Pesticides and Unintended Consequences

Pesticide DriftWe’ve already mentioned the fine documentary released early this summer More Than Honey, a film that looks at the behavior of bees as well as issues and consequences behind colony collapse disorder that’s sweeping the world. As the movie states, bee activity is responsible for a third of the food we eat. Losing them would have impacts well beyond the loss of some fruit. It could mean a complete change in the way we live. The movie shows us an example of a place where bees have already vanished and the consequences that followed.

The place is China. Seems that Mao Tzedog before his death in 1976 decided that a plague of sparrows was putting a large dent in grain production. So in the kind of short-sighted, ill-conceived wisdom that’s apparently shared by Chinese dictators and American corporate agricultural CEOs, Mao called for the elimination of sparrows. The killing of the sparrows released a swarm of insects, a problem that affected agriculture much more than the damage done by the birds. So massive spraying programs were instituted. The spraying not only killed harmful insects, it killed beneficial ones as well, including pollinators. Without bees, Chinese crops blossomed but didn’t produce. The solution? Hand pollination.

Tomato Patrol

Tomato WormA friend, an avid organic tomato grower, has started her harvest and you know what that means. Tomato Festival! The festival usually runs from the first weeks of August right up to the first frost (at which point it becomes Green Tomato Festival or the Wait-Until-These-Tomatoes-In-the-Windowsill- Ripen Fest).

The event, held in kitchens around the country, is an unofficial celebration of one of our most cherished home-gardening products. Our friend grows heirlooms and so far this year has a bounty crop of golden jubilee, a juicy, subtly flavored orange tomato, as well as big, bold brandywines, and a few unusual, tremendously sweet, strangely colored chocolate stripes.

Bees Swarm Media

Honeybee ColonyIs it still possible to take bees for granted? Since the general population learned about colony collapse disorder, the mysterious effect that has destroyed a large percentage of the world’s pollinators in a 2007 broadcast of CBS’s 60 Minutes and the publicity in its wake, people have come to appreciate bees for the critical work they do. Before, when someone was asked to think of the first word that comes to mind when they hear “bee,” they might have said “sting” or “honey.” Now they just might say “food” or “survival.”

That’s our survival, not just theirs.

Honeybees are critical to the food supply. Like tomatoes, cucumbers, blueberries, squash, almonds, and melons of all types? Thank the bees. It’s estimated that of the 100 food crops grown around the world, crops that supply 90% of the world’s food, bees pollinate 70 of them. Without bees, there would be no watermelons, no blueberry cobbler, no marinara. It’s estimated that bees, acting as pollinators, add $15 billion a year to food production. (more…)

Managing Pests In the Organic Garden

Spraying PesticidesNo matter how carefully you control growing conditions with healthy soil and proper watering, no matter how well-thought out your integrated pest management system, no matter how lucky you’ve been in the past, sometimes a pest problem arises in your garden that requires spraying the little buggers. What you spray and how you spray can make all the difference.

Most organic gardeners prefer sprays that break down quickly in the environment or opt for home made remedies that make the plant unpalatable or difficult for the insects to populate. These sprays are often made of garlic, cayenne and other peppers, as well as strong scented herbs. The idea is to confuse the insect’s sense of smell (which is often located in their feet) and make them think they are where they don’t want to be. They’re often the organic gardeners first line of defense when pests are spotted.

The second line? Citrus oils, diatomaceous earth, even compost tea are known to work on some insects. Then there are the manufactured products you can make at home that suffocate the pest or make their environment inhospitable. These include soap solutions, often made at home and horticultural oils. Then there are other solutions including those with baking soda, alcohol, and ammonia. Boric acid is a well-known deterrent for migrating insects, one that acts as a stomach poison. Bleach is used especially in greenhouses to disinfect and control diseases. These ingredients are toxic unless diluted and dangerous if not handled correctly. (more…)

Weeds vs Herbicides: Weeds Win!

Applying HerbicidesAn article in The New York Times seems to celebrate weeds: their hardiness, their adaptability, their ability to quickly evolve. It’s overall theme? In the battle between weeds and chemical herbicides, weeds eventually and always win. And while it takes some reading between the lines, the article also draws conclusions that organic gardeners have known all along. One… herbicides can be dangerous. Two… a variety of techniques, many of them organic, are needed to actually reduce crop losses caused by weeds.

So why use herbicides? Their development (PDF format) was thought to be a tremendous breakthrough. As far back as Roman times farmers spread salt on their fields to destroy their enemies’ crops. Modern weed killers were introduced during World War II and their use skyrocketed after that. Chemical companies soon learned that herbicides meant big money. But almost as quickly, weeds began to develop resistance to the chemicals. Today, it’s estimated that at least 217 varieties of weeds have developed resistance (follow the link to see a frightening photo of giant ragweed taking over a field of Roundup resistant corn).

