New invasive insect could threaten peaches

Clemson University officials are asking for the public’s help in tracking a new invasive insect that has begun appearing in South Carolina. Called the brown marmoset stinkbug, it can cause major infestations in houses, releasing a strong odor as it does so. It also threatens fruit trees, worrying many peach farmers in the state.

The stinkbug was first identified in Pennsylvania in 1998. It has spread through the Mid-Atlantic and South over the past ten years. Although it has some predators– such as snakes, lizards, and spiders– there are not enough to keep the population in check. Its primary predator in Asia is a species of parasitic wasp that does not exist in the United States.

The bug is mostly brown, but has a black and white checkerboard pattern around the edge of its body. Other than that border, it resembles the native brown stinkbug. However, there is one big difference: the Asian bugs gather in large groups, often causing an infestation.

“Basically, they like to hang out in large numbers together,” Sherry Aultman, the Cooperative Agricultural Pest Survey coordinator with Clemson’s plant industry department, said. “Part of the chemical smell they emit is actually signal saying ‘Hey, guys, come over here. I found something really good.’”

Groups want to end modified crops in Santee wildlife refuge

Three environmental groups have filed a lawsuit trying to stop the planting of genetically-modified crops at wildlife refuges in the Southeast, including one location in South Carolina. The lawsuit covers 25 refuges across the Southeast that plant the crops.

Right now, Santee National Wildlife Refuge on Lake Marion allows farmers to grow corn on roughly 175 acres, with much of it meant to feed ducks and geese that pass through the park. The Fish & Wildlife Service, the agency that runs the nation’s wildlife refuges, does not make money off its arrangement with farmers.

However, the Center for Food Safety says it is concerned about the effects of that farming and is suing to stop the practice. ”These crops promote overuse of herbicides,” staff attorney Paige Tomaselli said, ”Since most genetically-modified crops are herbicide-tolerant, the farmers can indiscriminately douse the crops with as much herbicide as they want… And this can affect wildlife, biodiversity, and humans who visit the refuge.”

The lawsuit demands an end to the practice until the Fish & Wildlife Service completes an environmental impact statement. However, Fish & Wildlife spokesman Tom MacKenzie said the agency already goes beyond the restrictions for traditional farms: allowing fewer pesticides, creating “buffers” between the crops and waterways, and requiring farmers to rotate crops.

“We’ve been in the cooperative farm business for years and we’ve utilized genetically-modified crops just like most of the other farmers in America are doing,” MacKenzie said.

Santee NWR was created in 1941 to provide a haven for waterfowl after the Santee River was dammed to create Lake Marion. Farming is relatively small there, but officials work with farmers to plant millet and sorghum, with 25 percent of the crop reserved for migrating waterfowl, such as geese and ducks. After a harvest, the field is flooded, and the leftover grain provides a source of food for the birds.

However, Tomaselli disputes that the crops provide extra food. “These crops are pushing out the native grasses that were originally there to feed the migratory birds,” she said, “As long as we’re perpetuating the farming on the refuges, the native grasses and other plants cannot return.”

Santee Refuge Manager Marc Epstein said the number of waterfowl has recently started to decline at the site. He said the crops offer a way to maintain the population. However, the rising costs of fertilizer, fuel, and seeds are slowing farmers down, “It’s costly for us to do these programs,” he said.

Tomaselli says, while the group is pushing to stop the planting of genetically modified crops, it wants to eventually stop any type of farming in wildlife refuges. The group has successfully stopped the practice in the Northeast after two lawsuits in Delaware, and is now looking at ending farming in the Southeast, as well.

MacKenzie said that would have a negative impact, “For 25 out of our 128 refuges, we currently believe that farming helps wildlife.”

The complaint was filed in a federal court in Washington, D.C. Two other environmental groups, Public Employees for Environmental Responsibility and Beyond Pesticides, are also involved in the lawsuit.

Mexico is now open for South Carolina peaches

For the first time in nearly two decades, South Carolina peaches are being sold in Mexico. Titan Farms, based in the town of Ridge Spring, became the first company to take advantage of a new agreement between Mexico and the United States.

The new deal sets strict rules about how the fruit must be grown. The reason is because Mexico banned southern peaches in 1994 due to concerns about invasive pests. After that, only California peaches were imported into the country.

Titan Farms President and CEO Chalmers Carr III said the new agreement is big for his company, “When you look at the domestic supply of peaches, there has been… an oversupply in the amount of peaches produced that are being consumed in the United States,” he said, “Broadening your market base for any agricultural commodity is important.”

A few years ago, farmers from Georgia and South Carolina began reaching out to the Department of Agriculture to ask why they could not export peaches to Mexico. In 2007, the U.S. Department of Agriculture (USDA) began testing Southern plants to check for pests and determine if there was any risk those pests could appear. Such standards are necessary under the North American Free Trade Agreement (NAFTA).

The process went slowly for three years, as required. However, Chalmers said Mexico became spooked by the appearance of new invasive bugs in California peaches last year. “That put Mexico on ‘red alert,’” Carr said, “Even though those pests were not in the Southeast at all… we were penalized for that situation.”

Carr said the process became bogged down until he was finally able to contact a USDA official stationed in Mexico, who set up a meeting with Mexican officials. The CEO said he made the trip to the country himself to represent the industry in April (government officials are not allowed to do the negotiations). “That’s what really finally moved the ball,” he said.

