Reports are coming from all over Brooklyn that the NYC Parks Dept. has been spraying the deadly organophosphate herbicide Round-Up -- Monsanto's hugely profitable poison (the #1 selling herbicide in the world) -- around parks to kill weeds growing between the cracks in cement, and on lawns, etc.
This is the same herbicide being sprayed by aircraft all over Colombia, and on Argenina's genetically engineered Roundup Ready soy crops.
Connie Lesold in Prospect Heights, Brooklyn first noticed the spraying and reported this (she saved the Warning sign as well), and next thing we knew the sidewalks perimetering children's playgrounds throughout Brooklyn had turned a putrid green. Now Carl Lawrence reports the same from his neighborhood in DUMBO (Down Under the Manhattan Bridge Overpass) and Brooklyn Heights.
Clearly this is a Brooklyn-wide Parks Dept. project. Any reports from the rest of NYC?
The No Spray Coalition will be advertising a call-in blitz to NYC government to protest this misuse of toxic herbicides (phone numbers will be forthcoming). We will also be meeting with City Council members and calling for hearings. Any additional ideas on how we should proceed?
ABOUT ROUNDUP / GLYPHOSATE:
The glyphosate, Roundup, is a noncholinesterase inhibiting organophosphorous herbicide. (Malathion, on the other hand, is a cholinesterase inhibiting organophosphate.)
Within the formulation, there are inert components such as surfactants that contribute to the activity of the mixture. Polyoxyethylene amine (POEA), is a major component of these surfactants and they are the major cause of acute mucosal erosions in the mouth and the upper respiratory tract. Intoxication may result from oral (ingestion) or respiratory (inhalation) exposures.
In addition, children (and adults) track the poison into the home. Wheel chairs kick it up into people's faces. Monsanto says that it will not affect people because glyphosate works on biochemical pathways that do not exist in people, but this is a very narrow, self-serving position (as is everything that Monsanto and the other agribusiness companies put out).
The OTHER chemical that the RoundUp is mixed with, Pendulum, is manufactured by BASF (26 Davis Drive, Research Triangle Park, North Carolina, 27709), and is composed of ACTIVE INGREDIENT: pendimethalin, N-(1-ethylpropyl)-3,4-dimethyl-2, 6-dinitrobenzenamine 38.7% and so-called INERT INGREDIENTS 61.3% (not listed)
These proportions may change depending on which of the 3 kinds of Pendulum they are using.
The label says NOT to use it in iirrigation. But then the label goes on to say that it works best when it is followed by rain (which washes it into sewers and into the rivers and oceans! -- they leave that part out).
Excerpts from the label for one kind of Pendulum:
This product is toxic to fish. DO NOT apply directly to water, to areas where surface water is present, or to intertidal areas below the mean high water mark. Drift and runoff from treated areas may be hazardous to aquatic organisms in adjacent aquatic sites. DO NOT contaminate water when disposing of equipment washwaters.

From: Carl Lawrence
I wanted to tell you that yesterday I witnessed a Parks Dept. spray truck in Cadman Plaza spraying with a huge spray spectrum Pendulum and Roundup herbicide all over the place-in a rain storm. Of course most of it went directly into the storm drains and on out into the harbor. They had dyed it yellow so it was easy to see it every where. Are they allowed to do this? I called 311 and was put on hold until I finally hung up the pay phone in frustration. A woman said they were "cleaning" the park. We should organize against this stuff and stop it. Please pass this along. Regards, Carl
GREENPEACE'S GLYPHOSATE FACT-SHEET
Glyphosate Fact Sheet
This fact sheet describes the basic properties of glyphosate and the issues surrounding glyphosate resistance and weed control. Glyphosate is a broad spectrum herbicide used to kill crop weeds. Monsanto's trade name for this is Roundup. Roundup Ready crops are engineered to withstand exposure to glyphosate. This allows applications of the herbicide after crop emergence, killing weeds but not Roundup resistant crop plants such as RRS (Roundup Ready Soybeans).
