Organic Fertilizer Is Great at Killing Bees

Posted on April 21, 2016 by Ruth Kava

A given of the organic agriculture movement is that organic growers don’t use synthetic pesticides and fertilizers, like organophosphates and glyphosate (RoundUp). All that fear-mongering about pesticides is only possible because environmental groups only test for the synthetic kind, they don’t test for the pesticides and fertilizers used by organic growers.

Because those are safer? Absolutely not.

In the Journal of Economic Entomology, Brazilian scientists studied the effects of copper sulfate, a fertilizer and pesticide that is approved in the U.S. for use in organic agriculture and applied to the leaves of crop plants. Obviously the smarter approach is to treat seeds instead of using a broad spectrum pesticide, and that is the premise behind neonicotinoids, which environmental groups also protest — by treating seeds, which bees have no interest in, rather than plants, which bees do have an interest in, farmers get better yields with less environmental impact.

So why do organic farmers insist on carpet-bombing plants with chemicals instead? The science is clearly against them, so it’s for psychologists to figure out. The new paper adds to the literature showing that a targeted approach is just better, not just for honeybees, but also for stingless bees (Friesella schrottkyi), which are native to the Americas and not an introduced species like the honeybee. They are known to pollinate crop plants.

What did they find? The organic pesticide approach is incredibly toxic for bees.

The investigators compared the effects of copper sulfate and another leaf fertilizer mixture, as well as a commonly used insecticide (spinosad) on the stingless bees. They found that the copper sulfate was more lethal to the bees than the insecticide when the insects ingested it in a sugar solution.

They wrote: “[L]eaf fertilizers seem to deserve attention and concern regarding their potential impact on native pollinators, notably Neotropical stingless bees such as F. schrottkyi. Their heavy metal content is above the safety threshold for the stingless bee species studied, which may also be the case for related species. Furthermore, the mix of heavy metals in some leaf fertilizers and the presence of S[ulfur] and sometimes B[oron] may increase their risks. In sum, leaf fertilizers deserve proper risk assessment because of the isolated and mixed use of heavy metals in such fertilizers.”

So, the next time you read organic marketing claims about how synthetic pesticides and fertilizers are dangerous, be a little more skeptical. When they are applied by spray, there’s really no reason to distinguish between the two types.

For bee alarmists, Groundhog Day comes in June

Will activists finally admit their sins and break out of their pesticide-blaming time loop?

Paul Driessen

Did you think Goundhog Day only comes in February?

For anti-insecticide zealots and others in the environmentalist movement who’ve been preoccupied for years with bees and “colony collapse disorder,” it actually comes every June.  That’s when the Bee Informed Partnership – a University of Maryland-based project supported by the US Department of Agriculture (USDA) – releases the results of its annual survey of honeybee colony losses and health.

In Bill Murray’s 1993 “Groundhog Day” movie, cynical TV weatherman Phil Connors is condemned to relive the same day over and over in a little Pennsylvania town until he learns the right “life lessons.” Each June, eco-campaigners work themselves into a carefully orchestrated lather over bee losses, getting caught in a time loop of endlessly repeating the same false and misguided claims about the BIP report.

Last week’s BIP report predictably garnered the usual hyperventilating headlines, sounding almost as alarming as in recent years. The 38% 2018-19 over-winter colony loss rate was the highest in the 13 years the survey has been taken. Combined with in-season (summer) honeybee colony losses of 20.5% this yielded an overall annual loss rate of 40.7% (computed using a special BIP methodology).

That’s slightly higher than 2017-18’s reported 40.1% overall loss rate and 2.9% higher than the average annual loss rate calculated since 2010. Hit the panic button.

Environmental worrywarts moved seamlessly into their annual spasm of anxiety and dire prognostication.  “Honey bees are no longer disappearing suddenly and mysteriously. They’re dying persistently, and in plain sight,” the Washington Post lamented.

Will there be enough honeybee colonies left to pollinate California’s lucrative almond crop next winter? an environmental “investigative news organization” agonized. (Ironically, but predictably, this story was posted four weeks after the USDA predicted another record almond harvest in the state.)

Is the BIP report further evidence that the hyperventilating media and eco-campaigners were correct about the “bee-pocalypse” they’ve been “documenting” for the last half-dozen years? Hardly!

First, the alarmists who routinely over-react to the annual BIP survey forget (or ignore) its limitations. As the report makes clear, the survey is entirely voluntary, returned by beekeepers who take time to fill it out. It consequently does not even purport to be a scientific sampling of American beekeepers. It is a compilation and analysis of responses from those who voluntarily self-report. The results show this.

The roughly 4,700 beekeepers who responded this year account for only about 12% of all US honeybee colonies. Professor Dennis Van Engelsdorp – founder of the Bee Informed Partnership  – showed in his own research that hobbyist and small-scale beekeepers (who account for the majority of the BIP respondents) have more severe parasite and pathogen infestations of their honeybee hives than large-scale commercial beekeepers. That increases colony loss rates.

Interestingly, while BIP survey results go up and down from year to year, the overall trend line over the survey’s first dozen years has been downward. But that may reflect small-scale beekeeper experiences.

In any case, US honeybee colony numbers aren’t shrinking; they’re growing, regardless of what the latest BIP survey results find. The USDA’s actual census of beekeepers and their colonies – which actually is systematic and scientific – shows that the overall number of US honeybee colonies grew by 4% in 2018.