Clemson University peach specialist Desmond Layne, known to farmers as “Doctor Peach,” said Mexico presents an opportunity for growers to sell fruit that might not make supermarket shelves.

“The Mexican market prefers the smaller-sized peaches, so that’s sort of a double bonus” Layne said, “They want the fruit that, for us, maybe doesn’t earn as much money in our market because of its smaller size.”

Titan, the state’s largest peach producer at 4,900 acres, is also the only one in Georgia or South Carolina currently shipping to Mexico. Carr said that’s because of the hard requirements Mexico puts in place– setting and trapping pests, frequent inspections in the field, and keeping the fruit separate from peaches bound for other locations. Carr said those standards resulted in smaller farms backing out this year.

However, he predicted more companies would be able to take advantage of the new agreement in the future. There is a second possible avenue for those wanting to expand– a fumigation approach. Carr said that requires a USDA-approved facility which does not currently exist in the Southeast. He predicted one would be built before the end of the year.

Another hurdle is shipping the peaches nearly 3,000 miles to Mexico. Peaches are a delicate fruit that have to be handled carefully. For instance, they must be transported at a temperature below 35 degrees to avoid ripening. Since peaches also bruise easily, trucks carrying them must be equipped with air bags to lessen the effect of any bumps in the road on the cargo. Producers are also using special pallets that use corner posts to stabilize the load and prevent it from swaying. Such methods are traditionally used with other higher-value fruit, such as cherries.

“To get peaches a long distance in good quality is very expensive,” Layne said. He said it costs almost $9,000 for tractor-trailer truck to carry peaches from coast-to-coast in the United States, “That’s just the cost of moving the fruit. That’s not the cost that’s in the fruit in terms of growing it, packing it, and everything else.”

The Mexican retailer selling the peaches is responsible for transporting them to the country.

New hunting law soon goes into effect

Rep. Bill Hixon (R-North Augusta)

State Representative Bill Hixon (R-North Augusta) had it easy on his first piece of legislation.

The freshman lawmaker and avid hunter first arrived at the Statehouse in January after his election last year. He immediately worked to shepherd a little-noticed bill through the legislature that has major implications for hunters in South Carolina.

The quiet Aiken County legislator will get a moment in the spotlight Tuesday as Governor Nikki Haley plans to hold a ceremonial signing of the law in his hometown of North Augusta. The new law lets South Carolina join the Interstate Wildlife Violator Compact– a hunting agreement between 44 states. While it may not sound like much, it actually fixes what Hixon and wildlife management officials say was a major hole in state game laws.

Right now, if a person from outside South Carolina commits a hunting or fishing violation in the state, the game warden is required to collect a fine on the spot, and take the hunter to prison if they are unable to pay it. Likewise for South Carolinians in many other states. Without being in the compact, a South Carolina hunting license is no good across state lines, and is akin to hunting or fishing with no license at all.

Hixon said most wardens believed the law was an unnecessary burden, and would instead take out-of-state violators to ATMs or escort them home so they could get money to pay the fines. He said he was afraid some hunters who could not pay were going to jail unnecessarily, “I think it would be a shame to see somebody’s (mug shot) that caught too many fish or did not have enough life jackets, or something like that,” Hixon said, “Jail needs to be a place for hardened criminals.”

He said he was surprised when he arrived in Columbia and no one could tell him why South Carolina was not participating in the compact. “I would try to tell these House members and senators about this,” Hixon said, “Every one of them would look at me and say, ‘Why haven’t we done this before?’ And I would say, ‘I don’t know… I just got here. I was just elected.”

The new law, originally passed by the legislature and signed by the governor in April, would address that problem by enrolling South Carolina in the compact. Under the agreement, a South Carolina hunting license would be recognized as valid in other states, much like a driver’s license.

South Carolina would also have access to a national database that allows Department of Natural Resources officials to do background checks on new hunters to see if their license was suspended in another state. Right now, officials have no way to get to that database.

It’s unusual for a freshman legislator to get a law changed in his first year, especially one that passes overwhelmingly, as Hixon’s bill did. “It was a dream come true for a first piece of legislation as a freshman,” Hixon said. “I was proud to do it.”

The law will go into effect within the next six months, as DNR begins the process of implementing the changes.

New farmer’s market part of health research

The Right Choice Fresh Start Farmers' Market to increase access to fresh fruits and vegetables as part of research.

The state’s first farmers market located at a federally qualified health center is now open in Orangeburg. 

The Right Choice Fresh Start Farmers’ Market is designed to increase access to fresh fruits and vegetables to medically underserved patients. The market is supported by a Centers for Disease Control and Prevention grant to the University of South Carolina’s Cancer Prevention and Control Research Network. It is part of the national cancer prevention and control research network, one of 10 projects nationally.

The center held a grand opening ceremony Friday.

University of South Carolina social work professor Darcy Freedman led the effort to create the market. Freedman said the goal is to increase access to healthy food options for people in rural communities and to link health promotion and economic development.

Researchers are also examining the influence of the market on patients at the health center, including how, or if, it influences their diet. They are specifically tracking patients with diabetes, as well as are looking at the economic impact of the market on farmers.
