A lot of us have a love-hate relationship with our lawns. We love them when they’re lush. We hate them when they’re full of dandelions and
dead patches. It’s easy to have someone come out and spray pesticides to take care of weeds and bugs. But some people say it’s not necessary and could
do more harm than good. Rebecca Williams reports:

So, you might be using pesticides on your lawn right now. And of
course, the pesticide industry says that’s okay.

The industry says the chemicals are safe to use on the lawn if you use
them correctly.

Alan James is president of Responsible Industry for a Sound
Environment, or RISE. It’s a trade group for pesticide companies.

“If individuals or professional applicators read the labels and follow
labels, the likelihood of misuse of pesticides is virtually zero because the
labels provide all the information a consumer or professional needs to
apply products both efficiently and safely.”

But the problem is, not everybody reads the label.

Alan James says if you’re hiring someone to spray your lawn you should
make sure they’re certified and insured. You should also take your kids’
and pet’s toys off the lawn before they spray.

But a lot of people say there’s no point in using chemicals just to make
your lawn look good.

Jay Feldman is with the group Beyond Pesticides. He says of the 30
most common lawn pesticides, most of them are suspected by the
Environmental Protection Agency to cause cancer, birth defects or other health problems.

“There’s a range of adverse effects that are indicated as a part of the
pesticide registration program at EPA. EPA knows this information.
Why not remove pesticides from the equation, especially in light of the
fact that they’re not really necessary?”

There’s a movement to stop using pesticides in North America. Both
Ontario and Quebec have banned the sale and cosmetic use of
pesticides.

So if you’re not going to use pesticides, what do you do?

That’s a question Kevin Frank gets a lot. He’s an extension agent at
Michigan State University and an expert on lawns.

“I love to mow my lawn on the weekends because nobody can call me on
the phone or email me with questions.”

He’s been showing me green, healthy test plots of grass and some that
look sad and neglected. The scientists here have been working to find
ways to have good-looking lawns without a lot of chemicals.

Back in his office, Kevin Frank says he tells people they shouldn’t be
afraid to experiment.

“Do you have it in you to let it go for one season and see what happens?
And it could be ugly, so you’ve got to be prepared for that!”

He says a healthy, dense lawn is actually really good at fighting off
weeds and pests all on its own. So, how do you get a healthy, dense lawn
without a lot of chemicals? Frank says it might take a couple years to get
there. And it means going against conventional lawn advice.

“We’ve done a great deal of research here at Michigan State that runs
contrary to what I call ‘turf dogma’. You know: water deeply and
infrequently – and we’ve shown if you do it on a more frequent basis you
end up with a healthier plan overall.”

He recommends watering lightly – just 10 minutes – every day instead
of soaking the lawn once a week. Frank says it’s also good to fertilize
twice a year, use a mulch mower, and mow high instead of giving the
grass a buzz cut.

He says that could make your lawn so healthy, it might mean you won’t
need to spray or hire someone to spray your lawn.

He says the biggest adjustment in reducing pesticide use is managing
your expectations, and deciding how many weeds and bugs you can live
with.

Whose Grass Is Really Greener?

Many Americans love full, lush
lawns. Fertilizers and herbicides
might help. But there’s concern
about water pollution from lawn
chemicals. Julie Grant reports
that some experts say you can use
them, just don’t over-use them:

Molly Aubuchon and her husband Stefan Meyer aren’t sure
what they’re going to do. Their two little kids are running
around the yard. Stefan wants a lawn of thick, soft grass for
them to play on. But that’s not what he’s got.

Stefan: “As you can see, there’s no grass here.
I don’t know what some of this stuff is. Some kind of moss.
I think even the moss died, so now we have dead moss
that’s like yellow and brown.”

Molly: “It’s not attractive dead.”

Stefan: “No. I just think, when I’m out here cutting my grass,
I’m like, man, if I lived across the street, I’d be like, ‘hey look,
they’re cutting absolutely nothing again. They’re just running
that lawn mower over bare spots.’”