Chemically, glyphosate is an organophosphate like many other pesticides but it does not affect the nervous system as other organophosphates do. It is a broad spectrum, non-selective herbicide which kills all plants, including grasses, broad leaf and woody plants. It is absorbed mainly through the leaves and is transported around the whole plant, killing all parts of it. It acts by inhibiting a biochemical pathway, the shikimic acid pathway. At low levels of application it acts as a growth regulator.
There are three forms of glyphosate used as weed killers; glyphosate-isopropylammonium and glyphosate-sesquiodium patented by Monsanto and glyphosate-trimesium, patented by ICI (now Zeneca). Other common brand names are Rodeo, Accord and Vision.
Glyphosate is technically extremely difficult to measure in environmental samples. Only a few laboratories have the sophisticated equipment and techniques necessary. This means that data is often lacking on residue levels in food and the environment and existing data may not be reliable.
Use In Weed Control
Glyphosate product sales are worth $1,200 million a year. In the US, glyphosate was used on about 12-25 million acres annually in the 1980s. In the UK it was used on almost 800,000 acres in 1994. Because it is broad spectrum in action it is used to control a great variety of annual, biennial, and perennial grasses, sedges, broad leafed weeds and woody shrubs. It is used in fruit orchards, vineyards, conifer plantations and many plantation crops (e.g. coffee, tea, bananas); in pre-crop, post-weed emergence in a wide range of crops (including soybean, cereals, vegetables and cotton); on non-crop areas (e.g. road shoulders and rights of way); in cereal stubble; forestry; gardening and horticulture. Other uses of salts of glyphosate are in growth regulation in peanuts and in sugarcane to regulate growth and speed fruit ripening.
Because the shikimic acid pathway does not exist in animals, the acute toxicity of glyphosate is very low. Glyphosate can interfere with some enzyme functions in animals but symptoms of poisoning are only seen at very high doses. However, products containing glyphosate also contain other compounds which can be toxic. In particular most contain surfactants known as polyoxyethyleneamines (POEA). Some of these are much more toxic than glyphosate. These account for problems associated with worker exposure. They are serious irritants of the respiratory tract, eyes and skin and are contaminated with dioxane (not dioxin) which is a suspected carcinogen. Some are toxic to fish.
In California, glyphosate is the third most commonly-reported cause of pesticide related illness among agricultural workers. Glyphosate is the most frequent cause of complaints to the UK's Health and Safety Executive's Pesticides Incident Appraisal Panel. New formulations, with less irritating surfactants, have been developed by Monsanto (e.g. Roundup Biactive), but cheaper, older preparations are still available.
Glyphosate is one of the most toxic herbicides, with many species of wild plants being damaged or killed by applications of less than 10 micrograms per plant. Glyphosate can be more damaging to wild flora than many other herbicides, as aerial spraying with glyphosate can give average drifts of 1200 to 2500 feet and ground spraying with glyphosate may cause damage to sensitive plants up to 300 feet from the field sprayed. Glyphosate use is thought to affect hedgerow trees, causing die-back, and may reduce trees' winter hardiness and resistance to fungal disease
The direct toxicity of glyphosate to mammals and birds is low. However, its effect on flora can have a damaging effect on mammals and birds through habitat destruction. The US EPA concluded that many endangered species of plants, as well as the Houston toad, may be at risk from glyphosate use.
Fish and invertebrates are more sensitive to formulations of glyphosate. As with humans, the surfactants are responsible for much of the harm . Toxicity is increased with higher water temperatures, and pH. In Australia, guidelines state that most formulations of glyphosate should not be used in or near water because of their toxic effects on tadpoles and adult frogs. The newer, non-irritant formulations such as Roundup Biactive are not included in this advice.
Of nine herbicides tested for their toxicity to soil microorganisms, glyphosate was found to be the second most toxic to a range of bacteria, fungi, actinomycetes and yeasts. However, when glyphosate comes into contact with the soil it rapidly binds to soil particles and is inactivated. Unbound glyphosate is degraded by bacteria. Low activity because of binding to soil particles suggests that glyphosate's effects on soil flora will be limited. However, some recent work shows that glyphosate can be readily released from certain types of soil particles, and therefore may leach into water or be taken up by plants.
