After two decades of planting glyphosate-tolerant crops, resistant
weeds have overtaken farm fields across the U.S., leaving farmers to
battle an increasingly difficult situation. At least 35 weed species are
now resistant to glyphosate, the primary ingredient in Monsanto's broad-spectrum herbicide Roundup.1
Studies2
have also linked glyphosate to increases in Sudden Death Syndrome
(SDS), a deadly plant disease that causes plants to turn yellow and die —
including crops that have never been sprayed with the herbicide but
were planted in a field that received an application the previous
season.
In an effort to skirt disaster, Monsanto developed a new breed of
genetically engineered (GE) seeds tolerant to other pesticides besides
Roundup. This, they claim, is the answer to rising weed resistance — a
side effect the company said would not occur from the use of their GE
seeds in the first place.
We now know, without any shadow of a doubt, they were wrong. And
there's every reason to believe they are wrong about their next
generation of GE seeds as well. If anything, it will likely boost weed
resistance, continue driving the increase in pesticide use and make our
food even more toxic.
Monsanto Makes Another Massive Mistake
Earlier this spring, Monsanto released a new crop of soybean and
cotton seeds called Roundup Ready Xtend, designed to tolerate being
drenched in not just glyphosate-based Roundup but also dicamba, an older
and highly toxic herbicide known for its tendency to cause unintended crop damage. As noted by Mother Jones:3
"[T]he dicamba products currently on the market are highly volatile — that is, they have a well-documented tendency to vaporize in the air and drift far away from the land they're applied on, killing other crops.
Monsanto's new dicamba, tweaked with what the company calls 'VaporGrip' technology, is supposedly much less volatile."
Alas, while the U.S. Department of Agriculture (USDA) had approved
the seeds, the U.S. Environmental Protection Agency (EPA) had not yet
signed off on Monsanto's "new and improved" glyphosate/dicamba
formulation to be used on them.
At present, the use of dicamba on cotton and soybean crops is
restricted to pre-planting or post-harvest burndown applications only.
It is illegal to spray dicamba on the crop itself.
It would have
been prudent to not sell the seeds until the, allegedly, safer and less
volatile dicamba formulation was approved and ready for market, but
Monsanto decided not to wait, thinking farmers could simply use Roundup
in the meantime.
However, facing an infestation of pigweed, which has developed
resistance to Roundup, farmers took to illegally spraying older dicamba
products on their brand new Roundup Ready Xtend plants, thereby setting
off a chain reaction of crop decimation.4
According to the EPA, crop damage and crop losses blamed on dicamba
drift have been reported in 10 states: Alabama, Arkansas, Illinois,
Kentucky, Minnesota, Mississippi, Missouri, North Carolina, Tennessee
and Texas.
In Missouri, 117 complaints "alleging misuse of pesticide products
containing dicamba" have been filed. The illegal use of dicamba has
affected more than 42,000 acres of a diverse array of crops, including
peaches, cantaloupes, watermelons, rice, peas, tomatoes, peanuts,
alfalfa, cotton and soybeans.
Arkansas Considers New Dicamba Rules to Protect Crops From Drift Damage
In response to 25 formal complaints over dicamba drift damage,5
the Arkansas Pesticide Committee has brought forth a proposal to expand
mandatory buffer zones and outright ban the use of certain dicamba
products during the growing season, from mid-April until mid-September.
Fines may also be raised to dissuade illegal spraying.6
When asked what actions Monsanto would take against the farmers who
used their product with an illegal herbicide, they told the Northwest
Arkansas Democrat Gazette7 that revoking farmers' licenses for product use was "difficult if not impossible."
"For its part, Monsanto says it expects the EPA to approve the new,
improved dicamba formulation in time for the 2017 growing season, and
that it never expected farmers to use old dicamba formulations on the
dicamba-tolerant crops it released this year," Mother Jones writes.
"If the VaporGrip formulation does indeed control volatization as
promised, the drift incidents of 2016 will likely soon just be a painful
memory for affected farmers. If not, they portend yet more trouble
ahead for the PR-challenged ag giant."
Environmental Groups Predict the Worst Is Yet to Come
Meanwhile, environmental groups like the Environmental Working Group
(EWG) and Save Our Crops Coalition (a "grassroots coalition of farm
interests organized for the specific purpose of preventing injury to
non-target plants from exposure to 2,4-D and dicamba"8) are not surprised with the present chain of events.
