Pesticides Linked to ADHD

Reuters writes that Pesticides tied to ADHD in children in U.S. study:
Researchers tracked the pesticides’ breakdown products in children’ urine and found those with high levels were almost twice as likely to develop ADHD as those with undetectable levels.

The findings are based on data from the general U.S. population, meaning that exposure to the pesticides could be harmful even at levels commonly found in children’s environment.

“There is growing concern that these pesticides may be related to ADHD,” said researcher Marc Weisskopf of the Harvard School of Public Health, who worked on the study.

“What this paper specifically highlights is that this may be true even at low concentrations.”

Organophosphates were originally developed for chemical warfare, and they are known to be toxic to the nervous system.

Then they try to greenwash the problem by saying to wash food before eating. Sure, that will help a bit, but many of the chemicals are inside the food, not just on it.

The problem is that by waging chemical warfare on weeds, we’re waging chemical warfare on ourselves.

Cover Crops to prevent erosion

Sarah Uttech writes that Cover crops reduce erosion, runoff:
Cover crops may be more effective at reducing soil erosion and runoff after maize harvest than rough tillage, according to scientists from the Université Catholique de Louvain, in collaboration with the Independent Center for the Promotion of Forage (CIPF).

The three-year study, supervised by Charles Bielders and conducted by Eric Laloy, measured erosion and runoff losses from silt loam and sandy loam soils in continuous silage maize cropping. The research revealed that cover crops reduced erosion by more than 94% compared to bare soil during the intercropping period. Cover crops and reduced tillage appeared equally effective in reducing runoff and soil loss between cropping cycles, despite the fact that the cover crop development was very poor.

The results were reported in the May/June 2010 edition of the Journal of Environmental Quality, a publication of the American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America.

This study was done in Belgium, but Tifton A soil we have around here is a sandy loamy soil. And as we know from research done in Georgia, around here we also need to manage the mutant pigweed, and for that a combination of plowing and winter cover crops works best.

HFCS and Cancer Tumors

It’s bad enough that High Fructose Corn Syrup (HFCS) makes you fat with resulting diabetes, high blood pressure, coronary artery disease, and cancer. Now Maggie Fox reports in Reuters that Cancer cells slurp up fructose, US study finds:
Aug 2 (Reuters) – Pancreatic tumor cells use fructose to divide and proliferate, U.S. researchers said on Monday in a study that challenges the common wisdom that all sugars are the same.

Tumor cells fed both glucose and fructose used the two sugars in two different ways, the team at the University of California Los Angeles found.

They said their finding, published in the journal Cancer Research, may help explain other studies that have linked fructose intake with pancreatic cancer, one of the deadliest cancer types.

“These findings show that cancer cells can readily metabolize fructose to increase proliferation,” Dr. Anthony Heaney of UCLA’s Jonsson Cancer Center and colleagues wrote.

“They have major significance for cancer patients given dietary refined fructose consumption, and indicate that efforts to reduce refined fructose intake or inhibit fructose-mediated actions may disrupt cancer growth.”

Americans take in large amounts of fructose, mainly in high fructose corn syrup, a mix of fructose and glucose that is used in soft drinks, bread and a range of other foods.

2,4-D: Back to the Past

So, having just spent a decade breeding mutant superweeds by pouuring pesticides on crops, what’s the recommended future of weed science?

Pour pesticides on crops until they breed more mutant superweeds.

So what is our old friend 2,4-D, which used to be commonly used back in the 1980s? Continue reading →

Managing the Seedbank by Plowing

Roundup has bred quite a few mutant weeds, such as marestail and ragweed that haven’t yet made it to Georgia. But the king of mutant superweeds everywhere is Palmer Amaranth: pigweed.

About pigweed, Georgia Extension weed scientist Dr. Stanley Culpepper says:

Economic survival will depend on managing the seedbank!!!!
That’s on page 30 of a 46 page presentation at the 2010 Beltwide – Consultants Conference, after discussing how rapidly Roundup-Ready seeds have been adopted:

And how the value of advice on weed control during that period rapidly decreased as a direct correlation: Continue reading →

Pigweed: don’t let it come up

So is it just a few people’s opinion that plowing works much better than herbicides to control mutant pigweed?

Henry Gantz writes in Don’t Give Pigweed The Light Of Day, If it doesn’t come up, you don’t have to kill it that farmers were depending mostly on Roundup, but that no longer works, due to multiple mutant weeds, including pigweed and marestail. He quotes Dr. Larry Steckle, Extension weed specialist at the University of Tennessee:

Steckle said we’ve now reached the point where we have to begin thinking in terms of controlling “resistant weeds” instead of “resistant marestail” or “resistant Palmer pigweed” because they are both beginning to show up in the same field.

“We have to manage them both,” he said. “There’s a new product from BASF called Sharpen that I’ve been looking at for five years and I’ve been very impressed with the marestail control. I still like dicamba, Roundup and Gramoxone.

“But if you have Palmer pigweed, too, then you’re going to have to overlap with residuals ― Cotoran, Caparol, Prowl ― to have any chance to do a good job of controlling them.”

So, what’s the solution: Continue reading →

Deep-Till: Back to the Future of Plowing

Roy Roberson writes in Farm Press about http://southeastfarmpress.com/cotton/herbicide-resistance-0525/:
Deep tilling of crop land pocked and rutted by heavy equipment used on rain and snow soaked, often frozen farm land may not only clean up the land, but may have a significant positive effect on managing herbicide resistant weeds, especially Palmer pigweed.
Back to the future! “Deep tilling” is the current buzzword for plowing. That’s how my father farmed, with a bottom plow, a subsoiler, a harrow, and a cultivator.

The same article continues to defend no-till:

There is no doubt about the many benefits of minimum or no-till cropping systems. Reduced-tillage saves farmers money in equipment, improves soil quality, improves the environment by making the soil more porous and produces better drainage. The list of benefits goes on and on.
Promotes more erosion, is my observation. And how does no-till save farmers money if they have to pay for increasing amounts of pesticides to try to deal with mutant weeds like pigweed? Continue reading →

Local food for sustainability

James Polk provides us some Food for Thought:
Let’s take a quick tally. 1) Locally grown food uses less fossil fuel getting to market, 2) fresh fruits and vegetables are healthier than packaged foods, and 3) buying locally grown food supports your local economy possibly keeping your would-be deadbeat friends employed.

My favorite reason to eat locally grown foods is the taste. Go to a farmers’ market and load up on freshly picked tomatoes, bite into a raw crisp green bean, take home some succulent zuccinni and eggplant to stir-fry – you’ll be hard-pressed to find a more delicious meal.

Yep. That and okra. Anybody need some okra?

Monsanto Fined $2.5 Million

Jimmy Mengel EPA Slaps Monsanto with Record Fine, Million Dollar Settlement the Largest in Series of Penalties:
The agricultural giant was found to have been selling genetically modified cotton seeds without labeling them as such. Between 2002 and 2007, Monsanto’s seeds were illegally sold in several Texas counties where the seeds are explicitly banned.

The seeds — known as Bollgard and Bollgard II — were genetically engineered to produce the insecticide Bacillus thuringiensis (Bt), and Texas officials were concerned that using the seeds would lead to pest resistance.

But that didn’t stop Monsanto from bamboozling buyers into purchasing the illegal seeds.

Here’s the bad news: Monsanto’s market cap is $29.5 billion, so the fine is less than a hundredth of a percent of that.

Still, the fines keep going up. Maybe eventually they’ll get big enough to sting.

Or we could just trust the company that made Agent Orange and DDT.

Or we could remember this: Continue reading →