Impact Of Genetically Engineered Herbicide Resistant Crops
The introduction of crops engineered to be resistant to glyphosate could have two particularly damaging effects. Firstly, it will increase the use of the herbicide, and secondly, it may encourage the emergence of herbicide resistant weeds.
Monsanto claim that the introduction of herbicide resistant crops will reduce the overall amount of herbicide used. They argue that glyphosate will replace other, more environmentally damaging herbicides, because only glyphosate need be used rather than several different compounds. They also argue that weed killer will be used less frequently on resistant crops. Importantly they also consider glyphosate to be 'environmentally friendly' and a 'safe' herbicide, basing this claim on its reduced soil particle binding and low toxicity to humans.
Other herbicides used on soybeans and other crops are unquestionably harmful to the environment and human health. The question is whether glyphosate is really any less harmful and whether herbicide resistant plants will reduce the amount of potentially damaging chemical to the environment. Evaluating overall amount of use on a weight or volume basis does not allow for the differences in toxicity between chemicals. Weight or volume of total herbicide may decrease simply because glyphosate is more effective at killing plants than many other chemicals. Glyphosate is already the eleventh most widely used pesticide in the US on a volume basis. Its damaging impacts on the environment have already been described.
Whether there will be a reduction in the number of times herbicide is used is also questionable. In their documents prepared for the US authorities, Monsanto say that under current regimes, between one and five applications of different herbicides or herbicide mixtures are needed to control weeds in soybean crops, while with Roundup Ready soybeans only "one or possibly two" applications of Roundup will be needed. Yet in their information for farmers in Argentina, Monsanto recommends Roundup be used with Roundup Ready soybeans before sowing, when the young plant has three to four leaves and then whenever the farmers find weeds. This is "at least twice and probably more frequently".
Herbicide Resistance In Weeds
One of the major concerns of weed scientists is that the emergence of herbicide resistant weeds may be encouraged by the use of herbicide resistant plants. Herbicide resistance arises in an analogous fashion to the emergence of antibiotic resistance in bacteria. Mutations occur in plants and when one arises which makes it resistant to the herbicide, it will have an advantage and grow and flourish when other plants are killed Resistance to glyphosate is easy to induce in plants in the laboratory. Monsanto claims resistance to glyphosate is unlikely to emerge in the field because it does not persist in soil. However, weed resistance to paraquat, an herbicide which has a shorter soil persistence than glyphosate, is already a serious problem. One weed specialist concluded, by comparison to paraquat, that "Presumably glyphosate resistance can also be obtained with multi-annual treatments" (Gressel, in Cassley et al, 1991). Roundup Ready soybeans are intended to be used with "multi-annual treatments" and so the emergence of resistance will be encouraged. Even before the increased use of glyphosate expected with the introduction of resistant crops, there has already been a report of glyphosate resistance in a weed which occurred in ryegrass in Australia.
Glyphosate resistant weeds could also arise if there is gene flow between the soybean and a related wild plant or if the soybean survives to emerge as a weed ("a volunteer") in the subsequent crop. Gene flow is possible in the Far East where soybean originated and wild related plants exist. Herbicide resistant volunteers may be a problem where mild climates occur and overwintering of soybean is possible.
Herbicide resistant crops are an expensive problem for farmers. Having weeds resistant to another herbicide, triazine, have been estimated to cost farmers up to $10 an acre in extra weed control expenditure. There would be an extra penalty for farmers growing glyphosate resistant crops if glyphosate resistant weeds evolved, because not only would they have to change their weed control practices but they would have paid a premium for the herbicide resistant seed in the first place.
Thus herbicide resistant soybeans promise increased herbicide use and associated damage to the environment, together with an increased risk of weed resistance, which would be a costly problem for farmers.