In a recent blog post, EWG agriculture policy director, Colin O'Neil, and research analyst Emily Cassidy write:9
"[On August 9, 2016] Steve Smith, chair of the Save Our Crops Coalition, wrote an open letter10 to Hugh Grant, Monsanto's chairman and chief executive officer, that said, essentially, we told you so.
For years, the Save our Crops Coalition … has warned that illegal
use of generic dicamba would occur and that dicamba drift would be
especially hazardous. Now it appears that environmentalists' worst fears
are coming true. This situation is likely to only get worse. What can
be done?
For starters, Congress should update the nation's outdated federal
pesticide law to ensure that there are adequate buffer zones around
neighboring farms, schools, hospitals and churches, as well as mandate
stricter enforcement and higher penalties for non-compliance.
Congress should also reward good stewardship … [T]he incentives
created by Congress are backward. The federal government does not give
enough support to reverse these damaging practices.
One thing is clear: If pesticide regulation continues
to be a Wild West, then farmers and consumers can expect pesticide
drift to expand."
Dicamba Likely to Worsen Toxicity of Food Supply
According to research11
published in 2014, phenoxy herbicides, which include 2,4-D and dicamba,
are clearly associated with three distinct types of non-Hodgkin's
lymphoma (NHL), a type of blood cancer that originates in your lymphatic
system.
It's the sixth most common type of cancer in the U.S., with an
estimated 69,000 Americans diagnosed each year. Worldwide, NHL accounts
for an estimated 37 percent of all cancers.
Besides cancer, other documented health hazards associated with these
herbicides include developmental and reproductive problems. This is
particularly chilling considering the fact that use of these herbicides
have risen several-fold since the early 2000s, and their use will
increase even further now that 2,4-D and dicamba-tolerant crops have
been approved. (Dow AgroSciences' Enlist corn and soybeans are resistant
to glyphosate and 2,4-D.)
Monsanto Betting Big on Dicamba
In April 2016, Monsanto announced a $975 million expansion plan for
its Luling, Louisiana facility where dicamba is produced. As with its
Roundup Ready seeds, the primary reason for creating these genetically
modified (GM) seeds it to expand the market for the chemicals that go
with them.
For decades, Roundup ruled supreme, becoming the most commonly used
weed killer in the world. Now, Monsanto is betting on dicamba,
apparently without much thought to the health and environmental effects
it will wreak as farmers start to douse our food supply with both
glyphosate (recently classified as a probable human carcinogen)
AND dicamba (which despite its known toxic profile can be found in over
1,100 different weed killer formulas sold in the U.S.)
After all, volatility and drift is not the only hazard with dicamba.
Whether Monsanto's "VaporGrip" formula works or not, this chemical poses
health and environmental threats over and above those of glyphosate. I
shudder to think what scientists may find in the years to come when they
start investigating the synergistic effects of this Roundup/dicamba
combination on health.
What's certain is that Monsanto will do everything it can to make
dicamba the new go-to solution, just like Roundup was before its serious
health and environmental hazards became more widely known. As reported
by Mother Jones:12
"Within a decade, the company wrote, the new GM crops will
proliferate from the U.S. Midwest all the way to Brazil and points
south, covering as much as 250 million acres of farmland (a combined
land mass equal to about two and a half times the acreage of California)
— and moving lots of dicamba."
Signs and Symptoms of Dicamba Exposure
Dicamba (as well as 2,4-D) acts like auxins — natural plant hormones
that control plant growth. When a plant is treated with dicamba, it
begins growing in abnormal ways, typically resulting in plant death. As
mentioned, dicamba has a long history of use as a weed killer both in
agriculture and other places, such as lawns, golf courses and along
roadsides. Exposure can occur via inhalation or skin contact. Signs and
symptoms of dicamba exposure include:13
Dizziness
Coughing
Skin irritation
Vomiting and loss of appetite
Muscle spasms
Signs that your pet may have been exposed, either by eating
treated plants or walking through an area where dicamba has been applied
include:
Shortness of breath
Muscle spasms
Excessive saliva production
Birds may exhibit signs of wind drop, loss of motor control and weakness.
Pesticide Cocktails Threaten Human and Environmental Health
In this 37-minute video, Charles Benbrook, Ph.D., an American
agricultural economist and former research professor at the Center for
Sustaining Agriculture and Natural Resources at Washington State
University, discusses the use of GE crops and how they affect your
health and environment.
