DeltaGard: worrisome specifications

Even if your street isn’t sprayed, don’t think you don’t need to take precautions!

A nearby DeltaGard applicator specialist working with Bayer products and with several decades’ experience in the business, but who does not wish to be identified, tells us the spray can drift 300 feet and does not tend to dissipate into the air. Of course, exactly where it goes depends on wind direction and speed. The manufacturer’s information documents high mosquito kill rates at 300 and even 400 feet.

A 2015 EPA memo (download here: EPA deltamethrin-mosquito-adulticide takes as well-founded Bayer’s “mortality” rate as “100% for deltamethrin, even at 300 feet from the point of application.”

This is why we are calling for a buffer zone of at least 300 feet around vulnerable non-targets, such as children in schools and day care centers, registered hypersensitive individuals, bee hives, and bodies of water where fish and amphibians are sickened or killed by pesticides. If mosquitoes are exterminated at that distance, the toxins are a danger to other species as well, including humans, and we know that smaller children are more vulnerable than most adults.

The above-mentioned mortality rate, as the EPA points out, is for “easily controlled” mosquito species as opposed to “those with more widespread resistance to organophosphates and/or pyrethroids.” Naturally, the more that mosquitoes are sprayed with a given pesticide, the more they become resistant to it. Such acquired resistance is a very good reason not to spray at all unless there is a serious health emergency, which becomes more likely as our climate warms and new-to-us mosquito-borne diseases move our way.

You can download the manufacturer’s (that’s Bayer) label for this product here: DeltaGard [label – mosquitos]. Note that this is specifically for the wide-area mosquito spray; other labels yo might see may pertain to other DeltaGard products.

The various DeltaGards all have deltamethrin as their active ingredient, but concentration and added ingredients may differ. See our earlier remarks on “turf and ornamental” DeltaGard here.

This is not easy reading but let’s focus on:

to control adult mosquitoes, black flies, gnats, non-biting midges, stable flies, horse flies, deer flies, sheep flies, horn flies, and nuisance flying insects such as houseflies or blow flies.

It’s hard to love all those insects, but let’s point out that they are part of nature and are important food sources for birds, other insects, reptiles, and amphibians. And those others flying around outdoors have no health implications for people.

• For best results, apply when insects are most active and meteorological conditions are conducive to keeping the spray cloud in the air column close to the ground. An inversion of air temperatures and a light breeze is preferable. Application during the cooler hours of the night or early morning is recommended. Apply when wind speed is equal to or greater than 1 mph.

Who has an anemometer when you need one? If you do, please set it up if spraying occurs! And how do we tell if there is a temperature inversion (meaning warmer air over cooler air)? Of course, those who wish the spray to remain concentrated at ground level want an inversion; the rest of us would be happy with the normal pattern, causing the spray to dissipate more rapidly. Meteorological help needed!

ENVIRONMENTAL HAZARDS

This product is extremely toxic to fresh water and estuarine fish and invertebrates. Runoff from treated areas into a body of water may be hazardous to fish and aquatic invertebrates.

Do not apply over bodies of water (lakes, rivers, permanent streams, natural ponds, commercial fish ponds, swamps, marshes, or estuaries), except when necessary to target areas where adult mosquitoes are present, and weather conditions will facilitate movement of applied material away from the water in order to minimize incidental deposition into the water body. Do not contaminate water when disposing of equipment rinsate or wash waters.

When used for mosquito adulticiding;

This pesticide is highly toxic to bees exposed to direct treatment on blooming crops or weeds. Do not apply this product or allow drift when bees are foraging the treatment area, except when applications are made to prevent or control a threat to public and / or animal health determined by a state, tribal, or local health or vector control agency on the basis of documented evidence of disease causing agents in vector mosquitoes, or the occurrence of mosquito-borne disease in animal or human populations, or if specifically approved by the state or tribe during a natural disaster recovery effort.

Please record any application over or next to bodies of water! Let’s bear in mind the condition that “weather conditions will facilitate movement of applied material away from the water in order to minimize incidental deposition into the water body.”