Indeed, in releasing the latest BIP results, Van Engelsdorp himself said, “We’re not worried about honeybees going extinct.  We’re worried about commercial beekeepers going extinct.” Hive infections, long distance travel and other aspects of the business have driven more beekeepers to other professions.

Second, there’s good news in the latest Bee Informed Partnership survey. Finally, after years of misleading media and activist rhetoric seeking to pin the blame for honey bees’ problems on agricultural pesticides –neonicotinoid insecticides in particular – attention is now focusing where it should have been all along: on Varroa destructor mites. These tiny, nasty critters and the multiple virulent diseases they spread to honeybee colonies are the foremost scourge of our beloved, and vital, insect pollinators.

This year’s BIP survey announcement and most of the resulting press coverage emphasized this point.

It’s about time. Neonics have become the world’s most widely used insecticides because they work – and pose minimal risks to bees. Some are sprayed on fruits and vegetables, but nearly 90% are used as seed coatings for corn, wheat, canola and other crops. They are absorbed into plant tissues as crops grow.

That means they target only pests that actually feed on the crops, particularly during early growth stages. Since they don’t wash off, they reduce the need for multiple sprays with insecticides that truly can harm bees, birds, fish, other animals and non-pest insects. And they are barely detectable in pollen and nectar – which is why neonic residues are well below levels that can adversely affect bees.

That makes it ironic, and outrageous, that relentless anti-pesticide campaigners – especially those who profess to be alarmed about the “plight of the bumblebee” and want to ban neonics – have said virtually nothing about Varroa mites. Nor have they proposed any plan to deal with this scourge.

Thankfully, recent USDA research has identified a promising new approach of using RNA interference (RNAi) to disrupt the reproduction of another bee parasite, Nosema ceranae – the honeybee’s second-worst scourge. USDA is also reporting progress in efforts to breed more Varroa-resistant or Varroa-tolerant honey bees, which somehow have better hygienic habits: removing mites from one other.

Activists and journalists concerned about bees and pollinator health should have focused on this all along – particularly since available Varroa treatments no longer work as well, due to the mite’s uncanny ability to develop resistance to treatments. Instead, years of energy and millions of dollars have been wasted pursuing a wrong-headed crusade against neonic insecticides that are irrelevant to any challenges facing honey bees and other pollinators. 

Phil Connors finally escaped from his time loop after he ended his disdain for small town Punxsutawney, began performing good deeds and told Rita he truly loved her. Maybe now – finally – self-professed bee advocates and environmental crusaders will wake up from their Groundhog-Day-in-June time loop and devote some time, effort and honesty to addressing the real problems that affect honey and wild bees.

Maybe they will also stop treating modern conventional farming like an evil pariah, and organic farming like a planetary savior. Maybe they will stop repeating the organic food industry’s Big Lie: that it doesn’t use pesticides. In fact, as Professor David Zaruk explains on his RiskMonger.com website, organic farmers employ a dozen highly toxic “natural” pesticides and over 3,000 other “approved” pesticides.

Several are highly toxic to bees: acetic acid, copper sulfate, pyrethrins, hydrogen peroxide, azidirachtin, rotenone, citronella oil, eucalyptus oil and garlic extract, and spinosad. Several are very toxic to humans: boron can affect people’s brain, liver or heart; rotenone has been linked to Parkinson’s disease; nicotine sulfate is a neurotoxin that has actually killed several gardeners; and copper sulfate can readily and severely injure a user’s brain, liver, kidneys, stomach and intestinal linings, skin and eyes ... or even kill!

But again, Varroa is the villain, the real, enduring threat to bees – not pesticides, synthetic or organic.

Unfortunately, persuading environmentalists to acknowledge these realities is not likely. They have too much ideology, power and prestige invested in their campaigns against synthetic pesticides and conventional farming – to say nothing of the billions of dollars they’ve gotten from organic interests.

Bottom line? Lies, deception and fraud are unethical, immoral and illegal no matter who engages in it, devises the strategies or finances the campaigns. These environmentalist campaigns have been employed over and over because they work – and because too many legislators, regulators, judges and journalists have repeated, approved and applauded them. It will be an uphill battle to change that dynamic.

Let’s hope a few brave lawmakers start applying the same standards of truth and ethics across the board.

Scientists challenge Center for Biological Diversity report claiming wild bees near extinction

Richard Levine | April 4, 2017 | Genetic Literacy Project

The headlines, even after years of often-hyperbolic reports about an impending ‘beepocalypse’ and other bee health problems, were startling. “Hundreds of North American bee species face extinction: study,” wrote Reuters. Others, like Voice of America, published similar articles. TIME Magazine even produced a video to accompany an article titled “More than 700 North American Bee Species Are Headed Toward Extinction.”

What prompted this sudden burst in journalistic angst? The articles were based on a report released by the Center for Biological Diversity (CBD) in early March, “Pollinators in Peril: A systematic status review of North American and Hawaiian native bees.” According to its solo author—Kelsey Kopec—749 North American wild bee species are in decline and almost half of them are at serious risk of extinction. The culprits? Habitat destruction, pesticide use, climate change, and urbanization. The CBD called it a comprehensive, “first-of-its-kind analysis.”.......To Read More.....