They see their neighbors, with those thick, green lawns,
spreading chemicals a few times a year. Molly and Stefan
don’t want to do that.

Molly: “Well, the fact that I’ve got kids running around here
all day. And the fact that it seeps into the water supply and
the rivers, that’s a concern to me.”

There are lots of people who are concerned about lawn
pollution. Lawns have gotten a bad wrap in some places –
because of the fertilizers and other chemicals people use on
them. In much of Canada, lawn chemicals have actually
been banned.

Lou DiGeranimo is General Manager of Water in Toronto.
He says lawn chemicals were damaging the water quality.

“People were over-fertilizing, they were using commercial
pesticides. That chemical ended up in the rivers and ended
up in the lake. We passed a bylaw that prohibited that.”

But some experts say the chemical bans in Canada are
extreme.

David Gardner is professor of turf grass at the Ohio State
University. He doesn’t think banning lawn chemical will do
anything to improve the environment.

“Based on the work that I have seen, based on the research
that has been conducted, I believe that if there is a unilateral
ban on the use of pesticides it will make absolutely no
impact on our environmental footprint.”

Gardner says compared to
other sources of pollution, like cars and over-use of
chemicals on farms, the impact of lawn care is miniscule.

Still, Gardner says people like Molly and Stefan can keep
nice lawns – without using a lot of chemicals.

He says you’ve got to cut the grass and water regularly.
He also recommends fertilizing lightly in the spring and more
heavily in the fall.

That’s what Gardner does at his house – and he uses only 6
to 8 ounces of herbicide a year.

“Putting it another way, if I were to go to a store and buy one
of those gallon jugs of ready-made herbicide, that would be
enough to last me for about 16 years.”

Gardner says the herbicide will hit its expiration date before
he has a chance to use it all.

But Molly and Stefan just aren’t sold. They don’t want to use
lawn chemicals just to appease the neighbors.

Stefan: “I just want to feel good about the way my yard
looks for my own satisfaction. I would like to cultivate some
grass that looks good, you know, with my hands.”

Besides, Stefan says, they don’t have the worst looking lawn
on the street and they’d just rather not add unnecessary
chemicals into the environment.

Stefan: “We don’t have the worst lawn on the street. Our
street is not that long. It’s only four blocks, five blocks long –
there’s a house down there and their yard looks worse than
ours.”

Interview: Action Against Atrazine

  • One lawyer wants a class action suit against the manufacturer of Atrazine, an herbicide used on crops (Photo by Rebecca Williams)

Atrazine is a weed killer. It’s
used by farmers in several crops,
basically because the herbicide is
relatively cheap and effective.
When Atrazine is used in the spring,
it sometimes ends up getting in
water – and in some cases at levels
above the government’s drinking water
standard – the maximum contaminant
level of three parts-per-billion.
Steve Tillery is an attorney in a
lawsuit against the manufacturer of
Atrazine – Syngenta – and Synenta’s
partner, Growmark. Tillery represents
water suppliers and he’s seeking class-
action status to represent all water
suppliers who’ve had to deal with Atrazine
contamination. Lester Graham talked to

Atrazine is a weed killer. It’s

When Atrazine is used in the spring,
it sometimes ends up getting in
water – and in some cases at levels
above the government’s drinking water
standard – the maximum contaminant
level of three parts-per-billion.
Steve Tillery is an attorney in a
lawsuit against the manufacturer of
Atrazine – Syngenta – and Synenta’s
partner, Growmark. Tillery represents
water suppliers and he’s seeking class-
action status to represent all water
suppliers who’ve had to deal with Atrazine
contamination. Lester Graham talked to
him about the lawsuit:


Lester Graham: Mr. Tillery, what’s this lawsuit about, if the level is less than the 3-parts-per-billion the government says is safe?