Rain or thunderstorms will do the opposite: wash the pesticide, both airborne and deposited on streets and other drainage areas, downhill and directly into surface drainage. If you ever see that happen, please photo the drainage water with a time stamp. Those fresh water fish and invertebrates are important ecological factors!

One more poison to fight!

“The EPA Says Farmers Can Keep Using Weedkiller Blamed For Vast Crop Damage, by Dan Charles, NPR, November 1, 2018

For months, farmers from Mississippi to Minnesota have been waiting for the Environmental Protection Agency to make up its mind about a controversial weedkiller called dicamba. Some farmers love the chemical; other farmers, along with some environmentalists, consider it a menace, because it’s prone to drifting in the wind, damaging nearby crops and wild vegetation.

This week, on Halloween evening, the EPA finally announced its decision. Calling dicamba “a valuable pest control tool,” it gave farmers a green light to keep spraying the chemical on new varieties of soybeans and cotton that have been genetically modified to tolerate dicamba.

A coalition of environmental groups that had filed a lawsuit against the EPA’s original approval of dicamba blasted the decision to keep it on the market. Paul Achitoff from Earthjustice said in a statement that “EPA’s disregard of both the law and the welfare of … species at risk of extinction is unconscionable.”…

Save the pollinators!

email from Friends of the Earth, 3/9/18. [N.b. Bayer also manufactures permanone, one of today’s mosquito sprays of choice. And, believe it or not, “In 1898, the Bayer pharmaceutical company began an aggressive marketing campaign to sell its commercial preparation of Heroin” (Narcanon; and search other sources). Who would trust such a company with our health and environment?]

Bayer the Bee-Slayer and Monsanto the Butterfly Killer are trying to merge into one giant pesticide corporation.

This would be a disaster for pollinators, people and the environment. Farmers overwhelmingly think this mega-merger is a bad idea — a new poll found 93 percent of farmers surveyed oppose it. Over 1 million Americans have called on the Justice Department to stop it. And there are investigations in both the EU and the U.S.

We need to make sure the Department of Justice doesn’t let this merger move forward. But we need your help to urge it to act.

Tell the Department of Justice to stop the Bayer-Monsanto merger!

If this merger goes through, the new company would be the world’s largest vegetable seed company. It would control seeds for many of the crops we eat regularly — including broccoli, carrots and onions.

It would also be the largest manufacturer and seller of herbicides. It would double down on making toxic chemicals like glyphosate (a.k.a. Roundup®) — which is a key culprit in monarch butterfly declines and is a probable human carcinogen.

What’s more, this merger threatens the development of a sustainable and just food system. It will hurt independent family farmers and rural economies and will encourage farmers to ramp up the chemically intensive agricultural system that Bayer and Monsanto promote.

In short, we’d be giving a single corporation unprecedented control of our food supply. We can’t let the future of our food system be handed over to Bayer and Monsanto.

The Department of Justice has the power to stop the proposed merger — but it won’t act unless you speak up.

Tell Bayer to save the honeybee

Petition for League of Conservation Voters members:

TELL BAYER TO SAVE OUR NUMBER ONE FOOD SECURITY GUARD — THE HONEYBEE!

Thank you for taking our quick survey. We at LCV agree that we need Bayer to stop manufacturing their bee-killing chemicals and find safer alternatives. But they will only change their ways if we speak out now.

Please join thousands of LCV members in sending a message to Bayer CEO Marijn Dekkers and tell him to stop producing chemicals that are killing our bees!

Your Message

Protect our nation’s food security — stop producing chemicals that kill our bees

Dear Marijn Dekkers,

I am writing to urge you to stop producing the neonicotinoids that are killing our honeybees across the globe.

Honeybees may sound easy to dismiss, but they are directly responsible for pollinating nearly 100 varieties of fruits and vegetables, including produce like almonds, cranberries, avocados, and apples. In the U.S. alone honeybees pollinate more than one-third of the entire food supply and help to generate more than $15 billion in agricultural production each year!
