheries, forests, and fossil fuels; water and air quality;  solar and nuclear power, deforestation, air pollution, land degradation,  clean water, adequate energy supplies, public health, global warming, genetically modified foods, automobile and transportation technologies, and the highly significant Endangered Species. I hope I can resolve even small part of these problems.

Recently I start a neat friendship with one kind girl.  I don’t know what will happen to this relationship. I am very worry about this relationship. Maybe I can not satisfy her and she becomes sad or reverse. i would like to make happy everyone around me.

“The oldest and strongest emotion of mankind is fear.”

Thank you my dear friend  Medad Rangi for invitation

I wound like to invite my dear friend Persianeyes, Khomkhane Vahdat, and ma va mochul to write about their fear.

Pesticides more dangerous than thought

U.S. scientists studying 10 of the world’s most popular approved pesticides say, when combined, the chemicals caused 99 percent mortality in tadpoles.

University of Pittsburgh researchers said the U.S. Environmental Protection Agency-approved pesticides, when mixed together, can decimate amphibian populations even if the concentration of the individual chemicals is within limits considered safe.

Such “cocktails of contaminants” are frequently detected in nature, the scientists said, noting their findings offer the first illustration of how a large mixture of pesticides can adversely impact the environment.