Steve Tillery: Well, actually, at different times of the year, Atrazine does in fact exceed the federal standard. The federal government refers to MCL – maximum contaminant level – and that’s the maximum, they say, a chemical should exist in the water supply to be consumed by people in the community. The maximum contaminant level for Atrazine is 3-parts-per-billion. Many times, throughout the Spring, throughout Illinois and other Mid-Western cities, the levels grossly exceed 3-parts-per-billion. So what happens is that the cities, the water districts, are required to pay large amounts of money to filter the water so it is below that level. In addition, some have gone to the expense of completely cleaning it out of their water supplies. So that it doesn’t exist at all. And they should, in our view, be entitled to reimbursement for the expenses that they have incurred for completely cleaning it out of their water supplies.

Graham: Scientists that worked, then, for the National Oceanic and Atmospheric Association told me that during the application season, during the Spring, that they measured levels of Atrazine exceeding the safe drinking water levels in the rain on the East Coast from all of the application in the Midwest. Rather than just cleaning it up, is this not a problem of too much Atrazine – maybe we limit the amount?

Tillery: Well, the issue is whether or not it should be banned completely. The European Union has done exactly that. For all of the reasons that people look at – scientists look at – this chemical and point to the adverse health affects, changes to the environment, all of those reasons, the Europeans banned it some years ago.

Graham: The defense in most cases like this is: this is a regulated product, the label is the law, if it isn’t applied correctly, it’s the applicator – the farmer’s – fault; and if it is applied according to the label, the government says it’s safe.

Tillery: Yeah, we’re not safe. For two reasons. First of all, it’s not a problem with farmers. Farmers are doing exactly what is on the label. They are applying it precisely the way the manufacturer says it should be applied. So they’re not the issue. The problem is the manufacturer. To the extent that we rely on federal regulators to do the right thing, we are misdirected in this instance. For many years, the relationship between Syngenta – the principle manufacturer of this chemical – and the EPA has been under close scrutiny. And I’m hopeful that it’s reevaluated and examined under this new administration. Big corporations, in this case from Switzerland, who come here and sell this and make enormous profits in this country selling this chemical – 77 million pounds a year, average. When they make that money, and they cause taxpayers to incur $400 million a year in expense throughout the US to clean up their mess, they should be the ones that come back and reimburse them. We aren’t asking for anything else besides that. We are asking for compensation to these cities who’ve incurred this expense. The people who create the mess should pay for its cleanup. People should not be drinking water with Atrazine in it, at any level.

Graham: Steve Tillery is an attorney seeking class-action status trying to make the manufacturers of Atrazine pay to clean up the water their product contaminates. Thanks for your time.

Tillery: Thank you for allowing me to come here and speak.

Graham: I’m Lester Graham.

The Buzz on Mosquito Repellants

  • A team is researching the next generation of bug sprays, some that may not be as smelly or as sticky as DEET (Photo by Lester Graham)

It’s summertime – sometimes known as
mosquito and tick season. For decades, bug
sprays with DEET have been the most effective
to keep those disease-carrying pests away.
But there are some new repellants on the
market – and even more to come. Julie Grant

It’s summertime – sometimes known as
mosquito and tick season. For decades, bug
sprays with DEET have been the most effective
to keep those disease-carrying pests away.
But there are some new repellants on the
market – and even more to come. Julie Grant
has the buzz on bug sprays:

Hot summer nights haven’t changed all that much since
1957. Sure, they’re selling sushi at ball parks these days.

(sound of baseball game)

But, for the most part, people are still using the same bug
spray.

DEET was designed in the 1950s for military use.
Stores started selling it soon after. At this kids’ baseball
game in northeast Ohio, there are as many opinions about
DEET and bug sprays as there are people.

Person 1: “I if I did use bug spray, I would use DEET. I heard that’s the
best.”

Person 2: “No, actually, I am concerned about any kind of chemical. I
don’t like to use it. I don’t think it’s necessary.”

