Citrus Greening Solutions

$3.3 billion. That’s what the National Agricultural Statistics Service rates the value of the citrus industry in the United States. Yet danger and some of the industry’s greatest challenges lurk in citrus groves across the country — devastating pests and diseases.

The Department of Homeland Security estimates invasive species annually cause $136 billion in overall lost agricultural revenue in the United States.

The Asian citrus psyllid, which creates a disease-causing bacteria known as Huanglongbing (HLB) or citrus greening, is one of the citrus industry’s most destructive insects. It has infected commercial and residential citrus trees across the country from Florida to Texas to California. The disease clogs an infected tree’s vascular system, preventing fruit from maturing and eventually killing the tree.

First identified in China in 1919, by 1937 it had spread to the Philippines and South Africa. Continue Reading →

Poisoning Our Children: Pesticide Residues

In December 2014, the United States Department of Agriculture (USDA) sent out a news release to all the media outlets in the country about the results of its 2013 Pesticide Data Program (PDP). The headline: “Report confirms that U.S. food does not pose a safety concern based on pesticide residues.”

Because people consume a variety of foods, with around 77 percent containing residues of different types of agricultural chemicals, most people consume a chemical concoction.

The news release contained the following statement from the United States Environmental Protection Agency (EPA): “The newest data from the PDP confirm that pesticide residues in food do not pose a safety concern for Americans. EPA remains committed to a rigorous, science-based, and transparent regulatory program for pesticides that continues to protect people’s health and the environment.” So according to the EPA and the USDA, parents should have no concerns because the pesticides in food are safe.

Hundreds of peer-reviewed scientific papers by scientists and researchers challenge this assertion. So, let’s look at the science to understand why experts have serious concerns about the safety of pesticides.

What Gets Tested?

One of the greatest pesticide myths is that all agricultural poisons are scientifically tested to ensure that they are used safely. According to the United States President’s Cancer Panel (USPCP), this is simply not the case: “Only a few hundred of the more than 80,000 chemicals in use in the United States have been tested for safety.”

The fact is that the overwhelming majority of chemicals used worldwide have not been subjected to testing. Given that, according to the USPCP, the majority of cancers are caused by environmental exposures, especially exposure to chemicals, this oversight shows a serious level of neglect by regulatory authorities.

Farmer Health: Personal Pathway to Healing

A few years ago I spent a cold weekend in November harvesting around 60 fully grown turkeys that each weighed approximately 30-45 pounds or so. They all had to be slaughtered, plucked, gutted, cleaned and bagged, and I used and abused my right arm and shoulder that day. At the end of that long and gory day I remember losing some feeling in the fingertips of my right arm. The next morning I woke up with a shoulder that was so inflamed and painful that I was more or less incapacitated for the day. Even when I tried to lay down and rest, the pain in my shoulder was so intense that I couldn’t stay still for more than a couple of seconds.

Dr. Kellie Seth at her practice, Healing River Chiropractic, in Stillwater, Minnesota.

Instead of sleeping I tossed and turned for a few nights. With my shoulder pain unabating, I called Dr. Kellie Seth on the recommendation of friends and made an appointment to see her. I remember pleading with her jokingly, asking her to help me be able to sleep again. In the meantime, I started to pop ibuprofen like candy.

When the appointment time came, I drove my truck, which had a manual transmission, to her office in Stillwater. Even just sitting on the driver’s seat caused agonizing pain in my shoulder. Finally, I got to her office after much gritting of my teeth.

It was difficult for me to even get my T-shirt off over my head and to set my keys and phone down. Kellie had me sit down on her chiropractic table and worked on my shoulder with a variety of methods, adjusting my neck and back. After a while she asked me how I felt. The pain was relieved tremendously. She informed me that I probably had a torn rotator cuff, and I would have to rest for a few weeks, preferably months, in order to let my shoulder heal. As a farmer, that was easier said than done.

