    Recent Rain Affecting Your Garden? Here Are Tips to Help You Weather the Storm

    SPRINGFIELD, Ohio — Recent storms and flooding in most parts of Ohio have taken a toll not just on field crops but also on backyard gardens and landscapes. Pam Bennett, horticulture educator with the College of Food, Agricultural, and Environmental Sciences at The Ohio State University, said wet conditions can lead to three main concerns for gardens: root death, diseases and weeds. “Hopefully by now, the water has drained. If not, you may have some trouble with your plants,” said Bennett, who is also the state Master Gardener Volunteer coordinator for Ohio State University Extension, the college’s outreach arm. “Plant roots need oxygen; they need that air in order to grow. When they sit in water for a period of time, that leads to root rot and lack of...

    4-H Fair Bird Exhibits Cancelled in Ohio to Protect Industry from Avian Flu

    COLUMBUS, Ohio — Ohio 4-H is expressing support of the Ohio Department of Agriculture’s decision to cancel all live bird exhibitions at county and independent fairs in 2015 to protect Ohio’s $2.3 billion poultry industry from the current avian flu outbreak affecting the United States. The cancellation, announced today (June 2) by Agriculture Director David T. Daniels, covers poultry and waterfowl exhibits and also extends to the Ohio State Fair and all other gatherings of birds for show or for sale, including auctions and swap meets. “We appreciate Director Daniels’ leadership in protecting Ohio’s poultry industry,” said Bruce McPheron, vice president for agricultural administration and dean of the College of Food, Agricultural, and...

    Hanging Baskets: How to Select, Keep Them Alive Longer

    WOOSTER, Ohio — Hanging baskets are a great choice to decorate porches, decks and patios with color and fragrance. They are also a good gardening alternative for people with small spaces or who prefer not to go the flower bed route. To make the most out of your hanging baskets this season, it’s important that you select the right plants for your home and that you take proper care of them, said Bob McMahon, associate professor and coordinator of the greenhouse and nursery management program at The Ohio State University Agricultural Technical Institute (ATI), the associate’s degree-granting school of the university’s College of Food, Agricultural, and Environmental Sciences. “Hanging baskets take three to four months to grow to marketable size. They take a...

    ‘All Corn Is the Same,’ and Other Foolishness about America’s King of Crops

    COLUMBUS, Ohio — In 2014, farmers across the United States harvested 14.2 billion bushels of corn from 83.1 million acres, for a total value of $51.9 billion. Everything about corn is big in the United States. Corn is the No. 1 crop grown in the country, while America leads the world in production and consumption of this vital grain, according to data from the U.S. Department of Agriculture. Grown by Native Americans well before the arrival of Europeans, corn has been part of the agricultural landscape, food traditions and culture of what is now the United States for millennia. Despite its enormous influence and popularity, there are many things you may not know about corn — and others you think you know but are, in fact, incorrect. Here are some facts and myths about the...

    A Diploma and a Job: Ohio State ATI Programs Put You on Path to Success

    WOOSTER, Ohio — In 2012, Cody Bower enrolled in the very first class of the renewable energy program at The Ohio State University Agricultural Technical Institute (ATI). One year later, he had full-time employment in his field of study. “After my first year, I enrolled in a summer internship through Ohio State ATI at the city of Wooster’s Water Pollution Control Plant,” said Bower, a graduate of Northwestern High School in Wayne County, Ohio.  “I was taught various laboratory procedures, and part way through that summer, I was offered a full-time position as an assistant operator. It was very amazing to be gainfully employed by my 20th birthday because of the opportunities granted to me by the renewable energy program.” In the coming fall, Bower...

    12 Days of Experts: A Piglet Killer on the Loose: Is Holiday Pork in Peril?

    COLUMBUS, Ohio — Pork is in shorter supply and more expensive this year due to a disease that has slashed the number of hogs slaughtered by about 5 percent and reduced the availability of the most popular holiday pork product: the seven-pound spiral-cut half ham. Porcine epidemic diarrhea virus (PEDv) was first found in the U.S. in 2013 and has killed millions of piglets since, impacting the number of hogs reaching market, said Steve Moeller, a swine specialist with Ohio State University’s College of Food, Agricultural, and Environmental Sciences. A member of the coronavirus family, PEDv causes intestinal disease in swine of all ages and high mortality in young pigs — especially among pre-weaned pigs, for which mortality is almost 100 percent. The...

    12 Days of Experts: How to Choose and Care for your Poinsettia

    WOOSTER, Ohio — Poinsettias are America’s favorite Christmas ornamental plant. Whether you prefer traditional red, white, pink or any of the marbled and speckled varieties now available, you want to make sure you select the right poinsettia and take the proper care so it can thrive during the holidays and beyond. “When you go to the store, inspect the plants carefully and make sure that you don’t see leaves that are dried out, that are sagging, that have obvious signs of damage,” said Luis Cañas, an entomologist and expert on greenhouse ornamentals with Ohio State University’s College of Food, Agricultural, and Environmental Sciences. “Then approach the plant, gently turn the leaves and take a look at the underside of the leaves, which is...

    Open Food Trade, Safety Nets Crucial to Global Food Security: Ohio State Economist

    COLUMBUS, Ohio – After a months-long stalemate, the United States and India reached a deal Nov. 13 that would revive World Trade Organization negotiations and help push global customs reforms expected to add $1 trillion and 21 million jobs to the world economy, according to figures from the International Chamber of Commerce. The key issue behind the dispute: India’s stockpiling of food to ensure its 1.25 billion inhabitants have enough to eat. Under the deal, India agreed to withdraw its veto of WTO reforms but asserted its right to stockpile food without observing the trade body’s usual rules on agricultural subsidies. Ian Sheldon, an international trade expert with Ohio State University’s College of Food, Agricultural, and Environmental Sciences, said India...

    Sharing Knowledge in the Developing World: Ohio State Scientist Helps Fight Plant Diseases, Poverty

    WOOSTER, Ohio – If knowledge truly is power, Ohio State University plant pathologist Sally Miller believes that sharing knowledge can help alleviate one of the most pressing issues facing millions of people in the developing world: being able to grow enough food to eat and make a living. Miller most recently traveled to the West African nation of Senegal, where she taught at an international workshop on invasive species identification and management in the tropics, May 12-15, in the capital city of Dakar. In Senegal, which is roughly the size of Nebraska, droughts are common and soils are poor, Miller said. Despite these adverse conditions, more than 60 percent of the country’s 13 million people, as in most developing countries, make their living by farming. “We know...

    Will It Live or Die? Researchers Develop Biomarkers to Manage Impact of Sudden Oak Death

    COLUMBUS, Ohio -- Ohio State University researchers have developed a way to predict the resistance or susceptibility of trees to sudden oak death disease, providing forest managers with the first effective method to manage trees in infested natural areas and in adjoining areas where the disease is expected in the future. A forest disease caused by the invasive fungus-like pathogen Phytophthora ramorum, sudden oak death was first detected in California in 1995. It has since killed millions of tanoaks and trees of several oak species on the West Coast. It is also a potential threat to the valuable Eastern oak species, some of which are known to be highly susceptible to the disease. “This is the first time...