Person 3: “I’ve been scratching all week.”

Julie Grant: “Why don’t you use it?”

Person 3: “Stinks.”

Person 4: “Probably looking for something without DEET, of course,
which is pretty much outlawed anyway.”

Child: “I have a bug bite on my neck.”


Person 4: “Yes, you do have a bug bite on your neck, which is why
we need to go look for something.”


Actually, DEET is not even close to being outlawed. It’s used
hundreds of millions of times each year – by backyard
barbeque-ers and soldiers, alike.

In all these years, there have been only fifty reports of skin
problems or seizures – and those were attributed to gross
overuse, and couldn’t be definitely connected to DEET.

But it is a plasticizer. If it touches your watch face, it will
smear the plastic. And that makes people a little nervous.

And while it does drive away a wide array of bugs, including
mosquitoes that carry West Nile Virus, DEET does not protect
against mosquitoes that carry malaria, or ticks that carry
lyme disease and rocky mountain spotted fever.

The worst thing about DEET for lots of people is that
stickiness and that evil smell.

Trisha Branden is a health editor with Consumer Reports
magazine. She says lots of people just don’t like using
DEET.

“But I think everyone has their own sensitivity, particularly
when it comes to the smell and feel of DEET. It’s better to
have some protection than none at all.”

Consumer Reports has surveyed bug sprays and crèmes on
the market.

They found that the higher the concentration of
DEET, the longer it protects you from bugs. At the highest
level, 98% DEET, it lasted half a day.
But some products contain as little as 7% DEET because it
smells so bad.

Some people want something else. The EPA recently
approved a new chemical – called Picaridin. It smells better.
Consumer Reports found that Picaridin products kept
mosquitoes away for up to four hours. That’s not too bad.

It’s better than the natural products. If you use soybean or
peppermint oil, Branden says you’ll probably have to reapply
a lot – at least every two hours.

“If you compare that to Picaridin product or the low DEET
products, that is not nearly the protection.”

Chemist Ulrich Burnier is on a team researching the next
generation of bug sprays. He believes there are more
effective chemicals out there. They’ve tested thousands of
chemicals and narrowed it down to seven.

“If we’re successful, the ideal product will give you 24 hours
protection, so you only have to apply once a day, you’ll be
protected around the clock. It’s not a plasticizer. And,
actually, this morning, I spent time trying to pick up odors
from these seven compounds, and none of us participating in this
study could detect any disagreeable odors from any of these
compounds.”

DEET still works pretty well. But mosquitoes and other
invading insects are thriving. As we experience climate
change, levels of mosquito-borne diseases like malaria are
on the rise.

(sound of baseball game)

When you’re at your nephew’s baseball game, and fending
off bugs, you might need to be a little patient. It could take a
few years. But experts say you should be able to find new
products that you like and that work for you.

Epa to Lift Termite Pesticide Ban?

The U.S. Environmental Protection Agency is considering extending the use of a
pesticide that
the agency once decided was not safe around children. The Great Lakes Radio
Consortium’s
Lester Graham reports:


The pesticide Dursban is sprayed on the ground during construction to protect new
homes from
termites. Four years ago, the EPA and Dow had agreed to phase out that use of the
pesticide by
the end of this year. Exposure to children was considered risky. Now, the EPA is
reportedly
considering lifting the ban. Jay Feldman heads up the environmental group Beyond
Pesticides.
Feldman says this would be like testing the safety of Dursban on humans without their
knowledge…


“They really should stop production, then stop use, do all the studies they want to
do with full
public disclosure and then revisit the issue. Not retain the use, allow people
unknowingly to be
exposed and then obviously put children at serious risk.”


In a report in The Washington Post, a Dow spokesperson indicated using new EPA
computer modeling, Dursban now “falls within an acceptable range” of federal
guidelines.


For the Great Lakes Radio Consortium, this is Lester Graham.