As I drove home I realized that I hadn’t been feeling pain in my shoulder as I sat. When I arrived back on the farm, I also realized that I was able to use my arm again with very little pain. In the following days my shoulder began to feel normal again. Continue Reading →

Managing Parasites in Livestock

Internal parasites are part and parcel of the animal’s ecosystem, or its “body ecology.” Wild ungulates are continually moving, leaving their parasite loads behind where they desiccate in the sun or just plain run out of nourishment before the animals return to the pasture. However, animals that are subjected to pasture or loafing areas without adequate rest will build up parasite loads, especially on humid landscapes, where moisture and temperature are conducive to their growth and reproductive cycles.

Young animals and those with weakened immune systems are most vulnerable, and this includes pregnant and lactating animals. Never allow your stock with parasite challenges to become underweight.

Parasites: Landscape Management

The first and most important component in parasite management is landscape management by employing sound rotation practices. This includes not only the adequate amount of time for the rest period between rotational grazing, but also grazing height management.

Natural Weed Control

There are many ways for growers to implement non-toxic weed control methods on their farms. The most obvious is to take the chemical farming approach and find an organically-approved material to do the killing. Very strong vinegar has been the most marketed material. The important factor in vinegar formulas is to include a surfactant to strip away any waxy protective coating on the plant surface to allow the desiccation (drying out) of the plant. Salt provides the same mode of action and may be included in the formula.

Natural weed control

The primary condition that promotes broadleaf weeds is the ratio of available phosphorus to available potassium, as shown by a LaMotte soil test. The further you deviate from a 1:1 ratio, the stronger the broadleaf pressure.

Other modern mechanical approaches to weed control include flaming, cultivating, and smothering. Cultivators are a modern version of hoeing or hand pulling. Rotary hoes or spiked harrows are special adaptations of the cultivation approach. Using plastic films, whether biodegradable or not, is a form of smothering that is similar to mulching with any material. The cover denies sunlight to prevent growth.

Repeated cuttings of a perennial weed in a fallow field may weaken a plant over time by using up its stored energy. Farmers should also make every attempt to prevent the reseeding of an offending species. Treating isolated patches is worth the effort to keep them from spreading. If a field is overwhelmed to a point of not having an economic crop worth harvesting, be sure to take the whole field down before the weeds go to seed. Keep in mind that there are seeds in your fields that may have been there for years. Just lime or activate the calcium in your soil and watch clover appear in uncultivated ground, even if you haven’t seeded it since you bought the farm.

Glyphosate: A Toxic Legacy

Journalist and Author Carey Gillam Shares Decades of Research into Monsanto and its Ubiquitous Weed Killer

Carey Gillam discusses glyphosateCarey Gillam is a Kansas-based journalist turned glyphosate geek. Her first book, Whitewash: The Story of a Weed Killer, Cancer, and the Corruption of Science, fills a gaping hole in the literature and is getting excellent reviews. Erin Brockovich says Whitewash “reads like a mystery novel as Gillam skillfully uncovers Monsanto’s secretive strategies.” Publishers Weekly says, “Gillam expertly covers a contentious front” and paints “a damning picture.” And Booklist calls it “a must-read.” Gillam brings more than 25 years in the news industry covering corporate America to her project investigating Monsanto’s premier product and the malfeasance that surrounds it. During her 17 years employed by the global news service Reuters she developed her specialty in the big business of food and agriculture. Besides covering topics like economic policy, corporate earnings and commodities trading, she was pulled away to write about presidential politics, natural disasters and a range of other general news and feature topics. Two years ago she became Research Director
 with U.S. Right to Know, a nonprofit consumer group that pursues truth and transparency in America’s food industry. Gillam says she always knew she “wanted to be a journalist, to build a career on the simple pursuit of truth. My work is based on the belief that by sharing information and ideas, airing debates, and unveiling actions and events critical to public policy, we help advance and strengthen our community — our humanity.”