Avoiding (And Treating) Melon Problems

Garden MelonsAfter our last column, a friend pointed out that she didn’t have trouble getting melons to pollinate. Her problem was with blights and mildew. It’s true that melons are a bit difficult to grow because of their susceptibility to molds and certain insects, especially when you’re trying to grow them in cooler, damp climates. Any trouble growing melons is well worth it once they reach the table. The cantaloupes, watermelons and other melons now coming into our stores from warmer climates just don’t hold a candle to a juicy, sweet, homegrown melon.

Finding the proper natural or organic cures for these melon problems can be difficult. Mulching is great for issues caused by uneven watering. But mulch can provide places for pests including squash bugs and cucumber beetles to lay eggs. These pesky critters not only consume melon plants but spread disease and wilt. Melon leaves can be burned by insecticidal soap and liquid copper sprays, two common, organic-approved solutions for bugs and mildew. They should only be used in the most diluted form possible. Other problem solvers — like using row covers to shield plants from insects — are great ideas until you need the help of pollinators. Any successful melon growing regimen begins even before you start them in your garden. (more…)

Ladybugs To the Rescue

LadybugAmerica’s largest shopping mall, The Mall of America, in Bloomington, Minnesota, is as well known for its attractions — an indoor amusement park! an eco-park! — as it is for its collection of retail stores. It also has some 30,000 plants and 400 live trees, some as tall as 35 feet, growing inside its spacious confines. So how do they prevent an infestation of harmful insects? You don’t want to spray and endanger the 40 million visitors the Mall sees each year.

What do they do at the mall? Take a hint from greenhouses around the country and release ladybugs (also known as lady beetles). The mall recently unleashed 72,000 of the hungry critters to help control aphids and other pests. Fears that they might go after the treats shoppers carry around or enjoy in the food courts are unfounded. The bugs stick almost exclusively to plants and are only interested in getting their meals on the hoof (so to speak). Even in a space as large as the mall — it’s claimed that seven Yankee Stadiums would fit inside — the ladybugs are confined. If they finish the pests in one area and move on looking for more prey, they’ll still be inside the mall. (more…)

News: GMOs, Bees and Politics

Monsanto Protection ActEnough Fault To Go Around: It’s been pointed out that the “Farmers Assurance Provision,” popularly known as the Monsanto Protection Act, was signed by President Obama into law last Tuesday. This hasn’t earned the President any fans among those resisting the use of GMOs in our foods.

As some have pointed out, the bill was mostly about the continuing budget resolution to keep the government afloat and included the Violence Against Women Act and State Nutritional Assistance Program (though neither of those was kept secret and anonymously offered as was the Monsanto Protection Act). Your politically frustrated Planet Natural Blogger — I’m sure I have a lot of company here — thinks that riders of this type should stand alone, that attaching them to budget bills is a hoodwink and/or form of blackmail. Protect Monsanto or the whole country goes down! Shame on us all. (more…)

Bird Decline Linked to Toxic Pesticides

Song BirdIt’s no secret. For years, we’ve known that bird species in America’s farmlands and grasslands have been in steep decline. The assumption was that this was due to habitat removal caused by agricultural expansion and the spread of cities into land once devoted to farming. Now a new study from Canada not only confirms the bird decline but challenges the commonly held wisdom. What’s doing away with all those birds? Pesticides.

News sources both large and small have called attention to the study. You can read it here (PDF format). A 2009 interview with the study’s leader, Dr. Pierre Mineau, can be found here. Take away quote: “What I find really shocking is when a company does studies that show significant impacts and then continues to market the pesticide around the world. Take granular carbofuran. The first time they did the tests for the EPA they found 799 dead birds of a single species (a lark) in a few fields. Other species were affected also but not in such numbers. Nevertheless, it took about 15 years for that product to be removed from North America – it continues to be used worldwide.” (more…)

Controlling Insect Pests With Birds

Bird and Garden InsectI’m recalling one of the great sights of spring gardening this cold February night: working the soil for the first time and having birds descend to pick out the slow moving grubs that had been hiding under the earth. Sure, the birds got a valuable earthworm or two, but not so many that it would dent the population. Those worms began to tunnel back almost as soon as daylight hit them. And many were still buried deep — very deep — where my turning fork couldn’t yet reach them. But those grubs, twisting and turning on top of the freshly spaded clods. They made for easy pickings.

Of course, that got me thinking about watching birds work the garden in the summer, feasting on insects, caterpillars, and whatever else they can find. (more…)