Originally marketed as a means to reduce the use of pesticides, GE
crops have led to the creation of resistant weeds and an increased use
of chemicals to control them. Just as bacteria can develop a resistance
to antibiotics, so can weeds develop a resistance to herbicides.
Stacked trait refers to the combination of two or more genetically
engineered genes spliced into a single plant. Monsanto's Roundup Ready 2
Xtend seeds is one example. The seeds are engineered to tolerate both
Roundup and dicamba. But will stacked trait plants actually slow down or
even prevent resistance? Hardly. The more likely scenario is that it
will simply speed up the process of resistance, making more weeds
resistant to more chemicals.
There's also the problem of synergy, which is what happens when two
or more compounds combine to create an effect that is larger than the
sum of their parts. Research shows that combining two chemicals
increases the toxic effect compared to using each chemical in isolation.
In the past, the EPA has claimed it could not assess the potential
synergistic effect of the chemicals without data.
However, in late 2015, the EPA discovered that synergistic chemical
reactions were actually recorded in patent applications at the U.S.
Patent and Trademark Database. Nathan Donley, a scientist with the
Center for Biological Diversity, told EcoWatch:14
"It's alarming to see just how common it's been for the EPA to
ignore how these chemical mixtures might endanger the health of our
environment. It's pretty clear that chemical companies knew about these
potential dangers, but the EPA never bothered to demand this information
from them or dig a little deeper to find it for themselves."
Tips to Help You Avoid Pesticides
Research has linked long-term pesticide exposure to infertility, birth defects,15,16 endocrine disruption,17 neurological disorders18 and cancer.19
It is only a common sense conclusion that ingesting and being exposed
to fewer pesticides would result in improved health. Here are some basic
suggestions to help you reduce the amount of pesticides you and your
family are exposed to.
• Eat organic foods.
In a survey of 1,000 Americans, 71 percent expressed a concern over the
number of chemicals and pesticides in their food supply.20
If you're among them, the best strategy at your disposal is to buy
organic produce, pastured, organic meats and dairy products.
Investigate the farmers markets in your area and consider planting
your own garden to supply produce through the summer months. Although
buying organic foods may be slightly more expensive today, they help to reduce your overall health costs in your future.
If you cannot afford buying everything organic, print out the EWG's
2016 "dirty dozen" list for most pesticide-contaminated fruits and
vegetables. These you'll want to buy organic. You can purchase the
conventional versions of produce that tend to be the least contaminated,
thereby spending the extra money where it counts the most. You can find
the EWG's 2016 Dirty Dozen and Clean 15 lists in my previous article, "Which Fruits and Vegetables Have the Most Pesticides?" • Clean up your lawn and garden care.
Don't apply chemical pesticides or herbicides to your yard, and if you
use a lawn care service, don't allow them to use them. Remember that a
neighbor's lawn chemicals can potentially contaminate your property as
well. Also avoid lawn care and other gardening products that contain
insect growth regulators (IGRs), especially if you have pets.
The
focus of organic lawn care is to produce a healthy lawn and soil using
natural organic fertilizers. An organic lawn has grass roots grown deep
into the soil, which makes them less vulnerable to drought, weeds,
insects, disease and other stressors. There are many excellent online
resources about how to naturally control weeds and improve soil health,
and in many communities' organic lawn care services are readily
available.
The same goes for pests. Ants, wasps and other bugs can
all be safely combated. Boric acid powder, for example, has been found
to be a very effective deterrent to roaches and ants. Sprinkle some in
the inner corners of your cabinets and in the corners under your
cabinets.
Pests will carry it back to their nests on their feet and kill the
remainder of the infestation. Boric acid is non-toxic for animals and
only kills the insects. For natural pest solutions, check out the book
"Dead Snails Leave No Trails" by Nancarrow and Taylor. • Talk with your school board about lawn care at your children's school.
Pesticides sprayed on the school lawn and play areas can increase your
child's exposure. You may be able to change how they care for the lawn
when you educate the administration about the risks involved to the
children. • Play in a healthy environment.
Before joining a golf club, talk with the course superintendent about
the pesticides they use to control weeds and insects. Bring members
together to request cleaner and safer lawn care. Talk to your city
administrators about the care given to the lawn in your local parks.
Educate them about the risks to adults, children and pets from
pesticides.
